Uttar Pradesh net metering rules

  • Domestic (LMV-1) consumers can use net metering. The system can be up to 100% of the sanctioned load (UPERC Rooftop Solar PV Regulations 2019, as amended in 2022). Source
  • Surplus is carried forward to the next bill as a credit, and the discom bills the net units. The settlement year runs from April to March, and credits unused at its end are paid at ₹2 a unit (UPERC net metering consultation paper). Source
  • Fixed or demand charges and government levies are payable whatever the credits; rooftop systems pay no wheeling charge or cross-subsidy surcharge. 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.
