Rooftop solar for workshops and units in Hazira.
The big plants at Hazira run their own power. This page is for everyone else: fabrication shops, machine shops, warehouses and contractor yards that buy grid power from DGVCL. We are an authorised channel partner of Adani for modules, use Qbits inverters, and build structures for salt air from day one.

The short answer
Small and mid-size units in the Hazira belt of Surat can put solar on their own shed or warehouse roofs and cut the daytime units they buy from DGVCL. A kilowatt here yields 4 to 4.5 units a day, so 50 kW gives roughly 73,000 to 82,000 units a year. Factories get no PM Surya Ghar subsidy; they claim 40% accelerated depreciation. Salt air makes the structure specification the deciding cost item.

Hazira beyond the big plants
Hazira is a port and heavy-industry zone on the Tapi estuary, west of Surat. Around the large complexes sits a ring of smaller businesses that buy grid power, and those are the roofs this page is about.
Wikipedia describes Hazira as a suburb and transshipment port of Surat, on the Tapi about 8 km from the Arabian Sea and roughly 22 km from the city centre. The port handles liquefied natural gas and mixed cargo, and the belt also carries shipbuilding, heavy engineering, petrochemical, cement and power plants. Those complexes mostly generate or contract their own electricity, so a rooftop installer has little to offer them.
The opportunity is in the supply chain. Heavy plants need fabricators, machine shops, crane and equipment hirers, transporters, warehouses and maintenance contractors, and many of these work from sheds along the Hazira road and around Ichchhapore. These businesses pay a DGVCL bill like any other commercial or industrial consumer. The Surat district website lists a DGVCL sub-division office at Ichchhapore, inside the 66 kV substation compound at GETCO Colony, which is the side of the city that faces Hazira.
We do not name any company as a client in Hazira, and we will not list who operates there. An installer that drops famous Hazira names into a sales pitch is borrowing credibility it has not earned. Judge us on the survey report instead.
Fabrication and welding shops
Welding sets, plasma and gas cutting, grinders and overhead cranes draw heavily through the day shift. That daytime pattern lines up with generation. The catch is welding load: it is spiky, so we size the plant on average daytime units and leave peaks to the grid.
Machine shops and repair bays
Lathes, milling and boring machines, compressors and test benches run steadily while orders are open. Repair work for the larger plants can be irregular, with busy shutdown seasons and quiet weeks. We read twelve months of bills so the plant is sized on a normal month, not a shutdown spike.
Warehouses, cold rooms and logistics yards
Port-linked storage has large flat or gently pitched roofs and modest load: lighting, forklifts on charge, office cooling and sometimes chilled rooms. Roof area often exceeds what the load can use. Here the sanctioned load and current GERC banking terms, not the roof, set the plant size.
Contractor offices and site camps
Contractors who hold long maintenance contracts often run permanent offices, stores and canteens near the gates. A small plant on those buildings covers fans, cooling and computers. Temporary camps are a poor fit, because a plant should stay where it is for its full working life.
Reading the numbers in units, not rupees
We size a Hazira plant on the units your meter records in daylight. We do not print a rupee saving here, because that depends on your tariff category, your demand charges and how much output you use on site.
Daylight units come first. On a clear, unshaded roof each kilowatt yields 4 to 4.5 units a day across the year. So 50 kW produces about 73,000 to 82,000 units annually, and 100 kW about 1.46 to 1.64 lakh. Compare that with what your unit draws between mid-morning and late afternoon. Output used the moment it is made is worth the most to you.
Your connection caps the plant. DGVCL weighs a rooftop request against your sanctioned load and the local feeder, so a big warehouse roof does not mean a big plant. Solar trims units but may not trim your recorded maximum demand, since a passing cloud or an evening welding job still pulls full power from the grid. Coastal haze and the monsoon also lower output in some months, which our monthly estimate shows.
Tax replaces the subsidy. PM Surya Ghar pays only residential consumers. A business claims 40% accelerated depreciation on solar power generating systems under Appendix I of the Income Tax Rules. Since 22 Sep 2025, solar equipment carries 5% GST and the service share, taken as 30% of a supply-and-install contract, carries 18%, which blends to about 8.9%. For a 25 kW plant the indicative Gujarat market band is ₹10.75 lakh to ₹13.50 lakh, about ₹43,000 to ₹54,000 per kW. Bigger plants are priced after a load study, because coastal-grade steel, cable distance and metering move the cost.
| Plant size | Units a year |
|---|---|
| 25 kW | 36,500 – 41,063 |
| 50 kW | 73,000 – 82,125 |
| 100 kW | 1,46,000 – 1,64,250 |
| 250 kW | 3,65,000 – 4,10,625 |
| 500 kW | 7,30,000 – 8,21,250 |
Indicative installed cost at 25 kW: ₹10.75–13.50 lakh (market range, not a quotation). Larger plants are priced after a load study of your bills and roof.

Building for salt air and port sheds
Hazira is the most corrosive setting we work in around Surat. Three things get settled before a panel is ordered: the roof, the steel and fixings, and the electrical connection.
Shed condition and load capacity
Many Hazira sheds are long-span steel frames with metal sheeting that has already seen years of salt and industrial dust. We check purlin sections, spacing, rust at laps and fixing points, and the remaining life of the sheet. If the sheet will fail before the panels do, we say replace it first.
Coastal steel, fasteners and wind
Mounting rails and brackets need a heavier corrosion specification here than inland, with stainless or suitably coated fasteners and sealed penetrations. Wind off the sea is designed for at the roof edges. Panel washing is planned more often, because salt and dust films cut output. Read our <a href="/blog/solar-in-coastal-salt-mist">salt-mist guide</a>.
Inverters, earthing and the DGVCL connection
Qbits inverters sit in a ventilated, covered spot near the main panel, away from direct spray. The design carries DC and AC isolation, surge protection, earthing pits and the meter arrangement DGVCL asks for. On an HT supply the plant ties in on the LT side, and we draw that interface for inspection.
Approvals: who does what.
No plant connects to the grid until DGVCL approves it. Files move faster when the drawings match the roof exactly, so we prepare them and stand beside you at inspection.
Bill review and site survey
We read your bills, connection type and sanctioned load, then walk the roof and switch room. The result is a plant size, layout and single-line diagram that the licensee can check against your connection.
UsApplication to the licensee
The file carries your consumer number, plant rating, diagram and datasheets for modules and inverters. DGVCL tests it against your sanctioned load and the feeder, then approves or asks for changes.
Us, then DGVCLBuild and safety paperwork
We install to the approved drawing and record insulation tests, earthing values and protection settings. If your plant size needs an Electrical Inspectorate clearance, we prepare that file and follow it up.
UsInspection and meter
The licensee inspects the plant and installs or certifies the metering. Generation counts on your bill only after the connection is energised. Our engineer attends so any query is answered on the spot.
DGVCLThree ways to fund the plant.
Pick a payment route by your tax position and how long you expect to stay at the site. A contractor on a short lease has different needs from an owner-occupier.
Buy the plant outright
Your firm owns the asset and claims 40% accelerated depreciation in the year it is first used. This suits a profitable, taxpaying business that owns its shed or holds a long lease. You keep every unit generated, and our AMC covers cleaning, inspections and inverter checks.
Term loan or equipment finance
Banks and NBFCs lend to MSMEs for solar, and you still own the plant for depreciation. We provide the quotation, bill of materials and unit estimate lenders request. The lender sets rate and tenure, so compare total cost across offers, not just the monthly instalment.
Third-party ownership (OPEX)
An investor owns the plant on your roof and bills you for units delivered. You spend no capital, and you give up depreciation. On a rented Hazira shed, check that the landlord agrees and that the contract covers relocation, buy-out and what happens if you leave early.
How the project runs.
Five steps from the first bill to a running plant. You see every drawing before it goes to DGVCL.
Where we work from
Heaven Green Energy runs from a single office at Mota Varachha in Surat, roughly 22 km and one city crossing away from Hazira. Our own engineers carry out the survey, supervise the build and attend the DGVCL inspection, so there is no outside partner between you and the team that designed the plant.
Bills and a first call · Day 1
Share a year of bills and where the shed or yard sits. We look at tariff category, sanctioned load and daytime use, and tell you honestly if the site is worth a visit.
Survey of roof and switch room · Week 1
An engineer measures the roof, checks purlins and corrosion, notes shading from cranes, tanks or stacks, and inspects the main panel. Where loads vary, we can log them for a few days.
Design and written proposal · Week 2
You get the layout, single-line diagram, bill of materials with makes and quantities, and a month-by-month unit estimate. The price comes from that design, never from a per-kW rate card.
Licensee filing and build · Weeks 3 to 8
We file with DGVCL, procure Adani modules and Qbits inverters, and schedule roof work around your jobs. Work faces are closed off daily so the shed stays dry and production continues.
Connection and upkeep · After approval
DGVCL inspects and connects the plant. We hand over test records and warranties, switch on monitoring, and start a cleaning and inspection schedule set for coastal conditions.
What businesses say after a year.
Plants we have built for businesses, each labelled with the city where it stands. None is in Hazira, and we will not pretend one is.

150 kW at our textile factory dropped power costs by 68%. The ROI calculation they provided was spot-on, break-even under 4 years.
Commercial · Surat · 150 kW
80 kW on our hospital rooftop. Diesel backup running time cut by 60%. Heaven Green's structural design cleared all wind-load checks first time.
Commercial · Anand · 80 kW
Six things to check with any vendor.
- Smaller units around Hazira buy power from DGVCL; check your bill, because some large complexes run captive or separate supply arrangements.
- A kilowatt yields 4 to 4.5 units a day here, so a 50 kW plant makes about 73,000 to 82,000 units a year.
- Businesses do not get the PM Surya Ghar subsidy. They claim 40% accelerated depreciation instead.
- Salt air drives the structure specification: coated or stainless fixings, heavier corrosion protection and more frequent washing.
- Sanctioned load and daytime use set the plant size, so a large warehouse roof may carry a modest plant.
- Only plants up to about 25 kW have an indicative market band; anything larger is priced after a load study.
