EVA encapsulation is the important element of a photo voltaic panel, safeguarding it from bodily injury and environmental adjustments. The EVA photo voltaic panel sheets act as a protecting barrier in opposition to moisture and air. A photo voltaic panel consists of various elements that enhance the working effectivity of photo voltaic cells. A great PV module has an EVA photo voltaic encapsulant sheet, backsheet, glass sheet, and protecting body.
The Ethylene Vinyl Acetate (EVA) sheet sandwiches the photo voltaic cell from above and beneath, making it sturdy and resistant to break. A powerful adhesive bond is shaped on the prime and backside of the cell, again sheet covers the photo voltaic cell that faces the mounting floor, providing further safety and stability.
Your choice to spend money on photo voltaic power is commendable. Whilst you assist the Inexperienced Earth initiative and assist in sustainable power progress, you additionally guarantee long-term financial savings in your power bills. Nonetheless, to safeguard this funding, understanding EVA photo voltaic panel encapsulation turns into crucial. EVA photo voltaic panel encapsulation isn’t just a preventative measure, however important for the longevity of your photo voltaic funding.
What’s EVA Photo voltaic Panels Encapsulation?
The Ethylene Vinyl Acetate movie is often used within the Photograph-Voltaic (PV) business. It’s a thermoplastic polymer movie with good radiation transmission capability, resists temperature fluctuations, and improves efficiency. Ethylene Vinyl Acetate (EVA) is a milky-white shade polymer having a rubbery texture. It’s most well-liked for photo voltaic cell encapsulation as a consequence of its sturdy adhesive, thermal stability, and age-resistance properties.
On heating the clear sheet even unfold throughout the cell appearing as an insulator for photo voltaic cells. The gases can not enter the cell and thus stop oxidation of the cell throughout its common functioning.
The EVA Photo voltaic encapsulants stop grime and humidity from penetrating the silicon wafer and act as a barrier. The silicon cells can simply transfer throughout the glass and photo voltaic again sheet. The cells can stand up to thermal shocks, and vibrations thus defending {the electrical} unit from injury.
Key Options of Photo voltaic Encapsulants
- Optical Transmission: Maintains power output by stopping mud blockage.
- Warmth Resistance: Protects cells from temperature adjustments.
- Mechanical Energy: Helps cells beneath fixed stress, growing lifespan.
- Prevents Oxidation: Resists corrosion, preserving energy era.
- Electrical Insulation: Safeguards in opposition to electrical faults and lightning.
- Sturdy Adhesion: Bonds firmly with glass/backsheets for panel integrity.
These options guarantee photo voltaic panels stay environment friendly and sturdy, maximizing their efficiency and longevity in numerous environmental circumstances.
Benefits of EVA photo voltaic encapsulants and defending your photo voltaic funding
The function of EVA sheets in photo voltaic panels is just like the smartphone display screen guard which protects the delicate contact display screen from injury or scratches and retains it operating easily. There are quite a few advantages of utilizing EVA photo voltaic encapsulant sheets:
#1 Most publicity for higher daylight transmission:
The EVA sheets are most well-liked for his or her most radiation transmission capability. Daylight can simply cross via the EVA sheet, permitting the photo voltaic cell to soak up most photo voltaic power. In the meantime, the sheets defend the panel from mechanical stress at excessive temperatures. It’s higher to place photo voltaic panels in a course that permits most daylight publicity.
#2 Low degradability price for longevity:
The EVA sheet protects the photo voltaic panel from exterior environmental adjustments, grime, mud, wind, and moisture. The whole photo voltaic encapsulant acts as a protecting layer in opposition to water, humidity, and leakage. All these elements degrade the photo voltaic cell’s working effectivity and require common restore and upkeep.
#3 Compact encapsulation:
The lamination course of encapsulates the crystalline silicon cell with the EVA sheet. It creates an adhesive bond with TPT (Tedlar-PET-Tedlar composite movie) because the decrease protecting layer near the photo voltaic again sheet and glass because the higher protecting layer. The entire construction turns into sturdy and features energy to work in hostile climates.
#4 Minimal Shrinkage for Photo voltaic Cells:
Minimal shrinkage happens in the course of the lamination of EVA sheets over the photo voltaic cells, holding the photo voltaic module design intact. Since photo voltaic cells are delicate, a excessive shrinkage price can injury the cell unit or trigger leakage. A strong photo voltaic encapsulant unit permits higher power absorption and protects the cell from exterior stress.

#5 Safety from harsh UV rays:
UV rays injury the photo voltaic cells. We require EVA sheets which are immune to UV rays and don’t disrupt the photo voltaic panel working. Earlier thermoplastic EVA sheets used for encapsulation lacked UV safety however with expertise development now we provide EVA sheets that provide UV resistance. The glass layer offers further security.
#6 Stand up to in opposition to huge temperature:
The EVA sheets can transmit 90% of sunshine and supply resistance at excessive temperatures of 85°C and low temperatures of – 40°C. The EVA photo voltaic panel has nice stability and minimal thermal enlargement and contraction of cells. It prevents the getting older and cracking of photo voltaic cells, offering efficient energy era.
Utility of Photo voltaic Encapsulant on PV Modules
The photo voltaic EVA movie market is anticipated to achieve $6.9 billion by 2032, exhibiting a CAGR of 11.58% in the course of the forecast interval from 2021 to 2032.
Within the photo voltaic business, cross-linkable ethylene vinyl acetate movies are used for photo voltaic cell encapsulation. These EVA adhesive sheets are made from thermoplastic glue that will get mushy on heating and solidifies on cooling, offering a robust cohesion between the 2 supplies.
Utilizing a lamination machine, EVA sheets laminate the highest and backside of the photo voltaic cell beneath compression in a vacuum. The entire course of occurs at a excessive temperature of 150°C. The EVS sheet acts as a layer of safety and restricts grime, mud, or water from coming into the cell. The photo voltaic encapsulant gives lengthy sturdiness and high-power output.
Anti-ultraviolet brokers, antioxidants, and curing chemical compounds are generally integrated into an EVA movie that usually ranges in thickness from 0.4 to 0.6 mm. (380 to 600 GSM). These parts play an important function within the sealing and bonding between the EVA sheet, glass, and again sheet.
