Net Metering

The customer generates electricity using solar panels fixed on their rooftops which are connected to the grid through a net metering system. The consumer has to pay only for the net amount of electricity that was consumed. If the solar electricity production exceeds the electricity consumption of the premises, the balance amount can be carried forward to future use upto 10 years. No fee will be paid for the excess electricity produced. Existing net metering customers can switch to other schemes if they wish to. However, the accumulated electricity units prior to the signing of new agreement shall not be carried forward.

Net Accounting

If the electricity generation of solar rooftop system is greater than the consumption, the consumer will be paid for the excess according to the below table.
