For optimum performance a solar panel should be at a 30 degree angle and face south or southwest.
Perfect roof pitch for solar panels.
Overall the angle of your rooftop has less impact on solar panel performance than the direction your roof faces.
The ideal angle for solar panels is to have them angled at the same number of degrees as the latitude the panels are at.
In general solar panels can be installed on almost every form of roofing.
However pitch angles between 30 and 45 degrees will work well in most situations.
This does not mean however that every rooftop solar array will be capable of producing the same amount of electricity.
Ideally the roof should have a fairly steep pitch on it.
There are several factors in your control when it comes to finding the ideal pitch for your solar panels.
Solar contractors recommend using the latitude of your home s location as the degree of tilt.
For example the latitude of los angeles california is 34 degrees so the tilt of your solar panels would be 34 degrees.
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.
30 degrees is ideal but as long as it s not too steep to install safely the pitch is relatively unimportant.
