The short answer
Rooftop solar in Vapi costs about ₹1.80 lakh to ₹2.25 lakh for 3 kW before subsidy. The ₹78,000 PM Surya Ghar subsidy brings that down to roughly ₹1.02 lakh to ₹1.47 lakh. Each kW generates 4 to 4.5 units a day here. Dakshin Gujarat Vij Company Limited, DGVCL, is the licensee that approves your net meter. Residential payback runs three and a half to five years.

Most Vapi solar pages quote a national average or hide the number behind a callback form. This table answers it outright. Find your monthly bill in the left column, then read across for size, generation, roof area and cost after subsidy.
| Your monthly bill | System | Generates | Roof needed | Cost after subsidy | Payback |
|---|---|---|---|---|---|
| Up to ₹1,800 | 2 kW 1–2 BHK, one AC used sparingly | 240–270units/month | ~200 sq ft | ₹65,000 – ₹95,000 ₹1.25 lakh–₹1.55 lakh before ₹60,000 subsidy | 3.5–4.5 years |
| ₹2,000–₹3,500 | 3 kW Best value The largest system that still earns the full ₹78,000 | 360–405units/month | ~300 sq ft | ₹1.02 lakh – ₹1.47 lakh ₹1.80 lakh–₹2.25 lakh before ₹78,000 subsidy | 3.5–4.5 years |

Indicative Vapi market ranges for 2026, covering Tier-1 modules, a branded inverter, galvanised structure, protection and installation. These are not a Heaven Green Energy quotation. Subsidy amounts are the central PM Surya Ghar figures published on pmsuryaghar.gov.in. Generation assumes a shadow-free, roughly south-facing roof.
Size against units, not rupees. Read the units figure off your DGVCL bill rather than the amount payable, because units are what a solar system cancels. The roof column says shadow-free for a reason. Overhead tanks, lift rooms and a neighbour's parapet all steal output. On the tight plots around Imran Nagar and Chala, an elevated structure usually pays for its extra steel inside two summers.
The 3 kW cliff decides most residential sizing. PM Surya Ghar pays nothing above the third kilowatt, so the subsidy covers a large share of a 3 kW system and a small share of a 10 kW one. If your bill sits on the boundary, 3 kW returns more rupees per rupee spent.
A cheap Vapi quote is cheap in the structure, not the panels. This is a coastal town inside a chemical estate, so galvanising thickness, fastener grade, cable gauge and earthing are not optional line items. Ask every vendor for a written Bill of Materials naming make, model and quantity, and ask specifically what corrosion protection the mounting structure carries. Without that sheet you are comparing two numbers, not two systems.
Roof type changes the price inside every band. A flat RCC terrace in Chala is the cheapest case. A sloped metal shed in GIDC needs different clamps and a purlin check. A terrace four floors up with no lift access adds labour and hoisting that no online calculator knows about. When two Vapi quotes differ by forty thousand rupees on the same system size, the reason usually sits in those three lines rather than in the modules. Ask the surveyor which one applies to your roof and what it added.
There is no rupee saving in that table, deliberately. The rupee figure depends on the tariff slab you personally pay, printed on your own DGVCL bill. It differs between a residential connection in Chala and a commercial one in GIDC. We will not guess it. Bring your last bill to the free survey and we will work the number out with you, in front of you. Any Vapi vendor quoting you a lifetime savings figure before reading your bill has invented it.

PM Surya Ghar Muft Bijli Yojana
Maximum central subsidy for a residential rooftop system.
PM Surya Ghar is a central scheme, so the amount is identical in Vapi, Surat and Delhi. Anyone advertising a bigger "Vapi subsidy" is describing something that does not exist. What changes locally is who processes your file, and here that is DGVCL.
You register at pmsuryaghar.gov.in using your DGVCL consumer number, mobile, Aadhaar and address. We sit with you for this step. A consumer number that does not match DGVCL records is the commonest reason a Vapi application stalls for weeks.
DGVCL checks the application against your sanctioned load and the local network. You then choose an empanelled vendor from the portal list. Heaven Green Energy is empanelled, so we map straight onto your application.
Installation before feasibility clears is how roofs end up generating with no approved net meter. We supply Adani modules with traceable serial numbers and hand you a Bill of Materials and warranty schedule on handover.
DGVCL inspects the installation, fits the bidirectional meter and raises the commissioning certificate on the portal. Our engineer attends the inspection so queries get answered on the spot instead of by letter.
We file the claim once the certificate issues. Government credits the subsidy directly to your bank account. It never passes through us, so treat any Vapi vendor offering to collect the subsidy on your behalf as a warning sign.
PM Surya Ghar covers residential consumers only. A GIDC unit, a shop on NH-48 or a chemical plant in Chanod cannot claim it. Businesses instead claim accelerated depreciation on the asset, which for a taxpaying company frequently returns more than the residential subsidy would have paid. A mixed property, with a shop on the ground floor and the family living above, is judged on the connection category printed on the DGVCL bill. Check that line before assuming either route applies to you.
Net metering is where Vapi pages go wrong most often, because more than one distribution utility operates within fifteen kilometres of this town and the paperwork is not interchangeable.
Vapi is supplied by Dakshin Gujarat Vij Company Limited (DGVCL), the South Gujarat discom. It is a GUVNL subsidiary headquartered in Surat, covering Valsad, Navsari, Surat, Tapi, Bharuch, Narmada and the Dangs. Your file goes to the Valsad circle, through the Vapi division offices that serve the town and the GIDC estate.
That matters because Daman is four kilometres west and Silvassa fifteen kilometres east, and neither is DGVCL territory. Both sit in the Union Territory of Dadra and Nagar Haveli and Daman and Diu, served by the UT's own distribution company and regulated by JERC, not GERC. Vendors who work the whole Vapi to Daman to Silvassa belt routinely quote one process for all three. If your meter is a DGVCL meter, a Daman procedure is the wrong procedure, and a portal application filed against the wrong licensee does not move.
Commercial terms come from the Gujarat Electricity Regulatory Commission (GERC), not from the discom and not from us. Under the GERC framework your system is capped against your sanctioned load, and every consumer category may apply. Surplus units you export are credited against what you draw at night and through the monsoon.
Consumer details, sanctioned load, system rating, single-line diagram and equipment datasheets go to the DGVCL office handling your area.
Filed by usThe discom checks whether your transformer and sanctioned load carry the proposed capacity. Oversized systems fail here, which is why we size against sanctioned load on the first visit.
DGVCLWe install. DGVCL inspects earthing, protection, isolation and metering compliance before anything is energised against the grid.
Us, then DGVCLYour meter is swapped for a bidirectional net meter and the commissioning certificate issues. Export credits begin accruing from that date, not from installation.
DGVCL
Running a factory, warehouse or shop rather than a home? The economics work differently and this page is written for homeowners.
Vapi GIDC is one of India's largest small-scale industrial estates, roughly 1,140 hectares developed from 1967 onwards. It is home to well over a thousand units across chemicals, dyes and intermediates, pharmaceuticals, paper, packaging, plastics and textiles. Shed roofs across GIDC Phase I to Phase IV, Chanod, Morai, Balitha, Salvav and the Sarigam belt carry large shadow-free spans and daytime load profiles. That is close to the ideal case for rooftop solar.
None of those units get PM Surya Ghar. They claim accelerated depreciation on the asset instead, and they can avoid capital outlay altogether through OPEX or RESCO structures.
Industrial payback in Vapi is usually shorter than residential payback, because commercial tariffs are higher and a factory consumes most of what it generates during daylight rather than exporting it. The survey starts with twelve months of your DGVCL demand and consumption data, not with a roof measurement, because sanctioned load and load curve decide what is worth installing.
We have built solar since 2017 and delivered more than 10,000 installations across India, from single terraces to industrial plants running into hundreds of kilowatts.
Heaven Green Energy is headquartered at Mota Varachha, Surat. We serve Vapi and the wider South Gujarat region through our channel partner network and field engineering team. They run the surveys, supervise installation and handle DGVCL coordination on the ground. There is no Heaven Green branch office in Vapi, and we would rather you knew that before you sign than after.
Four steps to a spinning net meter, including the parts that belong to DGVCL rather than to us.
We measure shadow-free area, check the roof structure, read your sanctioned load and twelve months of DGVCL consumption, and log shading from tanks, parapets and neighbouring sheds.
Day 1–2System size, layout, Bill of Materials with makes and models, generation estimate at Vapi irradiance, subsidy and payback. No obligation, and the document is yours to price against rivals.
Day 3–5We file on the national portal and with DGVCL, then install once feasibility clears. A typical residential roof takes two to four days, an industrial shed longer.
Day 5–15DGVCL inspects and fits the bidirectional meter, the commissioning certificate issues, and we file your claim. Government pays the subsidy into your account.
Set by DGVCLA system specified for a dry inland roof is wrong here. Vapi sits near the Arabian Sea coast, takes a heavy four-month monsoon and lives inside a working chemical estate. Three local conditions change the engineering, and a vendor who ignores them quotes you less now and delivers less for twenty-five years.
Vapi receives roughly 1,400 mm of rain a year and almost all of it lands between June and September, with July alone averaging around 469 mm. That means sustained wet loading, waterlogged terraces and wind gusts against the array. Roof penetrations must be sealed and flashed properly, cable entries must drain, and the structure needs real foundation design. Expect a genuine dip in output through July and August, and size on the annual figure.
The sea is close enough that salt-laden air reaches rooftops in Vapi, Daman Road and the western villages. Salt attacks fasteners, clamps and module frames long before it touches the glass. Hot-dip galvanised structures, stainless fixings and properly sealed junction boxes are the difference between an array that lasts twenty-five years and one with rusted clamps by year six. This is the first thing a cut-price quote removes.
Vapi's GIDC estate runs chemical, paper and packaging plants at scale, and particulate fallout settles on glass faster here than in a residential town. Soiling is the most underrated cause of weak output because it is invisible from ground level and shows up only as a slow decline in units. Roofs near the estate want cleaning every two to three weeks through the dry months. Our AMC covers the schedule.
We install across Vapi town, the GIDC estate and the twelve villages merged into the municipal corporation in January 2025. We also cover the wider Valsad industrial belt, down to Sarigam and up to Pardi. An area missing from this list is not an area we refuse, so call and ask.
