Capex vs RESCO

Buy the plant outright — or pay zero upfront and lock a lower tariff.

CAPEX (you own the plant)

40% accelerated depreciation in year 1
60–80% lifetime electricity savings
Payback in 4–5 years; 20+ yrs of free power
Full asset value on your books
Eligible for accelerated depreciation tax shield

RESCO

RESCO / PPA (zero upfront)

Zero capex — we own, install & maintain
You pay only for units consumed
Tariff locked 20–30% below DISCOM rate
Buy-out option after 5 years
Off-balance-sheet for the lifetime of the PPA

How it works

From load audit to commissioning — 60–120 days, end to end.

01

Site & load audit Day 1–10

Structural assessment, 12-month load profile review, shading analysis, transformer capacity check — and your fixed-price proposal.
02

Design, PO & financing Day 10–25

Detailed engineering drawings, single-line diagram, and PO. If financing, we coordinate NBFC / bank approval in parallel.
03

DISCOM & CEIG approvals Day 25–60

Net / gross / open-access metering application, transmission tie-in, and electrical inspector clearance — we drive every form.
04

Installation Day 45–100

Civil works, mounting, panel install, inverter & SCADA commissioning. 1 MW plants typically complete in 30–45 working days with zero disruption to operations.
05

Commissioning & performance lock Day 100–120

DISCOM meter swap, performance ratio verification, SCADA handover, and start of multi-year AMC with guaranteed generation SLA.

Why Vermson

A solar EPC that thinks like your CFO, not just your electrician.

Financial model with the proposal

Every commercial quote ships with NPV, IRR, payback and depreciation tax shield modelled on your real bills — not generic ROI claims.

Performance SLA, not just install

We guarantee a minimum generation ratio over 25 years. If the plant under-produces, we make it good. Real skin in the game.

Operations-grade SCADA

Live performance dashboard, automated alerts, scheduled maintenance windows — built for facility managers, not toy mobile apps.

FAQ

What CFOs and facility heads ask us first

Answers to the questions we hear most. Have a different one? Drop us a message and we'll write you back.

01.What's the real payback for a 500 kW commercial plant?

With 40% accelerated depreciation, GST input credit and typical commercial tariffs of ₹8–10/unit, a 500 kW plant pays back in 4–5 years. Over its 25-year life it delivers 4–5× return on capex. Every quote we send includes a CFO-friendly financial model with NPV and IRR — not just "savings per month".

CAPEX wins if you have available capital and want maximum lifetime ROI + depreciation tax shield. RESCO/PPA wins if you'd rather deploy capital elsewhere and just want a lower, locked-in tariff with zero upfront and zero operational responsibility. We offer both and model both in your proposal.

Net metering: you offset your bill with what you generate. Gross metering: you sell everything to the DISCOM at a fixed feed-in tariff. Open access: for 1 MW+ consumers, you generate at a different location and wheel power to your facility via the grid — best for industrial loads where rooftop isn't enough.

Zero shutdown required. We schedule civil works during off-hours, route cabling outside production areas, and the only downtime is the 4-hour DISCOM meter swap — which we coordinate around your peak operations. Hospitals stay running. Factories don't stop.

Our commercial contracts ship with a 25-year Performance Ratio SLA. If actual generation falls below the agreed PR (accounting for irradiance), we either compensate the shortfall or remediate at our cost. The SLA is enforceable — we have real skin in the game, not just a panel warranty pass-through.

Yes — we ship CO₂-equivalent abatement data, ESG-aligned impact metrics and BRSR-compatible disclosures every quarter. A 500 kW plant offsets ~600 tonnes of CO₂ a year and feeds straight into Scope 2 reduction reporting.
