Abstract
How can one maximize the solar irradiation energy received by a fixed flat solar panel? The orientation of a solar panel is determined by two angles: the tilt angle and the azimuthal angle. pysolorie stands for Python Solar Orientation Analysis of Solar Panels. It is a Python package designed to find the optimal tilt angle of solar panels, β, to maximize the beam energy received for a given day, assuming a clear-sky condition. For modeling the clear sky, we use the Hottel’s model. The optimal azimuthal angle is zero.
