Solar panels were first invented in 1883 and convert sunlight into electric power. There has been significant advancement in solar technology, with most governments now funding conversion to renewable energy sources. Solar installation in the US has increased rapidly since 1989, generating over 86,000 megawatts of power. Solar panels are made of silicon and germanium semiconductors that collect photons from sunlight and convert them to electricity, either storing it or sending it back to the power grid. Using solar energy reduces carbon emissions, saves the ozone layer, and makes homes more energy independent and efficient over time.
