Pitch and Rooftop Mounting Solar Power in Massachusetts and Rhode Island
In designing a rooftop solar energy mounting system, Southern Light Solar takes every important factor into account. For our region, this includes defining the best solar panel tilt angle to get the best energy generation results. When that optimum angle cannot be met, we can predict the small efficiency changes across the four seasons.
Modern solar panel and solar power inverter designs help to minimize this condition, and in almost every case the cost and appearance of forcing a solar panel tilt different from roof pitch make it not a good idea.
For Massachusetts and Rhode Island the midday summer sun appears to be mostly overhead. A perfect solar panel tilt might be close to 70 degrees, making it appear nearly flat. In the dead of winter, the sun is still bright, but the best angle might be closer to 30 degrees as the sun drops lower in the sky.
Even the best fixed mounted design will be a compromise taking these optimum solar panel tilts into account. Conforming to the existing roof pitch means the best compromise angle may not be met. However, the efficiency impacts are small enough that often Southern Light Solar can design in and additional solar panel or two to compensate and meet solar power production targets.
Different architectural styles such as a hip roof, gable roof, gambrel roof, etc., usually offer their own roof pitch for aesthetic purposes.
