Solar Angles
As the world continues to move toward an increase in renewable energy sources, one of the most important components of a successful solar energy system is understanding the solar angles of your property. The first step to understanding solar angles is to understand the difference between orientation and tilt. The orientation of solar panels is the direction they face relative to the sun, while the tilt is the angle of the panel in relation to the ground. Both orientation and tilt are important considerations when designing a solar energy system.
The Solar angles are important factors to improve the power conversion efficiency. To determine the angle of incidence θ between a direct solar beam and the normal to the surface, the surface azimuth ψ and the surface-solar azimuth γ must be known.
