Abstract: A solar roofing panel system for use in residential and commercial buildings employing conventional metal roofing components. The system collects and supplies thermal energy from the sun to heat the interior thereof and also is capable of providing solar generated electricity for powering the normal complement of household appliances. The system can also be adapted to provide a thermal energy source for absorption cooling for commercial applications such as supermarkets or the like. The system employs an air-to-liquid system in the preferred embodiment. The alternative embodiment has an air-to-air heat exchange system.
