Where is the best location to install solar panels?

The best place to install solar panels is on the south-facing section of an unshaded roof. This gives the panels the best environment in which to generate electricity. Other orientations (having the panels facing a different direction) of solar panels will still work, and contrary to popular belief you don’t need constant sunshine beating down on them. But for best results, a sunny south-facing roof is the best place to install solar panels.

Why do solar panels work best when facing south? Well, in the UK, south-facing gardens get more hours of direct sunlight than those that face other directions. When sunlight (or daylight) hits the solar panels, it stimulates photons inside them, whose movement leads to the generation of electricity. So, the more light that hits the panels, the more energy they can make.

The best place to install solar panels should also be a location free of shade, for example that are cast by overhanging trees. Large shadows covering your panels will inhibit their ability to produce electricity from light.
