Whats DC vs AC power?
Solar modules produce electricity that flows in only one direction. From positive to negative or Direct Current (DC). Your home however runs on electricity that flows in both directions or Alternating Current (AC). An inverter is needed to change the DC power from the solar panels into AC electricity to power your home. This AC power must also be “in phase” with the power supplied by the utility companies allowing it to be compatible with the electric power grid.
