Panel comprises transparent or translucent front panel (3), back panel (5), air permeable heat absorber (4) and air outlet (6) extending from volume (8) enclosed by the front panel and heat absorber to a common ventilation duct. Photovoltaic cell panels are arranged between the front panel and the heat absorber. The back panel is a 0.4 - 4mm thick perforated aluminum plate, the back panel IR radiation reflection coefficient is 0.8 - 1, the heat absorber is a 0.4 - 4mm thick aluminum plate with an opening of 0.7 - 3mm spaced 8-20mm apart or a fibrous mat such as a screen of felt and the side facing the front panel has an absorption coefficient of 0.8 - 1. There is an Independent claim for a ventilation system. |
