Abstract

PV panel tilt and sun tracking are crucial aspects of PV conversion efficiency. We propose an
analytical methodology for estimation of the optimal PV panel tilt based on calculation of the
sun`s position and the application of a clear-sky solar irradiance model. Our methodology outputs
three angles referencing a geolocation and the moment of interest: the incidence angle q, the
sun altitude a and the sun azimuth z. The irradiance model estimates the solar irradiation at 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 maximally 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 a single optimal annual fixed β The preliminary simulations produced
promising results consistent with the practical engineering implementations
