How should you adjust the pitch of a solar collector mounted on a roof?

Adjusting the pitch of a solar collector mounted on a roof is best achieved by using cripples. Cripples are short framing members that can be added to support the solar collector at the desired angle. This method provides structural integrity while ensuring that the solar panels are positioned correctly to maximize sunlight exposure. The correct pitch is essential for achieving the optimal efficiency of the solar collector, as it affects both the amount of sunlight captured and the overall energy production of the system.

Altering the mounting frame is a viable method but typically involves more extensive modifications, which might not be practical in every situation. Manually adjusting the solar panels can be cumbersome and may not offer a permanent solution, leading to potential misalignments over time. Increasing the height of the collector may also impact the stability and wind resistance of the installation, which is not ideal and doesn’t specifically adjust the angle, making it less effective for achieving the desired pitch. Using cripples simplifies the adjustment process while maintaining the structural safety and functionality of the solar collection system.
