2.8.2. Solar thermal power production Solar energy can be converted into thermal energy by using solar thermal collectors which capture the radiation and transfer it to the fluid in the collector tubes. Fig. 2.9 shows the schematics of solar thermal power conversion (Kumar, Hasanuzzaman, & Rahim, 2019).
Schematics of solar thermal power conversion (Kumar et al., 2019). Nowadays, solar photovoltaic thermal is very popular technology where the solar thermal collector is integrated with PV panel and it gives more power output.
This is different from photovoltaic solar panels, which directly convert the sun’s radiation to electricity. What is Solar Thermal? Solar thermal generates energy indirectly by harnessing radiant energy from the sun to heat fluid, either to generate heat, or electricity.
Solar thermal energy (STE) is a form of energy and a technology for harnessing solar energy to generate thermal energy for use in industry, and in the residential and commercial sectors. Solar thermal collectors are classified by the United States Energy Information Administration as low-, medium-, or high-temperature collectors.
In solar thermal technologies, solar energy is converted into heat, which then can either be used for commercial or household heating and cooling (solar heating and cooling, SHC). For example, a very simple solar thermal system might heat water for use in a shower.
The basic scheme of a solar thermal energy installation is as follows: These are two closed circuits with a heat exchanger. In the primary circuit, the cold heat transfer fluid passes through the solar panels. Radiation from the Sun heats it and goes to a heat exchanger to transfer thermal energy to the secondary circuit and then, repeat the cycle.
