Solar panels harness the sun’s energy through photovoltaic cells, converting it into usable electricity. As long as sunlight is present, the panels continue to collect energy, providing a renewable source of power. When combined with the utility power grid, solar energy enables users to enjoy free electricity during the day. Power from the grid is still available at night or when energy consumption exceeds solar production. Excess energy generated by the solar system can be stored in batteries or fed back into the grid through net metering, allowing users to potentially earn credits or compensation for the surplus electricity they generate.
