Net metering is referred to as the policy that deals with excess energy generated by your solar panels; this energy is fed back into the grid so that your energy meter runs in reverse and results in a credit for energy provided. The reverse occurs when you draw energy; the energy meter rotates forward. In an ideal situation, a farmer draws the same amount of energy from the grid as he provides, resulting in a net zero energy requirement and a zero electricity bill. However, this depends on your power company having a net metering policy and on the amount of solar you can harness.
