#solar panels 20 watt

[reasonsforhope]

"This year the world will make something like 70bn of these solar cells, the vast majority of them in China, and sandwich them between sheets of glass to make what the industry calls modules but most other people call panels: 60 to 72 cells at a time, typically, for most of the modules which end up on residential roofs, more for those destined for commercial plant. Those panels will provide power to family homes, to local electricity collectives, to specific industrial installations and to large electric grids; they will sit unnoticed on roofs, charmingly outside rural schools, controversially across pristine deserts, prosaically on the balconies of blocks of flats and in almost every other setting imaginable.

Once in place they will sit there for decades, making no noise, emitting no fumes, using no resources, costing almost nothing and generating power. It is the least obtrusive revolution imaginable. But it is a revolution nonetheless.

Over the course of 2023 the world’s solar cells, their panels currently covering less than 10,000 square kilometres, produced about 1,600 terawatt-hours of energy (a terawatt, or 1tw, is a trillion watts). That represented about 6% of the electricity generated world wide, and just over 1% of the world’s primary-energy use. That last figure sounds fairly marginal, though rather less so when you consider that the fossil fuels which provide most of the world’s primary energy are much less efficient. More than half the primary energy in coal and oil ends up as waste heat, rather than electricity or forward motion.

What makes solar energy revolutionary is the rate of growth which brought it to this just-beyond-the-marginal state. Michael Liebreich, a veteran analyst of clean-energy technology and economics, puts it this way:

In 2004, it took the world a whole year to install a gigawatt of solar-power capacity... In 2010, it took a month In 2016, a week. In 2023 there were single days which saw a gigawatt of installation worldwide. Over the course of 2024 analysts at BloombergNEF, a data outfit, expect to see 520-655gw of capacity installed: that’s up to two 2004s a day...

And it shows no signs of stopping, or even slowing down. Buying and installing solar panels is currently the largest single category of investment in electricity generation, according to the International Energy Agency (IEA), an intergovernmental think-tank: it expects $500bn this year, not far short of the sum being put into upstream oil and gas. Installed capacity is doubling every three years. According to the International Solar Energy Society:

Solar power is on track to generate more electricity than all the world’s nuclear power plants in 2026 Than its wind turbines in 2027 Tthan its dams in 2028 Its gas-fired power plants in 2030 And its coal-fired ones in 2032.

In an IEA scenario which provides net-zero carbon-dioxide emissions by the middle of the century, solar energy becomes humankind’s largest source of primary energy—not just electricity—by the 2040s...

Expecting exponentials to carry on is rarely a basis for sober forecasting. At some point either demand or supply faces an unavoidable constraint; a graph which was going up exponentially starts to take on the form of an elongated S. And there is a wide variety of plausible stories about possible constraints...

All real issues. But the past 20 years of solar growth have seen naive extrapolations trounce forecasting soberly informed by such concerns again and again. In 2009, when installed solar capacity worldwide was 23gw, the energy experts at the IEA predicted that in the 20 years to 2030 it would increase to 244gw. It hit that milestone in 2016, when only six of the 20 years had passed. According to Nat Bullard, an energy analyst, over most of the 2010s actual solar installations typically beat the IEA’s five-year forecasts by 235% (see chart). The people who have come closest to predicting what has actually happened have been environmentalists poo-pooed for zealotry and economic illiteracy, such as those at Greenpeace who, also in 2009, predicted 921gw of solar capacity by 2030. Yet even that was an underestimate. The world’s solar capacity hit 1,419gw last year.

-via The Economist, June 20, 2024

--

Note: That graph. Is fucking ridiculous(ly hopeful).

For perspective: the graph shows that in 2023, there were about 350 GW of solar installed. The 5-year prediction from 2023 said that we'd end up around 450 GW by 2030.

We hit over 600 GW in the first half of 2024 alone.

This is what's called an exponential curve. It's a curve that keeps going up at a rate that gets higher and higher with each year.

This, I firmly believe, is a huge part of what is going to let us save the world.

[cenabisbene]

So I went ahead and did some rough math based on the roof areas from this site: https://weprintwraps.com/wp-content/themes/weprintwraps/files/pvo_square_footage_list.pdf

So your average small car has about ~20sqft of roof area, while your larger car gets up to ~35-40sqft. Your average home solar panel is about 15 sqft and produces between 200 and 350 W max power. You're not going to be getting max power from a panel lying flat on your roof (which you're going to want to do otherwise the drag will be horrendous) so let's say you're going to average 100 W over the span of an 8-hour workday parked in the sun on a small car, double that on a big car.

So that's 800-1600 watt-hours (Wh). What can you do with that? Well depending on who you believe (basically the carmakers or the EPA), your electric car can get between 2 and 4 miles per kWh. So over the course of the workday, you're going to be able to charge your car enough to go about a mile and a half, maybe three miles if you're in really good conditions. Maybe you can stretch that to five miles if you're planning on limping home at 5-10 mph.

So that means if you're stranded six miles from home you will need to let it charge for two days before you have enough power to drive home. Don't forget that if it's cold out, it's likely either because it's cloudy or winter, so you're going to get a lot less than 100 W average out of your panels due to the angle of the sun or the clouds blocking the sun.

The point I'm trying to make with this is that CARS ARE HORRENDOUSLY INEFFICIENT WAYS TO GET AROUND. The amount of weight that you're dragging around you when you drive is really difficult for people to accurately comprehend, and the amount of energy that it takes to get all that weight up to speed is, again, really difficult to wrap your head around.

By contrast, my electric bike on full throttle without any pedaling gets up to 22 mph and draws about 350 W, meaning that I can go more than 20 miles on my little battery that weighs six pounds and is the size of two bricks taped together. If the battery dies I can pedal it home! And if I really wanted to, I could fill the saddlebags with enough solar panels to fully charge it over the course of the work day!

And before anyone says "not everyone can ride a bike" or "what about the rain" there are people out there building electric trikes, recumbent bikes, and all sorts of other human-size electric vehicles that take up waaaay less space in the world than a car and get you where you want to go with a tiny fraction of the amount of energy it takes to haul a ton of steel and aluminum around the road at 35 mph.

tl;dr making a solar-panel-covered electric car is like putting lipstick on a slightly more polite pig, car-centricity is a cancer, get an ebike if you can

Okay also I’ve been driving electric cars long enough now to be really emphatic that the fact that they’re not all automatically built with solar panels in the roofs is a scandal.

And somehow almost every time I tell anyone this they roll their eyes and attempt to explain to me that this would not create a perpetual motion machine because of the limitations of the area relative to the power draw of the motor, which is incredibly annoying because that’s not the point.

Yes it’s possible that driving in the sunshine with a solar collector dripping into the battery would net you a little more mileage on that trip before needing recharge, but the usefulness of a solar-topped electric car is that if you drive it someplace–say, to work–and leave it outside in the sun all day, you’ll definitely have more range available by the time you’re ready to head home.

Also if you fuck up your calculations because of the inefficiency induced by cold weather or something and get yourself stranded without anywhere to charge, like halfway up a mountain or, more likely, six miles from home, you can call for rescue or walk away, come back later, and it’ll be able to move again.

This is important because unlike running out of gas you can’t really go get some electricity.

How Many Solar Panels Required for 1.5 Ton AC? | Zarea Limited

Introduction:

As the keeps growing requirement for renewable energy results in more companies and homes are thinking about converting their air conditioners to solar energy. Meanwhile one of the most frequently asked questions is “How many solar panels required for 1.5 ton AC?”. This article will offer a thorough response and take into account local factors. Which may include sunshine availability, panel wattage, energy usage, and solar system efficiency.

The average sunshine your area gets, the extent of shade around your residence, the kind of inverter installed, and the available roof space for solar panels all influence the number of solar panels required for a 1.5 tonne air conditioner. Let’s examine more closely how each of these elements affects your power generation and the specific requirements you need to fulfill for your air conditioning system.

Knowing How Much AC Power We Use:

The power consumption of a 1.5-ton air conditioner normally ranges from 1.5 kW to 2 kW per hour. It may also depends on the AC brand, energy efficiency rating (EER), and the type of inverter. Meanwhile both the solar panels and the air conditioner depend on the wattage of a solar system. These watts determine a 1.5-ton AC unit’s power consumption. Moreover, this will determine the capacity you should be dealing with.Type of ACApprox. Power Consumption (Per Hour)Inverter 1.5 Ton AC1.2 – 1.5 kWhNon-Inverter 1.5 Ton AC1.8 – 2.2 kWh

The AC would use around 12 to 16 units of power per day if it ran for eight hours every day.

Things to Take Into Account Before Solar System Sizing:

In order to calculate the required number of solar panels, we need to take into account:

Energy use per day (in kWh)

Daily average production from solar panels (depending on location)

Wattage of the panel

Efficiency of the system and possible energy losses (10–20%)

Grid-tie or battery backup system

How Much Power Can a Solar Panel Produce?

An average 330-watt solar panel produces around 1.5 units (kWh) of energy daily on a daily basis. Regions especially like the Middle East, India, or Pakistan where peak 4–5 sun hours are typical.

Thus:

1.5 kWh per day for one panel

15 kWh per day with 10 panels

How Many Solar Panels Does a 1.5-Ton AC System Need?

The wattage of solar panels you use and the length of time you want to operate the air conditioner will determine how many solar panels you need for a 1.5-ton AC with an inverter. Generally speaking, you require 10 to 12 250 watt solar panels to run an air conditioner of this size or a comparable system that can generate 3 to 5 kWh.

Assume:

AC consumes 2 kW per hour.

runs for eight hours every day.

Total consumption per day = 2 kW × 8 = 16 kWh

Every 330W panel produces about 1.5 kWh per day.

Without Direct Grid Tie (Battery Backup):

An off-grid system is a system that will only use solar energy. When it comes to air conditioning, this may restrict your usage to times of day when there is sunshine (unless you utilise a solar battery). An off-grid system uses solar energy exclusively. When it comes to air conditioning, this may restrict your usage to times of day when the sun shines (unless you utilize a solar battery). Although solar batteries can help you store energy for later use, you must consider future storage.

To reach 16 kWh per day:

10.6 panels (16 kWh / 1.5 kWh each panel)

Round up to 11 330W panels

Size of the entire system: 11 × 330W = 3.63 kW

Using a hybrid system with battery backup:

You must figure out how many hours you need to run your air conditioner and save up the required quantity of electricity if you want to really maximise the amount of sunshine you receive. This would entail having a more potent system that you could utilise when the sun is at its strongest and store the extra for later use.

Add inverter inefficiencies and 20% energy loss:

19.2 kWh/day (16 kWh × 1.2).

12.8 panels (19.2 / 1.5).

Round up to 13 330W panels

Size of the entire system: 13 × 330W = 4.29 kW

Performance-influencing factors:

Systems with solar panels can continue to operate at their best as long as you:

Make use of energy-efficient solar panels.

Decide on the best course for your solar panel installation. Roofs facing south are 10% more efficient than those facing north.

Reduce shade and increase sunlight.

Make the most of the roof space. A 3kW installation would need 17 to 21 meters of roof space. Fortunately, most homes in Pakistan can handle this.

Maintain the panels clean, make adjustments for seasonal variations (more on this later), and carry out solar panel maintenance correctly.

If the panels are on the roof instead of in the roof, you should space them apart from the roof to allow for cooling (7 inches between the panel and the roof can be perfect).

Make use of a high-quality battery. You get more for your money with newer batteries since they are more efficient.

Principal Advantages of Solar-Powered Air Conditioners:

Lower power costs

Eco-friendly energy

Minimal upkeep expenses

Possible advantages of net metering

dependable cooling (with battery) even during load shedding

The average cost is 4,300 × PKR 50, or PKR 215,000.

Battery and inverter = PKR 400,000–550,000

Note: Location, installation firm, and subsidies might affect prices.

Extra Advice Prior to Installation:

Verify the rooftop area (200–250 sq. ft. are needed for 11–13 panels).

For the most sunshine, make sure the panels face south.

To sell more electricity to WAPDA or your local grid, think about using net metering.

Reduce the need for panels by using an energy-efficient inverter air conditioner.

For a personalised quotation, speak with a certified solar installation.

Concluding Remarks:

In summary, daily use, panel efficiency, and whether someone uses battery backup all affect how many solar panels are needed for a 1.5 tonne air conditioner. To effectively run a 1.5-ton air conditioning system for eight hours a day, you’ll typically need 6 solar panels of 440 watts each.

In order to lower your electricity costs, this solar investment promotes cleaner and greener energy for a sustainable future.

FAQ’s:

How much solar panel is needed for 1.5 ton AC?

Six 440-watt solar panels often power a 1.5-ton air conditioner. A minimum of four to five batteries with a 150mAh cell capacity operate a one-ton air conditioner.

How many solar plates are required for 1.5 ton AC in Pakistan?

You will need 5 to 7 solar panels to power a 1.5-ton air conditioner in Pakistan, depending on the wattage of the panels you select. A 1.5-ton air conditioner uses approximately 1.5 to 2.0 kWh per hour, so you will need 6 to 7 panels if you are using 500-watt panels, and 5 to 6 panels if you are using 585-watt panels.

Can I run 1.5 ton AC on a 2kW solar system?

No, a 1.5-ton AC probably cannot be reliably operated by a 2kW solar system. 1.5 to 2 kW of power are usually used per hour by a 1.5-ton air conditioner. With a 2kW system, you might be able to run the air conditioner for a short while, but it probably wouldn’t be enough to power it for long, especially on sunny days or during peak hours.

How many solar panels do I need to run my AC?

At least 3 kW of solar panel output must be installed in order to operate a central air conditioning unit efficiently. It would take 30 panels to produce this 3 kW of power, as the majority of household solar panels produce about 100 watts.

Can I run a 1.5 ton AC on solar without batteries?

It is feasible to operate a 1.5-ton air conditioner without batteries using solar power, but doing so calls for a strong solar system and careful consideration of power needs. You’ll need a solar system that can reliably provide the 1.3 to 1.5 kW of electricity that a 1.5-ton air conditioner normally requires, even during times when there is less sunlight.

How Much Power Can A 10kW Solar System Generate?

With the rising cost of electricity and growing awareness about sustainability, many Australian homeowners are considering solar energy as a long-term investment.

Among the various system sizes available, a 10kW solar system stands out for its ability to generate significant power. But how much energy does it produce, and is it suitable for your household or business in Melbourne?

In this blog, we will explore the energy output of a 10kW solar system, the factors that influence its performance, and why the 10kW solar system Melbourne residents are choosing has become smart for economic and environmental reasons.

Understanding the Capacity of a 10kW Solar System

What Does 10kW Represent?

A 10kW (kilowatt) solar system refers to the peak capacity of the system to generate electricity under ideal sunlight conditions.

This means that when the sun is shining at its highest intensity, the system can produce 10,000 watts of electricity.

This size of system is typically suited for:

Large households with high energy usage

Properties with additional electrical loads, such as electric vehicles or swimming pools

Businesses with daytime energy consumption

Average Daily and Annual Output

A 10kW solar system Melbourne installation can generate approximately 35 to 45 kilowatt-hours (kWh) daily.

The exact output depends on several variables: location, roof orientation, panel efficiency, and weather conditions.

Annually, this equates to approximately:

12,775 kWh per year (at 35 kWh/day)

16,425 kWh per year (at 45 kWh/day)

The average Australian household consumes around 15 to 20 kWh per day, so a 10kW system can more than cover typical usage, offering opportunities to store or sell excess electricity back to the grid.

Why 10kW is a Strategic Choice in Melbourne

Favorable Sunlight Conditions

Melbourne receives an average of 4.0 to 4.5 peak sun hours per day, which supports consistent solar power generation.

This makes the 10kW solar system Melbourne homeowners prefer an efficient solution for offsetting energy bills and achieving energy independence.

Return on Investment

Although the upfront cost of a 10kW system ranges between $8,000 and $13,000 (before rebates), the potential savings are substantial.

Homeowners can expect to save approximately $3,000 to $4,000 annually on electricity, resulting in a typical payback period of 3 to 5 years.

Factors That Influence System Performance

Roof Orientation and Tilt

North-facing panels tend to yield the highest output in Australia. Roof pitch also plays a role in optimising sun exposure.

Shading and Obstructions

Trees, nearby buildings, or chimneys that cast shadows over panels can reduce system efficiency. Careful design and panel placement are essential.

Quality of Components

Higher quality solar panels and inverters are more efficient and durable, directly impacting the energy output and system lifespan.

Maintenance

Regular cleaning and occasional inspections help maintain system performance and prevent long-term efficiency losses.

System Requirements and Installation Space

A 10kW solar system typically requires 25 to 30 solar panels, depending on the wattage of each panel. This translates to approximately 40 to 50 square meters of roof space. It is essential to ensure that your roof can accommodate this size and that there is minimal shading.

Conclusion

10kW solar system Melbourne residents are investing in provides a reliable, efficient, and cost-effective way to meet high electricity demands.

With the ability to generate up to 45 kWh of electricity per day, such a system is well-suited for large homes and small businesses aiming to reduce energy costs and environmental impact.

When installed by a certified professional and maintained properly, a 10kW solar system offers long-term financial savings and contributes to a more sustainable future.

This system size delivers strong returns and energy security for years for those with the available roof space and energy needs.

If you are considering solar energy in Melbourne, exploring the benefits of a 10kW system is a step in the right direction.

Solar time!

A few years back, I was ready to pull the trigger on a home solar system - a 3 phase, 13.2kw unit.

Unfortunately, there was turmoil in my life, and I didn't end up going ahead with it - opting to do this after I had gotten a bit of stability in life. That time came in January 2025, and with that, I started looking at my options. The original installer I'd hit up a few years back had sadly gone into Administration, and weren't returning emails. In any case, I got a few quotes. I ended up going with an installer that was suggested by SolarQuotes, and going off my own googling, was fairly well regarded - ~4.4 stars out of 5, from ~450 reviews - so fairly well rounded. The appointment was booked in and they came. The day was a little grey with patches of rain, and the installers were onsite for 12 hours - significantly longer than the ~6-7 hours that was advised - at the time I figured, I'd rather them take their time and do it properly than rush it and do poorly. It ended up bucketing down in rain while they were working on the meter board, and out of an abundance of caution, I slept elsewhere. I get back the next morning, and I figure given their interesting approach to precautions around weather and electricity, I check the ceiling, and I'm greeted with...

And this quality of work was repeated across all the penetrations made. It was bad, and they should feel bad for it. I asked the installers to remediate this and a few other bits and pieces, which they did within a week. After that, I again, I popped my head up into the ceiling to check for leaks as it was raining, and while I had no leaks that I could see at the time, I was greeted with...

It just gets better and better... I ask the installers to get someone back out to fix, and that I wanted an independent report on the quality of the work. A team were out again the next week to resolve this, and I believe the report's being written up - which I will report back on. Let's get to the positives:

The system is installed working, and firing on all cylinders - it's a Sungrow SG-10RT 3P. I've got 30 TW Solar 440W panels - 20 on the NE side, and 10 on the NW side.

The meter upgrade is complete - I now have a 3-phase smart meter for all of my billing requirements.

It's Home Assistant friendly (by virtue of SunGather)

The installers did cable the unit in to my network as requested

It seems to performing splendidly!

Anywho, with most things wrapped up, I follow the instructions on the board and enable the DC side first, then the AC, and the unit springs to life - given it was around 6:30pm, I was generating a whole 10 watts! To integrate this with Home Assistant, I opted to use the SunGather Add-On. This seems to be a very capable add-on and so far works a treat, with the data being sent to HA via MQTT. For those reading, I did have to make some adjustments to the yaml file to get it going properly, and manually specified the serial number and the model number. I also set mine to level 3 data and have added more HA sensors.

The Sungather web page displays all the registers, values and outputs from those on a page - an example is below:

These, when fed into HA (via the Sungather YAML), show up as:

All in all, it's early days - with this being the first full day of operation/generation. I'm very much looking forward to adjusting my habits etc. to make the most of the system - it has a lot of potential, with the plan being to accomodate Ducted Air Con, a battery for storage, and an EV Charger at some point down the track.

How Much Electricity Does a 1000 Watt Solar Panel Produce Per Day?

Solar panel output is measured in kilowatt-hours (kWh). The basic formula for calculating daily power generation is:

Power Output (kWh) = Solar Panel Wattage × Sunlight Hours ÷ 1000

For example, if a 1000 watt solar panel receives 5 hours of full sunlight per day:

1000W × 5 hours ÷ 1000 = 5 kWh per day

This means a 1000 watt solar panel can generate 5 kWh of electricity per day under good sunlight conditions.

Example in Different Sunlight Conditions:Sunlight Hours Per DayDaily Power Output (kWh)4 hours4 kWh5 hours5 kWh6 hours6 kWh7 hours7 kWh

If you live in an area with high sunlight exposure, your solar panel will generate more power.

How Much Electricity Does a 1000 Watt Solar Panel Produce Per Month?

To calculate the monthly power output, use this formula:

Monthly Power Output = Daily Power Output × 30 days

Assuming 5 sunlight hours per day:

Investing in Solar Energy for Your Cambridge Home

Cambridge Solar energy is a renewable resource that can be used to produce electricity. It can also be used to heat and cool buildings. Solar panels can be installed on the roofs of homes and businesses.

The City is partnering with Boston-based EnergySage to leverage their online marketplace to offer transparent competition among pre-selected installers for the City’s residents. The program is called Sunny Cambridge.

Solar Panels

Solar panels are a great option for homeowners looking to save money on their energy bills and contribute to a cleaner, more sustainable world. It’s possible to recoup your installation costs in as few as 20 years with a 5 kW system, according to EnergySage.

MIT researchers have created an interactive tool to show Cambridge property owners how much electricity their roofs can generate via photovoltaic (PV) systems. The software can predict electricity yield to within 4-10 percent of actual measured results, and it takes into account variables such as roof size, type, and shading.

The following chart is a year-by-year breakdown of how energy is used, exported and imported with a solar PV system. The data was taken from a local install in a village north of Cambridge. The green line shows the amount of energy produced by the panels each day, with a peak around midday and then reducing as appliances are switched off at night.

Solar Panel Installation

Investing in a solar power system can save you money on electricity while supporting a sustainable future. Whether you're in an apartment, single-family home, or multifamily dwelling, there are many ways to go solar that suit your unique needs and goals.

During the day, sunlight hits your solar panels, which convert the energy into a direct current (DC) that powers your house. Any excess energy is sent to the grid, where it gets credited on your utility bill.

A 6 kW solar system costs about $17,220 in Cambridge before federal incentives. However, a 30% solar investment tax credit cuts that cost by thousands of dollars. Other state and local rebates can also lower your installation costs.

Solar Panel Costs

There are several factors that impact solar panel costs, including system size, roof type, and quality. Additionally, the cost of a battery can add up to your overall installation cost. But a battery allows you to store energy and use it at night, which can greatly decrease your electricity costs.

Typically, it takes 8 to 13 solar panels to cover a 2-3 bedroom home’s electricity needs in Cambridge. Once your system is installed, you can expect to save up to PS1,020 annually and benefit from the tax incentives available in Massachusetts.

The state offers various renewable energy incentives, including the 30% solar investment tax credit. This incentive reduces your cost per watt and is currently available through 2034. Also, the net metering policy offers credits to offset unused electricity from your solar system. These credits can be redeemed once your system has reached the break-even point.

Solar Panel Incentives

Taking advantage of local rebates and incentives will help you lower the cost of your solar panel system. Additionally, comparing multiple quotes will ensure that you are receiving the best price for your new system. Many companies also offer $0-down loans which can bring down the upfront costs even further.
