Solar contractors recommend using the latitude of your home s location as the degree of tilt.
Perfect roof pitch for solar panels.
For example the latitude of los angeles california is 34 degrees so the tilt of your solar panels would be 34 degrees.
This does not mean however that every rooftop solar array will be capable of producing the same amount of electricity.
If you are trying to install solar panels on a steep roof it may not be possible to place panels at the optimal tilt with traditional racking systems.
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.
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.
Ideally the roof should have a fairly steep pitch on it.
For optimum performance a solar panel should be at a 30 degree angle and face south or southwest.
