Be provided with back-up block between described second solar panel and reflective membrane, described back-up block is between adjacent cell sheet.
The material of described respiratory membrane is expanded PTFE.
Described cell piece is corner light-permeable cell piece.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model arranges loophole on glass outer, cell piece on second solar panel of such backlight can accept through loophole and the sunlight of reflection through reflectance coating, guarantee tile install time backlight solar panel still can normal power generation, also reduce the impaired probability of battery component simultaneously, extend its useful life, substantially increase the cost performance of battery component.
2, in the utility model, the respiratory membrane at loophole aperture place has also stopped the possibility that rainwater dust enters while ensure that printing opacity, ensure that the stability of battery component.
3, the cell piece in the utility model can increase light transmittance due to its corner, and compared with the polycrystalline cell piece of same efficiency, its glazed area can increase by 2.83%.
