The thermal efficiency of the EFPCs reaches a maximum value of 73.2%, with the glycol–water mixture as a heat transfer fluid at an inlet temperature of 31.2 °C, when the ambient temperature is 15.3 °C, average irradiance is 679.2 Wm −2 , and vacuum pressure is 20...

...-up solar field using the CL strategy allows us both operational autonomy and significant energy savings. Solar loop thermal and optical powers gained and lost are plotted for the typical days considered; we observe that maximum thermal efficiency of 66.53% is achieved at 2.27 p.m. for the summer day...

..., while the quartz half-shell temperatures exceed 800 °C. The combination of both phenomena results in higher advective losses for the half coverage, T 0 = 500 K case and similar advective losses for the half coverage, T 0 = 873 K case compared to the no coverage cases. Thermal efficiency...

The outlet hot air temperature from the heater and its thermal efficiency are compared for different mass flowrates and solar radiations. Also the temperature distributions in the jet plate with the jet configurations...

...) and serves to rise its temperature (41–46 °C) and the thermal efficiency (23–28%). We can deduce that it is better to keep a low emissivity of about 0.14 to prevent heat dissipations.
