The solar collector subsystem in SPT mainly consists of the solar heliostats field, the tower, and the solar receiver [81], as shown in Fig. 29. The solar radiation is concentrated by numerous heliostats and reflected onto the receiver where the heat transfer fluid (HTF) is heated up to a relatively high temperature.
Solar explained Solar thermal collectors
Non-concentrating and concentrating solar collectors. Non-concentrating solar collectors. Solar energy systems that heat water or air in buildings usually have non-concentrating collectors, which means the area that intercepts solar radiation is the same as the area absorbing solar energy.Flat-plate collectors are the most common type of non …
