Please note that this product is assembled by hand. Before assembly, we put a protective film on the solar panel, so that there may be scratches on the film and the solar panel. The scratches will not affect the performance of this product. Unlike most other solar garden products, the material on their solar panel becomes white or cloudy within a year. To prevent this problem, we put a special material on our solar panel although not scratch resistant but it will last up to 3 to 4 year.
