For instance in the san francisco bay area the best solar panel tilt angle is between 22 23 degrees.
Best roof angle for solar panels.
These angles will give you the best overall output over the course of the year if you re going for a fixed installation.
Overall the angle of your rooftop has less impact on solar panel performance than the direction your roof faces.
Each situation is unique in terms of roof angle property layout and power consumption.
While the general consensus in the solar power industry is that either west or south is the best direction for solar panels to face these two options don t necessarily address the needs of every individual solar user.
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.
In case the roof is very steep you may not be able to get the most optimal tilt angle for the panel especially if it is lower than the angle of the roof.
However pitch angles between 30 and 45 degrees will work well in most situations.
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.
Most roofs have an inclination of 30 to 40 degrees.
For los angeles a solar panel tilt of 19 degrees works the best.
At this level the solar panel can lie flat on the roof and get enough sunlight to produce enough electricity.
