About DC and AC electricity. Direct current (DC) electricity is what solar panels produce and what batteries hold in storage while alternating current (AC) electricity is the type used on the grid and in most household devices. A device called an inverter is required to convert the DC electricity from solar panels into appliance-friendly AC.
