Opting to use solar mounting products that use silicone gaskets over EPDM gaskets is the best choice, particularly when looking to mount a PV system on a roof with asphalt shingles. . To address the myth, it's important to grasp how solar panels function and the temperatures they can reach during peak sunlight exposure. Solar panels are designed to absorb sunlight and convert it into electricity through photovoltaic cells. There are a number of issues that can crop up such as the fact that commercial roofs can't always sustain the weight. . For any rooftop solar system, making sure all the components of the solar mounting and racking system are compatible with the roof is of high importance — issues such as weight of ballast blocks on commercial roofs, the fire resistance of plastic components or chemical reactions between components. . Photovoltaic (PV) systems convert sunlight into electricity. These systems have been successfully installed on residential asphalt shingle roofs for many years. The two common attachment methods are rack-mounted and roof-integrated: The latter method is sometimes referred to as building integrated. . The installation of mounting feet / brackets for PV racking systems on asphalt shingle roofs has come a long way over the years.
