Solar for MSMEs in India: Subsidy, Eligibility & ROI (2026)

Quick answer: For most manufacturing and processing MSMEs, electricity is the 2nd or 3rd largest operating cost — in Telangana, commercial & industrial (C&I) power runs ₹7–9 per unit and climbs 3–5% a year. Rooftop solar generates power at roughly half that cost, pays back in 3–5 years, and comes with a 40% accelerated depreciation benefit in year one if you own the asset. You can also start with zero upfront cost under an OPEX/PPA model, where a developer funds and owns the system and you simply pay a fixed, lower rate per unit. Real numbers from two Greentek MSME installations in Telangana are below.

Why energy costs are a bigger problem than most MSMEs realise

Factor	What it means for you
₹7 – 9 per unit	Typical C&I tariff in Telangana — among the higher slabs in India
3 – 5% a year	Typical annual rise in commercial power tariffs — and it only moves one way
15 – 40%	Share of total operating cost that energy takes in energy-intensive MSMEs
Green requirements	Large buyers and exporters increasingly ask for a clean-energy supply chain

The takeaway: you can't control the tariff, but you can control how many units you buy from the grid. That's the entire logic of solar for a business — not a sustainability gesture, a direct line item on the P&L.

Two steps, in the right order: conserve, then generate

The cheapest, greenest unit of energy is the one you never have to buy. Most MSMEs can trim 10–20% off their energy bill with efficiency measures that pay back in months, before spending anything on solar:

Energy audit — find where every unit goes; the foundation for all savings
LED lighting — 50–70% lower lighting load, near-instant payback
Efficient motors & VFDs — IE3/IE4 motors and drives cut the biggest factory load
Power-factor correction — avoid penalties and recover capacity on your connection
Compressed air & HVAC fixes — leaks and right-sizing are often the silent energy drain
Smart monitoring — meter and track loads so savings actually stick

Only after that does rooftop solar take over — meeting the remaining demand with your own MNRE-grade plant, with net metering banking any daytime surplus for use later. The asset then runs for 25+ years.

CAPEX or OPEX/PPA — which model fits your business?

	CAPEX (you own)	OPEX / PPA (Greentek owns)
Upfront cost	You fund the system	Zero — Greentek funds it
You pay for	One-time capital cost	Only the units generated
Tariff	Near-zero after payback	Fixed ₹/unit, below grid rate
Best for	A strong balance sheet	Conserving cash flow
Tax benefit	40% accelerated depreciation	Built into developer pricing
Savings	Highest over 25 years	Immediate, from day one

Greentek delivers both models and helps you pick the one that fits your balance sheet and cash flow — there's no single right answer, only the right fit for your business. See our full comparison in CAPEX vs OPEX for solar.

The economics: why the numbers work

Your own rooftop power typically costs roughly half of what you buy from the grid — illustratively, about ₹4/unit for solar against ₹8/unit for grid C&I power — and the gap only widens as tariffs keep rising.

Metric	Typical range
Payback (CAPEX)	3 – 5 years
Accelerated depreciation (CAPEX, year one)	40%
Low-cost generation after payback	25+ years

Incentives and support built into the switch

Accelerated depreciation — claim 40% depreciation on the solar asset in year one, a meaningful tax shield for profit-making MSMEs choosing the CAPEX route.
Net & gross metering — export surplus to the DISCOM and earn credits under the Telangana net-metering framework.
Easy financing — collateral-light solar loans, and the RESCO/OPEX route, mean you can start with little or no capital.
MSME & RAMP push — schemes like RAMP, backed by CII and TSIIC, support MSME competitiveness, greening and capability building; Greentek offers participating MSMEs a free, no-obligation energy and solar assessment through this route.

Two Greentek MSME case studies, Telangana

Chemo India — 300kW rooftop, zero upfront cost (OPEX/PPA)

A Telangana pharmaceutical manufacturer wanted to cut a heavy daytime power bill without locking up capital in a solar plant. Greentek designed and built a 300kW rooftop plant end-to-end under an OPEX/PPA model — Greentek funded the system, the client pays only for units generated at a fixed rate below grid, with net metering and 25-year O&M and monitoring included.

Units generated	~4.5 lakh/year
Saved every year, from day one	₹13.5 lakh+
Upfront investment by the client	₹0
CO₂ avoided per year	~320 tonnes

Federal Plastek — 310kW, owned outright (CAPEX)

A plastics-manufacturing MSME with heavy daytime load and a healthy balance sheet wanted to own its generation and capture the full tax and savings upside. Greentek delivered a 310kW rooftop plant as a full turnkey EPC project under the CAPEX model — the company owns the asset and claimed 40% accelerated depreciation in year one, with 25-year O&M, monitoring and warranty cover.

Units generated	~4.7 lakh/year
Saved every year at grid rates	₹37 lakh+
Payback, after depreciation	~3 years
Saved over the 25-year life	₹8 crore+

Is your business eligible?

Broadly, if you have a commercial or industrial electricity connection, a shadow-free rooftop or open area, and daytime power consumption, you're a candidate — from a small workshop to a multi-acre factory. Eligibility and the exact incentive mix (depreciation, net-metering terms, any state-level support) depend on your DISCOM, connection type and consumption pattern, which is exactly what a free assessment establishes.

How an MSME gets started — at no cost

Free energy assessment — Greentek reviews your bills and rooftop, and models savings under both CAPEX and OPEX.
A clear business case — you receive sizing, payback, and tax and financing options as a decision-ready proposal.
Start small, scale up — begin with conservation measures and a pilot rooftop block, then expand as savings prove out.

Frequently asked questions

How much does solar cost for an MSME?

It depends entirely on load and roof size — from a modest 50–100kW workshop system to several hundred kW for a full factory rooftop. A free site survey and bill study gives an exact, sized quote; the two case studies above show real installed sizes and results (300kW and 310kW).

Is there a subsidy for MSME rooftop solar?

MSME/commercial solar doesn't use the residential PM Surya Ghar subsidy. Instead, the main financial benefits are 40% accelerated depreciation in year one (CAPEX route), collateral-light financing, and schemes like RAMP (backed by CII and TSIIC) offering free assessments to participating MSMEs.

What's the difference between CAPEX and OPEX/PPA for a business?

Under CAPEX, you fund and own the system and get the accelerated depreciation tax benefit — highest savings over 25 years, but needs capital upfront. Under OPEX/PPA, a developer like Greentek funds and owns the system; you pay only for units generated at a fixed rate below grid, with zero upfront cost. See our full CAPEX vs OPEX comparison.

How fast does it pay back?

Typically 3–5 years for a CAPEX system, faster with the 40% year-one depreciation factored in — Federal Plastek's 310kW installation paid back in about 3 years. OPEX/PPA has no payback period for the client since there's no upfront investment; savings start from day one.

Does solar work for a small workshop, or only large factories?

Both. Greentek's own portfolio spans roughly 250kW to multi-MW industrial rooftops, plus utility-scale work. What matters is roof area, daytime consumption and connection type — not headcount.
