Factory rooftop solar for Jhagadia GIDC.
Process plants in Jhagadia GIDC draw power around the clock, so every unit your roof generates in daylight is used on site. We design plants for chemical-estate conditions, file the DGVCL papers and maintain the system afterwards. Modules come through our role as an authorised channel partner of Adani; inverters are Qbits.

The short answer
Yes, a unit in Jhagadia GIDC can install rooftop solar against its DGVCL connection. Each kilowatt yields 4 to 4.5 units a day, so 250 kW gives roughly 3.65 to 4.1 lakh units a year, nearly all consumed by continuous process loads. Factories get no PM Surya Ghar subsidy but can claim 40% accelerated depreciation. Plants above 25 kW are priced only after a load study.

Jhagadia GIDC, and what its plants ask of a solar system
Jhagadia is a large GIDC estate in Bharuch district, south of the Narmada. For a solar buyer, the useful facts are its scale, its continuous process loads and an atmosphere that is hard on steel.
GIDC's sector-wise estate table places Jhagadia in its Ankleshwar region and Bharuch district. It lists 376 plots across roughly 1,287 hectares and marks the estate as saturated, meaning almost every plot is already allotted. A separate entry, Jhagadia (Kharchi), appears in the same table as an unsaturated estate. Wikipedia describes Jhagadia as a taluka of Bharuch district, about 3 km south of the Narmada's southern bank, and calls the GIDC development there a mega industrial estate.
A saturated estate tells you something useful. Most buildings already exist, some of them for many years, so solar has to fit sheds and RCC roofs that were never drawn with an array in mind. Many plots are also large, so cable runs from roof to main panel can be long.
We do not claim any Jhagadia unit as a client, and GIDC's public table does not list occupiers. Treat an installer's named-client list for the estate with caution unless it comes with documents. This page sticks to the engineering, approvals and tax that apply to any plot you hold here.
Round-the-clock reactors and utilities
Batch and continuous chemical processes run reactors, agitators, vacuum pumps and cooling towers through the night. Solar cannot cover the night load, but your daytime base draw is high enough that a roof-sized plant is almost never exporting. That makes self-consumption close to total and sizing simpler.
Effluent treatment and pumping
ETP blowers, aerators and transfer pumps run continuously and draw a steady, predictable load. Steady loads are the easiest to offset. We read the motor list and running hours at survey, because those figures size the plant more accurately than a monthly bill total.
Chillers, brine and cold storage
Brine chillers and refrigerated stores work hardest on hot afternoons, the hours when the array produces most. In Bharuch summers that overlap is strong. We check compressor starting currents so inverter settings and protection do not trip when large machines start.
Formulation, packing and warehousing
Lighter units that blend, pack or store goods often run a single day shift and close on holidays. Their daytime load can fall below output on some days. We size those plants on the low-load days and confirm the current GERC treatment of surplus units before fixing capacity.
Sizing a Jhagadia plant in units, not rupees
A process plant is sized on daylight units and connection limits. We do not print a rupee saving here, because it depends on your tariff category, demand charges and the share of output you consume.
Daylight units drive the size. On an unshaded Jhagadia roof, each kilowatt produces 4 to 4.5 units a day as a yearly average. A 100 kW array gives about 1.46 to 1.64 lakh units a year, and 250 kW gives about 3.65 to 4.1 lakh. Compare that with what your meter logs in daylight hours. For a continuous chemical unit, the array output usually sits well below daytime use, so almost nothing is exported.
The connection sets the limit. DGVCL approves rooftop capacity against your sanctioned load or contract demand, so roof area alone never fixes the size. Solar cuts the units you buy. It may not cut your recorded maximum demand, because reactors and chillers still peak on a cloudy afternoon or at night. We read twelve months of bills and the demand history first.
Tax replaces the subsidy. PM Surya Ghar covers homes, not factories. Your company can instead claim 40% accelerated depreciation on solar power generating systems under Appendix I of the Income Tax Rules. GST since 22 Sep 2025 is 5% on equipment and 18% on the service share, taken as 30% of a supply-and-install contract, giving roughly 8.9% blended. As a reference, the indicative installed market band at 25 kW is ₹10.75 lakh to ₹13.50 lakh, about ₹43,000 to ₹54,000 per kW. Larger Jhagadia plants are priced after a load study, because coated structure, long cable runs and HT metering change 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.

Engineering for a chemical-estate roof
Jhagadia roofs face corrosive air, monsoon wind and plant safety rules. Three design areas decide whether the array lasts 25 years or rusts in five.
Roof strength and corrosion protection
We check purlins, trusses and sheet condition on sheds, and slab and parapet condition on RCC roofs, then calculate the added load. Near process stacks, acid fumes attack plain galvanising quickly. We specify coating class, stainless fasteners and module mounting for the exposure you actually have, and photograph existing rust before design.
Plant safety, wind and access
Your safety team decides where an array may and may not go. We keep panels away from vents, relief lines, solvent stores and any zone you classify as hazardous, and agree cable routes with you. Fixings go into the structure, every penetration is sealed, and walkways leave room for cleaning and firefighting access.
HT interface and DGVCL documentation
Most large units here take HT supply, so the plant connects on the LT side behind your transformer. We place Qbits inverters near the LT panel, add isolators, surge protection and earthing, and set anti-islanding protection. The single-line diagram and test reports are prepared in the form DGVCL reviews at inspection.
Approvals: who does what.
No plant connects to the grid until DGVCL approves it. We prepare the file, keep drawings consistent with what gets built, and attend each inspection.
Survey, load study and drawings
We read your bills, sanctioned load and supply voltage, survey the roof, and agree exclusion zones with your safety team. The layout and single-line diagram that follow are the documents DGVCL will review.
UsApplication with the licensee
We submit the application with your consumer number, plant rating, diagram and datasheets. DGVCL checks the capacity against your connection and the network, then approves it or asks for revisions.
Us, then DGVCLBuild and safety clearances
We install to the approved drawings, record insulation, earthing and protection tests, and prepare any Electrical Inspectorate file the plant size requires. Your own plant safety permits are followed throughout the work.
UsInspection and energisation
DGVCL inspects the plant and fixes or certifies the metering. Generation counts on your bill from energisation onwards. Our engineer attends the visit so any query is answered on site, not by letter.
DGVCLThree ways to fund the plant.
Three ways to pay. The right one depends on your tax position and on how your board treats capital spending.
Capital purchase
You buy the plant and claim 40% accelerated depreciation from the year it is put to use. This suits a profitable, taxpaying unit that wants to keep every unit generated. An AMC with us covers cleaning schedules, inspections, inverter checks and structure condition, which matters more in corrosive air.
Term loan or equipment finance
A bank or NBFC funds the plant while your company still owns it and claims depreciation. We provide the quotation, bill of materials and unit generation estimate that credit teams ask for. The lender sets rate and tenure, so compare the total cost of each offer, not the EMI alone.
OPEX or RESCO model
A third party builds and owns the plant on your roof, and you pay for units delivered. You spend no capital and claim no depreciation. Check the contract term, buy-out price, roof access rights and what happens if your plant expands or the roof needs repair.
How the project runs.
Five stages from first call to a working plant, each with a document you can check.
Where we work from
Heaven Green Energy's only office is at Mota Varachha, Surat. We do not have a branch in Jhagadia or Bharuch. Surveys, installation supervision and DGVCL inspection visits in the estate are covered by our field engineering team and channel partner network, travelling from Surat. We tell you this before you sign, not after.
Bills and screening call · Day 1
You send twelve months of bills and the plot number. We check supply voltage, sanctioned load and daytime use, and say honestly whether a survey is worth your time.
Site survey under your permits · Week 1
An engineer surveys roofs, structure, rust, shading and cable routes under your work permit system, and inspects the LT panel. Exclusion zones are marked with your safety officer.
Design and written proposal · Week 2
You receive the layout, single-line diagram, bill of materials with makes, coating specification and monthly generation in units. The price follows this design.
Approval and installation · Weeks 3 to 8
We file with DGVCL, procure Adani modules and Qbits inverters, and install in phases around shutdowns and production so roofs stay sealed and lines keep running.
Commissioning and maintenance · After approval
DGVCL inspects and energises the plant. You get test reports, warranties and monitoring access, and the agreed cleaning and inspection schedule begins.

Six things to check with any vendor.
- Jhagadia GIDC lies in Bharuch district, where DGVCL is the distribution licensee; confirm the name on your own bill before applying.
- GIDC lists Jhagadia as a saturated estate of 376 plots in its Ankleshwar region, so most roofs already exist and need checking.
- Each kilowatt yields 4 to 4.5 units a day, so a 250 kW plant gives about 3.65 to 4.1 lakh units a year.
- Continuous process loads mean a Jhagadia plant consumes almost all its own output, which keeps sizing simple.
- Factories claim 40% accelerated depreciation instead of PM Surya Ghar; GST blends to about 8.9% on supply and install.
- Corrosion-rated structure and agreed exclusion zones matter here, and plants above 25 kW are priced after a load study.
