Standoff Solar Panel Mounting 101
As we have discussed in the past, keeping your solar panels cool is important to receiving the maximum efficiency out of your solar electric system. How you mount your solar panels on your roof make a difference on how cool they will operate. Standoff mounting is the most popular method of mounting solar panels on sloped roofs.
Standoff mounting works by attaching standoffs to the roof's structural support which holds rails, solar panels are mounted on top of the rails. The standoff allows a space of three and five inches between the solar panels and the roof. Keeping space between your solar panels and the roof serves an important function by allowing air circulation which keep your solar panels running cool.
