COMMERCIAL & INDUSTRIAL

MW-scale solar, structured your way

Factories, warehouses, institutions — own the plant (CAPEX) or pay nothing upfront (OPEX/PPA). We engineer both, and tell you honestly which fits.

Four ways to buy solar

Same sun, different balance sheets.

CAPEX (ownership)
You invest, you own, you keep every rupee of savings — plus 40% accelerated depreciation. Best lifetime economics; payback typically 3–4 years on Gujarat C&I tariffs.
OPEX / PPA (zero investment)
A developer finances and owns the plant on your roof or land; you sign a power purchase agreement at a per-unit rate well below the grid. Zero capex, savings from day one.
Open access
Buy solar power from an off-site plant over the grid — for consumers above 100 kW sanctioned load. Ideal when your roof is too small for your consumption.
Group captive
Co-own (26%+ equity) an off-site plant with other consumers and escape cross-subsidy surcharges — the most tax-and-charge-efficient structure for large loads.

Best forConserving capital, quick board approval

Indicative first-cut using ~₹40k/kWp C&I install cost, ~1550 kWh/kWp/yr generation and a ~₹3.90/unit PPA. Actual numbers depend on site, DISCOM, open-access charges and contract structure — request a bankable feasibility study.

Proven on industrial rooftops

5 MW+ of our installed base is industrial — Surat textile mills and manufacturing units like Ravi Textile (600 kW), Ravi Sizer (280 kW) and Shree Ganesh Fabrics (260 kW), running daytime-heavy loads where solar self-consumption does the most work.

C&I FAQ

CAPEX or OPEX — which should we choose?

CAPEX maximises lifetime savings and tax benefits (40% accelerated depreciation) if you have capital and tax appetite. OPEX/PPA needs zero investment and delivers immediate per-unit savings — better when capital is reserved for core business. Many clients start OPEX and buy out the asset later.

What size do we need?

A useful first cut: annual consumption (kWh) ÷ ~1,550 kWh per kWp. A 50,000-unit/month factory needs roughly 400 kWp. Roof area, sanctioned load and DISCOM rules set the practical ceiling — our feasibility study nails the exact number.

Do daytime-heavy loads matter?

Yes — solar generates when factories consume. Textile, manufacturing and cold-storage loads typically self-consume 90%+ of generation, which is where solar saves the full grid rate.

What about net metering for C&I?

Gujarat allows net metering/net billing for C&I within DISCOM limits; surplus settlement rates are lower than the retail rate, so we size plants to your daytime load first. We handle the entire DISCOM application.
