Therefore, the operation temperature range is from ca. ambient to up to 85 °C fluid temperature. Advantages of this PVT design toward a classic solar thermal collector are to provide electric energy from the same area using factor surplus to direct useable graded heat at hot water and heating support temperature levels.
The Solar thermal collector can use spectrum in the long-wavelength part of the spectrum up to the infrared region, while photo-voltaic systems can efficiently utilize the solar energy spectrum of visible light towards a small wavelength up to the ultraviolet region [81,127] ).
Hence, PhotoVoltaic/Thermal (PVT) hybrid solar collector was suggested as a solution for promoting the PV efficiency and the benefit of solar radiation. It is incorporation of solar PV with the STC that serves in the simultaneous generation of electricity and heat with half the area needed and little extra cost.
The evaporator section was in the shape of sunflowers to fully absorb sunlight, and the condenser section was distributed in a cold-water tube. The results indicated that the thermal efficiency of solar collector could reach 50% when the filling ratio was 50%. Fig. 40.
On the contrary to solar thermal collectors with selective absorber coating, the heat losses due to infrared radiation emission on the front side of the covered PVT panel limit the thermal efficiency in the upper-temperature range, if no engineering measures are taken.
