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.

What is an EVA Sheet?

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.

Importance of Top-Grade 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.

1. To protect the solar cells

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.

2. To increase the durability of solar panel

Solar cells are the powerhouse of solar panels. Any damage to the cell will result in loss of lifespan and performance. So, the durability of the solar panel depends on solar cells. The EVA sheets ensure the solar cells’ safety for long-term performance. It increases the durability of the commercial solar panel, resulting in better ROI.

3. To decrease the degradation rate of solar panel

The EVA sheets work as a protective layer and repel UV rays. The UV rays can damage the solar cells and their performance, resulting in quick degradation. The high-quality EVA sheets protect the solar cells from UV exposure and reduce the degradation of solar cells, resulting in a longer solar panel life span. Additionally, it results in consistent performance even on hot days with more sunlight exposure.

4. To boost temperature resilience

We all know that solar panels work on sunlight. We also know that too much of anything can be harmful. So, in case of excessive sunlight, the solar panel gets overheated, affecting its overall performance and potentially damaging it. The EVA sheets are a barrier to managing the solar panel’s temperature.

5. To enhance the structural integrity of solar panel

Solar panel components work in synergy for optimum performance. The solar cells connected and protected by the glass and back sheet are the most crucial. Therefore, high-quality EVA sheets have become a must to bind these three together. The adhesives in the EVA sheets allow us to connect these three solar panel components in place. Therefore, it offers structural integrity to the whole solar panel unit.

6. To increase the sunlight exposure

Optimum sunlight exposure is crucial for better performance. So, high-quality EVA sheets will enable us to maximize sunlight exposure while protecting the solar cells from humidity, dirt, and water. The EVA sheets are made of transparent thermoplastic that allows sunlight transmission.
