Himachal Pradesh net metering rules
- Net metering is allowed up to 50 kWp. Larger systems use net billing (HPERC Rooftop Solar Regulations 2015, reg. 4A, as amended 2022). Source
- A consumer with sanctioned load of 10 kW or less can install up to 10 kW, and the load is deemed raised. Single-phase LT is limited to 10 kWp (Third Amendment 2024, reg. 5). Source
- Net exports are carried forward as units to the next bill within the settlement period. The settlement period is up to 12 billing months from about 16 March (reg. 2(21), 4A(e), 10(3)). Source
- For approvals from 1 September 2022, credits left at the end are paid at 50% of HPSEBL's weighted average rate for small ground-mounted solar. With a subsidy, the share falls to 40%, 30%, 25% or 15% (reg. 10(9)(b)(iii)). Source
- HPSEBL's weighted average rate for the FY 2025-26 settlement was ₹3.777 a unit. The payment is ₹1.511, ₹1.133, ₹0.944 or ₹0.567 a unit by subsidy band. Source
- The amount falls due on 30 June after the settlement period. Unpaid credits do not carry into the next period (reg. 10(5), 10(6)). 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
PM Surya Ghar central subsidy: ₹30,000 a kW for the first 2 kW and ₹18,000 for the third kW, no more above 3 kW (₹78,000 at most). Grid-connected homes only, domestic-made modules, once per home.

Himachal Pradesh is a special category State: the subsidy is ₹33,000 a kW for the first 2 kW and ₹19,800 for the third kW (₹85,800 at most). The calculator uses these rates. See the PM Surya Ghar subsidy calculator.
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.
