Abstract
The utility model discloses a novel insulation back panel for a solar photovoltaic battery, which comprises a structure enhancement layer, a bonding layer, a weather-resistant layer and an E bonding layer, wherein the weather-resistant layer is compounded on the surface of one side of the bonding layer back to the structure enhancement layer in hot compounding mode, and the E bonding layer is directly combined on the surface of the other side of the structure enhancement layer. The novel insulation back panel for the solar photovoltaic battery has the advantages that the E bonding layer is directly compounded with the structure enhancement layer in hot compounding mode with no need for adhesives, the E bonding layer is good in combining performance and can be directly compounded with the structure enhancement layer in film-making, and therefore cost is effectively reduced and capacity is increased.
