Effect of weather conditions on the Hybrid solar PV/T Collector in variation of Voltage and Current

Abstract

A laboratory scale hybrid solar air collector has been developed and tested for unload conditions at the Maulana Azad National Institute of Technology, Bhopal, India. The collector has been tested under two weather conditions firstly in clear sky and secondly in cloudy and partly hazy. The cell temperature in the clear sky conditions is found to higher than other weather conditions. The reduction in cell temperature in cloudy and partly hazy weather condition vary from 4.4-15.2 ⁰C as compared to the clear sky conditions. Experimental result reveals that there is a slight increase in the voltage and current in cloudy and partly hazy weather conditions as compared to clear sky conditions due to low ambient temperature.
