The importance of solar irradiance and meteorological data for PV

As the Earth rotates, sunlight strikes the surface at different angles, ranging from 0° (just above the horizon) to 90° (directly overhead). The more perpendicular a light source is to a surface, the more radiation the latter receives, so solar panels receive more sunlight and heat at midday than in the early morning.
