A to Z of solar power: Part 1
Alternating current (AC) and direct current (DC), relate to the energy, or current, produced by solar panels and the type of current your house uses. The energy produced by solar panels is DC (think of a river flowing in one direction), while houses use AC (now think of that river switching directions multiple times per second). Before the solar power can be used by your home, the DC current needs to be converted into AC, which is carried out by an inverter.
