2 kW vs 3 kW Solar in Gujarat After the State Subsidy

Two WhatsApp PDFs, two sizes

Nilesh in Alkapuri had a 3 kW quote on the table. His cousin in Ahmedabad forwarded the 22 October 2026 GR and asked why anyone would still install 3 kW.

That is the right question. It is not a trick question with one patriotic answer.

Short answer: After the Gujarat GR, 2 kW vs 3 kW solar Gujarat is a subsidy-structure choice as much as a bill choice. 2 kW (strictly, DC up to 2.18 kWp) can collect extra state DBT and then cannot grow for three years. 3 kW collects the full PM Surya Ghar subsidy in Gujarat cap of ₹78,000 and sits outside that GR. Read the state subsidy guide before you cut a design only to chase 2.18.

UVR Green Energies will still survey solar in Vadodara, solar in Surat, solar in Bharuch, solar in Anand and roofs anywhere in India. The GR follows the DISCOM, not the municipal limit.

Two households, two sizes

Imagine two MGVCL homes on the same street in Vadodara.

House A uses about 180–220 units a month, two ACs, no EV. House B sits above 350 units most of the year, three ACs, a water heater, and an EV charger is “next Diwali”.

House A can often live on about 2 kW if the terrace is clean. House B will still be importing expensive slab units on a 2 kW plant, and the GR will then forbid adding panels for three years if they take the state benefit.

CFA versus the state GR

Central CFA did not move. PIB and MNRE still set ₹30,000 per kW for the first 2 kW, ₹18,000 for the third kW, cap ₹78,000 from 3 kW.

The GR only fills the hole between that CFA and the MNRE benchmark (₹50,000/kW for the first 2 kW, ₹45,000 per extra kW), after your 10% or 5% share, and only if DC ≤ 2.18 kWp, commissioned on or after 22 October 2026.

If the installer charges more than benchmark, you pay the gap. The GR is against benchmark, not against the invoice.

The 3-year expansion lock

This is the clause WhatsApp summaries skip.

The MGVCL-hosted GR says residential consumers who take this benefit shall not add further rooftop solar capacity for three years from the installation date. Homes that already have a smaller plant may add only up to a cumulative 2.18 kWp.

If House B takes 2 kW plus state DBT and then buys the EV, the extra modules are a policy problem, not a hardware problem.

3 kW does not trigger this GR lock, because 3 kW never entered the GR.

UVR rate-list example (CFA + state DBT up to 2.18 kW)

On UVR’s Gujarat on-grid list (Rayzon 550 Wp mapping in solarRates):

• Below 3 kW: ₹57,000 per kW → 2 kW gross ₹1,14,000. After ₹60,000 CFA and ₹30,000 general-category state DBT, estimated net ₹24,000.
• From 3 kW: ₹54,000 per kW → 3 kW gross ₹1,62,000. After ₹78,000 CFA, estimated net ₹84,000 (3 kW is above the 2.18 kWp state cap).

You pay the full installed cost upfront; central and Gujarat state subsidies are credited by DISCOM after commissioning. The 2 kW state transfer is from MGVCL, DGVCL, UGVCL, PGVCL or Torrent Power, not from the UVR booking invoice.

Yield planning on this site is 126 units per kW per month. 2 kW ≈ 252 units; 3 kW ≈ 378 units, before shade. Surplus after set-off is ₹2.25 a unit for five years under GERC’s Third Amendment — too low to justify a 3 kW plant on a 150-unit bill.

DCR modules remain mandatory for CFA. DCR vs non-DCR is not optional on a subsidised file.

Cities, DISCOMs, same fork

The GR names DGVCL, MGVCL, PGVCL, UGVCL and Torrent Power. So the 2 kW versus 3 kW fork is statewide: solar in Ahmedabad and solar in Gandhinagar on Torrent, solar in Rajkot on PGVCL, solar in Mehsana on UGVCL, solar in Ankleshwar and Bharuch on DGVCL, solar in Vadodara on MGVCL.

People still search Surya Gujarat yojana and solar subsidy Gujarat kitni milti hai. The extra 2026 rupees are not a revival of the old 40% SURYA capital subsidy. They ride on PM Surya Ghar. Apply on the national portal.

SC/ST share and the same size fork

The 22 October 2026 GR does not change the central CFA table. It changes how much of the MNRE benchmark you must fund before the state pays the remainder.

For general-category residential consumers, the GR expects a 10% share of the benchmark cost. For SC/ST residential consumers, the share is 5%. The state DBT is what is left after subtracting PM Surya Ghar CFA and that share from the benchmark — not from whatever gross price appears on a vendor quotation.

Either way, 3 kW is outside the 2.18 kWp DC cap for this state component. The ₹78,000 central cap still applies at 3 kW. The three-year expansion lock applies when you take the state benefit on a qualifying small plant, not when you choose CFA-only sizing at 3 kW.

Commissioning date and the ₹2,950 waiver line

The GR ties eligibility to systems commissioned on or after 22 October 2026. That is a commissioning clock, not the day you pay a booking advance. MNRE operational guidelines still require DISCOM inspection and approval before central CFA is processed. The state DBT follows the same DISCOM ecosystem — MGVCL, DGVCL, UGVCL, PGVCL or Torrent Power — with GUVNL as nodal agency for the state fund.

The same GR’s preamble also records an earlier Government of Gujarat order dated 05 August 2025 waiving meter, meter-testing, meter-box and connectivity charges totalling ₹2,950 for new rooftop solar up to 6 kW (residential and GHS/RWA common-facility plants). That waiver is a separate line item from CFA and from the 2.18 kW state top-up. It does not turn a 3 kW plant into a 2 kW plant for subsidy purposes.

If your file is still “applied but not commissioned” when the calendar crosses policy dates, the paperwork on the DISCOM file — commissioning date, net meter, inspection report — is what matters. UVR Green Energies does not treat a WhatsApp “done” message as commissioning.

Work the bill before the comparer

Start with twelve months of units, not with the subsidy checker output. MGVCL, DGVCL and Torrent Power all bill under GERC net metering: set-off inside the billing cycle, cheap surplus after export, fixed charges still due.

Use What size solar system do I need? as the sanity check. Then open the PM Surya Ghar subsidy checker and the comparer on this page to see central CFA plus Gujarat state DBT on UVR’s Gujarat list for 2 kW and 2.18 kW, versus central CFA only at 3 kW.

Yield on this site remains 126 units per kW per month for planning. Shade, orientation and inverter clipping change real production. Surplus after set-off is ₹2.25 per unit for five years on self-owned homes under GERC’s Third Amendment — a reason not to oversize purely for export income.

Portals, DCR and where the GR lives

None of this changes where you apply. CFA still starts on pmsuryaghar.gov.in with a registered vendor and DCR modules, as explained in DCR vs non-DCR. SURYA Gujarat at suryagujarat.guvnl.in remains the GUVNL DISCOM rooftop window MNRE lists for Gujarat — see National portal vs SURYA Gujarat.

The 2026 state rupees are not a third portal. They are a DISCOM DBT after a qualifying PM Surya Ghar file. UVR’s published Gujarat on-grid rate sheet now subtracts both central CFA and the extra state DBT for homes up to 2.18 kWp. You pay the full installed cost upfront; central and Gujarat state subsidies are credited by DISCOM after commissioning.

For the full GR walkthrough — consumer share, lock-in, who pays — read Gujarat state solar subsidy 2026. For policy context on surplus and sanctioned load, Gujarat Solar Power Policy 2021 still explains what GERC carried forward even though the 2021 GR’s operative period ended on 31 December 2025.

Housing societies follow a different CFA line (₹18,000 per kW on common facilities, capped in MNRE rules). This article is for single-meter homes. Society roofs in Vadodara are covered in housing society solar.
