How long does a 2 MW solar plant take to build?

Typical end-to-end: 60–90 days from signed PO. That includes detailed design, structural audit, equipment procurement, civil works, installation, commissioning, and DISCOM net-metering approval. We file the DISCOM application in parallel with civil works, not after — that's the biggest schedule-saver at this size.

What roof area do I actually need for 2 MW?

Around 2,00,000 sqft of shadow-free roof at standard mounting. If the roof is short, we extend with elevated structures over parking or driveways — adds shade for vehicles, doubles up the asset, and at 2 MW the incremental steel cost is usually 4–7% of project cost.

Behind-the-meter vs open access vs group captive — which structure fits at 2 MW?

Three real options at MW scale: (1) behind-the-meter rooftop consumed on-site — simplest, no wheeling charges, needs matching daytime load; (2) open access wheeling from an off-site plant — pays cross-subsidy surcharge and wheeling charges, viable when rooftop is short; (3) group captive with 26% consumer equity in a special-purpose vehicle — exempts from cross-subsidy surcharge, best for consumers with >1 MW connected load. Choice hinges on your daytime consumption profile, not plant size.

How does the group captive 26% equity math work at 2 MW?

Regulation says the consumer must hold at least 26% equity in the SPV that owns the plant and consume at least 51% of its annual generation to qualify as captive. Typical structure: developer holds 74%, consumer holds 26%. The exemption saves cross-subsidy surcharge (Rs. 1–3/unit in most states) plus additional surcharge. Pays back the equity in 2–4 years for a well-matched load. We structure the SPV with your CA and file the CEA captive declaration.

How much do wheeling and cross-subsidy charges eat into the tariff on open access at 2 MW?

Depends on state — this is where the math turns. UP: cross-subsidy surcharge Rs. 1.20–1.80/unit + wheeling Rs. 0.35/unit + banking losses ~2%. Haryana: cross-subsidy Rs. 1.50–2.10/unit + wheeling Rs. 0.42/unit. Delhi does not allow rooftop wheeling. Total open-access delivered cost typically lands Rs. 5.50–6.50/unit versus behind-the-meter LCOE of Rs. 3.20–3.80/unit — behind-the-meter wins wherever the load can absorb it.

At 2 MW, is on-site rooftop still cheaper than an off-site open-access solar plant?

Behind-the-meter rooftop LCOE at 2 MW is roughly Rs. 3.20–3.80/unit. Off-site open access delivered to your meter typically lands Rs. 5.20–6.50/unit after wheeling, cross-subsidy surcharge and banking losses. Behind-the-meter wins by Rs. 1.50–3.00/unit — a 2 MW plant generating 30 lakh units/year translates to Rs. 45L–90L/year saving. Open access is a fallback when roof is short or shaded, not a first choice.

What's the O&M SLA structure at 2 MW — performance ratio guarantee, response times, penalty clauses?

Standard structure: 25-year O&M with performance-ratio guarantee of ≥80% for years 1–10 and ≥75% for years 11–25. Response SLA: critical fault (inverter down, generation halted) 4 hours on-site in Delhi NCR, 8 hours pan-India. Cleaning cycle: 2–4 rounds/month depending on air quality. Penalty clause: shortfall against PR guarantee compensated at Rs. 4/unit lost. Full SCADA + string-level monitoring 24×7. This is what makes O&M an enforceable contract, not a courtesy.

CAPEX vs OPEX/PPA — Which Fits You?

The honest answer: it depends on your tax position and your appetite for capex. We do both. Here's the side-by-side.

At MW scale the decision expands to group captive and open access.

Beyond Rs. 4Cr project size, three additional structures enter the tradeoff: group captive with 26% consumer equity (exempts cross-subsidy surcharge), open access from an off-site plant (pays wheeling + CSS), and third-party OPEX with a longer PPA. Banks want a Chartered Engineer-certified DPR with 25-year IRR/NPV/DSCR modelling — we ship that as part of the sales cycle rather than as a separate advisory.

What Actually Breaks at 2 MW

At 2 MW the site strategy — rooftop vs land vs elevated — decides the project economics more than panel choice.

Open access viability against behind-the-meter

Behind-the-meter LCOE at 2 MW is Rs. 3.20–3.80/unit. Off-site open access lands Rs. 5.20–6.50/unit after wheeling, cross-subsidy and banking losses — a Rs. 1.50–3.00/unit gap. On 30 lakh units/year that's Rs. 45L–90L saved by keeping generation on-site wherever the load can absorb it.

Land-lease vs rooftop capex tradeoff

Rooftop at 2 MW usually needs 2 lakh sqft — few single-shed sites clear that. Options: distribute across multiple sheds (adds cabling cost, saves civil), elevated parking-shed extension (Rs. 8–12L/100 kW premium), or off-site land lease (opens open-access complexity). We model all three before recommending.

O&M SLA is an enforceable contract

Standard: 25-yr O&M with performance-ratio guarantee ≥80% for years 1–10, ≥75% for years 11–25. Critical-fault response 4 hours in Delhi NCR, 8 hours pan-India. Shortfall against PR guarantee compensated at Rs. 4/unit lost. This is the clause that turns O&M from courtesy to contract.

Financing a 2 MW Plant

Most C&I customers don't pay full capex up front. Three routes — bank term loan, NBFC, or OPEX/PPA. We help with the DPR for all three; we don't push a particular lender.
