Roof?<\/strong><strong><\/strong><\/h1>\n\n\n\n<p>In many cases, yes.<\/p>\n\n\n\n<p>Solar panels provide partial shading that helps protect roofing materials from direct sunlight, ultraviolet (UV) exposure, and extreme temperature fluctuations.<\/p>\n\n\n\n<p>Research published by the <strong><a href=\"https:\/\/www.nrel.gov\/\" target=\"_blank\" rel=\"noopener\"><mark class=\"has-inline-color has-vivid-cyan-blue-color\">U.S. National Renewable Energy Laboratory (NREL)<\/mark><\/a><\/strong>\u00a0has shown that rooftop PV systems can reduce roof surface temperatures by providing shade, which may help reduce thermal stress on roofing materials under certain conditions.<\/p>\n\n\n\n<p>Although roof lifespan depends on many factors, properly installed solar panels may contribute to reducing weather-related aging in exposed roof areas.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n\n\n\n<h1 class=\"wp-block-heading\"><strong>Choosing the Right
