Technology is always fascinating. While looking at the roofs, have you wondered what’s inside the solar panels? Solar panels are composed of solar cells made of the element – silicon. They are delicate and prone to harm. So, what makes them work so well, even on scorching days or under harsh rains? EVA sheets are an essential solar panel component. In this blog, we will understand the crucial role of EVA sheets in commercial solar panels. Read to know more about the uses of high-quality EVA sheets.
Ethylene Vinyl Acetate, aka EVA, is a thermoplastic sheet coated on solar panels to protect it from harsh sun rays. It encapsulates the solar cells between the back plate and protective glass. The EVA sheets are transparent and adhesive. The transparency allows the sunlight to pass through the solar cells, and the adhesive ensures it sticks to the glass and keeps the solar cells intact. Commercial solar panels used in big plants or rough environments need protection for their longevity. EVA sheets act like a barrier to encapsulate solar cells and hold the solar panel components in place. The EVA sheets are even more crucial in commercial solar panels because of their protective and supportive functions. Over the years, there has been significant improvement in commercial solar panels, thanks to the high-quality EVA sheets.
There are numerous EVA sheets, ranging from their performance and lifespan. So, let’s examine why high-quality EVA sheets are important in manufacturing commercial solar panels.
The solar cells are delicate as they are made of silicon crystals. It is often at risk if kept open in the solar panel. The environment’s dirt, water, and humidity can hinder their performance. In the worst-case scenario, it can cause permanent damage to the solar cells. Therefore, high-quality EVA sheets encapsulate the solar cells in a compact arrangement before sealing them between the back sheet and glass. The EVA sheet allows no air, dirt, or water to pass. Commercial panels are often placed in harsh environments. Be it on the rooftop with maximum exposure to dirt, air, water, and humidity or on the open ground, which is more prone to physical damage than dirt and water. So, the high-quality EVA sheets work like a protective barrier for the solar cell.
