Benefits of Solar Water Heaters

Solar water heaters have many benefits, such as:

Energy Savings

One of the main benefits of solar water heaters is that they can reduce electricity consumption and bills by using free and renewable solar energy to heat water. According to a study by The Energy and Resources Institute (TERI), a typical household in India can save up to 1500 kWh of electricity per year by using a solar water heater of 100 liters capacity. This translates to an annual saving of about Rs. 12,000 on electricity bills, assuming an average tariff of Rs. 8 per kWh.

Solar water heaters can also reduce peak load demand and avoid power cuts, as they reduce the dependence on conventional electricity sources for heating water. This can improve the reliability and quality of power supply, and also reduce the need for expensive diesel generators or inverters.

Environmental Benefits

Another benefit of solar water heaters is that they can reduce greenhouse gas emissions and air pollution by replacing fossil fuels or conventional electricity sources for heating water. According to TERI, a typical household in India can avoid emitting about 1.5 tonnes of carbon dioxide per year by using a solar water heater of 100 liters capacity.

Solar water heaters can also contribute to climate change mitigation and adaptation efforts, as they reduce the vulnerability of the users to rising fuel prices and extreme weather events. They can also help in achieving the national and international targets for renewable energy and emission reduction, such as the National Solar Mission and the Paris Agreement.

Social Benefits

Solar water heaters can also create local jobs, improve healthcare and communications, and drive local commerce through the market and industry they build at the local level. According to a report by International Renewable Energy Agency (IRENA), the global solar thermal industry employed about 672,000 people in 2015, and is expected to create more jobs in the future as the demand for solar water heaters increases.

Solar water heaters can also enhance energy security and access for rural and remote areas, where grid electricity or fossil fuels may not be available or affordable. They can provide hot water for various purposes, such as cooking, bathing, washing, cleaning, sterilizing, etc., which can improve the quality of life and health of the people.

Costs of Solar Water Heaters

Solar water heaters have some costs, such as:

Initial Investment

One of the main costs of solar water heaters is their higher upfront cost than conventional water heaters, depending on the type, size, quality, and installation of the system. They also require additional components, such as pumps, controllers, pipes, valves, etc., which add to the initial cost.

According to MNRE, the average cost of a solar water heater of 100 liters capacity ranges from Rs. 15,000 to Rs. 35,000 for flat plate systems, and from Rs. 25,000 to Rs. 45,000 for evacuated tube systems. The cost may vary depending on the location, manufacturer, dealer, etc.

Maintenance and Operation

Another cost of solar water heaters is their regular maintenance and cleaning to ensure optimal performance and durability. They may also need backup systems or supplementary heating in case of low solar radiation or high hot water demand. These costs may include:

Cleaning the collector and the tank periodically to remove dust, dirt, bird droppings, etc.

Checking and replacing the fluid, valves, pipes, pumps, controllers, etc., as per the manufacturer's instructions.

Providing adequate insulation and protection for the system from weather, theft, vandalism, etc.

Using an electric or gas heater to supplement the solar water heater during cloudy days or peak hours.

According to MNRE, the annual maintenance cost of a solar water heater of 100 liters capacity is about Rs. 500 for flat plate systems, and Rs. 300 for evacuated tube systems. The cost may vary depending on the usage, location, service provider, etc.

Return on Investment of Solar Water Heaters

The return on investment of solar water heaters can be calculated by considering the benefits and costs mentioned above. The return on investment can be expressed in terms of payback period or net present value.

Payback Period

The payback period is the time required to recover the initial investment of a solar water heater through savings on electricity bills. It can be calculated by dividing the initial investment by the annual savings.

For example, let us assume that a household in Coimbatore buys a flat plate solar water heater of 100 liters capacity from Jupiter Solar, a leading manufacturer and supplier of solar water heaters in India. The cost of the system is Rs. 25,000 (including installation), and the household gets a capital subsidy of Rs. 6,600 from MNRE. The net initial investment is Rs. 18,400.

The household uses 100 liters of hot water per day at an average temperature of 60°C. The electricity tariff is Rs. 8 per kWh. The annual electricity consumption for heating water using an electric geyser is 1500 kWh. The annual electricity bill for heating water using an electric geyser is Rs. 12,000.

The annual electricity consumption for heating water using a solar water heater is negligible (assuming sufficient solar radiation and backup system). The annual electricity bill for heating water using a solar water heater is zero.

The annual savings on electricity bills by using a solar water heater is Rs. 12,000.

The payback period of the solar water heater is:

Payback period = Initial investment / Annual savings = Rs. 18,400 / Rs. 12,000 = 1.53 years

This means that the household can recover its initial investment in less than two years by using a solar water heater.

Net Present Value

The net present value (NPV) is the difference between the present value of the benefits and the present value of the costs of a solar water heater over its lifetime. It can be calculated by discounting the future cash flows by a suitable discount rate.

Return on Investment of Solar Water Heaters

The return on investment of solar water heaters can be calculated by considering the benefits and costs mentioned above. The return on investment can be expressed in terms of payback period or net present value.

Payback Period

The payback period is the time required to recover the initial investment of a solar water heater through savings on electricity bills. It can be calculated by dividing the initial investment by the annual savings.

For example, let us assume that a household in India buys a flat plate solar water heater of 100 liters capacity from a leading manufacturer and supplier of solar water heaters in India. The cost of the system is Rs. 25,000 (including installation), and the household gets a capital subsidy of Rs. 6,600 from MNRE. The net initial investment is Rs. 18,400.

The household uses 100 liters of hot water per day at an average temperature of 60°C. The electricity tariff is Rs. 8 per kWh. The annual electricity consumption for heating water using an electric geyser is 1500 kWh. The annual electricity bill for heating water using an electric geyser is Rs. 12,000.

The annual electricity consumption for heating water using a solar water heater is negligible (assuming sufficient solar radiation and backup system). The annual electricity bill for heating water using a solar water heater is zero.

The annual savings on electricity bills by using a solar water heater is Rs. 12,000.

The payback period of the solar water heater is:

Payback period = Initial investment / Annual savings = Rs. 18,400 / Rs. 12,000 = 1.53 years

This means that the household can recover its initial investment in less than two years by using a solar water heater.

Net Present Value

The net present value (NPV) is the difference between the present value of the benefits and the present value of the costs of a solar water heater over its lifetime. It can be calculated by discounting the future cash flows by a suitable discount rate.

For example, let us use the same assumptions as before, and assume that the discount rate is 10% per annum, and the lifetime of the solar water heater is 15 years. The future cash flows are:

Year 0: -Rs. 18,400 (initial investment)

Year 1 to 15: +Rs. 12,000 (annual savings)

The NPV of the solar water heater is:

NPV = -Rs. 18,400 + Rs. 12,000 / (1 + 0.1) + Rs. 12,000 / (1 + 0.1)^2 + ... + Rs. 12,000 / (1 + 0.1)^15 = Rs. 55,472

This means that the household can earn a net profit of Rs. 55,472 by using a solar water heater over its lifetime.

Comparison with Other Alternatives

The return on investment of solar water heaters can be compared with other alternatives, such as electric geysers or gas heaters, to see which option is more economical and beneficial.

For example, let us assume that an electric geyser costs Rs. 5,000 (including installation), consumes 2 kWh of electricity per day, has a lifetime of 10 years, and requires no maintenance or operation cost. The payback period and NPV of the electric geyser are:

Payback period = Initial investment / Annual savings = Rs. 5,000 / Rs. 0 = Infinity

NPV = -Rs. 5,000 + Rs. 0 / (1 + 0.1) + Rs. 0 / (1 + 0.1)^2 + ... + Rs. 0 / (1 + 0.1)^10 = -Rs. 5,000

This means that the electric geyser never pays back its initial investment and has a negative net value.

Similarly, let us assume that a gas heater costs Rs. 10,000 (including installation), consumes 2 kg of LPG per day at a price of Rs. 50 per kg, has a lifetime of 10 years, and requires no maintenance or operation cost. The payback period and NPV of the gas heater are:

Payback period = Initial investment / Annual savings = Rs. 10,000 / Rs. (-36,500) = -0.27 years

NPV = -Rs. 10,000 + Rs (-36,500) / (1 + 0.1) + Rs (-36,500) / (1 + 0.1)^2 + ... + Rs (-36,500) / (1 + 0.1)^10 = -Rs. 2,02,857

This means that the gas heater pays back its initial investment in less than a year, but has a very negative net value.

From the above calculations, it is clear that the solar water heater has the highest return on investment among the three options, and is the most economical and beneficial choice for heating water.

Conclusion

In this article, we have tried to answer the question of whether purchasing solar water heater is beneficial economically especially considering initial investment. We have looked at the various benefits and costs of solar water heaters, and how to calculate their return on investment. We have also compared the solar water heater with other alternatives, such as electric geysers or gas heaters.

We have found that solar water heaters have many benefits, such as energy savings, environmental benefits, and social benefits. They also have some costs, such as initial investment, maintenance and operation, and subsidies and incentives. However, the benefits outweigh the costs, and the solar water heater has a high return on investment in terms of payback period and net present value.

We have also found that solar water heaters are more economical and beneficial than electric geysers or gas heaters, which have low or negative return on investment.

Therefore, we can conclude that purchasing solar water heater is beneficial economically especially considering initial investment, and we recommend that potential buyers consider this option for heating water.

Excerpt from this Op-Ed from the New York Times:

To keep the lights on, many utility companies are proposing to build dozens of new power plants that burn natural gas. North Carolina-based Duke Energy alone wants to add 8.9 gigawatts of new gas-fired capacity — more than the entire country added in 2023. Using their own projections of soaring energy demands as justification, these companies are also pushing back on the climate targets set by their states and the Biden administration.

If state regulators sign off on these plans, they will be gambling with our country’s future. We need to electrify everything from cars to appliances to slow climate change, but we won’t be able to reach our climate goals if we power all of those machines with dirty energy.

There is a better way. But to get there, legislators will need to overhaul the incentives driving utilities to double down on natural gas, so that they can turn a profit without cooking the planet.

Companies like Duke, Dominion Energy and Georgia Power argue that they need more gas-fired plants to reliably provide power during times of peak demand — for instance, on a hot summer weekday afternoon when home cooling systems and data servers are all humming at maximum output, and the grid strains to keep up. But those peaks tend to materialize only for a few dozen hours per year, and there are ways to deal with them that don’t require a massive amount of new methane-burning infrastructure.

The real reason the utilities want to build these plants is quite simple: The more stuff they build, the more money they make. Regulators let utilities charge their customers enough money to cover what they spend on assets like combustion turbines and wires, plus a generous rate of return (up to 10 percent) for their investors. This longstanding arrangement incentivizes power providers to build expensive things whether society needs them or not, in lieu of lower-cost, cleaner options, and to invoke their duty to keep the lights on as a post hoc rationalization.

Fortunately, utilities have plenty of ways to meet this new need.

They include “virtual power plants” — when technologies such as home batteries, rooftop solar systems, smart water heaters and thermostats are linked together and managed via software to provide the same services as a conventional power plant. Utilities in Vermont, Colorado and Massachusetts are already using them, to quickly respond to rising demand at a much lower cost than operating natural gas combustion turbines. According to one estimate, virtual power plants could lower U.S. utilities’ costs by as much as $35 billion over the next decade.

Utilities could also accelerate efforts to replace outdated transmission lines with newer ones that can carry double the electric current and to bring more battery storage online. They can compensate customers for using less energy during times when demand is high and invest far more in energy efficiency, helping customers to adopt devices that use less electricity.

All of these solutions would save customers money and reduce carbon emissions. They could, according to a Department of Energy analysis, meet the entire projected growth in U.S. peak electricity demand over the next decade.

Energy-Efficient Building Techniques in Tarneit

In reaction to the global movement towards sustainability, the construction industry in Tarneit, an emerging suburb of Victoria, has been integrated. In particular, house builders Tarneit can incorporate sustainable and efficient methods, materials, and technologies in building construction. 

These methods benefit the environment and are also financially sustainable for homeowners as they help cut down costs incurred in the provision of energy. This blog evaluates the various high-quality, energy-efficient building methods defining future housing in Tarneit.

Solar Power Integration

Integrating solar power systems is one of the most significant steps towards energy-efficient building. House builders in Tarneit increasingly embed solar panels and thermal systems in new constructions. Solar panels capture solar energy and directly convert it into electricity. 

Solar thermal structures harness sun energy to warm water, which reduces the use of steam on non-renewable power assets. This cuts carbon emissions and hence supports the environment while lowering utility expenses. 

Additionally, promoting incentives for solar power in Australia attracts new homeowners to embrace this power source.

Advanced Thermal Insulation

Proper insulation, therefore, plays a significant role in energy conservation, whereby temperatures within homes are well regulated, lowering the chances of using heaters or air conditioners frequently. House builders in Tarneit employ advanced insulation techniques, including foam insulation and high-quality batten insulation.

These materials are installed in the walls, roofs and floors as insulation and resist heat flow in cold and hot seasons. Insulation is crucial for making homes more comfortable by significantly reducing noise levels.

High-Efficiency Windows

Another strategy house builders in Tarneit use is installing energy-efficient windows to enhance home energy performance. Multiple-glazed or triple-glazed windows are made up of several glass panes separated by a gas with very low thermal conductivity. 

These windows also play a part in controlling indoor temperatures, preventing the formation of condense and giving better soundproofing. 

The frames employed in making these conservatories include fibreglass or composite frames, which are more energy-efficient and long-lasting.

Water-Saving Fixtures

Water performance in buildings is now considered one of the predominant additives of sustainable construction. In today's Tarneit homes, newer and more innovative houses feature energy and water-saving amenities such as low-flow toilets, showerheads, and faucets. 

Experienced house builders in Tarneit prefer these fixtures to minimise water usage in daily life while maintaining functionality without achieving high levels of water usage. 

By using significantly less water per minute compared to traditional fixtures, they help conserve a critical natural resource and lead to substantial savings on water bills. 

The deliberate incorporation of water-efficient technology in homes demonstrates a commitment to environmental stewardship and economic efficiency.

Use of Sustainable Materials

The desire for building materials plays a vital function in the environmental effect of a construction undertaking. House builders in Tarneit use recycled building materials that are not obtained directly from the source and have been recycled first. Some sustainable materials used in construction include recycled steel, glass, re-use wood and bamboo. 

Also, paints and adhesives are non-toxic, and sealants are used to reduce the emissions of VOCs, which harm the inhabitants of homes by providing them with good air quality.

Implementation of Smart Home Technology

Smart home technology is crucial today and significantly affects home energy management. Some of the features in houses in Tarneit include intelligent thermostats that control heating and cooling equipment depending on the number of people using the house and the climate. 

For instance, LED lighting consumes less energy than traditional lighting; programmable appliances and water heaters also help save energy. These technologies allow owners to screen their power consumption behaviour in detail and, for this reason, be in a function to make rational selections.

Green Roofs and Living Walls

Some innovative house builders in Tarneit are incorporating green roofs and living walls into new constructions. These characteristics provide good thermal performance, minimise the speed and impact of water on buildings, contribute to air quality, and diversify the avian fauna within cities. 

A green roof is a vegetative layer covered with vegetation and a growing medium or partially or fully developed plant layer on a waterproofing layer. 

Similarly, living walls are part of the building's exterior or interior walls, covered with plants. They enhance a building’s insulation and add aesthetic value to the property.

Optimal Orientation and Layout

This is a fact because the position of a building and its architecture determine how much energy it will consume. Climatically responsive architecture is apparent, where house builders in Melton strategically place numerous windows and doors to maximise natural light and air circulation within the buildings. 

Additionally, the structures are oriented in alignment with the direction of the winds and the sun. This approach minimises using artificial lights and mechanical air conditioners, thus saving power. 

Such thoughtful placement enhances energy savings and ensures that living spaces maintain a natural comfort throughout the seasons, creating healthier and more sustainable living environments.

Final Takeaway

Thus, the residents of Melton who choose to live in a house constructed with the following features can have a relatively environmentally friendly way of life meeting the ecological requirements of the contemporary world. Various dedicated house builders in Melton are adopting these building practices, paving the way for a future where all newly constructed homes will be as energy-efficient as possible, reflecting a commitment to environmental responsibility and sustainability.

Just moved into a house that has an electric hot water heater and after monitoring the electric usage for a few days it became apparent that the hot water heater was driving the overwhelming majority of the usage of electricity. Our electric bill was on target to be around $130/month from usage alone (more for the customer charge), but after a few innovations we reduced our daily usage to where it's now set to average closer to $90/month for usage.

The temperature on the hot water heater was already turned down to the safest setting (120°F); you don't want to go any lower than this because harmful bacteria can start growing in the tank. In one previous apartment I lived in, the temperature was set higher, and we were able to lower it which saved about $15 a month.

Some of the innovations we made this time around include:

In the kitchen where there is a single faucet that you can turn to the left for hot and right for cold, we had been leaving the faucet in the middle most of the time, which was using a blend of hot water. We often wouldn't notice the waste because we'd just use the tap for a short burst of water, so the water wouldn't run long enough to get hot. But it was still wasting hot water, drawing it out of the tank to where new water needed to be heated. To address this, we started turning the handle the whole way to the right and we only ever turn it to the left when we specifically need hot water; otherwise we keep it the full way to the right.

I started using cold water for some usages where hot water wasn't strictly necessary.

I started taking cooler showers, going as cold as was comfortable for me, which in the summer heat was pretty easy.

In the long-run we've considered other innovations, such as adding more insulation along the hot water pipes coming out of the boiler, and also looking into potentially replacing it, such as with a heat-pump hot water heater or a solar one, both of which can yield huge savings.

We also considered getting a new showerhead with a detachable head and a setting that only runs water when you hold down a button. For example you can lather up with soap or shampoo and then only run the water to wash it off. This hugely reduces all water usage, including hot water if the settings are on hot. The cost of hot water with an electric hot water heater is much higher than the cost of water itself, so the savings on hot water alone by doing this can be huge. I'm not sure how much this stuff is going to save but I'm optimistic given that we seem to have already reduced our usage enough to save about $40 a month.

Even if you live at home with parents, or in an apartment where hot water is included in your rent, someone is paying for hot water. In the long-run, rent tends to go up as expenses go up so a lot of these expenses get passed on to tenants anyway, so you aren't necessarily just making your landlord richer by conserving: it can actually help to keep rents down for all tenants if you conserve hot water. You can also talk to your landlord about innovations like turning down the temperature of the water (which has other benefits like reducing scalding risk, which a landlord might care about because it could be a potential point of liability if someone is burned by water that was too hot) until it is around 120°F. In most apartments you can also just buy and install your own showerhead, most can be installed just by screwing off the old one, then if you want to take it with you you can just put the old one back on when you move out, or you can leave it for the next tenant to enjoy.

Are You Interested in Knowing a Brief History About the Tankless Water Heater?

Well here is an article on its details and history that would make your knowledgeable about the product. You can also opt to buy for it for better convenience.

With several advantages over conventional tank-style water heaters, tankless water heaters, sometimes referred to as on-demand or instant water heaters, can be a great long-term investment. The first water heater was a gas tankless (instantaneous) heater, which was created in 1889 and introduced to the US market in 1893. Tankless water heaters were just not technologically advanced enough to provide a competitive alternative to the traditional water heater industry in America until the 1970s.  In 1929, Stiebel-Eltron created the first electric tankless water heater. A pioneering immediate form of water heater was the bath heater.

The tankless water heater is becoming more and more popular nowadays because it's difficult to envision life without instant access to hot water.

The Operation of a Tankless Water Heater

Tankless water heaters don't store hot water like conventional water heaters do, which do so in a tank. They instead offer hot water on demand. They are sometimes referred to as on-demand or demand-type water heaters for this reason.

The water heater's sensor determines the water demand when you turn on the faucet. The device then draws cold water from your home's main supply and determines how fast the cold water will flow in as well as how much energy will be necessary to heat the water to the desired temperature. The system then draws the necessary amount of power. Depending on the design, tankless water heaters can be powered by electricity, gas, propane, or even oil.

When to Consider Removing Your Tank-Water Heater

Tankless water heaters are a good option if you:

Want to significantly lower your long-term water heating costs?

Run out of hot water frequently

Have a hot tub, bathroom, or other use that is far from your current water heater

Having trouble getting enough hot water for your dishwasher or washing machine?

A backup is required for your solar water heater.

Benefits That You Must Consider

Their biggest benefit comes from this on-demand mode of operation: lower energy and operating expenses. Buy electric tankless water heater for your home to get these benefits.

There are numerous benefits to choosing a tankless water heater over a conventional tank-style heater in addition to energy and financial savings. In addition to providing an unending supply of hot water, tankless water heaters are safer, use less room, are less likely to leak, and have a substantially longer lifespan than conventional water heaters.

Each tankless water heater has a limited flow rate, which means that it can only heat a specific volume of water at once. The major concern associated with tank-style heaters is the accumulation of minerals from hard water inside the tank over time, which can cause corrosion and eventually leaks.

There is zero chance of leaks or flooding with tankless water heaters because there is no tank.

Additionally, because tankless water heaters don't keep a supply of water in a tank that is corroding, the water they distribute throughout your home is purer and safer for the skin.

Neo-Atlantis Codex: Part III: Grid Storage

So, you want to use some unstable form of power. Wind and Solar are the biggest ones, but we could also add tidal and microhydro to the list.

Currently, 95% of grid power storage, world wide, is pumped hydro. This is in theorygood, as it does work. The problem is that regions that can use pumped hydro will typically have geography to use regular hydro, which is very, very, very efficient. But you can add pumped hydro to an existing system.

For home power storage, we use chemical cells. Typically Lithium. By current estimates, we do not have enough lithium and cobalt in the world to replace our cars, nevermind the entire grid. A lot of the mining is also done by child slaves in Africa. They also use water leeching, which works. but also uses a LOT of fresh water. It's often done in deserts, in which fresh water is the most precious thing you can have.

Lithium is also EXTREMELY flammable.

What about other chemicals? Well, we can make chemical cells out of salt water and iron. This used to require a pump, and which made it hard to miniaturize. Anything mechanical is also prone to mechanical breakdown. They have recently developed technology to elimitate the use of pumps. It's still not good for grid storage, but would be good for home power storage. It might make sense to move to a paradigm that the state provides power when it can, and homes had to store their own power. This would work, although it would require a complete change of our paradigm, and would be expensive for the poor. Which is the problem for anything to do with power, as any increase in energy cost punishes the poor, and will drop people into poverty. It will also kill off the vulnerable.

Earth Batteries. You take something with a high durability and heat capacity, like earth, stone, brick, etc. You put it inside an insulated shell. You have a heater inside. Power added from the outside becomes heat inside. The heat can be kept for a week without too much loss. You can either use this directly for heat, or use it to heat water into steam. Doing so would allow it to produce electricity. This is suitable for neighbourhoods or industrial applications. The problem with a steam engine is that you would likely need a steam engineer, which are expensive. It would also require individual neighbourhoods to be self-governing villages/shires, which would help with so many other problems. We'll talk about this later in Neo-Atlantis government/electoral system. This would reduce the work required from other parts of the power system, and in theory, in some areas, these neighbourhoods/villages/shires/wards could be entirely self-generating. If California could shed it's horrifying Fascist control, it has more than enough sunlight that individual neighbourhoods could be self-generating if it could store the power. This would also prevent blackouts. Everytime I look back, it gets further way, but in 2003, the entire Eastern side of Canada, and the New England had a power outage. Because of how connected the grids are. Independent neighbourhood production would completely eliminated this. If you had a tree down over the power lines, it would hurt at most, one neighbourhood.

Compressed air storage. The best usage of this is, funny enough, CO2. You have a giant balloon, kind of an expanding membrane. You hook it up to a pump and a turbine and heat exchanger. Power causes the pump to pump the CO2 from the balloon into the tank. You release CO2 from the tank through the turbine, and it produces power. The big drawback for this is that it requires a lot of space. Which makes it perfect for isolated solar / wind power plants. This also requires nothing in the way of novel technology, and is perfect for large grid storage.

Hydrogen. Contrary to expectations, hydrogen fuel cells never went away. Both Toyota and Hyundai have production Hydrogen fuel cell cars. Hydrogen combustion cars are also perfectly viable, if not currently commencial. Hydrogen can be produced from water through electrolysis, though not efficiently so. It can be produced mechanically from natural gas / methane; the mechanical converters use a portion of the power they produce to power themselves. Before the government were... what?.. afraid the fuel cells might actualy work? I'm old enough to remember the promise of a Hydrogen Highway from California to British Columbia to allow you to drive hydrogen fuel cell cars up and down the coast. Well, they forgot about that. Before this happened, there was a research group that made it with algae in glass tubes. All you needed to do was pump water through them. People in California could probably add it to a closed system in their car.

Synthetic Fuel. Synthetic fuel has been used, in a small scale, in racing for years. Formula 1 is also planning to replace it's entire usage with synthetic fuel in the future, apparently from atmospheric carbon dioxide and wind power. This would have the advantage of requiring no time or money to implement. It would use our existing fuel infrastructure, while also allowing the small producers to be created everywhere.

BIPV Market: Trends Supplement Large-Scale Solar Systems Adoption

As per the International Energy Outlook, the global power demand is expected to rise by 80%, requiring an investment of around $19.7 trillion by 2040. Also, the Paris Agreement set a target of limiting global warming temperature below 2° Celsius, preferably 1.5° Celsius. This has influenced governments to seek innovative ways to reduce emissions while meeting energy demand, which has paved the way for photovoltaic materials in buildings. Triton’s analysis estimates that the global building integrated photovoltaics market will propel at a CAGR of 17.31% during the forecast period 2023-2030.

Building integrated photovoltaics serves the dual purpose of being the outer layer of a building and a power generator. This, in turn, has opened a new frontier in green infrastructure, influencing architects to develop energy-efficient and aesthetically appealing buildings. For instance, Ubiquitous Energy’s transparent solar window panels, UE Power, have emerged as an aesthetically appealing power-generating alternative to conventional windows.

BIPV Revolution: Trends Reshape Energy Landscape

According to the International Renewable Energy Agency (IRENA) , around 90% of the world’s power can be generated with renewable energy by 2050. Since buildings consume high amounts of energy, BIPV integration will facilitate their transition from energy users to producers. On that note, the notable trends reshaping the market are:

Governments perceive investing in green energy solutions as an opportunity to attain GHG reduction targets. Hence, over the past few years, authorities worldwide have employed various measures to stimulate the adoption of sustainable technologies, including BIPV modules, across residential, commercial, and industrial sectors. For example:

As per the Indian Ministry of New & Renewable Energy (MNRE) , the government has implemented the production-linked incentive (PLI) scheme for high-efficiency solar PV modules with an outlay of INR 24,000 crore, to achieve domestic manufacturing capacity of solar PV cells and modules.

In 2021, the German government amended the Renewable Energy Act by establishing grid priority to drive the onshore wind, solar PV, and biogas growth. The government proposed to increase its solar capacity installations to 100 GW by 2030.

The Chinese government also formulated a policy that requires all new buildings to conform to energy guidelines modeled after LEED specifications. This policy combines a recent initiative to reconstruct 50% of residential high-rise buildings. The country is anticipated to add more than 600 GW of solar power by 2030.

Reaping the benefits from such incentives, the industrial sector leads the BIPV market at 39.54%. However, over the forecast period 2023-2030, the commercial sector is expected to witness the fastest growth at 17.38%.

As per IEA, the global solar PV generation reached around 821 TWh in 2020, a whopping 23% increase from 2019. The energy association also stated that next to utility-scale deployment, distributed applications on buildings contribute to around 40% of PV use globally. In this regard, rooftop-based applications are alleviating the burden on the distribution grids, enabling companies and households to pay lesser energy bills while reducing emissions. Moreover, the cost of installing rooftop PV systems reached around $1 per watt. Hence, roofing captures the majority of the market share at 55.69% in terms of application.

China drives the global market, followed by the US, European nations, and Japan playing a major role. The rise in installations from around 19.4 GW in 2017 to 27.3 GW in 2021 was the key aspect that made China a leader in rooftop installations. For instance, Shanghai and Dezhou have acquired the title of ‘Solar City’, which features a large fleet of rooftop solar water heaters. Besides, the Net Zero Energy Building mandate across China is expected to accelerate the PV roofing segment, with solar tiles gaining major traction. Hence, these developments are expected to widen the scope of the Asia-Pacific BIPV market over the forecast period 2023-2030.

IEA projects that photovoltaic systems are estimated to account for approximately 14% of the total power generation by 2050, owing to the rising detrimental impact of fossil fuels. In fact, the organization stated that PV systems saved more than 860 million tons of C02 in 2020. The construction industry is highly innovative in the commercial sector owing to the development of cost-effective zero-emission green facilities.

As per IRENA, Germany ranks fourth in solar energy production globally. In 2021, the nation installed solar capacities of almost 60 GW, an increase of 5.3 GW from 2020. These actions are based on the country’s aim to obtain a 65% share of the renewable energy sector by 2030. Moreover, the Energy Efficiency Strategy for Building suggested advanced technology development to achieve the goal of a virtually climate-neutral building stock by 2050. Hence, the growing focus on sustainable energy sources fuels the overall Europe BIPV market, spearheaded mainly by Germany.

PV Cost Reduction: A Driving Force for Market Players

Since photovoltaic systems generate energy with around 42% efficiency using multi-junction cells, they have emerged as an ideal alternative over complex installations, such as wind turbines. As per the UN, between 2010 to 2020, the cost of power from solar systems plummeted by around 85%. This highlights the question:

What induced PV cost reduction?

The significant cost decline is mainly because of overproduction and higher investment in PV modules. Another factor is the efforts by Chinese suppliers and wholesalers to reduce the stock held in European warehouses to prevent anti-dumping and anti-subsidy tariffs. This oversupply, from China to Europe thus shrunk the cost of silicon. Such developments led energy solutions supplier Sungrow to supply products to the world’s largest BIPV plant (120 MW) in Central China’s Jiangxi Province. Therefore, the increasing efficiency, ease of installation, and decreasing cost of PV modules over conventional sources like coal and natural gas are expected to open new avenues for players in the building integrated photovoltaics market.

Custom Tankless Water Heater Installations: Shaping the Future of Home Efficiency

As energy efficiency and sustainability become priorities for modern households, custom tankless water heater installations are transforming how homes access hot water. These innovative systems provide an eco-friendly alternative to traditional water heaters by heating water on demand, optimizing energy use, and ensuring reliable performance tailored to individual needs. With numerous benefits, including reduced energy waste and long-term cost savings, tankless water heaters are leading the charge toward a smarter, greener future.

Why Custom Tankless Systems Stand Out

Traditional water heaters store and heat a large tank of water continuously, often wasting energy when hot water isn’t in use. Tankless systems, on the other hand, heat water only when it’s needed. This on-demand functionality significantly reduces energy consumption and prevents common problems like heat loss in storage tanks.

Custom installations take these advantages further by designing the system to suit your specific household needs. Variables such as water usage patterns, home size, and the number of occupants are carefully analyzed to ensure the system operates at peak efficiency. For larger families, high-capacity models or multiple units may be installed to meet demand without strain. Conversely, smaller households can benefit from compact systems that save space while still providing consistent hot water.

The Long-Term Advantages of Going Tankless

Opting for a custom tankless water heater offers a range of benefits beyond energy efficiency. Financial savings are among the most compelling reasons to make the switch. Tankless systems consume less power than conventional models, leading to noticeable reductions in utility bills over time. While the initial investment may be higher, the long-term cost savings make it a worthwhile decision for budget-conscious homeowners.

Durability is another advantage of these modern systems. Traditional water heaters often suffer from sediment buildup, leaks, and tank corrosion, which can shorten their lifespan. In contrast, tankless models avoid these issues, typically lasting up to 20 years with proper maintenance. By incorporating features like water filtration or descaling systems during installation, homeowners in areas with hard water can further extend the unit’s life.

Sustainability Meets Convenience

For environmentally conscious homeowners, tankless water heaters align perfectly with green living goals. By using energy only when hot water is needed, these systems drastically reduce greenhouse gas emissions and overall energy consumption. Many models also integrate seamlessly with renewable energy sources like solar panels, providing even greater environmental benefits.

Additionally, tankless systems improve daily convenience by delivering unlimited hot water without the delays or shortages often associated with traditional heaters. Their compact design frees up valuable space in your home, making them an ideal choice for modern living. Investing in a custom installation ensures your system adapts to your unique lifestyle, delivering both immediate and long-term rewards.

Custom tankless water heaters are more than just an upgrade—they’re a commitment to efficiency, sustainability, and comfort. By selecting a system tailored to your needs, you’ll enjoy the perfect balance of performance, cost savings, and environmental responsibility. Make the shift today to embrace the future of home efficiency.

Excerpt from this story from the New York Times:

In February, the United States did something that it had not done in many years — the country sent more electricity to Canada than it received from its northern neighbor. Then, in March, U.S. electricity exports to Canada climbed even more, reaching their highest level since at least 2010.

The increasing flow of power north is part of a worrying trend for North America: Demand for energy is growing robustly everywhere, but the supply of power — in Canada’s case from giant hydroelectric dams — and the ability to get the energy to where it’s needed are increasingly under strain.

Many energy experts say Canadian hydroelectric plants, which have had to reduce electricity production because of a recent drop in rain and snow, will eventually bounce back. But some industry executives are worried that climate change, which has already been linked to the explosive wildfires in Canada last year, could make it harder to predict when rain and snowfall will return to normal.

“We’ve all got to be humble in the face of more extreme weather,” said Chris O’Riley, president and chief executive of the British Columbia Hydro and Power Authority, which operates hydroelectric dams in western Canada. “We manage from year to year the ups and downs of water, and when we have the downs like we’re having, the lower levels, it’s common for us to import power, and we expect to continue that this year.”

The United States and Canada have long relied on each other because power use tends to peak north of the border during the winter when Canadians use electric heaters, and American electricity use peaks in the summer during air-conditioning season.

The abundance of Canada’s hydroelectric power has been a cornerstone of the trade, providing relatively low-cost renewable energy to California, Oregon, Washington State, New York State and New England.

But the supply-and-demand equation for energy is changing. Demand for electricity in many states has been climbing sharply in summer and winter. Some experts predict that winter electricity demand in the United States could eclipse summer demand by 2050.

At the same time, utilities are increasingly reliant on intermittent resources like solar and wind power. Large hydroelectric plants, once considered a stable source of electricity, have struggled with low reservoirs in California, around Hoover Dam and recently in Canada.

“We are facing real changes in the weather, and we’re finding out in real time how that’s going to affect hydroelectric operations, pretty much across North America,” said Robert McCullough of McCullough Research, a firm based in Portland, Ore., who has been a consultant for corporate customers of Canadian utilities since the 1980s.
