How Can Roof Angle Affect Solar Panel Performance?

To get the most from solar panels, you need to point them in the direction that captures the most sun.

Orientation, tilt and shading are of special importance, as they all have a major impact on the amount of sunlight that reaches the photovoltaic panels.

Most solar panels are mounted on rooftops, flat against the surface. But not every roof is angled to best capture the sun’s energy. For home solar systems installed in South Carolina, due south is the ideal orientation for harnessing maximum solar power.

Optimal tilt angle for a home solar system is equal to your home’s latitude. Since tilt can significantly affect solar power production, SuperGreen Solutions of Charleston factor in the roof angle when sizing a home solar system. For flat or low-sloped roofing, special brackets may be used to achieve a more favorable tilt angle. Shading is very important when designing a home solar panel system.

You could have a south-facing roof at the optimal tilt angle, but if the panels are shaded, your solar energy production never reach their full potential. SuperGreen Solutions of Charleston will perform an analysis to determine how much the solar panels will be affected by shade from nearby trees.
