Rooftop solar for factories in Makarpura GIDC.
Machine shops, fabrication bays and pharma plants in Makarpura GIDC, Vadodara, draw most of their power while the sun is up. A plant on your own shed or terrace covers part of that daytime load directly. We design it, file it with MGVCL and maintain it, using modules as an authorised channel partner of Adani and Qbits inverters.

The short answer
Rooftop solar suits most Makarpura GIDC units because machining, fabrication and pharma HVAC loads peak in daylight. Each kW of panels yields 4 to 4.5 units a day, so 100 kW gives roughly 1.46 to 1.64 lakh units a year. MGVCL is the licensee and approves the grid connection. A 25 kW plant costs about ₹10.75 lakh to ₹13.50 lakh; bigger plants are priced after a load study.

What Makarpura's factories actually run on
Makarpura is the GIDC estate inside Vadodara's own city limits. Its units are mostly engineering and pharmaceutical, and both kinds buy their heaviest electricity during working daylight hours, which is when a rooftop plant produces.
Makarpura sits on the southern side of Vadodara, between the Mumbai rail line and the residential belt of Tarsali and Manjalpur. Wikipedia's article on the area describes it as an important industrial district of the city with a GIDC estate, and places the Vadodara Chamber of Commerce and Industry there. That article carries an unreferenced tag, so treat it as a pointer rather than proof. Makarpura railway station sits on the Western Railway main line, and the Western Dedicated Freight Corridor lists Makarpura among its stations in Gujarat.
The Vadodara district administration's site names engineering, machine tools, pharmaceuticals, chemicals and glass among the district's industries. It also says Vadodara hosts a large share of India's power transmission and distribution equipment makers, along with hundreds of ancillary suppliers. Plenty of those ancillary shops are small: a CNC line, a press, a paint booth, a test bench.
We could not open GIDC's own estate record for Makarpura, so this page states no founding year, plot count or area. We also name no company. What matters for solar is your connection, your roof and the shape of your daytime load, and we measure those on site.
Machine shops and CNC lines
Lathes, machining centres, grinders and the compressors behind them run through the day shift and stop at night. That pattern lines up with solar output almost hour for hour, so a correctly sized plant feeds most of its units straight into the shop floor instead of the grid.
Fabrication, welding and heat treatment
Welding sets, shot blasting and electric furnaces draw heavy, uneven current. Solar does not smooth those spikes, and your demand charge still follows the peak. What solar does is shave the steady base underneath them, which is why we log the load before choosing a size.
Pharma HVAC, chillers and purified water
Clean rooms, air handling units and water systems often run around the clock. Solar covers the daytime share of that base load and leaves the night share on the grid. Units with a near-flat profile usually get the cleanest match between plant size and consumption.
Electrical equipment assembly and testing
Units building or testing transformers, switchgear and panels can draw short, high test loads. We separate those events from the everyday load when we read your logger data. That way we size the plant to what the factory uses daily, not to its busiest test hour.
How the numbers work for a Makarpura unit
Count units, not rupees. A rooftop plant offsets daytime units you would otherwise buy from MGVCL, and the value of each unit depends on your own tariff category, which only your bill shows.
Start from units. Each kW of panels on an unshaded Vadodara roof produces about 4 to 4.5 units a day across the year. A 50 kW plant therefore makes 200 to 225 units on an average day, and a 100 kW plant 400 to 450. Compare that against the units your factory draws between nine and five, not against the monthly total. If a weekly shutdown or a second shift changes the picture, the logger will show it.
Demand and sanctioned load are separate questions. Solar lowers the units you import, but your contract demand and any demand charge follow your peak, and a cloud or a furnace start can still set that peak. We read both off your bill and keep them apart in the proposal. Where a plant would push generation well beyond your daytime use, we size it down rather than promise a credit we have not verified for your connection.
Tax shapes the effective cost. A profitable firm that owns the plant can claim 40% accelerated depreciation on solar power generating systems in the year it is put to use. Our guide to accelerated depreciation on solar explains the mechanics. Since 22 Sep 2025, solar equipment carries 5% GST and the service share of a turnkey contract, taken as 30%, carries 18%, which works out to about 8.9% overall. As a reference point, a 25 kW plant runs about ₹10.75 lakh to ₹13.50 lakh, roughly ₹43,000 to ₹54,000 per kW. Larger plants are priced only after the load study and roof check.
| 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 checks on a Makarpura roof
Older sheds and RCC terraces both carry solar, but on different terms. We settle three things before quoting: load capacity, wind and fire safety, and the electrical tie-in with MGVCL.
Sheet, purlin and slab capacity
Many estate buildings have been extended or re-roofed more than once, so the drawings rarely match the shed. We measure purlin sections and spacing, note corroded or patched sheets, and check RCC slabs for waterproofing. If the structure needs stiffening or new sheeting, you hear that in the proposal before money changes hands.
Wind load, fixing and fire access
Vadodara's pre-monsoon storms test every fixing. Rails go into purlins with sealed penetrations, and the layout leaves clear routes for cleaning, for fire crews and around ridge vents, exhaust fans and skylights. Roofs above paint booths, furnaces or solvent stores get extra spacing, and the array is earthed and lightning-protected.
Switchgear, metering and the MGVCL tie-in
Qbits inverters sit close to your main LT panel to keep cable runs short. The single-line diagram shows DC and AC isolation, surge protection, earthing and metering. For HT consumers the plant joins on the LT side of your transformer, and MGVCL publishes a separate document list for HT rooftop agreements, which we follow.
Approvals: who does what.
No rooftop plant runs in parallel with MGVCL's network without the licensee's approval and inspection. We prepare and follow the file, and you sign each form after reading it.
Load data, survey and drawings
We collect a year of bills, your sanctioned load and supply voltage, then survey the roof and fit a logger if needed. The layout and single-line diagram come from that data, and we check consumer details against the bill before anything is filed.
UsFiling with MGVCL
The application carries your consumer number, plant size, diagram and equipment details. MGVCL's solar rooftop page lists the forms and undertakings it expects, including an undertaking on the CEI drawing. The licensee reviews the file and approves it or returns queries.
Us, then MGVCLBuild and test records
We install to the approved drawing, then record earthing resistance, insulation tests and inverter protection settings. Where the plant size or your connection needs the Chief Electrical Inspector's clearance, we prepare that drawing and submission and track it until it closes.
UsInspection, metering and switch-on
MGVCL engineers inspect the plant and install or test the generation and import-export meters. Once they sign off, the plant is energised and its units start appearing on your bill. Our engineer attends the inspection to answer technical questions on the spot.
MGVCLThree ways to fund the plant.
The right way to pay depends on whether your firm pays tax, how it treats capital spending and how long it expects to stay on the plot.
Buy the plant from cash
Owning the plant outright gives you every unit it makes and the 40% depreciation claim in the year of use. It suits a taxpaying unit that owns its plot or holds a long lease. Our annual maintenance contract then covers cleaning schedules, inspections, inverter health and generation reviews.
Term loan or equipment finance
Banks and NBFCs finance rooftop plants for MSMEs, and you still own the asset and claim depreciation. We provide the quotation, bill of materials and a generation estimate in the form lenders ask for. Rate and tenure are the lender's decision, so compare the full cost of each offer.
Third-party ownership (OPEX)
A developer owns the plant on your roof and charges you for the units it produces. You spend no capital but give up the depreciation claim. Read tenure, exit and buy-out clauses and roof-access terms closely, and check how the contract handles a sale or relocation of your unit.
How the project runs.
Five stages take a Makarpura plant from first call to grid connection. Durations vary with plant size and MGVCL's queue.
Where we work from
Heaven Green Energy's only office is at Mota Varachha in Surat; we have no branch in Vadodara. Makarpura projects are surveyed, supervised and taken through MGVCL by our field engineering team and channel partner network in Central Gujarat. We tell you who will be on your roof before you sign, not after.
Bills and first call · Day 1 to 2
You share twelve months of MGVCL bills and basic plot details. We flag any obvious blockers, such as shading, roof condition or a connection change, before arranging a visit.
Survey and load logging · About 1 week
An engineer inspects the roof, panels and transformer, then logs your load where bills alone cannot show the daytime pattern. Shift timings and planned expansions go into the brief.
Design and proposal · About 1 week
You receive the layout, single-line diagram, bill of materials, expected units and a firm price. We explain each line and change the design if your plans change.
MGVCL approval and build · Depends on file
We file with MGVCL and build once approval arrives. Installation is planned around your shifts so machines keep running and roof work stays away from loading bays.
Inspection and handover · After MGVCL visit
MGVCL inspects and meters the plant. We hand over test records, warranties and monitoring access, and the maintenance schedule starts from the switch-on date.

Six things to check with any vendor.
- Makarpura GIDC lies inside Vadodara city, and MGVCL is the licensee, not Torrent Power.
- Engineering and pharma loads run mostly in daylight, which suits rooftop solar well.
- Each kW yields 4 to 4.5 units a day, so 100 kW gives about 1.46 to 1.64 lakh units a year.
- Solar cuts imported units; demand charges still follow your peak, so size on logged load.
- Owners can claim 40% accelerated depreciation, and turnkey GST works out near 8.9%.
- Plants above 25 kW are priced only after a load study and a roof check.
