Solar energy metering or Net energy metering or net metering permits customers who generate their own solar electricity to monitor their energy consumption as well as production. When more electricity is produced than required, excess power is returned to grid through power meter by reversing meter from its normal direction. As a result of energy meter working in both the directions – one way to measure purchased power (when on-site need is more than on-site power production), the other way to measure returned power to grid – the consumer pays the ‘net amount’ of both the transactions.
