Built for performance. Aligned to policy.

Cut daytime grid draw, stabilise costs and strengthen your ESG story—without disrupting operations. Large rooftop solar array on an industrial shed with walkways.

How rooftop solar works for businesses

Power flow in a nutshell

Sunlight → PV modules → DC

Inverter converts DC → AC to feed your LT/HT panel

Bi-directional/smart meter logs import & export

Settlement as per policy: net metering, net billing or gross

Why it benefits owners & operators

  • Reduce OPEX: Offset costly daytime units
  • Predictability: Hedge against tariff hikes
  • ESG / ratings: Lower Scope-2 emissions
  • Scalable: Rooftop, carport, ground-mount
  • Low disruption: Fast execution & safe methods

Frequently asked questions

Many C&I sites see a 20–60% reduction in total energy cost. It depends on tariff, load timing, roof area and the chosen policy route.

Frequently 3–6 years. We share a site-specific financial model with yield, savings and cash flow.

Work is planned around shifts and safety zones. We use approved methods for RCC and metal roofs to protect warranties and avoid downtime.

Yes. Drawings, applications, inspections and meter commissioning (net, gross or billing) are coordinated with your DISCOM and as per CEA norms.

AMC with cleaning, PR checks, thermography and earthing audits. Remote alarms ensure quick response for uptime.
