Experimental investigation of photovoltaic-thermal hybrid solar collector
Latvia University of Agriculture, Liela Street 2, Jelgava, LV-3001, Latvia;
From August 6 2011 till September 29 2011 an experimental investigation of hybrid classic photovoltaic-thermal solar collector MWPVT-1414 was carried out. The hybrid solar battery had produced 23.01 kWh of electric energy during 55 days of investigation, or 0.418 kWh per day on average. It was calculated that during the summer months from March 1 till November 1 the amount of electric energy produced by the battery could be about 100 kWh. The highest cooling water temperature was 43°C, which is 16°C higher than the surrounding air temperature.
