Gujarat has installed more PM Surya Ghar systems than any other state, close to 5.9 lakh homes by May 2026. Sunshine is strong and approvals are quick. The catch is the low rate paid for surplus units, so sizing to your own use matters more here than anywhere.
At a glance
- Subsidy: ₹78,000 for 3 kW from the centre. Gujarat’s old state top-up has ended.
- Surplus units have been bought at about ₹2.25 each, far below what you pay per unit.
- Each kW makes about 1,510 units a year, among the highest in India.
- PM Surya Ghar systems need no separate agreement with the DISCOM since November 2025.
Rooftop solar for homes in Gujarat
Who supplies your power
Four state DISCOMs under GUVNL: DGVCL in the south around Surat, MGVCL in central Gujarat around Vadodara, PGVCL in Saurashtra and Kutch around Rajkot, and UGVCL in the north around Mehsana. Torrent Power supplies Ahmedabad, Gandhinagar and Surat city.
Subsidy
You get the central subsidy: ₹30,000 for 1 kW, ₹60,000 for 2 kW and ₹78,000 for 3 kW or more. Gujarat’s earlier state top-up under the Surya Gujarat scheme has closed. See the PM Surya Ghar guide.
Net metering and the surplus rate
Homes use net metering, and since 2021 the system size is not limited to a share of your sanctioned load. Units you export are first set against units you import. Any surplus left at settlement has been bought at about ₹2.25 a unit. GERC’s fifth amendment of November 2025 removed the need for a separate agreement for PM Surya Ghar systems.
A draft regulation published in June 2026 proposes net metering from 1 kW to 1 MW with surplus settled every billing cycle. It is not final yet, so check the rules in force when you apply.
How much your roof makes
Using PVGIS data, a south-facing system in Gujarat makes about 1,511 units per kW a year. That is about 126 units a month per kW, so a smaller system covers the same bill than it would in most states. See month-by-month units for this state.
Tariffs
GERC kept home tariffs for 2026-27 at the previous year’s level. The energy charge on your bill is modest, but a fuel surcharge (FPPPA) that changes every quarter adds a large share, so use the total on your latest bill, not the slab rate, to work out your saving.
Worked example: sizing a home using 300 units
At 126 units per kW a month, 300 units needs about 2.4 kW. Rounding up to 3 kW earns the full ₹78,000 subsidy but makes about 80 units more than the home uses each month.
| 2.5 kW | 3 kW | |
|---|---|---|
| Solar units a month | About 315 | About 378 |
| Surplus units a month | About 15 | About 78 |
| Subsidy | ₹69,000 | ₹78,000 |
| Value of the surplus at ₹2.25 | About ₹400 a year | About ₹2,100 a year |
The extra half kW costs roughly ₹25,000 before subsidy, of which the subsidy covers ₹9,000. Earning back the remaining ₹16,000 at ₹2,100 a year takes around eight years. It is still worth it if your use is growing, for example with an EV or an extra AC; otherwise 2.5 kW is the tighter buy.
Open access solar for businesses in Gujarat
Businesses with a contracted load of 100 kW or more can buy solar from a plant elsewhere in the state through open access. What decides the real price is the set of grid fees below.
| Fee | Value |
|---|---|
| Grid usage fee (wheeling) | Not verified yet |
| Transmission fee | Not verified yet |
| Cross-subsidy fee (CSS) | Not verified yet |
| Extra DISCOM fee (additional surcharge) | Not verified yet |
| Other small fees (SLDC etc.) | Not verified yet |
| Power lost on the way | Not verified yet |
| Fee for saving power (banking) | Not verified yet |
Gujarat is one of the two states analysts most often rate as having the most favourable open access framework, along with Karnataka.
What we’ve verified
GERC has held HT energy charges flat at ₹4.30/kWh for three years, and the all-in grid price for HT consumers lands around ₹7.50–8.50/kWh. Banking costs ₹1.50/kWh, which is the main open access cost to model here. Because it is charged per unit rather than as a share of banked units, enter it under “Other small fees” in the calculator for the units you bank.
Frequently asked questions
Does Gujarat give a state subsidy for rooftop solar?
Not at present. The Surya Gujarat top-up has ended, so homes get the central PM Surya Ghar subsidy of up to ₹78,000.
What does the DISCOM pay for surplus solar units in Gujarat?
Surplus has been bought at about ₹2.25 a unit. New rules proposed in 2026 may change how and when it is settled.
Is there a size limit on home rooftop solar in Gujarat?
Since 2021 the size is no longer limited to a share of your sanctioned load. Size to your own use, because surplus earns little.
Which company supplies Ahmedabad and Surat?
Torrent Power supplies Ahmedabad, Gandhinagar and Surat city. The rest of Gujarat is supplied by DGVCL, MGVCL, PGVCL and UGVCL.
