Introduction to Solar Tempered Glass
Solar tempered glass is a crucial component in the solar energy industry. It is designed to protect the solar cells in photovoltaic (PV) panels from various environmental factors such as hail, wind, and UV radiation. The tempering process enhances the glass’s strength, making it more resistant to breakage compared to regular glass. It also has high light transmittance, which allows maximum sunlight to reach the solar cells, thereby improving the efficiency of the PV panels. Additionally, solar tempered glass is usually coated with anti – reflective and self – cleaning properties to further optimize the performance of solar panels. Solar Tempered Glass
