A petrol pump is one of the most overlooked solar opportunities in Indian commercial real estate. Every HP (Hindustan Petroleum), IOC (Indian Oil Corporation), BPCL (Bharat Petroleum Corporation Limited), and Reliance retail outlet runs 24/7 — dispensers, canopy lighting, ATM kiosks, air compressors, and the attached convenience shop pull a constant 30–60 kW load through commercial tariffs of ₹8–₹12/kWh. The canopy itself, typically 4,000–6,000 sqft of unshaded south-facing structure, is a free mounting surface most operators ignore. In 2026, with the three OMCs (Oil Marketing Companies) pushing dealer outlets toward 100% solarisation by 2027 and PESO (Petroleum and Explosives Safety Organisation) clearance routines now standardised, a 50 kW system pays back in 4.5–5 years after Accelerated Depreciation.
This guide is for the dealer or operator running an HP, IOC, BPCL, or Reliance pump and asking three questions — how much solar will the OMC let me put up, what does PESO require around the dispenser hazardous zones, and what does the post-AD payback actually look like on a 25, 50, or 100 kW system.
Direct answer. A 50 kW solar plant on a typical Indian petrol pump canopy costs ₹28–32 lakh, generates 75,000–82,000 kWh per year, and saves ₹4.5–5 lakh annually at a ₹9/kWh commercial tariff. With Accelerated Depreciation (AD) at 40% in Year 1, post-tax payback lands at 4.5–5 years. The non-negotiable step is PESO clearance — solar PV is barred from Zone 0 and Zone 1 (within 3 metres of the dispenser nozzle) under the Petroleum Rules 2002, conditional in Zone 2 (3–7 m), and unrestricted beyond 7 m. OMC approval from HP, IOC, BPCL, or Reliance runs in parallel and takes 30–60 days.
If you’re at the point of comparing dealer-development quotes or trying to fit a 50 kW system onto a canopy with PESO breathing down your neck, this is the path our deployment team uses across the 100+ HP, IOC, and BPCL pumps Heaven Green Energy has solarised since 2022.
Why Petrol Pumps Are Ideal Solar Candidates
Three structural features make petrol stations one of the highest-yield commercial solar verticals in India.
The load is 24/7 and daytime-heavy. Dispensers, air compressors, canopy lights (which run dusk-to-dawn but are dwarfed by daytime AC load), and the attached shop/ATM together pull 30–60 kW continuously. Roughly 55–60% of that load falls within solar hours (8 am to 6 pm), which means a properly sized system self-consumes nearly everything it produces — no dependence on poor commercial export tariffs.
The canopy is purpose-built for solar. A standard MS (Mild Steel) canopy at an Indian retail outlet is 18–24 m long, 12–15 m deep, and structurally rated for live loads well above the 15–18 kg/sqm that crystalline panels impose. It’s south-facing by design (dispensers under a south-facing canopy maximise shade), unshaded, and at a height that defeats theft. A 5,000 sqft canopy supports 40–50 kWp comfortably.
The tariff differential is large. Commercial connections at petrol pumps are billed at ₹8–₹12/kWh depending on state — the highest slab in most Indian DISCOMs (Distribution Companies). Every solar unit self-consumed displaces that tariff. Compare with residential at ₹4–₹7/kWh, where the savings per kWh are 40% lower.
Petrol Pump Load Profile — Typical 24-Hour Breakdown
| Equipment | Connected Load | Daily Hours | Daily kWh |
|---|---|---|---|
| Dispensers (4 nozzles × 2.2 kW) | 8.8 kW | 18 (intermittent) | 60–80 |
| Canopy lighting (LED + halogen) | 6–8 kW | 12 | 80–95 |
| Air compressor (tyre inflation) | 5 kW | 6 (cycled) | 22–28 |
| Convenience shop + ATM | 4–6 kW | 24 | 95–110 |
| Office AC + computer + biometric | 3.5 kW | 12 | 38–42 |
| Submersible water pump | 1.5 kW | 4 | 5–7 |
| Forecourt CCTV + signage | 1 kW | 24 | 22–24 |
| Total — typical pump | ~30–35 kW | — | ~330–390 kWh/day |
A site doing the average ~360 kWh/day consumes ~131,000 kWh/year. A 50 kW solar plant generates 75,000–82,000 kWh/year in most Indian climatic zones — covering 57–63% of the annual load without exporting a single unit.
The 5-Stage Petrol Pump Solar Implementation Path
This is the framework Heaven Green Energy uses across HP, IOC, BPCL, and Reliance retail outlets. Five stages — each with a separate approval chain. Skipping a stage (especially OMC engineering NOC before PESO) creates rework cycles that add 45–60 days.
Stage 1: OMC Engineering NOC (Day 0–25)
The dealer cannot put solar on a branded canopy without written engineering clearance from the OMC. HP, IOC, BPCL, and Reliance each maintain a Retail Engineering & Projects (RE&P) cell that signs off on three things — structural impact on the canopy, electrical interface with the existing LT (Low Tension) panel, and branding/visibility of OMC signage post-installation.
Submit through the regional OMC office: structural load calculation for the canopy, single-line electrical diagram showing solar tie-in at the LT panel, panel layout drawing preserving brand-mandated signage zones, and the EPC contractor’s credentials. HP and BPCL typically respond in 15–25 days; IOC and Reliance run 20–30 days.
Stage 2: PESO / Chief Controller of Explosives Clearance (Day 10–55)
The petrol pump operates under a PESO licence (Form XIV under the Petroleum Rules 2002). Any electrical addition in the licensed premises requires a fresh PESO clearance. The application goes to the regional Joint Chief Controller of Explosives office with the OMC-approved layout, the hazardous zone classification drawing (Zone 0/1/2 demarcation), and the contractor’s PESO-recognised credentials.
Read the solar fire safety protocols guide before you draft the PESO submission — the dossier needs intrinsically safe wiring callouts and a fire-suppression interface that PESO inspectors flag for in 80% of first submissions. PESO clearance typically takes 30–45 days from a clean submission. Filing in parallel with OMC NOC is the standard sequence.
Stage 3: System Sizing & DISCOM Approval (Day 30–55)
Once OMC and PESO are in motion, finalise system capacity against your sanctioned load and the canopy area available outside Zone 1 boundaries. The standard sizing decision is 25 kW (canopy-only, conservative), 50 kW (canopy maximum), or 100 kW (canopy + ground mount on adjoining land). Net metering or net billing applications go to the local DISCOM; commercial connections above 25 kW typically require additional CEIG (Chief Electrical Inspector to Government) clearance under CEA safety regulations.
Stage 4: Installation (Day 55–75)
Installation on a live petrol pump is constrained — hot-work permits, no welding within Zone 1/2, no overhead lifting during pump operating hours at high-traffic outlets. A 50 kW canopy install runs 8–12 working days with night-shift wiring on busy sites. Earthing must meet IS 3043 standards with a dedicated solar earth pit separate from the existing canopy lighting earth — see the solar grounding and earthing guide for the specific resistance targets.
Stage 5: Commissioning, OMC Audit, PESO Witness (Day 75–95)
The final stage triggers three sign-offs in sequence — DISCOM net meter inspection, OMC engineering audit (HP/IOC/BPCL/Reliance send their RE&P engineer for as-built verification), and PESO witness commissioning where the regional inspector physically inspects the AC/DC isolators, intrinsically safe wiring in Zone 2, and the fire interlock. Only after all three is the system formally cleared for revenue operation.
Hazardous Zone Compliance — PESO Zone 1/2 Distance Rules
This is the single most misunderstood part of petrol pump solar. Under the Petroleum Rules 2002 read with PESO’s Hazardous Area Classification guidelines, every petrol dispensing premises is divided into hazardous zones based on the probability of an explosive vapour atmosphere.
| Zone | Definition | Typical Boundary | Solar PV Allowed? |
|---|---|---|---|
| Zone 0 | Continuous explosive atmosphere (inside fuel tank) | Inside underground tank | No — no electrical equipment of any kind |
| Zone 1 | Likely explosive atmosphere during normal operation | Within 3 m radius of dispenser nozzle; within 1.5 m of vent pipe outlet | No solar PV; only intrinsically safe (Ex i) equipment |
| Zone 2 | Unlikely explosive atmosphere; only abnormal | 3 m to 7 m from dispenser; 1.5 m to 4.5 m from vent | Conditional — Ex e / Ex d rated, intrinsically safe wiring, no exposed DC at busbar level |
| Non-hazardous | Beyond Zone 2 boundary | Beyond 7 m from dispenser; beyond 4.5 m from vent | Standard solar PV permitted |
What this means for canopy mounting. The dispenser island sits in Zone 1, but the canopy roof above it is typically 4.5–5.5 m above ground — putting the canopy roof surface in Zone 2 directly above the dispenser, and non-hazardous beyond a 7 m horizontal arc. Solar panels on the canopy are permissible because the panel surface itself sits in Zone 2 or beyond, but the DC string wiring must be routed through metallic conduit, all junction boxes must be IP65-rated and certified flameproof (Ex d) within Zone 2, and string monitoring devices cannot be mounted within the 7 m arc.
The inverter must be located at least 7 m from any dispenser nozzle and 4.5 m from any vent pipe — typically wall-mounted on the convenience shop or in a dedicated electrical room. AC and DC isolators on the canopy must be Ex e rated within Zone 2. For the lightning protection design that PESO inspectors specifically check, refer to the solar lightning protection guide — a separate down-conductor system to a dedicated lightning earth is non-negotiable on petrol stations.
⚠️ Critical safety note
Do not allow any contractor to route exposed DC cabling across a dispenser island, drill into the canopy soffit directly above a dispenser, or run AC wiring without flameproof glands within Zone 2. A single PESO non-compliance can suspend the petroleum licence for the entire pump — losing 40–80 days of fuel sales while the violation is rectified. This is a multi-crore exposure for a saving of a few thousand rupees in installation cost.
25 kW vs 50 kW vs 100 kW Sizing
The three standard sizing tiers map cleanly to canopy area, sanctioned load, and dealer ambition.
| Parameter | 25 kW | 50 kW | 100 kW |
|---|---|---|---|
| Roof / area required | ~1,800 sqft canopy | ~3,500 sqft canopy | 3,500 sqft canopy + ~3,000 sqft ground |
| All-in cost (Heaven Green) | ₹15–17 lakh | ₹28–32 lakh | ₹55–60 lakh |
| Annual generation | 37,500–41,000 kWh | 75,000–82,000 kWh | 150,000–164,000 kWh |
| Annual savings (₹9/kWh) | ₹3.4–3.7 lakh | ₹6.7–7.4 lakh (self-consumed); ₹4.5–5 lakh net after export of surplus | ₹9–10 lakh net |
| AD benefit Y1 (40%, 30% tax slab) | ₹1.8–2 lakh | ₹3.4–3.8 lakh | ₹6.6–7.2 lakh |
| Payback (post-AD) | 5–6 yrs | 4.5–5 yrs | 4.5–5 yrs |
| Fits within canopy only? | Yes | Yes (tight) | No — needs ground mount |
| Best for | Small Tier-2/3 city outlets | Standard urban dealer outlets | High-throughput highway outlets, CFS adjacencies |
A 50 kW system is the sweet spot for ~80% of Indian retail outlets — the canopy holds it, the load absorbs it, the OMC approves it without ground-mount complications, and the AD benefit is large enough to compress payback below five years.

Canopy Mount vs Ground Mount Solar
Both options coexist on most ≥75 kW installations. The trade-offs.
Canopy mount (rooftop on the dispensing canopy). Existing structure, zero land cost, panels positioned 5–6 m above the forecourt for theft and dust protection, and the structural members already exist at the right pitch. Constraints — most canopies physically cap out at 40–50 kWp before the load exceeds the rated reserve, the wiring needs flameproof routing in Zone 2, and any maintenance requires forecourt access permits.
Ground mount (on adjoining dealer land). Unlimited size, easier O&M (Operations & Maintenance) access, and no Zone 2 wiring constraints because the array is beyond the 7 m hazardous boundary. Constraints — requires 8–10 sqft per installed Wp of clear land set back from the dispenser, additional fencing under PESO Rule 132, separate earth pits, and DC cable runs to the inverter location which can exceed 50 m on larger plots (driving up DC cable cost and resistance losses).
The rule we use — anything up to 50 kW goes canopy-only. From 50 to 100 kW we split (40–50 kW canopy + balance ground-mount). Above 100 kW the ground-mount portion dominates and a dedicated MMS (Module Mounting Structure) array on adjoining land is the cleaner architecture.
OMC (HP/IOC/BPCL/Reliance) Specific Solar Approval Process
Each OMC has its own dealer solar programme. The mechanics are similar but the paperwork, panel preferences, and incentive structures vary.
HP Petrol Pumps (Hindustan Petroleum)
HP runs the Petrocard Solar Scheme which offers preferred-rate financing for solar through tie-ups with SBI and Bank of Baroda, and dealer co-investment subsidies in select states. Engineering NOC goes through the Regional Retail Engineering office. HP requires Adani Solar, Waaree, or Vikram Solar panels (all ALMM-listed) and string inverters from ABB, SMA, or Sungrow. See hindustanpetroleum.com for the regional contact directory.
IOC Petrol Pumps (Indian Oil Corporation)
IOC has the largest dealer network in India (~37,000 outlets) and runs a Dealer Solar Programme with engineering clearance through the State Office’s RE&P cell. IOC’s panel approval list is broader (10+ manufacturers) but the structural compliance check on canopies is the strictest among OMCs. IOC also offers a brand-promotion co-funding scheme where the OMC contributes 10–15% of CAPEX in exchange for IOC-branded signage on the solar array. Refer to the dealer portal at iocl.com for the current scheme.
BPCL Petrol Pumps (Bharat Petroleum)
BPCL’s Pure for Sure programme has a parallel Pure for Sure Green initiative that nudges dealers toward solarisation with a fast-tracked NOC (typically 12–18 days vs 25 days standard). BPCL approves panels via the central tender process and the approved-vendor list rotates annually. The BPCL retail dealer site at bharatpetroleum.in carries the current empanelment.
Reliance / Jio-bp Petrol Pumps
Reliance retail outlets (now branded Jio-bp under the joint venture with BP) operate under a tighter, more centralised approval model. The Jio-bp Solar Standard mandates string inverters with module-level monitoring, dual-axis surge protection, and a remote monitoring tie-in to the chain HQ. Approval timelines are 20–35 days but the engineering specifications are the most prescriptive — and the highest quality bar — of any OMC.
Cost, AD, ROI for Petrol Pump Solar
The financial case rests on three numbers — CAPEX, the AD tax shield, and the displaced tariff. Walk through a 50 kW example.
| Line item | 50 kW Petrol Pump Solar |
|---|---|
| All-in CAPEX (panels, inverter, MMS, BoS, install, PESO docs) | ₹30,00,000 |
| Year 1 AD claim (40% of CAPEX) | ₹12,00,000 |
| Tax saved Y1 (assuming 30% effective rate on dealer firm/LLP) | ₹3,60,000 |
| Effective Y1 CAPEX | ₹26,40,000 |
| Annual generation | 78,000 kWh |
| Self-consumption % | 80% (= 62,400 kWh) |
| Export to grid | 15,600 kWh @ ₹3.5/kWh = ₹54,600 |
| Self-consumption savings @ ₹9/kWh | ₹5,61,600 |
| Total Y1 revenue impact | ₹6,16,200 |
| Effective payback period | 4.3–4.8 years |
Read the Accelerated Depreciation solar tax guide for the line-item Income Tax Act sections (Section 32 read with Rule 5, Appendix I) and the conditions under which a dealer firm can claim 40% in Year 1. If the dealer entity is a proprietorship in a lower tax bracket the AD shield is smaller; if it’s a Pvt Ltd or LLP at 25–30% effective tax, the AD math works as shown.
OMC Commercial Tariff Reference (2026 Indicative)
| State / DISCOM | Commercial slab tariff | Solar self-consumption value |
|---|---|---|
| Rajasthan (JVVNL/JdVVNL/AVVNL) | ₹8.5–₹10.2/kWh | ₹9.4/kWh blended |
| Gujarat (UGVCL/MGVCL/DGVCL) | ₹7.8–₹9.4/kWh | ₹8.6/kWh blended |
| Maharashtra (MSEDCL) | ₹10.5–₹12.5/kWh | ₹11.2/kWh blended |
| Delhi (BSES/TPDDL) | ₹9.4–₹11.8/kWh | ₹10.5/kWh blended |
| Karnataka (BESCOM/HESCOM) | ₹8.2–₹9.8/kWh | ₹9.0/kWh blended |
| Tamil Nadu (TANGEDCO) | ₹8.8–₹10.4/kWh | ₹9.5/kWh blended |
Tariffs include fixed charges, fuel surcharge and electricity duty equivalents normalised to ₹/kWh; refer to the MNRE rooftop solar dashboard for the latest commercial slab structure in your state.
Common Petrol Pump Solar Installation Mistakes
Across the 100+ HP, IOC, and BPCL outlets we’ve audited or installed, six mistakes recur. Each one is preventable with a 30-minute design review.
-
1
Inverter mounted within Zone 2. Contractors often wall-mount the inverter on the dispenser-side column for short cable runs. PESO rejects this at witness — the inverter must sit beyond the 7 m hazardous boundary, typically on the shop wall or in a dedicated electrical room.
-
2
Exposed DC cabling across the dispenser island. All DC string wiring within 7 m of any dispenser must be in metallic conduit with flameproof glands. Open-tray or PVC-trunked DC runs fail PESO inspection and trigger licence-suspension proceedings.
-
3
Skipping the OMC engineering NOC. Installing without HP/IOC/BPCL/Reliance written engineering clearance is a dealership-agreement breach. The OMC can demand removal at the dealer's cost and invoke penalty clauses on the dealership.
-
4
Shared earth pit with canopy lighting. Solar DC and AC earthing must be on a dedicated pit per IS 3043, not bonded to the existing canopy lighting earth. A shared earth path during a lightning strike can backfeed transient voltages into the dispenser controllers.
-
5
Overloading the canopy structure. Older MS canopies (pre-2015) often have lower live-load ratings than newer ones. A structural certificate from a licensed structural engineer is mandatory before mounting; assuming the canopy will hold 50 kW without calculation is how panels end up in the forecourt after the first monsoon.
-
6
No interface with the existing fire suppression. The pump's existing fire alarm panel must trigger a hard DC isolation of the solar array. Contractors who skip this interlock fail PESO commissioning every time.
For the deeper safety architecture — fire compartmentation, smoke detection logic, and emergency DC shutoff — see the solar fire safety protocols guide.
CAPEX vs OPEX for Petrol Pump Solar
The dealer can fund the system through CAPEX (Capital Expenditure — outright purchase) or OPEX (Operational Expenditure — third-party-owned PPA / RESCO model). Petrol pumps are an unusual category because the operator is a creditworthy single-counterparty with predictable 24/7 load and a long dealership tenure — which makes them attractive to OPEX providers.
- + Full AD benefit captured in Y1 — ₹3.4–3.8 lakh tax shield on 50 kW
- + Asset on dealer balance sheet — strengthens loan position
- + 25-year savings retained by dealer; no third-party tariff escalation
- + Full control over O&M vendor and system upgrades
- + Post-payback the electricity is effectively free for 18–20 years
- − ₹28–32 lakh upfront commitment for 50 kW
- − Dealer carries performance and degradation risk
- − AMC (Annual Maintenance Contract) overhead at ₹15,000–25,000/yr
- − Project execution risk falls on the dealer
- − Capital locked up that could fund a tank upgrade or second outlet
- + Zero upfront cost — RESCO funds CAPEX
- + PPA (Power Purchase Agreement) tariff ₹5.5–6.5/kWh vs grid ₹9–11/kWh
- + O&M risk transferred to PPA developer
- + Day-1 savings of ₹2–2.5 lakh/yr on 50 kW
- + Buyout option typically after Year 5–7 at residual value
- − 15–25 year PPA lock-in; cannot exit without buyout
- − Dealer loses AD benefit — developer captures it
- − Annual PPA tariff escalation of 2–4% baked into contract
- − Lifetime savings smaller than CAPEX (₹1.5 cr vs ₹2.3 cr over 25 yrs)
- − Developer credit risk if RESCO fails before Year 5
Verdict. For a dealer in the 25–30% tax bracket who can fund ₹28–32 lakh, CAPEX wins decisively — the AD shield, lifetime savings, and post-payback free electricity create a 25-year IRR of 22–26%. For a dealer who is cash-tight, has multiple outlets, or wants to keep capital free for expansion, OPEX is the right call — accept the lifetime savings haircut in exchange for zero upfront cost and instant Day-1 ₹/kWh savings. The full numerical comparison sits in our OPEX vs CAPEX 2026 guide.

Frequently Asked Questions
Can I install solar on my HP, IOC, or BPCL petrol pump without OMC approval?
No. The dealership agreement with HP, IOC, BPCL, or Reliance prohibits any modification to the licensed premises — including the canopy and electrical system — without written engineering NOC from the OMC’s Retail Engineering & Projects (RE&P) cell. Installing without this clearance is a dealership-agreement breach that the OMC can act on by demanding removal at the dealer’s cost or invoking penalty clauses. NOC takes 15–30 days; submit early and run PESO clearance in parallel.
What is the PESO clearance for petrol pump solar and how long does it take?
PESO (Petroleum and Explosives Safety Organisation) clearance is the regulatory sign-off under the Petroleum Rules 2002 that confirms the solar installation complies with hazardous zone classification — Zone 0, Zone 1, Zone 2, and non-hazardous areas. The application goes to the regional Joint Chief Controller of Explosives with the OMC-approved layout, zone classification drawing, and intrinsically safe equipment specifications. Clean submissions clear in 30–45 days; first-time submissions with incomplete fire-interlock documentation often go through a query cycle that adds 15–25 days.
Where exactly can I place solar panels relative to the dispenser nozzle?
Under PESO hazardous zone rules, solar panels cannot sit in Zone 0 (inside the fuel tank — not a concern) or Zone 1 (within 3 metres of any dispenser nozzle or 1.5 metres of a vent pipe outlet). Panels can sit in Zone 2 (3–7 m from the dispenser) only if the wiring is in metallic conduit, junction boxes are flameproof Ex d rated, and AC/DC isolators are Ex e rated. Beyond 7 m from any dispenser the area is non-hazardous and standard solar PV is allowed without special enclosures. The canopy roof above a dispenser typically sits in Zone 2 because the panel surface is 4.5–5.5 m above ground.
How much does a 50 kW petrol pump solar system cost in 2026?
A 50 kW canopy-mounted solar system for an Indian petrol pump costs ₹28–32 lakh all-in — including modules, string inverter, MMS (Module Mounting Structure), balance of system, intrinsically safe wiring for Zone 2, OMC engineering NOC fees, PESO clearance fees, structural certification, and commissioning. Annual generation is 75,000–82,000 kWh and annual savings at ₹9/kWh blended commercial tariff are ₹4.5–5 lakh net of grid export. With Accelerated Depreciation claimed at 40% in Year 1, the post-tax payback period lands at 4.5–5 years.
Does the OMC pay any subsidy or co-fund solar at HP, IOC, or BPCL pumps?
The central government does not run a direct subsidy for commercial solar at petrol pumps — PM Suryaghar is residential only and the MNRE CFA (Central Financial Assistance) for commercial is closed. However, individual OMCs run dealer co-funding schemes. IOC offers a brand-promotion contribution of 10–15% of CAPEX in exchange for IOC-branded signage on the array. HP’s Petrocard Solar Scheme offers preferred-rate solar loans through SBI and Bank of Baroda. BPCL’s Pure for Sure Green has a fast-track NOC. Reliance Jio-bp has a centralised tendered programme. Check with your regional OMC office for the current incentive structure.
Can I claim Accelerated Depreciation on petrol pump solar if I’m a sole proprietorship?
Yes — Accelerated Depreciation under Section 32 of the Income Tax Act read with Rule 5 and Appendix I allows a 40% Year 1 depreciation on solar PV plant for any business entity, including sole proprietorships. The constraint is taxable income — a proprietorship needs sufficient business income against which to set the AD claim. If your taxable income is below the AD claim amount, the unutilised portion carries forward as an unabsorbed depreciation balance for subsequent years. LLPs and Pvt Ltd companies typically capture the AD benefit faster because of larger taxable income bases.
What size solar fits on a standard Indian petrol pump canopy?
A standard MS canopy at an Indian retail outlet is 18–24 m long, 12–15 m deep — roughly 3,500–5,000 sqft of mountable surface after deducting Zone 1 exclusion areas above each dispenser and clearance for signage. This supports 30–50 kWp of crystalline silicon panels at typical 10 sqft/kWp packing density. Larger 75–100 kW systems require splitting the array between the canopy (40–50 kW) and a ground-mount array on adjoining dealer land — typically 3,000–4,000 sqft set back at least 7 m from any dispenser.
How long does the full petrol pump solar installation process take?
From decision to commissioned plant, allow 75–95 days for a clean project. OMC engineering NOC takes 15–30 days, PESO clearance 30–45 days (run in parallel with OMC), DISCOM net metering approval 25–35 days, installation 8–12 working days, and the final OMC audit plus PESO witness commissioning another 10–15 days. Sites with prior OMC solar deployments in the dealer network and pre-existing PESO familiarity (Maharashtra, Gujarat) move faster — 60–75 days is achievable. First-time OMC-region installations or sites without a structural certificate on file run 100–120 days.
