Abstract
PV panel tilt and sun tracking is crucial aspect for PV conversion efficiency. We propose an analytical methodology for estimation of optimal PV panel tilt based on calculation of the sun position and application of a clear-sky solar irradiance model. Our model outputs three angles referencing a geolocation and the moment of interest: the incidence angle, the sun altitude and the sun azimuth z. The irradiance model estimates the solar irradiation on a geolocation that can be used for PV conversion estimation based on specified tilt β. The moment PV power is used for calculation of the daily energy production, and the optimal β is identified in the tilt range of 0 to 90. Seasonal division of the year is performed and optimal seasonal tilt is estimated based on the maximal produced seasonal energy tested with every corresponding β. The methodology is tested on four typical seasonal models - 12 months, 4 three-month quarters, 2 half-year seasons and single optimal annual fixed β. Preliminary simulations produce promising results consistent with the practical engineering implementations.
