Solar Net Metering, Working, Procedure, Sample Bill & Price in India

What is Solar Net Metering and How it Works

In Solar Net Metering excess electricity is fed into our electric utility’s/electricity board when our On-Grid or Hybrid Solar Power Plant produces more than our need, in that case our meter runs in reverse direction. When our system is not producing enough electricity as per our load, then we can draw it from your utility just like ordinary meter. Solar panels produce peak electricity in the afternoon, when many people aren’t home in peak times may be in offices. In home electricity use is typically higher in the evenings and mornings, then net metering helps you to reduce electricity bill by using Import and export Facilities.



The existing energy meter in our building or home will need to be replaced by a two-way (bidirectional) meter. This bidirectional energy meter or Net Meter is essential as it can measure both, energy import (from the grid to the Customer) and energy export (from the customer to the grid) separately.

Price of Net Meter:-

Price of Net meter is depend upon the Electricity Board usually available at Rs 4050 only.

Procedure for Solar Net Metering

This is the standard flow chart for Solar Net Metering. Because, in every state there are different type of Electricity departments or power distribution companies. So procedure of Net Metering may differ as per your state.

For PV system more than 20 kWp and up to 100 kWp, safety certificate issued by Charted Engineer shall be required. For PV system above 100 kWp Inspection of Electrical Inspector shall be required before commissioning.

• Work Completion Report:- Applicant shall submit the “work completion report” along with enclosures

• Commissioning of Rooftop Solar PV System:- Applicant may procured the meter from empanelled firm, if meter is not available in Nigam Store. Meter shall comply the specifications issued by Nigam. SDO (OP) and M&P team will connect the Rooftop Solar PV System with the Gird. After submission of work completion report and safety certificate by applicant, commissioning of system shall be done within 3 days.

Sample of Electricity Bill with Solar Net-Metering

This is the standard Electricity Bill with Solar Net Metering. Because, in every state there are different type of Electricity departments or power distribution companies. So rebates and method of calculation for Solar Net Metering bill may differ as per your state.

Sample of Electricity Bill with Solar Net Meter

Sample of Electricity Bill with Solar Net Meter

Illustration: If a consumer in Gurgaon located in Haryana imports 2927 kWh(units) in April billing month and exports 2376 kWh(units) in the same month, the consumer will be billed for only 551 kWh. If the import energy in the March period is 1500 kWh and the export again is 1600kWh, then the excess 100kWh will be carried forward to the next month’s bill or next billing cycle and adjusted there as we can see in the pictures. At the end of the financial Period if Solar energy is produce more than the consume units then solar energy export shall be determined.
