They use this sunlight to create direct current (DC) electricity through a process called "the photovoltaic effect. . At a high level, solar panels are made up of solar cells, which absorb sunlight. Ultraviolet (UV) radiation – UV has higher energy than visible light. While it contributes to the total amount of energy that can be harnessed, it is less efficient in generating electricity. Here's a deeper look into the full process: To find out how solar power works, you need to. . Solar technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate solar radiation.
