A tile or plate, includes: an upper plate (3) and a lower plate (4); wherein a plurality of heat conducting cavities (6) are uniformly provided between the upper plate (3) and the lower plate (4) via connecting ribs (5). A solar collection layer is provided on an upper surface of the tile or the plate. Two ends of the tile or the plate are connected with each of the plurality of the heat conducting cavities (6) via transverse connecting pipes (23, 37, 42). The transverse connecting pipes (23, 37, 42) of two neighboring tiles are connected by a ferrule (17) or a hose (36) to form an integrated circulation system. The tile or plate has a large day-lighting area and a high energy conversion rate.

A building integrated thermal and photovoltaic cladding system includes: an exterior layer including photovoltaic elements, an interior layer including heat exchange modules; a load-bearing structure including one or more spacers configured to maintain the exterior layer in spaced apart relation to the interior layer, and providing an air flow conduit therebetween for receiving air from the exterior, the air flow generally passing over the interior layer by natural circulation.

The invention relates to enclosed solar parabolic trough reflector systems for thermal heat generation that can ultimately be used in various applications. The system includes a modular dual arch building design with a transparent building envelope and a reflector assembly connected within the building through a bearing assembly. The system is particularly suited for solar heat collection in harsh environment.

A hybrid-type solar panel comprising a structure suitable for making a photovoltaic panel, a thermal panel, a watertight roof, an electric storage, all integrated in a basic structure (20). A roof for a house is also provided.
