What angle should solar panels be installed on a flat roof?

Installing panels at a fixed angle might capture less sunlight during winter when the sun is lower, meaning you won't get as much energy for your home. The optimum angle for solar panels on flat roofs is around 30 to 35°. This angle helps the panels balance, maximising solar energy production and allowing rain to flow off them easily.

What is the angle of incidence of a solar panel?

Angle of Incidence, θ: This is the angle between the line that points to the sun and the angle that points straight out of a PV panel (also called the line that is normal to the surface of the panel). This is the most important angle. Solar panels are most efficient when pointing at the sun, so engineers want to minimize this angle at all times.
