Quick Answer
The ideal installation angle for small solar arrays on a shed roof is between 30 to 45 degrees, depending on the latitude of the location and the amount of shading the array experiences. This range allows for optimal energy production and minimizes snow accumulation. A steeper angle may be required in regions with high snowfall.
Choosing the Right Angle
When selecting the installation angle, it’s essential to consider the latitude of the location and the type of roof. A shed roof typically has a relatively flat surface, making it ideal for solar arrays. For a shed roof in a region with a latitude between 30 and 50 degrees, an angle of 35 degrees is a good starting point.
Accounting for Shading and Snow
If the solar array experiences significant shading, a steeper angle of 40 to 45 degrees may be necessary to compensate for the reduced energy production. Conversely, in regions with high snowfall, a shallower angle of 25 to 30 degrees can help minimize snow accumulation. It’s crucial to consider the local climate and adjust the angle accordingly.
Practical Installation Considerations
When installing the solar array, ensure it’s securely fastened to the shed roof and pitched towards the south (in the Northern Hemisphere) for maximum energy production. A slight adjustment in the installation angle may be necessary to accommodate the roof’s curvature or any obstructions. Regular cleaning and maintenance are also crucial to ensure optimal performance.
