Haryana net metering rules
- An LT consumer's rooftop system must not be larger than its connected or sanctioned load. Net metering is allowed up to 500 kW (HERC Rooftop Solar Regulations 2021, reg. 5.3). Source
- Excess exports are carried forward to the next bill as credit within the settlement period. The discom bills the net consumption (reg. 11.1(c), 11.1(d)). Source
- Since the 2025 amendment, the settlement period runs from 1 October to 30 September, and the old 90% generation cap is deleted (2nd Amendment 2025, clauses 2 and 3.1). Source
- Credits left at the end of each settlement period are bought at 90% of the feed-in tariff in reg. 11(iii)(b) (2nd Amendment 2025, clause 3.2). Source
- The feed-in tariff in reg. 11(iii)(b) is ₹3.11 a unit, fixed for five years from 2021. So the year-end rate is about ₹2.80 a unit. Source
- Rooftop systems pay no wheeling, cross-subsidy, transmission, distribution or banking charges. Fixed charges, duties and levies stay payable (reg. 11.3, 12). 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.
