Solar Canopies (Structural Solar Supports) will stay cooler and operate more efficiently in the summer than roof mounted PV modules. With roof mounted solar, rails must be elevated to provide for air circulation between the modules and metal roof systems.
Although the RERH specification does not set a minimum array area requirement, builders should minimally specify an area of 50 square feet in order to operate the smallest grid-tied solar PV inverters on the market.
Rooftop solar installations are an efficient way to harness solar energy for residential or commercial buildings. Several factors need to be considered while selecting the appropriate configuration for the photovoltaic (PV) panels. These factors are all addressed in a solar site survey. The first thing to look at is the roof itself.
A conventional PV system that includes racking materials will add approximately 6 pounds per square foot of dead load to the roof or structure, though actual weights can vary for different types of systems. Wind will add live loads; the magnitude of live loads will depend on the geographic region and the final PV system.
