Kalol homes, GIDC units and farmhouses get rooftop solar from Heaven Green Energy sized on their own UGVCL units, not on a sales template. We survey the roof, fit Adani panels with a Qbits inverter, lodge the net-metering file with UGVCL's Kalol Division and run the PM Surya Ghar claim for residential connections.
Attach your latest UGVCL bill and say whether the roof is a society terrace, a GIDC shed or a farmhouse slab. You get a size, a generation forecast and the subsidy sum in writing, at no charge.

The short answer
In Kalol, Gandhinagar, a 3 kW rooftop system costs an indicative ₹1.80 lakh to ₹2.25 lakh before subsidy and a 5 kW system ₹2.85 lakh to ₹3.45 lakh. Residential owners recover up to ₹78,000 through PM Surya Ghar after commissioning. Expect 4 to 4.5 units per kW per day. UGVCL, through its Kalol Division, fits the net meter, and a 5 kW home system pays for itself in 4–5 years.

Your bill picks the size. Find the row that matches what you normally pay UGVCL each month. Then read across for the system it suits, the indicative installed price before subsidy, Kalol's expected monthly units, the shade-free roof needed and the likely payback.
| Your monthly bill | System | Generates | Roof needed | Cost after subsidy | Payback |
|---|---|---|---|---|---|
| Up to ₹1,800 | 2 kW A flat or row house in the old Desaivada lanes with fans, a fridge and a cooler | 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 A Panchvati or Kalol West society bungalow claiming the full home subsidy | 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 |
| ₹3,500–₹6,000 | 5 kW A two-storey house off Gandhi Road running two air conditioners in summer | 600–675units/month | ~500 sq ft | ₹2.07 lakh – ₹2.67 lakh ₹2.85 lakh–₹3.45 lakh before ₹78,000 subsidy | 4–5 years |

| Above ₹13,000 | 25 kW+ A daytime workshop or chemical unit in Kalol GIDC or Chhatral GIDC | 3,000–3,400units/month | Site-specific | ₹10.75 lakh – ₹13.50 lakh ₹10.75 lakh–₹13.50 lakh, no subsidy | 3–4.5 years |
These are indicative market ranges for Kalol in 2026, not a Heaven Green Energy quotation. The final price moves with roof type (society RCC terrace, GIDC sheet roof or farmhouse slab), structure height, cable run, chosen hardware and any civil work. Subsidy figures follow the central PM Surya Ghar slabs published at pmsuryaghar.gov.in and apply only to residential connections. Rooftop solar systems attract 5% GST on the equipment since 22 Sep 2025. A supply-and-install contract taxes 30% of the value as installation service at 18%, so the blended rate on a typical quote is about 8.9%.
The subsidy stops growing at three kilowatts. PM Surya Ghar gives ₹30,000 per kW on the first two and ₹18,000 on the third, a ceiling of ₹78,000. A fourth or fifth kilowatt is worth buying only if your own units justify it, never to chase a bigger cheque.
Price gaps between Kalol quotes mostly come from the frame, not the panels. Ask each seller for the steel section, the galvanising thickness and how the legs are fixed to your slab. A frame that skimps on any of these looks fine at handover and starts to rust or loosen after a few summers of dust and pre-monsoon squalls.
GIDC sheds are priced differently again. A sheet roof in Kalol GIDC or Chhatral GIDC usually takes rails clamped to the purlins rather than a raised frame, which cuts steel. Old or corroded sheets have to be replaced first, though. We inspect the sheets and purlins before quoting, so a re-roofing cost does not appear halfway through the job.
No honest installer can print one rupee saving for every Kalol home. Your saving depends on your UGVCL tariff category, the fixed charge for your sanctioned load and how much of your use falls in daylight. A household that commutes to Ahmedabad or Gandhinagar and uses most power after 7 pm exports more by day and banks it under net metering. A family at home all day uses the solar directly. Bring twelve months of bills and we work it out from your actual units. Prefer to work it out yourself first? Put your bill into our solar savings calculator. No phone number required.

PM Surya Ghar Muft Bijli Yojana
Maximum central subsidy for a residential rooftop system.
Kalol households can recover up to ₹78,000 from PM Surya Ghar. You pay the installer in full, and the central government credits the subsidy to your bank after UGVCL commissions the net meter.
Open pmsuryaghar.gov.in, pick Gujarat and UGVCL, and enter the consumer number from your bill. The name and address must match UGVCL's record, so a house still billed in a late parent's name needs a name transfer first.
Enter the capacity you want. UGVCL checks it against your sanctioned load and the transformer feeding your society or village, and replies on the portal, usually inside a fortnight.
Only work by a vendor registered on the portal qualifies. We upload the module and inverter details, installation photos and test results against your application.
UGVCL fits and seals the bidirectional meter and the system passes electrical inspection. The portal then issues the commissioning certificate, which is the trigger for payment.
Upload a cancelled cheque or passbook page for an account in the consumer's name. In Gujarat, claims we file usually reach the bank 30 to 45 days after commissioning.
The subsidy covers residential connections only. Factory units in Kalol GIDC, Chhatral GIDC or Khatraj, along with shops, clinics and agricultural pump connections, cannot claim it. Businesses usually look at accelerated depreciation instead, and farmers at PM-KUSUM for pumps. Have your chartered accountant confirm the tax position before you commit.
Net metering is what makes a home system pay. Units your roof sends to the grid at midday are set off against the units you draw in the evening, so surplus is not wasted.
UGVCL supplies Kalol. Its Kalol Division handles the town and taluka and reports to the Sabarmati Circle. UGVCL's own tender notices for this division name sub-divisions for Kalol Town, Kalol-1, Kalol-2, Santej and Chhatral. Your bill prints the sub-division that holds your connection, and that is where the net-metering file goes.
Buyers here often ask whether they are under Torrent Power, because Gandhinagar and Ahmedabad are so close. Torrent holds the licences for Ahmedabad city and Gandhinagar city, and Kalol is outside both. Santej and Khatraj, the parts of the taluka nearest Ahmedabad, are still UGVCL. One more trap: Gujarat has a second Kalol, in Panchmahal district, which falls under MGVCL. A quote for Kalol, Gandhinagar that mentions MGVCL, DGVCL, PGVCL or Torrent was written for the wrong town.
The GERC framework applies throughout. Rooftop capacity is capped at your sanctioned load, homes, shops, industries and farm connections may all apply, and imports and exports are netted in each billing cycle. Surplus credit left over is settled under whichever GERC order was in force when your system was commissioned.
We file with your consumer number, sanctioned load and the planned capacity, addressed to the Kalol Division sub-division on your bill. That may be Kalol Town, Kalol-1, Kalol-2, Santej or Chhatral.
Heaven GreenOnce fitted, we submit the test report with module and inverter serial numbers, earthing resistance readings and the single-line diagram. Missing pages here are the usual reason meter dates slip.
Heaven GreenUGVCL staff fix and seal the bidirectional meter, and the electrical inspector visits separately. Our engineer attends both visits to answer protection and earthing questions on site.

Heaven Green, then UGVCL
Kalol earns its living from industry. Two GIDC estates, a fertiliser complex and a belt of chemical, pigment and metal units run mostly on day shifts, which is when a rooftop array produces.
GIDC runs two estates in the taluka. The first is Kalol (listed by GIDC as Kalol N.G., North Gujarat, to separate it from Kalol in Panchmahal) on the town's east side. The larger Chhatral estate sits up the Mehsana highway, built out in several phases. Chhatral's units lean towards chemicals, pigments, pharma intermediates, stainless and tube makers, and engineering shops. Khatraj has its own industrial estate post office near Santej, and IFFCO's Kalol fertiliser complex, its first ammonia-urea plant from 1974, stands at Saij. Kalol East grew up around the Sintex plastics works.
For these units the economics turn on daytime use. A reactor, dryer, compressor or CNC line that runs from 9 to 6 absorbs most of what the roof makes, so very little is exported. A two-shift unit that idles on Sundays should be sized from a full year of bills, because Sunday generation is exported and settled at the GERC rate rather than used.
Chemical and pigment plants need extra care with roofs. Acidic or alkaline fumes speed up corrosion of steel structures and sheet fixings. Where the process calls for it, we specify heavier galvanising and stainless fasteners, and we keep inverters in a ventilated electrical room, away from process vents.
Industrial and commercial connections are outside PM Surya Ghar. Read accelerated depreciation on solar for the tax treatment and zero down payment solar if you would rather not tie up working capital.
Agriculture still covers most of the taluka outside these pockets. Gujarat's Jyotigram scheme put farm pumps on separate agricultural feeders, apart from village household supply, and PM Surya Ghar does not pay for pump connections. For a solar pump, see our PM-KUSUM page and the GEDA guide to KUSUM in Gujarat. If your farmhouse in Dingucha, Soja or Nardipur has a separate residential meter, that house can still claim PM Surya Ghar.
Since 2017 we have completed more than 10,000 installations in Gujarat. For you that means UGVCL procedures we file every week, reliable supply of Adani modules and an installer still around when a warranty question comes up.
Heaven Green Energy is headquartered at Mota Varachha, Surat, and that is our only office. We have no shop, branch or local phone number in Kalol. We serve Kalol and the wider North Gujarat region through our channel partner network and field engineering team. They carry out surveys, supervise installation and handle UGVCL coordination on the ground. We state this before you sign rather than after.
From the first call to a UGVCL bill that shows exported units, a Kalol project moves through four stages.
WhatsApp or email two recent UGVCL bills. We look at units consumed and sanctioned load, then give an approximate size and price range before anyone visits.
Same dayAn engineer visits your Kalol property, maps shade from water tanks and neighbouring floors, checks the slab or sheets and plans the cable route. The written proposal gives generation, structure details and the subsidy calculation.
2–4 daysThe team erects the frame, mounts panels, installs the inverter, earthing, surge protection and monitoring, and tests the whole system. Every step is photographed for the portal and the inspector.
2–4 days on siteUGVCL fits the net meter, the inspector clears the system, the portal issues the commissioning certificate and, for a home, the subsidy is credited.
3–7 weeksKalol is hot and dry for most of the year, with a short monsoon from mid-June to mid-September of roughly 800 mm in long-run averages. Strong sun lifts output; heat, dust and early-summer storms are what wear the hardware.
Traffic on the Kalol–Mehsana highway, open plots in the GIDC estates and dry fields after harvest all leave a fine film on glass. It costs units before it is visible. In the dry months, wash every two to three weeks, and more often if the roof faces a busy road or a dusty yard.
Summer afternoons in Kalol regularly pass 40°C, and dark terrace slabs run hotter still. Hot modules lose efficiency, so we raise them on a frame with a clear air gap underneath. We put the inverter in shade or indoors, never on a sun-baked west wall.
Rain cloud costs little output over a full year here because the monsoon is short. The bigger risk is wind: dust storms and thunder squalls in late May and June. We anchor frames into the RCC slab with chemical or expansion anchors, and clamp rails to purlins on GIDC sheds.
