Maximum Roof Pitch For Solar Panels

Ideally a fixed roof mounted solar energy system should be at an angle that is equal to the latitude of the location where it is installed.

Maximum roof pitch for solar panels.

As well as the orientation the angle at which the panels are pitched is important. Between south west and south east.
