Rooftop solar for foundries and workshops in Shapar–Veraval.
Machining bays, fettling shops and pump assembly lines in Shapar–Veraval draw most of their power in daylight, which is when a rooftop plant produces. We design the plant around your PGVCL connection, supply modules as an authorised channel partner of Adani with Qbits inverters, and file the rooftop papers for you.

The short answer
Factories in the Shapar–Veraval industrial area south of Rajkot are supplied by PGVCL, which runs a Shapar-Veraval sub-division under its Rajkot Rural division. A rooftop plant there yields 4 to 4.5 units per kW a day, so 200 kW gives roughly 2.92 to 3.29 lakh units a year. Factories get no PM Surya Ghar subsidy; they claim 40% accelerated depreciation. Plants above 25 kW are priced after a load study.

Shapar–Veraval: Rajkot's casting and engineering belt
Shapar–Veraval is an industrial area in Rajkot district, south of Rajkot city. It is part of the engineering and foundry belt that grew around the city's diesel engine trade, and its sheds are working buildings first.
First, a clarification that saves confusion. This page is about the Veraval next to Shapar in Rajkot district. It is not Veraval town, the fishing port in Gir Somnath district, which has its own page at /solar/veraval. The two share a name and a licensee, PGVCL, but they sit in different districts. Shapar–Veraval falls under PGVCL's Rajkot Rural circle, while Veraval town is handled by the Veraval division of the Junagadh circle.
Wikipedia's article on Rajkot puts the city's foundry count at about 500 units. It says the cluster grew to supply castings to the local diesel engine industry and spreads across Aji Vasahat, Gondal Road, Bhavnagar Road, Shapar, Veraval and Metoda. Most of those units pour grey iron castings for the domestic market, and a small share export motor and automobile castings. The same article lists bearings, diesel engines, auto parts, forgings and machine tools among Rajkot's industrial products.
We do not name any firm as operating in Shapar–Veraval or as our client there. What matters for solar is your own unit. Three things count: what it draws between morning and late afternoon, how much load PGVCL has sanctioned, and whether the shed roof can carry an array. The rest of this page works through those three questions.
Melting and furnace loads
Induction melting is the heaviest draw in a foundry and often runs in long heats, sometimes past sunset. A rooftop plant rarely covers a furnace on its own. It trims the daytime share, so we size against the melt schedule you actually run rather than the furnace nameplate.
Machining, CNC and tool rooms
Lathes, machining centres and grinders run mainly through the day shift, which is a close fit with the solar curve. Their load is steadier than a furnace, so most of the generation is consumed on site as it is produced. This is usually the easiest load in the belt to offset.
Fettling, shot blasting and compressed air
Shot blasting machines, grinders and the compressors behind pneumatic tools draw hard while castings are cleaned and finished. Compressors in particular run for most of the working day. We log their cycles during the survey, since leaks and idle running change what solar can usefully supply.
Pump, motor and assembly lines
Units that assemble pumps, motors or engine parts often test each piece under power before dispatch. Test benches add short, sharp peaks on top of a modest base load. We look at those peaks so the inverter and protection settings suit the way your floor actually draws power.
Reading the case in units, not rupees
A factory plant earns its keep by replacing grid units your machines use in daylight. We will not print a rupee saving here, because your tariff category, demand charges and day-to-night load split decide it.
Daylight consumption is the number that counts. On a clear Shapar–Veraval roof each kilowatt yields 4 to 4.5 units a day over the year. A 100 kW plant gives about 1.46 to 1.64 lakh units annually; 200 kW gives about 2.92 to 3.29 lakh. Compare that with what your meter records during working daylight hours. A machine shop on one day shift will absorb most of it. A foundry melting through the night will absorb a smaller fraction.
Your PGVCL sanction caps the plant. The licensee approves rooftop capacity against the load sanctioned on your connection, so roof area alone does not set the size. Solar cuts the units you buy; it does not guarantee a lower recorded maximum demand, because a furnace heat during a cloudy spell can still set the peak. Twelve months of bills show us both patterns before we propose a rating.
Tax treatment replaces the household subsidy. PM Surya Ghar covers residential consumers only, so your firm instead claims 40% accelerated depreciation on solar power generating systems under Appendix I of the Income Tax Rules. From 22 Sep 2025, GST is 5% on solar equipment and 18% on the service element, taken as 30% of a supply-and-install contract, which works out to about 8.9% overall. For reference, a 25 kW plant falls in an indicative installed band of ₹10.75 lakh to ₹13.50 lakh, about ₹43,000 to ₹54,000 per kW. Anything bigger is priced after a load study, since structure, cable length 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.

Putting an array on a foundry or workshop shed
Casting and machining sheds raise their own issues: heat, dust, crane gantries and old sheeting. We settle three questions before we draw a layout.
Purlins, sheeting and the extra weight
Many sheds in the belt were built for sheeting and wind only. We record purlin section, spacing and span, the sheet profile and how far it has corroded, then calculate the added load from modules and rails. If a bay is under-strength we specify strengthening or leave it out of the layout before you sign.
Dust, heat vents and safe access
Foundry roofs carry fume vents, ridge monitors and a steady film of sand and dust. We keep arrays clear of hot exhaust, plan cleaning access and walkways, and seal every fixing point against the monsoon. The structure is earthed, and lightning protection is designed for the shed height and layout.
Switchgear, protection and the PGVCL interface
Qbits inverters sit close to the main LT panel to keep AC cable runs short. The drawings show DC and AC isolation, surge protection, earthing pits and the metering PGVCL requires. On an HT connection the plant ties in on the LT side of your transformer, and we document that interface for the licensee.
Approvals: who does what.
PGVCL must approve and inspect your plant before it is connected. We prepare the file, keep it consistent with what gets built, and stand with you at the inspection.
Load study and drawings
We read your bills, connection type and sanctioned load, survey the shed, and produce the plant rating, layout and single-line diagram. PGVCL reviews exactly these documents, so they are checked before filing.
UsRooftop application
We submit the application with your consumer number, plant rating, diagram and equipment datasheets. PGVCL checks it against your sanctioned load and the feeder, then approves it or returns it with queries.
Us, then PGVCLBuild and safety documentation
We install to the approved design and compile test results, earthing readings and protection settings. If your plant size needs Electrical Inspectorate clearance under the current rules, we prepare and follow up that file too.
UsInspection, meters and switch-on
PGVCL inspects the plant and installs or certifies the required meters. After energisation the generation shows on your bill. Our engineer attends the inspection so any query is answered on the spot.
PGVCLThree ways to fund the plant.
You can own the plant, borrow for it, or buy its output. The right choice depends on your tax position and how you treat capital spending.
Buy it outright
Your firm pays for the plant, records it as a fixed asset and claims 40% accelerated depreciation in the year it is first used. This suits a profitable, taxpaying unit. You keep every unit generated, and an AMC with us covers cleaning, inspections and inverter checks.
Bank or NBFC finance
Lenders finance rooftop plants for MSMEs, and you still own the asset and claim depreciation. We provide the quotation, bill of materials and unit-generation estimate a lender asks for. The lender sets the rate and tenure, so compare total cost across offers before choosing.
Third-party ownership (OPEX)
An investor owns the plant on your roof and bills you for the units it supplies. No capital leaves your account, and no depreciation comes to you either. Check tenure, buy-out terms, roof access and what happens if you move premises before you sign.
How the project runs.
Five stages from your first call to a commissioned plant. You see every drawing before it goes to PGVCL.
Where we work from
Heaven Green Energy has a single office, at Mota Varachha in Surat. We do not have an office in Rajkot. Our channel partner network and field engineering team cover Shapar–Veraval and the rest of Saurashtra, running surveys, supervising installation and attending PGVCL inspections. We tell you this before you sign, not after.
Bills and a first read · Day 1
You send twelve months of PGVCL bills and the shed location. We check connection type, sanctioned load and daytime use, and tell you honestly whether a survey is worth your time.
Shed and load survey · Week 1
An engineer measures purlins, sheeting, shading and cable routes, and inspects the main panel. For foundries we note furnace schedules; where needed we log the load for several days.
Design and written proposal · Week 2
You get the layout, single-line diagram, itemised bill of materials and a generation estimate in units. The price comes from this design, not from a per-kW rate card.
Approval and installation · Weeks 3 to 8
We file with PGVCL, procure Adani modules and Qbits inverters, and install in stages so production keeps running and the roof stays sealed.
Commissioning and upkeep · After approval
PGVCL inspects and connects the plant. We hand over test reports and warranties, set up monitoring, and begin the maintenance schedule in your contract.

Six things to check with any vendor.
- Shapar–Veraval is in Rajkot district and supplied by PGVCL through its Shapar-Veraval sub-division, Rajkot Rural division. It is not Veraval town in Gir Somnath.
- A kilowatt of rooftop solar here gives 4 to 4.5 units a day, so a 200 kW plant makes about 2.92 to 3.29 lakh units a year.
- Machining and finishing loads match daylight generation closely; furnace melting usually needs more power than a roof can supply.
- Factories get no PM Surya Ghar subsidy. They claim 40% accelerated depreciation under Appendix I of the Income Tax Rules.
- GST on a turnkey plant blends to about 8.9%: 5% on equipment and 18% on the 30% service share.
- Your sanctioned load caps the plant size, and anything above 25 kW is priced after a load study.
