Photovoltaic cells in the panel absorb photons from sunlight, knocking electrons loose in the silicon. That flow of electrons is direct current, which an inverter converts to the alternating current a home can use.

Solar panels rely on the photovoltaic effect: sunlight excites electrons in a semiconductor, generating an electric current that an inverter turns into usable AC power for the grid.
