Residential solar installation involves setting up solar panels on the rooftops of homes or apartments to harness sunlight for electricity generation. This process includes several key components: solar panels, which capture sunlight and convert it into electricity; an inverter, which changes the direct current (DC) produced by the panels into alternating current (AC) for household use; and a mounting system that secures the panels to the roof. The installation process begins with a site assessment to determine the best configuration, followed by system design, permitting, and the actual installation. Once installed, the system is inspected to ensure it meets local regulations before being connected to the grid or set up for off-grid use.
