Solar power, also known as solar electricity, is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Solar panels use the photovoltaic effect to convert light into an electric current. Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree. But have you ever wondered how they do it? At a high level, solar panels are made up of solar cells, which absorb sunlight. What actually happens inside a panel? Why does sunlight create usable power? And how does that electricity end up running your lights. .
