Residential solar energy is the process in which households utilize solar power systems to generate electricity while satisfying domestic energy requirements. Solar panels can be placed on the roofs or in the yards of homeowners where they can directly collect sunlight to transform it into usable electricity. These systems can be grid-tied which permits selling excess power back to the grid, or off-grid, providing full energy independence. Solar energy systems offer an array of advantages which include mitigating expenses associated with electricity usage, enhanced property value, environmental responsibility, renewable fuel sustainability, energy independence with backup power alternatives, and increased home value. Advances in technology and government policies have made solar energy systems easier for most homeowners to install and access.
