Ideal Roof Angle For Solar Panels

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.

Ideal roof angle for solar panels. However pitch angles between 30 and 45 degrees will work well in most situations. Since solar panels are more productive when the sun s rays are perpendicular to their surfaces the certainly best orientation is the one directly true south azimuth angle 180. 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. Forbes cited one study that had bloggers questioning whether panels should really face west.

Many roofs are going to have slopes between 30 and 40 degrees which means that solar panels can lie flush against the roof and produce enough electricity for attractive returns.
