Experimental studies on passive inclined solar panel absorber solar still

This manuscript aims to analyze the passive inclined solar panel basin (PISPB) still at diversified flow rate of water (m(f)). The freshwater collected from the solar still for different m(f) at 4.68, 7.56 and 10.08 kg h(-1) is 3.7, 2.7 and 1.6 kg, respectively. Results showed that at higher flow condition, the still energy and exergy efficiency decreases and it is estimated as 36.06, 25.56 and 16.95% and 2.97, 1.91 and 1.01%, respectively, for flow rates of 4.68, 7.56 and 10.08 kg h(-1). Results revealed that electrical, thermal and exergy efficiency of photovoltaic panel increases under higher flow condition and it is found as 8.05, 8.81 and 9.44%, 11.43, 20.8 and 22.17 and 19.38, 20.58 and 21.16% for mass flow rates of (m(f)) 4.68, 7.56 and 10.08 kg h(-1), respectively. When the m(f) increases, there is a decrease in the PISPB still distilled water production rate, thermal and exergy efficiency, and there is an increase in power production, electrical, thermal and exergy efficiency through the photovoltaic panel.
