Abstract

Solar PV cells convert solar energy directly into the electricity, more over the energy generation rate can improve by incorporating with tracking and concentrating system. By the use of 2-axis tracking system higher improved in efficiency results. Present work shows significant effect of sun tracking system and concentrating system on energy generation capacity of photovoltaic panel. The Peak energy generation from PV collector (with and without 2-axis tracking and concentrating) have been determined in this study, for location 11.2588° N and 75.7804° E Latitude and Longitude (Calicut city Kerala) in the month of March April and May. Design of concentrator was done by considering size of PV cell and concentrating ratio (40), cooling system is incorporate to improve the performance of PV cells. Monthly average daily irradiation on horizontal surface and ambient temperature were measured. The system performance ratio was determined. The system power output was measured with tracking and concentrating system and compared with performance of normal PV cell. Power generated by PV cell with concentrating and tracking system is 112.56% more than power produce by PV cell without concentrating and tracking system.
