Solar That Pays Back Before It Pays Off
Large plants close solar through tenders and consultants. Small and medium industries are left to figure it out alone — usually from a salesperson. This is the neutral version: the real economics of factory rooftop solar, the tax benefits, and the numbers before anyone quotes you.
Why MSMEs Are Going Solar First
Power Is a Top-3 Cost
For most small factories, cold storages, and workshops, electricity trails only raw material and labour. Solar attacks it directly, at ₹2.5–4 per unit against commercial tariffs of ₹8–11.
40% Accelerated Depreciation
Profit-making businesses write down 40% of the solar asset in year one, creating a tax shield that pulls payback below three years — a benefit homes and societies cannot claim.
A Fixed Cost, Made Predictable
A 25-year asset locks in your largest controllable cost against tariff hikes that compound every year. That predictability is worth as much as the saving itself.
Non-DCR window for net metering & open access: 31 December 2026
ALMM List-II (domestic solar cells) became mandatory for most projects from 1 June 2026 — government/PSU tenders have no exemption. Net-metering and open-access renewable projects specifically got relief: those commissioned on or before 31 December 2026 can still use non-DCR (imported-cell) panels; from 1 January 2027 they too must use ALMM List-II compliant panels. What counts is your commissioning date (DISCOM inspection + grid sync), not your order date.

The Levers Homes Don’t Have
Commercial and industrial consumers don’t get PM Surya Ghar subsidy — but the business-only routes below often beat it.

What is AD?Open Access
No roof space? Green open access (from 100 kW) lets you buy solar from an off-site farm through the grid — often below your DISCOM tariff.
How it worksCaptive & CAPEX vs RESCO
Own it for maximum lifetime saving, or take a zero-investment RESCO/PPA. The calculator models both over 25 years.

Unlike big plants, MSMEs rarely have a procurement team or a vendor panel — which is exactly where wrong choices get made. Tell us your location, monthly bill, and roof or land available, and we’ll point you toward the right next step. Neutral guidance, no commission-driven pitch.
