Tips What Is the Difference Between DC Power and AC Power?

AC stands for alternating current. AC voltage alternates direction, changing from a positive voltage to a negative voltage and back. The number of times it changes per second is measured in hertz (Hz). In the United States, AC power is 60 Hz, so it alternates 60 times every second. DC stands for “direct current”, which does not alternate. DC voltage always moves in one direction. A solar panel produces DC power, but your home needs AC power. This is why you need an inverter or microinverter to convert DC to AC.
