Parabolic troughs, which are a type of linear concentrator, are the most mature csp technology with over 500 megawatts mw operating worldwide. Parabolictrough solar collectors and their applications. Design, construction and testing of a parabolic solar. Different types of solar collectors are studied, as well as the solar resources in the area. The parabolic trough collector ptc is the most common type of hightemperature solar thermal technology, in which the heat transfer fluid is usually synthetic oil, molten salt or watersteam. In this case, a parabolic mirror concentrates incident solar irradiation onto a much smaller receiver area, greatly decreasing heat loss and maximizing the available energy from the sun. Although the sun is 150 million kilometres away it is still extremely powerful. Performance analysis of parabolic solar dish collector for. The photons comprising the solar radiation can be converted directly to electricity in photovoltaic devices, or, in concentrating solar power csp.
