摘要

The panel has a frame (1) that is made of aluminum, and joints (3) made of rubber, where the panel is manufactured with a natural cork oak insulation (4). Blades (7) are fixed on a rectangular- or square-shaped coil tube (6). The tube is made of stainless steel and is welded on a black stainless steel plate (5). The blades receive solar energy in morning and evening times, where the solar energy is transmitted to water.
