Renewable energy developer & EPC contractor

We develop, engineer and operate renewable power projects across India.

Commercial rooftop, government rooftop and open access power — designed, built, financed and maintained by our own teams. A single point of accountability from feasibility study to the twenty-fifth year of generation.

Where we focus

Three segments we build for, each with its own procurement route, engineering constraints and delivery obligations.

Commercial & industrial

Commercial rooftop

Rooftop generation engineered around your load profile and your operations. We handle structural assessment, single-line design, DISCOM approvals and net metering, then run the asset under a long-term O&M contract. Installations are phased around shifts and production schedules so output goes up without downtime.

Commercial solar

Public sector

Government rooftop

Rooftop solar for government buildings, institutions and public undertakings, executed to tender specification. We work within GeM and departmental procurement, meet the documentation and quality regimes those contracts require, and take responsibility for commissioning, handover and the full defect liability period.

Government rooftop

Municipal & highways

Solar street lighting

Standalone and centrally monitored solar street lighting for municipal bodies, panchayats and highway authorities. We survey the alignment, size the systems for local irradiance and autonomy requirements, install across dispersed sites, and maintain them — including battery replacement cycles — through the contract term.

Solar street lighting

One contract, six stages, no handoffs

Every stage below is delivered by Zero Carbon teams. You are not managing a chain of vendors, and there is no point in the project where responsibility transfers to someone else.

Feasibility

Site survey, shadow analysis, load profiling and structural assessment. You get a yield estimate you can underwrite, not a sales figure.

Design & engineering

In-house electrical and structural design: single-line diagrams, layout, mounting, cable sizing, protection and yield simulation.

Approvals & liaison

DISCOM applications, net metering, open access clearances, subsidy and tender documentation. We run the paperwork.

Procurement

Tier-one modules, inverters and balance of system specified by engineering, not by margin. Full traceability of what goes on your roof.

Construction & commissioning

Our own execution teams, phased around your operations, with testing and documented handover.

Operations & maintenance

Remote monitoring, in-house O&M crews and a 48-hour service guarantee for the life of the asset.

Our end-to-end EPC solutions focus on offering design, engineering, and O&M for solar projects across the commercial, industrial, government and institutional sectors

Three ways to own the power

The right model depends on whether your constraint is capital budget, roof space or tariff. We deliver under all three.

CAPEX

You own the asset

We design, build and commission the plant, then maintain it under contract. Best where you want the depreciation benefit and the full generation upside over the asset's life.

How ownership works

OPEX / RESCO

We fund and operate it

We own the plant on your site and carry the capital. You pay only for the units you consume, at a tariff below your grid rate, with no investment and no operational responsibility.

How zero-investment works

Open Access

No plant on your premises

Renewable power is wheeled to your facility from our projects under a long-term PPA. Suits sites without usable roof area, or loads larger than a rooftop can serve.

“I wanted a trustworthy solar provider, and Zero Carbon exceeded expectations. They handled government approvals and gave me a reliable system that works like a charm

Neha Bansal

Architect

From the initial consultation to after-sales support, Zero Carbon impressed me at every step. The installation was quick, and their system is running flawlessly.

Ajay Thakur

Retired Officer

I was always concerned about my carbon footprint. Thanks to Zero Carbon , my home now runs on clean, reliable solar energy. Their team explained everything and delivered exactly as promised.

Suman Roy

Teacher

Zero Carbon transformed my rooftop into a power source. Within months, I saw a 70% drop in electricity bills. The process was smooth, and the team was professional throughout.

Frequently Asked Questions

To use open access power, your business must have a minimum contracted demand as per your state’s regulations (usually 1 MW or more). You also need to sign a power purchase agreement (PPA) with the wind energy generator.

No. Open Access Wind Energy is supplied directly from third-party wind farms to your facility through the existing transmission network. You don’t need to set up or maintain any physical infrastructure.

Open Access Wind Energy allows commercial and industrial consumers to purchase renewable wind power directly from wind farms through open access regulations. It helps reduce electricity costs and carbon footprint while ensuring a reliable green energy supply.

We plan installations around your business hours. Night shifts, weekend work, phased installations – whatever minimizes disruption. Your business continuity is our priority.
