Eva For Silicon Solar Panels

Solar eva sheets play an important part in enhancing the durability and performance of solar panels.

Eva for silicon solar panels.

Like conventional solar panels amorphous solar panels are made from silicon but they are constructed in a different way. Without silver involved solar panels could not be as efficient in turning sunlight into usable energy. So it is somewhat ironic yet also fitting that silver helps us retrieve power from the same kind of energy source from where it was initially born. We have solar panels for homes commercial system solar panels as well as complete lines of both small solar panels and large solar panels.

There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used. All assembled in a tough aluminium frame. Manufactured at one of asia s largest ethylene production facilities the high performance eva sheets we supply are subject to. The choice of eva encapsulant used in the manufacturing of solar pv panels significantly influences the end product s lifespan and its susceptibility to defects and eventually the yield of the whole solar pv system in which the solar pv panels are used.

Although slightly more expensive the beauty of glass it will not degrade. None the less the over whelming majority of solar panels are comprised with an eva back sheet due to affordability. Ethylene vinyl acetate eva also known as poly ethylene vinyl acetate peva is the copolymer of ethylene and vinyl acetate the weight percent of vinyl acetate usually varies from 10 to 40 with the remainder being ethylene. Instead of being constructed from solid silicon wafers like mono or poly crystalline solar panels amorphous panels are made by depositing non crystalline silicon on a substrate like glass plastic or metal one layer of silicon on an amorphous solar panel can be as thin.

They enable the solar cells to float between the glass and the backsheet helping to soften shocks and vibrations and protecting the cells and their circuits. Once the eva sheets have been laminated the ethylene vinyl acetate sheets play an important role in preventing humidity and dirt penetrating the solar panels. Sealing my solar cells with 0 3mm solar grade eva and a home vacuum cleaner. We explain how silicon crystalline solar cells are manufactured from silica sand and assembled to create a common solar panel made up of 6 main components silicon pv cells toughened glass eva film layers protective back sheet junction box with connection cables.

Glass glass or double glass solar panels available from selected manufacturers utilise a rear glass protective sheet in place of an eva.
