Hot air gun Valex P2000Article recommended to DIY photovoltaic modules
Some products called encapsulants, are not designed for the encapsulation of photovoltaic cells in that they contain fillers and are not weather-proof. The encapsulation of solar cells require materials with a stable thermal conductivity and UV filter, for a solar panel that lasts so, we recommend that you use only QSIL or EVA.
Most effective way to encapsulate your homemade solar module. This silicone is specially designed to encapsulate solar cells and electronics with a strong, transparent, non UV yellowing and reduce refraction, thereby increasing light transmission.
