All solar panels contain photovoltaic (PV) cells. PV cells absorb sun particles, or photons, and separate electrons from their atoms to produce direct current (DC) electricity. A solar inverter converts DC electricity into alternating current (AC) electricity, which can be used to power your home. This usable energy flows through your electrical panel and is distributed to where you need it. Unused electricity flows back to the grid through the utility meter, adding credit to your future bills.
