The utility model relates to a novel solar battery rear panel which comprises a substrate, an upper weather-proof layer and a lower weather-proof layer, wherein the upper weather-proof layer and the lower weather-proof layer are respectively combined with the substrate by a casting compounding form into an integral laminated structure; each of the upper weather-proof layer and the lower weather-proof layer comprises a base layer, a function layer and a binding layer; and the upper weather-proof layer and the lower weather-proof layer are respectively connected with the substrate by the binding layers. In the utility model, the binding layer is a modified polyethylene layer or an ethyl vinyl acetate layer, thus the binding property of the binding layer and the solar battery rear panel substrate is better compared with a polyvinylidene fluoride film used by the conventional solar battery rear panel; the function layer is a polyvinylidene fluoride layer and is placed at the outermost side of the solar battery re
