Arunachal Pradesh net metering rules
- Prosumers of all categories can use net metering for systems from 1 kW to 500 kW (APSERC DRE Regulations 2024, reg. 6.3). Source
- A system cannot be larger than the sanctioned load or contract demand (reg. 6.8). Source
- If exports exceed imports in a billing period, the excess carries forward as credited units. Net imports are billed at the tariff order rates (reg. 11.1(d)). Source
- Units left at the end of the financial year are bought at the lower of the average power purchase cost and that year's feed-in tariff. Carried units then reset to zero (reg. 11.1(e)). Source
- The Department of Power works out the payment by 30 April of the following year (reg. 11.1(f)). Source
- Net-metered systems on the consumer's premises pay no banking or wheeling charge or cross-subsidy surcharge (reg. 14.1). 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.
