Global Top 5 Companies Accounted for 85% of total PV Modules market (QYResearch, 2021）

An encapsulant is used to provide adhesion between the solar cells, the top surface and the rear surface of the PV module. The encapsulant should be stable at elevated temperatures and high UV exposure. It should also be optically transparent and should have a low thermal resistance. EVA (ethyl vinyl acetate) is the most commonly used encapsulant material. EVA comes in thin sheets which are inserted between the solar cells and the top surface and the rear surface. This sandwich is then heated to 150 °C to polymerize the EVA and bond the module together.

Encapsulant materials used in photovoltaic (PV) modules serve multiple purposes; it provides optical coupling of PV cells and protection against environmental stress. Polymers must perform these functions under prolonged periods of high temperature, humidity, and UV radiation. When PV panels were first developed in the 1960s and the 1970s, the dominant encapsulants were based on polydimethyl siloxane (PDMS). Ethylene-co-vinyl acetate (EVA) is currently the dominant encapsulant chosen for PV applications, not because it has the best combination of properties, but because it is an economical option with an established history of acceptable durability. Getting new products onto the market is challenging because there is no room for dramatic improvements, and one must balance the initial cost and performance with the unknowns of long-term service life. Recently, there has been renewed interest in using alternative encapsulant materials with some significant manufacturers switching from EVA to polyolefin elastomer-based (POE) alternatives.

According to the new market research report “Global PV Modules Market Report 2023-2029”, published by QYResearch, the global PV Modules market size is projected to reach USD 7.38 billion by 2029, at a CAGR of 11.2% during the forecast period.

What are the Key Components of Solar Panels?

A conventional components of solar panels, including a layer of silicon cells, a sturdy metal frame, a protective glass enclosure, and a network of interconnected wiring that facilitates the smooth flow of electric current generated by the silicon cells. Silicon, despite being a nonmetallic element, possesses remarkable conductive properties, allowing it to capture and convert sunlight into electrical energy. This remarkable phenomenon is attributed to the “photovoltaic effect,” which serves as the fundamental principle underpinning solar panel technology.

In essence, when sunlight strikes a silicon cell, it triggers the movement of electrons within the cell, setting in motion an electric current. This process enables the solar panel to harness the sun’s radiant energy and transform it into a readily usable form of electricity. Remarkably, this energy generation continues as long as the sun is shining, making solar panels a dependable and sustainable source of power. Furthermore, even on overcast days when sunlight is diffused by cloud cover, solar panels are still capable of generating electricity, thanks to the sun’s persistent ability to penetrate the cloud layers. A few years ago, coal, wood, and biomass were the primary sources of energy, while renewable energy played a secondary role. However, today, renewable energy sources such as solar energy, hydroelectric power, and wind power have replaced traditional sources. Solar energy, in particular, stands out as a cost-free and environmentally friendly energy source harnessed from sunlight. Solar photovoltaic (PV) modules, commonly known as solar panels, play a pivotal role in converting sunlight into electricity during daylight hours. In this comprehensive article, we will delve into the solar panel parts and components. In a subsequent piece, we will explore the installation process of solar panels.

Solar Panel Parts And Components

A solar PV module, or solar panel, is a complex assembly comprising nine essential components of solar panels, each of which plays a crucial role. Let’s explore these components one by one:

Solar Cells: At the core of every solar panel lie solar cells, which serve as the fundamental building blocks. Thousands of these cells are meticulously connected to form a solar panel. The assembly process involves soldering, encapsulation, mounting on a sturdy metal frame, and thorough testing. The efficiency of a solar panel is directly linked to the efficiency of its solar cells. Both the cost and performance of these solar cells significantly influence the overall effectiveness of the panel. Notably, solar cell efficiencies have steadily improved over the past decade. Various materials used in their production yield differing efficiencies. Even within the same technology, different companies may achieve varying conversion efficiencies. Two common types of solar cells are monocrystalline and polycrystalline solar cells.

Solar Glass: Another critical solar installation components is the solar glass, which serves as the outermost layer of the solar panel. This glass must possess both strength and reflectivity for optimal panel performance. Its primary function is to shield the solar cells from adverse weather conditions, dust, and dirt. Typically, tempered glass with a thickness ranging from 3mm to 4mm is recommended.

EVA (Ethylene Vinyl Acetate): EVA is a highly transparent plastic layer used to encapsulate the solar cells. It forms a protective, laminated coating atop the cells, holding them together securely. This material must exhibit durability and tolerance to withstand extreme temperature and humidity conditions.

Back Sheet: The back sheet, located at the rear of the panel, serves a dual purpose by providing mechanical protection and electrical insulation. It essentially serves as a protective covering.

Aluminum Frame: The aluminum frame is a critical structural pv panel component that imparts strength to the solar panel. It is advisable to use a frame constructed from a strong yet lightweight solar panel raw material. The frame should be rigid and capable of withstanding harsh environmental conditions, including high winds and external forces. Typically, aluminum frames come in two varieties: silver and anodized black.

Junction Box: Positioned at the rear of the panel, the junction box serves as the central point where cables interconnect with the solar panel.

Interconnectors: Interconnectors facilitate the connection of solar panels to one another. These solar panel parts must exhibit exceptional weather resistance while enabling secure connections.

Silicon Glue: Silicon glue stands as the most commonly employed adhesive within a solar panel. Its robust bonding properties, along with resistance to chemicals, moisture, and adverse weather conditions, make it the preferred choice for affixing components. Notably, silicon is also the predominant semiconductor material.

Inverter: After the solar panels capture DC electricity, the next step is to channel it through a solar inverter. Your home’s grid and appliances operate on alternating current (AC) electricity. Consequently, the inverter plays a crucial role in transforming the DC electricity harvested from your panels into AC electricity, making it usable. There are two prevalent types of inverters: string inverters and microinverters. String inverters are typically affixed to the side of your residence, where they consolidate all the electricity generated by your solar system. On the other hand, microinverters are compact devices attached to the underside of each individual solar panel, allowing for the direct conversion of DC to AC power at the panel level. At GST, we offer both inverter systems. To determine which inverter system best suits your needs, we recommend consulting with your solar adviser for more information.

Conclusion

Investing in a solar panel system constitutes a significant financial commitment. Therefore, it is advisable to prioritize high-quality solar plant components. Most solar panels come with a 25-year warranty, underscoring the importance of assessing the quality and understanding the function of each constituent part. Prospective buyers should equip themselves with knowledge about the various solar panel parts and components involved in solar panel fabrication, their roles, and overall functionality to make informed decisions and avoid substandard components.

Solar Panels With Photovoltaic Technology: A Step-By-Step Guide

Photovoltaic solar panels are becoming more and more prevalent in our daily lives. The energy transition encourages the use of alternative energy sources that help reduce carbon emissions.

Photovoltaic solar panel service also have a wide range of applications, both at home and in industry.

In this post, we’ll cover all you need to know about solar panels, with a particular emphasis on self-consumption modules.

What are solar panels and how do they work?

Solar panels may appear to be difficult to operate.

But is it really?

Solar panels are nothing more than photovoltaic cells with the sole purpose of converting solar energy into electrical energy.

The process is as follows: photovoltaic cells catch photons from the sun and convert them to electrons owing to the semiconductor material they are comprised of, silicon.

Because the current generated by the solar panels is continuous, it must be converted to alternating current using a solar panel inverter , as alternating current accounts for the majority of the energy utilized on a daily basis.

What are the components of a solar panel?

Solar panels are made up of the following components in addition to photovoltaic cells:

The electrical link that connects cells.

EVA — ethylene vinyl acetate — is commonly used as an encapsulant. Around the solar panels, this produces a sealing layer. It is crucial because it safeguards the photovoltaic cells.

The solar cells are protected by tempered glass or glass, which is used in conjunction with the encapsulant.

On the back of the solar panels, there is a PVC sticker.

Fixing hole in an aluminum frame.

A photovoltaic system includes the framework where the modules are installed, the wiring, the inverter that converts direct current into alternating power, and, if necessary, solar panel battery . as well as energy meters

What is the process of making solar panels?

A solar panel is made through a lengthy procedure that is carried out by professionals.

First and foremost, 98 percent pure silicon must be produced from bits of quartz stones extracted from a mineral vein. This product is 98 percent pure.

The purity of silicon is critical for solar panels to work well. Chemical processes such as washing and pickling are used to purify it.

Crystal development begins once the silicon is melted. Monomolecular layers are formed around a seed of crystallization or an initial crystallite.

The crystallization seed forms into a crystalline form, a monocrystal, or a polycrystal, depending on its size.

This technique is carried out at a temperature of over 1500 °C. We will obtain an ingot shape by treating the silicon in this manner.

The electrical conductors are added when the ingot is sliced into thin sheets.

Surface imperfections and cut flaws may occur after the wafers have been cut. The next step is to ensure that these flaws are corrected.

Finally, some metal strips embedded in the surface are connected to electrical contacts, which absorb and transmit electrical energy.

Types of photovoltaic solar panels

We discussed monocrystalline and polycrystalline cells in the preceding section. These factors have an impact on the type of solar panel used.

Photovoltaic solar panels are divided into three categories:

Monocrystalline

polycrystalline

amorphous

Monocrystalline photovoltaic solar panels are the finest grade of the three varieties of photovoltaic solar panels. These are made up of cells that are made up of a single silicon crystal, resulting in higher efficiency.

What are the raw materials of photovoltaic modules

Although the composition of photovoltaic power generation systems varies in materials, all components include several layers of materials from the light-facing side to the back-lighting side. Sunlight first passes through a protective layer (usually glass) and then enters the interior of the cell through a transparent contact layer. At the center of the module is an adsorbent material, a layer of material that absorbs photons to complete the "photoelectric current". Among them, the semiconductor materials depend on the specific requirements of the photovoltaic system. The raw materials of photovoltaic modules are composed of eight main materials and auxiliary materials for production.

1. Cell: A solar cell is a device that converts light energy directly into electrical energy. It is made of semiconductor material. Through the irradiation of sunlight, the electron-hole pairs are excited, and the electrostatic field in the PN junction barrier region is used to separate the electron-hole pairs. The separated electrons and holes are collected and exported to the outside of the battery through the electrodes to form a current. .

2. Tin-coated copper strip: It is cut and straightened by oxygen-free copper, and all outer surfaces have hot-dip coating. Tin-coated strips are used to lead out the electrodes of solar cells and connect cells during the production of solar photovoltaic modules. High welding operability, firmness and flexibility are required.

3. EVA: A copolymer of ethylene and vinyl acetate, a hot-melt adhesive. It is used to encapsulate the battery, prevent the external environment from affecting the electrical performance of the battery, enhance the light transmittance of the photovoltaic module, and bond the battery, tempered glass, and backplane together to have a certain bonding strength. The electrical performance output of the component has a gain effect.

4. Back sheet: used as back protection packaging material, commonly used is divided into T door, TPE and PET, polyethylene structure. It is used to enhance the aging resistance and corrosion resistance of photovoltaic modules, prolonging the service life of photovoltaic modules; High infrared emissivity, can also reduce the operating temperature of photovoltaic modules; at the same time improve the insulation performance of photovoltaic modules.

5. Tempered glass: It is used to support the structure of photovoltaic modules, enhance the load-bearing and load of photovoltaic modules, and has the functions of light transmission, anti-reflection light transmission, water resistance, gas resistance and corrosion resistance.

6. Aluminum frame: The aluminum alloy frame installed on the glass extension can protect the edge of the glass, strengthen the sealing performance of the photovoltaic module and improve the overall mechanical strength of the photovoltaic module, which is convenient for the installation and transportation of the photovoltaic module.

7. Silica gel: used for bonding and sealing laminated glass photovoltaic modules, bonding junction boxes and backplanes, and enhancing the UV resistance of photovoltaic modules.

8. Junction box: The electrical connection device of photovoltaic modules, which can seal and waterproof the lead-out wires of photovoltaic modules and protect the safety of photovoltaic module systems during operation.

As a terminal product of the photovoltaic industry, photovoltaic modules are closely integrated with the market. The products will be directly oriented to customers. There are many kinds of raw materials used. The selection of different photovoltaic materials will directly affect the relevant performance of the modules. In addition, encapsulation can avoid battery fragmentation and facilitate outdoor installation. The quality of encapsulation determines the service life and reliability of solar cell components.

Effect of EVA Material Aging on Photovoltaic Modules

Effect of EVA Material Aging on Photovoltaic Modules

The EVA film has a strong adsorption capacity. During use, pay attention to moisture and dust, and avoid contact with coloured objects.

Do not expose the entire roll of film with its outer packaging removed to the air. If the film that has been cut into slices cannot be used up on the same day, it should be covered tightly. The storage environment is where the temperature is below 30 degrees and the humidity is below 60%.

1. Fading

During the operation of photovoltaic modules, EVA will undergo "yellowing" and "browning" when exposed to the outdoor environment for a long time.

2. Layering

The degradation of EVA leads to a decrease in adhesion and delamination, which causes the loss of adhesion between the cover glass and the solar cell and/or between the solar cell and the back sheet material.

3. Blistering

Blistering is a process similar to delamination, which is caused by the lack of adhesion of EVA and affects a smaller area. Bubbles are created as a result of chemical reactions that release gases that typically appear at the rear of the module and collect in the encapsulation, but occasionally at the front between the glass and the cell.

How EVA anti-aging

They add inorganic particles, antioxidants, light stabilizers and other additives to EVA materials to reduce the oxidative decomposition rate of EVA, or use organic oxides, etc., to alleviate the ageing problem of the photovoltaic film.

In addition, scientists have also discovered that rare earth complexes can absorb ultraviolet light and convert visible light, organic complexes of rare earth materials are dispersed into EVA materials through physical mixing, and EVA light-converting films are coated on the surface of polysilicon solar energy. Rare earth materials act as a transit station for ultraviolet rays, which can improve the photoelectric conversion rate of polycrystalline silicon solar cells.

Solar energy has become an important part of human energy use and is constantly being developed. FGNEX SOALR conducts more research on solar cells, which can help people make better use of solar energy and take a step forward to new energy.
