Solar Panel installation vs. Solar Shingles. The major difference between solar roof shingles and solar panels is in the installation process. Installers usually need to bolt solar panels onto the roof, which requires drilling through the roof and can violate its warranty.
Solar energy is the technology used to harness the sun's energy and make it useable. As of 2011, the technology produced less than one tenth of one percent of global energy demand. Many are familiar with so-called photovoltaic cells, or solar panels, found on things like spacecraft, rooftops, and handheld calculators. The cells are made of semiconductor materials like those found in computer chips. When sunlight hits the cells, it knocks electrons loose from their atoms.
