Optimization of the solar energy collection in tracking and non-tracking photovoltaic solar system

Experimental and theoretical analysis is made of the conditions of collection of solar radiation in solar tracking system without concentration, and in non-tracking system with standard and bifacial photovoltaic solar panel. For the experiments with solar tracking, an original Sun tracker was developed. The tracking effect calculated and measured shows an increase in energy collection around 30 - 40 %; bifacial panels with a reflector collecting solar radiation for the rear face give the corresponding increase of 50 - 60 % for the same panel area.
