Key Features of Solar Encapsulants

Optical transmission
A core feature, the encapsulants prevent dust and debris from halting the light transmission to the solar cells and therefore helps maintain the energy output
Heat Resistance
Extreme thermal fluctuations can affect normal performance of solar cells. Encapsulants help solar cells bear the changes in temperature by forming a protective layer around them.
Mechanical Strength
Solar encapsulants provide direct support to solar cells that are subjected to constant mechanical stress. It enhances their endurance and increases their lifespans.
Prevents Oxidation
Oxidation due to moisture can erode solar cells’ power generation capacity. With corrosion resistance abilities, encapsulants prevent the solar cells from oxidation.
Electric Insulation
Insulation properties of encapsulants safeguard against damage caused by electrical faults or lightning strikes, effectively preventing short circuits.
Strong Adhesion
An important property of our encapsulants is their strong bonding abilities with solar glass/backsheets that makes the panel full-proof

Role of Solar Encapsulants in Solar Panels

Solar encapsulants play a vital role in protecting and preserving the efficiency of solar cells. These encapsulants have multifaceted contributions to solar PV installations as they form the indispensable layer of protection for solar cells.

FAQs Regarding Solar Encapsulants

What is EVA encapsulant in solar?
The EVA (ethylene-vinyl acetate) encapsulant is a protective layer that shields solar cells. It’s a copolymer resin that protects PV cells from jerks, shocks, moisture, excessive heat, UV rays, electric short circuits, and stress.
What is encapsulant in a solar panel?
Encapsulant is a polymer that creates a protective layer around the solar cell by adhesion with solar glass/backsheet. It safeguards against moisture, mechanical stress, debris, corrosion, thermal fluctuations etc. ensuring the durability and performance of the solar panel.
Why are solar panels encapsulated?
Solar panels undergo encapsulation to provide necessary protection and support to the delicate solar PV cells. This process enables the panels to withstand environmental challenges and mechanical stress to the structure.
What are the methods of solar panel encapsulation?
Solar panel encapsulation can be accomplished through various methods, with lamination being the most prevalent. In the lamination process, solar cells are enclosed between layers of encapsulant and protective materials, resulting in a sealed and durable unit.
What is the process of EVA encapsulation?
The EVA encapsulation procedure involves inserting a layer of ethylene-vinyl acetate (EVA) between the solar cells and the protective glass or backsheet. This EVA layer is then heated and compressed to produce a strong, transparent, and weather-resistant seal that safeguards the solar cells from environmental factors and physical strain.
