Odisha net metering rules
- Net metering is allowed up to 500 kW or the sanctioned load, whichever is lower, within 75% of the transformer capacity (OERC order, amended 5 May 2022, cl. 1(vi)(c)). Source
- Exports above the home's use in a billing cycle are carried forward to the next bill. Net imports are billed at the normal tariff for the category (OERC Net Metering Order 2016, cl. 12(b)-(c)). Source
- Solar credit for the year is capped at 90% of the home's consumption. Excess above that at year end is free energy, and nothing carries into the next year (cl. 11(a)-(b)). Source
- The 2025 amendment allows hybrid inverters and data loggers; it does not change the settlement rules (OERC order of 27 November 2025). Source
Default generation of 100 units per kW a month: the Union Cabinet's PM Surya Ghar note says a 3 kW system 'will be able to generate more than 300 units a month on an average'. Source

Rooftop solar questions
How does net metering work?
A two-way meter records what you draw from the grid and what your panels send to it. On each bill the units you exported are taken off the units you imported, and you pay for the net units at the normal tariff. What happens to extra units depends on the state: some buy them every month, others carry them forward and settle at the end of the year.
How much does a 1 kW rooftop system generate?
The Union Cabinet’s note on PM Surya Ghar says a 3 kW system makes over 300 units a month on average, about 100 units per kW. MNRE says 1 kW can make 4 to 5.5 units on a clear sunny day. Your roof’s direction, shade and dust change this, so you can edit the figure.
How much is the PM Surya Ghar subsidy?
For homes: ₹30,000 a kW for the first 2 kW and ₹18,000 for the third kW, so ₹78,000 for 3 kW or more. Higher amounts apply in special-category states. The system must be grid-connected and use domestically made modules, and a home can get it only once. The scheme runs until 31 March 2027.
Do I still pay a fixed charge with solar?
Yes. In every state covered here, fixed charges and government levies stay payable whatever your solar credits.
