Solar panels should be mounted at a height of 3. 25″ from the roof's surface to ensure optimal performance. This measurement takes into account the seam of the SSMR, typically 1. 5″ to 3″ in height, the mounting hardware, adding approximately ¾” and the module frame, contributing another. . Determining the correct solar panel height above roof affects energy output, roof longevity, and compliance with local codes. The height impacts wind uplift resistance, snow shedding, air flow for cooling, ease of cleaning, and ease of electrical wiring.
