Why storage pays for itself

Solar covers the day. Storage covers the rest.

Sunbuilt PowerVault pairs with your solar plant to displace the most expensive units on your bill — peak demand charges, time-of-day surcharges and diesel generator runtime — not the cheapest ones.

If our work passes PSU tender inspectors, it will pass yours.

PSU tenders demand bank guarantees, third-party inspection, ALMM-compliant materials and multi-year performance commitments. We bring that same rigour to every factory rooftop in NCR — so your solar asset performs for 25 years, not just on day one.

FAQ

Common questions from NCR businesses

How much can a factory in Gurugram or NCR save with rooftop solar?

Most C&I consumers offset a large share of their daytime consumption at a levelised solar cost well below DISCOM commercial tariffs, with typical payback of 2.5–3.5 years and a system life of 25 years. Share your monthly bill and roof area and we'll send an exact savings estimate as part of a techno-commercial feasibility assessment.

Do you handle net-metering and DISCOM approvals?

Yes — end to end. We are empanelled with DHBVN and UHBVN in Haryana and registered with TPDDL and BSES in Delhi, so applications, inspections and net-metering agreements are processed by us directly.

Is there a government subsidy for solar?

Residential customers can claim central subsidy under PM Surya Ghar: Muft Bijli Yojana, where we are a registered vendor and file the paperwork for you. C&I customers benefit from accelerated depreciation and open-access/net-metering policies instead.

What is Sunbuilt PowerVault?

Sunbuilt PowerVault is our industrial battery energy storage (BESS) product line, scaling from a 125 kW all-in-one cabinet to a 2.5 MW modular plant, with IRASUS-powered energy intelligence built in. See the full PowerVault product range.

Do you provide maintenance after installation?

Yes — O&M and AMC contracts including cleaning, monitoring, inverter service and generation reports. We hold O&M contracts for government solar plants, including a 100 kW plant for NIELIT and GAIL's corporate office system in Delhi.

Do you operate outside Delhi NCR?

Our PSU and institutional project delivery spans 19+ states. For residential and C&I solar closer to Jaipur, we also work through our channel partner based in Bassi, Jaipur, Rajasthan — see Locations.

Can you supply solar street lights for our campus or industrial perimeter?

Yes — standalone solar street lights and high-mast systems, supply-only or turnkey. We have delivered street-lighting projects for ITBP, CAPF, BEL/Indian Air Force, IREL and GAIL sites across India.
