Engineering, procurement and construction under one accountable contract - and the approvals that decide your project timeline.

Industrial buyers ask a different question from homeowners. Not "how much will I save" but "who is accountable when something goes wrong at 2 am in the middle of a production run".
That is what industrial solar EPC in Chhattisgarh is about: a single contract, a single accountable party, and a plant engineered to sit alongside production equipment for twenty-five years.
The term EPC gets used loosely by firms that are really just installers. A genuine turnkey scope covers all of this:
If a quotation leaves approvals to you, it is not a turnkey contract regardless of what the cover page says.
| Plant Size | Design & Approvals | Construction | Total |
|---|---|---|---|
| 50 - 100 kW | 4 - 6 weeks | 2 - 3 weeks | 8 - 10 weeks |
| 100 - 250 kW | 5 - 8 weeks | 3 - 5 weeks | 10 - 14 weeks |
| 250 - 500 kW | 6 - 10 weeks | 5 - 7 weeks | 12 - 16 weeks |
| 500 kW - 1 MW | 8 - 12 weeks | 8 - 12 weeks | 18 - 26 weeks |
Notice that approvals take longer than construction on smaller plants. Any EPC contractor promising a 500 kW plant in six weeks is either ignoring CEIG or has not read the site conditions.
| Factor | CAPEX (you own) | OPEX / RESCO (developer owns) |
|---|---|---|
| Upfront capital | Full project cost | Nil |
| Accelerated depreciation | Yours, 40% year one | Developer's |
| Electricity cost after | Effectively nil | Agreed tariff, usually escalating |
| Maintenance responsibility | Yours, or via AMC | Developer's |
| 25-year financial return | Substantially higher | Lower but risk-free |
| Suits | Profitable firms with capital | Capital-constrained or short-tenure premises |
For most established manufacturers in Urla and Siltara with taxable profits, CAPEX wins clearly because the depreciation benefit is substantial and the asset is theirs. The tax treatment is set out in our subsidy and finance guide.
Most Raipur-region industrial sheds are metal sheet or asbestos on steel purlins, and each brings its own constraints.
Our guide to choosing a solar EPC company in Chhattisgarh goes into the due-diligence checklist in more detail.
EPC stands for Engineering, Procurement and Construction. Under a turnkey EPC contract one company carries responsibility for design, equipment supply, civil and electrical works, approvals, commissioning and handover - so there is a single point of accountability rather than three contractors blaming each other.
For a 100 kW to 500 kW captive plant, typically 10 to 16 weeks from contract to commissioning. Construction is only part of that; CSPDCL approvals and CEIG clearance usually govern the critical path.
Yes, generally for installations above 650 V or where statutory inspection applies under the Electricity Rules. The Chief Electrical Inspector to Government reviews drawings, protection and earthing before energisation. We prepare and file this as part of the EPC scope.
Under CAPEX you own the plant, claim 40 per cent accelerated depreciation and keep all the savings. Under OPEX or RESCO a developer funds and owns it and you buy the power at an agreed tariff. CAPEX gives better long-run returns; OPEX needs no capital.
Not from rooftop solar alone. Rooftop capacity is limited by roof area and solar only generates in daylight, so a typical factory offsets 20 to 40 per cent of annual consumption. Full replacement needs open access or ground-mounted capacity with storage.
An industrial solar plant is a twenty-five-year asset bolted to your production facility. It deserves a contractor who will still be reachable in year twelve. We have been delivering solar across Chhattisgarh since 2010, from a fixed office in Raipur.
