<human>:  How does the solar energy system work?
<bot>: The solar energy system works by converting the energy from the Sun's rays into electricity through photovoltaic (PV) cells. The cells are made of semiconductor material and take in the sun's light and convert it into direct current (DC) electricity. This electricity is then routed through an inverter, which converts it into alternating current (AC) electricity—the type of electricity used in homes and offices. AC electricity is then either used immediately or directed to the electrical grid, where it is used to power homes and businesses.
