Best roof for solar panels
Comments (8)Depending on the point of view. Since most roofs are asphalt shingled, solar installers would be very familiar with the installation. Some prefer to work with asphalt shingled roofs. Metal shingle roofs require more care, but will last much longer than asphalt shingles and reduce the solar heat gain in the attic. Clay tile roofs could be really problematic for some solar installers. In any case, the mounts have to be treated as plumbing vents and flashed accordingly. For metal shingle roofs, there are no direct penetration mounts which can be used. The fasteners are not exposed at all. Standing seam roofs with non penetrating mounts are also a very good option. If you're concerned about the solar heat gain, use a cooler color or more IR reflective roof material. Solar electric generation also declines with increased temperature. You could have the mounts installed first. In some counties, new homes have to be constructed PV ready - mounts are required....See MoreInstalling Solar Panel on Chemwood Roof
Comments (1)Some solar installers do that with fragile roofs - clay tile, where they remove a good chunk of the original and put down composition shingle. Depending on how things are done, there could be problems for the lower portions of the roof if the water run off is channelled between the roofing felt and the chemwood roof....See MoreUsing used solar Panels
Comments (9)When we bought our home about a year ago it was disclosed there was a leak in the roof as a result of the solar panel installed, but repaired. We've had the roof leak and we are about to repair the roof (terra cotta tile). The install wasn't properly done to insure against leaks and the repair made was caulking. We have to hire a solar company to remove the panels while the roof repair is done and to reinstall the panels. We have been told by the solar company referred to us by our pool maintenance/PB that the solar panel is on it's last legs. The first solar company just gave us a quote to remove and replace but didn't go on the roof. We'll be getting more estimates now, but how long do solar panels usually last? We are in San Diego....See MoreFlow of Solar on the roof panels
Comments (1)Yes it matters, flowing from the bottom to the top of the panels helps to purge any air that may be trapped in the panels. If air gets trapped in the panels, they will not transfer as much heat to the water....See MoreElmer J Fudd
