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.
Now, we are going to discuss about why we require such sort of metering:
Control Electricity Bills
Consumers are allowed to produce their own power efficiently by the net energy meters. At day time, most of the solar consumers generate more power than they use; net metering permits them to export that electricity to grid and reduce the electric bills.
Protect Electric Grid
The net metering policies make a smooth demand curve for the electricity and permit the utilities to manage peak electricity loads in a better way. By encouraging production near to point of consumption, net energy metering reduces strain on distribution system and restricts loss in long distance power distribution and transmission.
