Ahmedabad is one of the best cities in India to install rooftop solar in 2026, and also one of the most price-transparent. The city’s competitive market, Gujarat’s strong solar policy, and active PM Suryaghar participation by both Torrent Power (inside the city) and UGVCL (outside it) mean that a 3 kW residential system costs ₹1,57,000–₹1,72,000 gross and just ₹79,000–₹94,000 after the ₹78,000 PM Suryaghar subsidy. With Ahmedabad’s irradiation of 5.5 to 6.0 kWh/m²/day, payback runs about 3 to 5 years, one of the fastest in India. This guide gives you the complete price table, a step-by-step value calculator, and everything that affects the final number before you call an installer.
Key takeaway. Solar panels in Ahmedabad cost ₹1,57,000–₹1,72,000 gross for a 3 kW system. After the ₹78,000 PM Suryaghar subsidy the net cost is ₹79,000–₹94,000. A 3 kW system generates about 380 to 420 kWh/month at Ahmedabad’s 5.5 to 6.0 kWh/m²/day irradiation. At an illustrative effective rate of ₹5.75/kWh, annual savings are about ₹26,000–₹29,000, giving a payback of roughly 3 to 3.5 years. Heaven Green Energy is MNRE-approved and UGVCL-empanelled for PM Suryaghar applications.
Ahmedabad’s solar economics stand out for three reasons: Gujarat’s irradiation of 5.5 to 6.0 kWh/m²/day is among India’s highest outside the Thar Desert zone; your highest-slab units, plus the fuel surcharge on every unit, are what solar offsets first; and the competitive installer market keeps gross prices below the national benchmark cost by ₹3,000–₹8,000/kW for Gujarat-based EPCs. The result is a city where solar is financially compelling for almost any homeowner paying above ₹2,500/month.
Why Ahmedabad Has India’s Best Solar Economics
Ahmedabad has two electricity licensees. Torrent Power supplies Ahmedabad city, and UGVCL (Uttar Gujarat Vij Company Limited) supplies areas outside the Torrent licence area. Your bill tells you which one you are on. Residential (RGP) energy charges under the GERC tariff schedules effective 1 April 2026 are:
| Monthly units | Torrent Power (Ahmedabad) | UGVCL (post-paid) |
|---|---|---|
| First 50 | ₹3.20/kWh | ₹3.05/kWh |
| 51 to 100 | ₹3.95/kWh | ₹3.50/kWh |
| 101 to 200 | ₹3.95/kWh | ₹4.15/kWh |
| 201 to 250 | ₹5.00/kWh | ₹4.15/kWh |
| Above 250 | ₹5.00/kWh | ₹5.20/kWh |
On top of these energy charges, both licensees bill a Fuel and Power Purchase Adjustment Surcharge (FPPAS) on every unit, revised periodically, plus a small monthly fixed charge. Your effective cost per unit is therefore well above the energy charge alone; divide the energy-related charges on your bill by the units billed to find it.
A typical 3 to 4 BHK Ahmedabad home with one or two 1.5T ACs consumes 300 to 450 units/month, so most of its units fall in the top slab. Those top-slab units, plus FPPAS, are what solar offsets first.
Complete Solar Price Table: Ahmedabad 1 kW to 10 kW (2026)
All prices are for complete on-grid turnkey systems from a vendor registered on the PM Suryaghar portal: ALMM-listed, domestic-cell (DCR) mono PERC panels as the subsidy requires, BIS-certified string inverter, mounting structure, DC/AC cabling, DCDB, ACDB, net metering application, and PM Suryaghar subsidy filing. Generation estimates use Ahmedabad’s 5.7 kWh/m²/day average with 0.80 system performance ratio.
| System Size | Gross Cost | PM Suryaghar Subsidy | Net Cost After Subsidy | Monthly Generation | Annual Saving (at ₹5.75/kWh) |
|---|---|---|---|---|---|
| 1 kW | ₹52,000–₹57,000 | ₹30,000 | ₹22,000–₹27,000 | 125 to 140 kWh | ₹8,625–₹9,660 |
| 2 kW | ₹1,05,000–₹1,14,000 | ₹60,000 | ₹45,000–₹54,000 | 250 to 280 kWh | ₹17,250–₹19,320 |
| 3 kW | ₹1,57,000–₹1,72,000 | ₹78,000 | ₹79,000–₹94,000 | 380 to 420 kWh | ₹26,220–₹28,980 |
| 5 kW | ₹2,62,000–₹2,87,000 | ₹78,000 | ₹1,84,000–₹2,09,000 | 630 to 700 kWh | ₹43,470–₹48,300 |
| 10 kW | ₹5,25,000–₹5,74,000 | ₹78,000 | ₹4,47,000–₹4,96,000 | 1,260 to 1,400 kWh | ₹86,940–₹96,600 |
Source: Heaven Green Energy benchmark pricing for Ahmedabad, 2026. PM Suryaghar subsidy as per the MNRE operational guidelines (June 2024). Annual saving uses an illustrative effective rate of ₹5.75/kWh (energy charge plus FPPAS); use the effective rate from your own bill.
The 2 kW subsidy figure of ₹60,000 reflects the MNRE schedule: ₹30,000 for the first kW + ₹30,000 for the second kW, and ₹18,000 for the third kW. For 3 kW and above, the subsidy is capped at ₹78,000.
The Ahmedabad Solar Value Calculator
The Ahmedabad Solar Value Calculator is Heaven Green Energy’s proprietary three-step framework for calculating your personal net payback before getting any installer quotes. It is built around Ahmedabad’s tariffs and irradiation profile.
Step 1: Gross Cost
Your gross cost is the full turnkey system price before any subsidy. In Ahmedabad’s 2026 market, expect:
- 3 kW: ₹1,57,000–₹1,72,000
- 5 kW: ₹2,62,000–₹2,87,000
- 10 kW: ₹5,25,000–₹5,74,000
Use the midpoint of the range for your calculation. For 3 kW: ₹1,64,500. For 5 kW: ₹2,74,500. These are for ALMM panels and BIS-certified inverters from a registered PM Suryaghar vendor. Prices below ₹52,000/kW should raise questions about panel quality or installer credentials. See the how to read a solar quote guide for what a legitimate itemized quote looks like.
Step 2: Subsidy
Subtract the PM Suryaghar subsidy from your gross cost:
- ₹30,000 for 1 kW
- ₹60,000 for 2 kW
- ₹78,000 for 3 kW and above
Net cost = Gross cost − Subsidy
For a 3 kW system at gross midpoint: ₹1,64,500 − ₹78,000 = ₹86,500 net cost.
The subsidy is only available through a vendor registered on the PM Suryaghar portal. Using an unregistered installer forfeits the entire ₹78,000. See the PM Suryaghar UGVCL guide for verification steps.
Step 3: Net Payback
Calculate your monthly solar savings using the effective rate per unit on your Torrent Power or UGVCL bill (energy charge plus FPPAS), then divide net cost by annual savings.
Savings for a 3 kW system generating about 410 kWh/month:
- At an effective ₹6.50/kWh: 410 × 6.50 = ₹2,665/month → payback = ₹86,500 ÷ ₹31,980/year = 2.7 years
- At an effective ₹5.75/kWh: 410 × 5.75 = ₹2,358/month → payback = ₹86,500 ÷ ₹28,290/year = 3.1 years
- At an effective ₹5.00/kWh: 410 × 5.00 = ₹2,050/month → payback = ₹86,500 ÷ ₹24,600/year = 3.5 years
Note: These figures assume 80% self-consumption and 20% net metering export. If your self-consumption ratio is lower (absent homeowners, daytime-empty houses), payback extends by 0.5 to 1 year. See the solar payback period explained guide for the export credit adjustment.
Green tip
Ahmedabad homeowners in newer residential areas, SG Highway, Bopal, Gota, Science City Road, often see faster payback because their large, unshaded south-facing RCC rooftops maximise generation, and their 3 to 4 BHK energy consumption lands in the top tariff slab. If you are in this category, a 5 kW system often delivers better ROI per rupee invested than a 3 kW system, even before accounting for tariff hikes.
What Drives the Price Range in Ahmedabad
The ₹15,000–₹25,000 range within each system size tier reflects four variables, not price gouging.
Panel technology and brand: ALMM-listed standard mono PERC panels from Waaree or Goldi Solar cost ₹22–₹25/Wp. ALMM-listed premium TOPCon panels from Adani Solar or REC cost ₹28–₹34/Wp. A 3 kW system (2,700 Wp effective) has a panel cost range of ₹59,400–₹91,800 for panels alone, explaining a large portion of the system price range. For Ahmedabad’s hot summers, TOPCon’s lower temperature coefficient means 3 to 5% more generation between March and June.
Inverter type: Standard string inverter (Growatt, Solis, Sofar) adds ₹12,000–₹18,000 for a 3 kW system. Hybrid inverter with battery-ready option: ₹25,000–₹45,000. Microinverters: ₹40,000–₹65,000 for the same capacity. For most Ahmedabad homes with few shading issues, a quality string inverter is the right choice.
Structure type: Flat RCC rooftop ballasted structure (most Ahmedabad homes): ₹5,000–₹8,000 for 3 kW. Anchor-drilled structure for sloped rooftops: ₹7,000–₹12,000. Pre-galvanized structures cost ₹3,000–₹5,000 more but last 15 to 20 years vs. 8 to 12 for standard GI.
Cable run and switchgear: Systems above the 2nd floor add ₹3,000–₹10,000 for longer DC cable runs. Systems with existing MCB panels in poor condition may need switchgear upgrades at ₹5,000–₹12,000.
Warning
Beware quotes below ₹52,000/kW in Ahmedabad. At Ahmedabad's current ALMM panel cost of ₹22–₹25/Wp and BIS inverter pricing, a legitimate complete turnkey system for 3 kW cannot be delivered under ₹1,55,000 gross with quality components. Quotes below this threshold typically involve non-ALMM panels, unverified inverters, or missing components like DCDB, surge protection, or workmanship warranty.
Solar Generation in Ahmedabad: Month-by-Month
Ahmedabad’s climate is well-suited to solar. The main variation is the monsoon (July–September), which reduces irradiation. Here is an estimated monthly generation profile for a 3 kW system:
| Month | Irradiation (kWh/m²/day) | Est. Generation (3 kW) |
|---|---|---|
| January | 5.2 | 374 kWh |
| February | 5.8 | 418 kWh |
| March | 6.4 | 461 kWh |
| April | 6.8 | 490 kWh |
| May | 6.5 | 468 kWh |
| June | 5.0 | 360 kWh |
| July | 3.8 | 274 kWh |
| August | 3.6 | 259 kWh |
| September | 4.5 | 324 kWh |
| October | 5.8 | 418 kWh |
| November | 5.5 | 396 kWh |
| December | 5.0 | 360 kWh |
| Annual total | 5.7 avg | ~4,600 kWh |
The monsoon trough (July–August) is real but recoverable, October through May delivers strong generation that more than compensates. Annual yield of about 4,600 kWh for 3 kW (about 383 kWh/month, 1,533 kWh/kWp) is excellent by Indian standards.
Choosing the Right Size for Your Ahmedabad Home
The home solar system size guide has the full methodology. For Ahmedabad homes, these rules apply directly:
Bill ₹1,500–₹3,000/month: You are likely in the lower tariff slabs. A 2 kW system covers most of your load. Net cost after subsidy: ₹45,000–₹54,000. Payback: about 2.5 to 3 years at ₹5.75/kWh.
Bill ₹3,000–₹5,000/month: A 3 kW system. Covers 60 to 80% of your consumption. Net cost: ₹79,000–₹94,000. Payback: about 3 to 3.5 years. This is the most popular size for Ahmedabad’s 2 to 3 BHK homeowners.
Bill ₹5,000–₹8,000/month: A 5 kW system. You are in the upper tariff slab where savings per unit are highest. Net cost: ₹1,84,000–₹2,09,000. Payback: about 4 to 5 years.
Bill above ₹8,000/month: A 6 to 10 kW system, subject to your sanctioned load limit. At these bill levels, ROI is strong, roughly ₹7,000–₹8,000/month in savings for a 10 kW system at ₹5.75/kWh.

Yes. Ahmedabad residential consumers of both Torrent Power and UGVCL are eligible for the PM Suryaghar subsidy: ₹30,000 for 1 kW, ₹60,000 for 2 kW, and ₹78,000 for 3 kW and above. After your licensee approves the installation, the subsidy is processed within 15 days and paid to your bank account. You must use a registered vendor from the PM Suryaghar portal vendor list.
How much does a 5 kW solar system cost in Ahmedabad after subsidy?
A 5 kW solar system in Ahmedabad costs ₹2,62,000–₹2,87,000 gross. After the ₹78,000 PM Suryaghar subsidy, net cost is ₹1,84,000–₹2,09,000. The system generates about 630 to 700 kWh per month. At an effective ₹5.75/kWh, annual savings are about ₹43,000–₹48,000, giving a payback of roughly 4 to 5 years.
How many solar panels does a 3 kW Ahmedabad system need?
A 3 kW system typically uses 7 to 8 panels (depending on panel wattage). Using 400W panels: 8 panels = 3,200 Wp. Using 545W panels: 6 panels = 3,270 Wp. Higher-watt panels need less roof space, useful in Ahmedabad’s smaller bungalow terrace plots. The typical roof area required is 200 to 280 sq ft for a 3 kW system in standard flat mounting.
How long does UGVCL net metering take in Ahmedabad?
With a complete application from a registered vendor, feasibility approval usually takes a few weeks, and post-installation inspection and net meter change take a few more. Once your licensee (Torrent Power or UGVCL) approves the installation, the PM Suryaghar subsidy is processed within 15 days. Total timeline from application to subsidy in hand is typically 2 to 3 months with clean documentation. See the PM Suryaghar UGVCL guide for document checklist.
Can Ahmedabad apartment residents get solar?
Individual flat owners in Ahmedabad apartments with separate electricity meters can install individual rooftop systems, subject to building society approval and rooftop access rights. Alternatively, housing societies and RWAs can install a system for common facilities and claim PM Suryaghar support of ₹18,000/kW, up to 500 kW. For high-rise apartments where individual installation is impractical, the group system is typically the better option. Read the solar for housing society guide for the process.
