Abstract: The presented solar collector panel based on direct solar absorption, offers significantly higher efficiency over the traditional tube and fins designs. This is achieved by containing the heat exchanging fluid under the whole area of the absorber, this reducing its temperature, the main condition for the high efficiency. The heat exchange is further improved by increasing the heat dissipation area. Meandering channel design ensures uniform temperature distribution, which also improves efficiency. In addition to the patent claims, a system with individual panel control is described, taking advantage of different roof slopes and sun movement throughout the day.
