ESTIMATION OF DAILY ENERGY GAIN OF SOLAR TRACKING SURFACES BASED ON GEOGRAPHIC POSITION

The performance of solar systems depends on the effective incident energy capture surface. This factor is dependent geographic position, orientation surface, atmospheric conditions, and other geo-climatic factors. Solar trackers, typically uni- biaxial, are used to optimize radiation via movement plane incidence these devices. A reliable estimation gain trackers with respect a fixed surface facilitates more accurate analyses feasibility, operation, maintenance ventures. In this work, method for estimating relative biaxial developed. approach applies locations between Arctic Circle Antarctic Circle, using coordinates altitude location interest, providing daily results throughout year. Unlike empirical or case studies, proposed any has low error. It can be implemented iterative algorithms computational cost easily utilized by researchers technicians in field.
