Abstract

Abstract: Depending on solar radiation calculation mode for inclined PV panel, yearly global radiation on surfaces tilt at different angles were calculated on several years. Historicaly change was obtained on optimum tilt angle. Yearly north-south step tracking for PV panels were researched by two, four, twelve steps according to different intervals like half year, season and month. Optimum tilt angels and corresponding radiation plus for different tracking time intervals and the whole year were calculated. To maximize yealy global radiation, the effects of different install modes were analyzed.

Key words: solar radiation, PV panel, optimum tilt angle, step tracking
