Chandigarh net metering rules
- Net metering is allowed for solar systems up to 500 kWp at one premises; larger systems use net billing (JERC Net Metering Regulations 2019, reg. 4.1, as amended 2024). Source
- The system must not be larger than the consumer's sanctioned load or contract demand (reg. 4.4). Source
- Excess exports are carried forward to the next bill as credited units. When imports are larger, the discom bills the net consumption (reg. 11.2). Source
- Credits left at the end of the financial year are bought at the lower of APPC or the feed-in tariff for that year, without subsidy. The credits then reset to zero (reg. 11.3). Source
- Payment is due by 31 May; later payment carries a surcharge of 1.25% a month. Systems under these regulations pay no banking charges (regs 13, 14). 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.

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.
