[0002] Photovoltaic tiles are crystalline silicon solar modules installed on tiles of synthetic materials. The crystalline silicon solar modules on the tiles are used to convert external light energy into electrical energy, achieving energy-saving and environmental protection effects. Photovoltaic tiles are installed on the roof structure like ordinary tiles. Photovoltaic tiles have better thermal insulation, heat preservation and power generation performance than traditional tiles.
