At a high level, solar panels are made up of solar cells, which absorb sunlight. They use this sunlight to create direct current (DC) electricity through a process called "the photovoltaic effect." Because most appliances don''t use DC electricity, devices called inverters then convert it to alternating current (AC) electricity, the form that
