Industrial Solar Plants for Factories in Jaipur and Rajasthan
Dvaitam works as an industrial solar company in Jaipur, building captive solar plants for factories, processing units and warehouses — on shed roofs, on the ground within the plant boundary, or both. The units an industrial consumer displaces are bought at industrial tariff, typically ₹8–₹10 in Rajasthan, which is why factory solar routinely shows the shortest paybacks of any segment we build for.
It is also the segment where the array is the easy part. What decides whether an industrial plant performs is everything around it: whether the shed purlins take the load, whether the LT panel has room and discipline for the tie-in, whether the transformer has headroom, and whether commissioning is planned around your production schedule or against it. That is engineering work, and it is where we start.
What this service covers
- Load curve before roof area
- Twelve months of consumption data and a look at the actual LT panel come before any capacity number. A plant sized to the roof instead of the load exports cheap units instead of displacing expensive ones.
- Structure treated as a discipline
- Purlin capacity, fixing pull-out strength and wind uplift calculated before mounting is chosen — thin-gauge sheeting on wide purlin spacing is the defining constraint of factory roofs.
- Tie-in around production
- Shutdown windows, isolation plans and changeover sequencing agreed with your plant team in advance, so commissioning costs you hours, not shifts.
Captive solar for Jaipur's industrial belts
Our industrial work concentrates where Jaipur's industry does: Sitapura Industrial Area, VKI Area, Jhotwara and Bindayaka, Bagru's printing and textile belt, Sanganer, and the RIICO estates along the highway corridors — plus the mandi, cold-storage and agro-processing loads in the towns around the district. Being based in Jaipur matters here in a practical way: a survey team can be at a Sitapura shed the same week, and a service call after commissioning does not wait for someone to fly in.
The loads differ — a printing unit's daytime motors, a cold storage's round-the-clock compressors, a textile house's shift pattern — and the design follows the load. What is common is the arithmetic: a factory paying ₹9 a unit with strong daytime consumption is looking at one of the better returns available anywhere in its capital budget.
Cost and payback at industrial tariffs
An industrial rooftop plant between 30 kW and 100 kW in Jaipur costs an indicative ₹13–50 lakh installed and typically pays back in three to four years at industrial tariffs with strong daytime self-consumption — before accelerated depreciation is counted. Every 100 kW generates roughly 1.6 lakh units a year at Jaipur's yield.
The return has three levers. The first is tariff: displacing units at ₹9.50 rather than ₹8 changes annual savings by nearly 20% on the same plant. The second is self-consumption: generation your processes absorb is worth the full tariff, exported generation is worth much less, so shift pattern and load curve set the honest capacity. The third is tax: accelerated depreciation materially improves the post-tax position for a profit-making entity — we supply the generation and cost figures and your finance team models the rest.
PM Surya Ghar does not apply here: it is a residential scheme, and the industrial case has never needed it.
The engineering that decides factory-solar performance
Industrial sites punish design shortcuts more than any other segment, because the electrical environment is harder and the structure was built for a different job.
- Structural verification first: purlin capacity, sheet gauge, fixing pull-out and wind-uplift zones — with reinforcement or layout changes decided on calculation, not optimism
- LT panel condition, spare-way availability, and protection discrimination reviewed before the single line diagram is drawn
- Transformer and sanctioned-load headroom checked against the proposed capacity and the net-metering application it will need
- Power quality considered alongside existing capacitor banks, VFDs and harmonics — a solar inverter joins an electrical conversation already in progress
- Cable routes planned around crane paths, process equipment, hot zones and the expansion you are already planning
- Monitoring at string level, because on a 100 kW array a dead string can hide inside a monthly bill for a year
Shed roof, ground mount, or both
Most factories start on the shed roof because the space is free and the structural case is usually workable. But where roof condition, orientation or area limits the capacity the load justifies, a ground-mounted array inside the plant boundary — over parking, spare yard or unused land — closes the gap. The two are engineered as one plant: one evacuation design, one metering arrangement, one monitoring platform.
For loads beyond what on-site generation can serve, the conversation moves to dedicated captive plants and open-access supply — different metering, different compliance, same discipline. We build those too, and we will tell you honestly when your consumption profile is better served by that route than by filling every roof you own.
Commissioning without stopping production
A factory's real cost of solar is not the EPC price — it is any hour the line stands still. The installation programme is built backwards from that.
Roof and civil work proceed alongside normal operations under agreed access rules. The tie-in and changeover — the only work that genuinely needs the plant off — is compressed into a shutdown window you choose: a weekly off day, a maintenance shutdown, a festival break. Isolation plans, lockout points and restoration sequence are walked through with your electrical team before the day, and testing is documented against commissioning baselines so the plant hands over with proof, not promises.
Frequently asked questions
What is the payback on industrial solar in Jaipur?
Typically three to four years at an industrial tariff near ₹9 a unit with strong daytime self-consumption, before accelerated depreciation is taken into account. Shift pattern and tariff category move it more than anything else — a single-shift unit exports more and pays back slower than a two-shift unit at the same capacity.
How much does a factory solar plant cost?
Indicatively ₹13–50 lakh installed for 30 kW to 100 kW in the Jaipur region, with per-kW cost falling as size rises. Structure drives the spread: a sound shed needing standard clamps sits at the low end; reinforcement, elevated structures or a ground-mounted section move it up. We quote fixed after a structural and electrical survey, not per-kW before one.
Can our shed roof take a solar array?
Usually yes, but it must be proven, not assumed. Thin-gauge sheeting on wide purlin spacing is the defining constraint of factory roofs, and the governing questions are point loading, fixing pull-out strength and wind uplift at edges and corners. We calculate against the actual structure and specify reinforcement where the numbers demand it — walking away from a roof is rare; redesigning the mounting for it is routine.
Will installation interrupt production?
Roof work runs alongside normal operations under agreed access rules. The only work requiring the plant off is the electrical tie-in, which we compress into a shutdown window you choose — typically a weekly off day or maintenance break. The isolation and restoration plan is agreed with your electrical team in writing before the day.
Are industrial units eligible for the PM Surya Ghar subsidy?
No — it is a residential scheme covering domestic connections only. The industrial return rests on displacing ₹8–₹10 units and on accelerated depreciation, which together usually outperform what any subsidy offers a household. Your accountant should model the depreciation side; we provide the generation and cost figures it needs.
Can you also maintain the plant after commissioning?
Yes — under an AMC covering module cleaning matched to your site's soiling rate, string-level monitoring review, annual thermography of every connection, insulation and earth testing against commissioning baselines, and inverter service at manufacturer intervals. Industrial arrays near process exhausts or dusty yards soil faster than any brochure assumes, and the AMC is priced against the site, not a per-kW table.
