How do you install solar panels on tile roofs?Ī preferred technique utilized to install SunPower’s highly efficient solar panels on a lightweight tile roof is called an inset solar installation, sometimes referred to as a “comp-out.” This process will add additional steps and costs to your solar project but will give you long-term durability and help prevent potential damage to your home.ĭuring this process, a roofing professional removes the existing tile roof from the area where the solar array will be installed and lays new composite shingles in its place. Because lightweight tiles are fragile, vibrations that occur from wind passing between the panels and the racking system sitting on top of the tiles can result in future incidents. If this method of installation is pursued and solar panels are successfully mounted without tile breakage, there is still a possibility of issues down the road. Although this method may work for heavyweight tiles, lightweight tiles that are not removed are still at risk. Some solar installers will choose to remove individual tiles and replace them with special tile replacement mounts. Drilling through these tiles may also result in damage to the base layer of your roof called the underlayment, which is used for extra protection below tiles or shingles. Breaks or cracks can occur during the solar installation process, potentially compromising roof integrity and leading to leaks and other damage to your home.
