Solar net metering enables commercial and residential customers who generate their own solar power electricity to send the electricity they do not use back to the grid or to neighbours. This billing mechanism essentially allows home-owner to receive credits instead of paying for electricity. While the concept seems relatively simple, it has been the source of a significant amount of complexity.
Solar energy is generated either for self consumption or for export through bi-directional meter to Power Grid. The net difference between energy generated & consumed is indicated by-directional meter.
