Commercial & Industrial solar rooftop

Commercial & Industrial Solar

Drive down energy costs, lock predictable long-term tariffs, and meet ESG commitments with bankable rooftop and open-access solar. Choose CAPEX or OPEX/RESCO, optimize TOD peaks, and gain reliable yields through CEIG/CEA-compliant engineering, performance monitoring, and streamlined statutory approvals.

Mounting Options for C&I Roofs

Engineered for large spans, wind loads and minimal roof penetration.

RCC roof structuresRCC ROOF

RCC Ballast / Anchor

Optimized tilt, weight distribution, and walkways for easy O&M on flat RCC roofs.

Sheet roof structuresSHEET ROOF

Klip-Lok / Standing Seam

Non-penetrating clamps or weather-sealed fasteners with load checks for PEBs.

Solar carportCARPORT

Parking Carports

Utilize parking areas for generation with integrated drainage and EV-ready cabling.

Commercial Models & Financing

Select an approach that fits your balance sheet and risk appetite.

CAPEX ownership

CAPEX — You Own

Highest IRR, AD benefits, full control over assets and O&M.

OPEX RESCO

OPEX/RESCO — Pay per kWh

Zero upfront; energy billed via long-term PPA at tariff discount.

Tax & accounting benefits

AD & Tax Efficiency

Accelerated Depreciation and input credits (as applicable) improve post-tax IRR.

Peak saving & TOD Optimization

Design for day-time peaks, reduce TOD surcharges and demand charges.

Compliance & Safety

CEIG/CEA compliant design, protection study, and statutory documentation.

Sustainability Targets

Meet RE100/ESG goals and reduce Scope-2 emissions with auditable data.

Tax & Accounting Benefits

Accelerated Depreciation and GST input credit where applicable.

How It Works

We analyze your energy profile, TOD slabs, and contract demand, then survey roof strength, waterproofing, and shading. The outcome is a practical layout and capacity that fits operations, safety, and maintenance access requirements.

You receive generation simulations with PR assumptions, side-by-side CAPEX and OPEX cash flows, tariff comparisons, IRR, and payback. We also outline interconnection options and risks, so stakeholders decide confidently with transparent numbers.

Our team manages utility feasibility, net or gross metering applications, and CEIG/CEA safety submissions. Where needed, we coordinate fire-safety norms, earthing tests, and documentation to ensure statutory compliance without internal effort.

We finalize structural design, select Tier-1 PV modules, inverters, protection schemes, cables, earthing, and lightning arrestors. Procurement follows approved makes, ensuring availability, warranties, and project timelines remain predictable for execution.

Experienced crews install structures and electrical systems with QA/QC checkpoints. Pre-commissioning includes insulation checks, relay settings, and synchronization tests, ensuring safe operation and reliable performance under expected grid conditions.

We commission SCADA/RMS for live monitoring, hand over documentation and training, and set SLAs for uptime. Preventive maintenance schedules and performance dashboards keep yields consistent and deviations quickly addressed throughout lifecycle.

FAQs

What business models are available (CAPEX vs OPEX/RESCO)?

CAPEX: you invest and own the system; highest IRR and full control. OPEX/RESCO: developer invests and sells energy at a tariff via PPA; zero upfront but lower long-term savings vs CAPEX.

What savings can C&I expect?

Typical rooftop saves 20–50% against grid tariffs depending on your slab, TOD, sanctioned load and rooftop potential. Open-access offsite can save more for large consumers.

Are approvals different from residential?

Yes. C&I often require CEIG/CEA safety compliance, internal electrical inspection, earthing tests, fire NOC in some states, and utility approvals for synchronization/net-metering or gross-metering.

What about Accelerated Depreciation (AD)?

Under income-tax provisions (as per prevailing rules), eligible entities can claim accelerated depreciation on solar assets to improve post-tax IRR. Consult your tax advisor for current rate applicability.

Is net metering allowed for industries?

Most states allow C&I net or gross metering with kW caps and conditions (transformer capacity %, contract demand limits). Policies vary—final design follows your state’s regulation.

Battery/Hybrid options?

For critical loads, hybrid (solar + battery + grid/DG) ensures backup and peak-saving. Batteries don’t usually qualify under rooftop subsidy; deployed on case-to-case business ROI.
