The amount of energy that a PV system produces has a direct relationship to the amount of sunlight that it receives. Shade therefore has a significant effect upon production. It is ideal for PV modules to be in a location without any shading during the entire day and throughout the year, unfortunately this is often not the case. As the sun rises or falls in the sky, its angle becomes lower and the shadows that are cast become longer, which means that shade is an inevitability in most locations. If a PV module can be kept shade free from 9:00 to 15:00, its production will not be severely affected, but shading during these crucial hours when the sun is at its strongest will cause a significant drop in production. How badly production will be affected will depend upon a few different factors:
