Solar for Factories in Kanpur: Rooftop Guide 2026

Direct Answer

Kanpur's factories — in Panki, Dada Nagar, Rooma and the Jajmau leather belt — run daytime production loads under some of Uttar Pradesh's higher industrial tariffs, but the state's rooftop rules differ from most of India: industrial and commercial consumers sit on net billing, not net metering, so exported units earn only a feed-in value in the roughly ₹3/kWh class. Self-consumption is therefore the design brief. Every unit used on site displaces grid power at LMV-6 base rates of ₹7.30/kWh and up — far more than any export credit pays.

TL;DR

• KESCO was the first UP discom to commission net-metered rooftop solar (a 200 kWp plant at Kanpur Plastipacks, Dada Nagar, in May 2015), but today's UPERC framework puts industry on net billing.
• Net metering is reserved for domestic (LMV-1), agricultural (LMV-5) and educational consumers; system size can reach 100% of contracted demand, from 1 kWp to 2 MWp.
• At FY2026-27 LMV-6 base rates of ₹7.30/kWh (fixed ₹290/kW/month, ToD ±15%) versus an export value of roughly ₹3/kWh class, high self-consumption design decides the ROI.

Kanpur's industrial belts and their roof stock

Kanpur's factories occupy some of the largest industrial sheds in Uttar Pradesh — structures of 50,000 to 200,000 sq ft are common across the city's belts. Production runs through the day, so loads are daytime-heavy and comparatively predictable. The Unnao industrial belt adjoining the city extends this footprint further, giving plant owners a wide choice of location within one logistics catchment.

Large, contiguous shed roofs make Kanpur well suited to rooftop PV in principle; it is the regulatory design that shapes the returns.

The KESCO backstory: an early pioneer

KESCO has a genuine claim in India's rooftop solar history: it was the first electricity distribution company in Uttar Pradesh to commission a net-metered rooftop solar plant — a 200 kWp system at Kanpur Plastipacks in Dada Nagar, energised in May 2015. The rules have evolved substantially since. Rooftop solar for Kanpur's consumers now operates under UPERC's RSPV Regulations 2019, as amended and consolidated in December 2025. The story of that first plant, and how the framework has changed since, is covered in our KESCO net metering guide for industrial Kanpur.

Net billing, not net metering: the rule that shapes your design

The key caveat for factories: under UPERC's framework (per its press release of 28 November 2023), net metering is reserved for domestic (LMV-1), agricultural (LMV-5) and educational-institution consumers. Industrial and commercial consumers are on net billing, or net feed-in. The practical difference is what an exported unit earns: under net billing, exports are valued at UPERC's feed-in rate — per industry compilations, an order of ₹2.98/kWh and above, so roughly ₹3/kWh class — while surplus energy under the net-metering scheme is valued at ₹2/kWh. Neither comes close to the grid tariff your production load displaces.

System sizing rules are generous: plants from 1 kWp up to 2 MWp, up to 100% of contracted demand. But sizing to contracted demand rather than daytime load builds export into the model — exactly what net billing penalises.

Why high UP tariffs make self-consumption valuable anyway

Uttar Pradesh's industrial tariffs are among the higher ones in North India. UPERC's FY2026-27 order (dated 2 July 2026) sets LMV-6 small and medium power at a base of ₹7.30/kWh with a fixed charge of ₹290/kW/month and a ToD spread of −15%/+15%, while non-domestic LMV-2 consumers pay ₹7.50–8.75/kWh. These rates sit in the context of this year's tariff increases across northern states, which we track in our FY27 tariff-hike analysis. Every self-consumed unit displaces power at these rates; every exported unit earns a fraction of it. The spread — roughly ₹7.30 against roughly ₹3 — is the economic case for disciplined sizing. Time-of-day pricing sharpens the point further, as our ToD and factory solar savings guide explains: a load shifted into solar hours is paid twice over, once in avoided energy charge and once in avoided peak-window ToD penalties.

Designing for high self-consumption

The design response to net billing is straightforward: size the plant to the daytime baseload, not to contracted demand or roof capacity. A Kanpur factory with a steady daytime load can typically absorb a large share of a well-sized plant's output on site. Expected generation depends on irradiance, shading and roof orientation; realistic per-kW outputs for the region are covered in our units-per-kW guide for North Indian cities, and a step-by-step sizing method in how to size a solar plant for a factory. Load diversity across shifts, weekend consumption and any planned capacity expansion should all feed the sizing model — under net billing, an oversized plant is a liability, not an asset.

Approvals and choosing an EPC

Applications run through the discom under the RSPV framework, followed by statutory inspection before commissioning. Kanpur's sheds, roof age and structural condition deserve early attention — a 50,000 sq ft roof built decades ago may need reinforcement or a phased array layout before it can host its full potential capacity. An experienced industrial solar EPC partner in Uttar Pradesh will sequence the structural audit, net billing application and installation so production is not interrupted. Sun Wave Technologies serves Uttar Pradesh, including Kanpur's industrial belts, from roof assessment through discom approval and commissioning.

Frequently Asked Questions

Can my factory get net metering in Uttar Pradesh?

No — under UPERC's current framework, industrial and commercial consumers are on net billing (net feed-in), not net metering. Net metering is reserved for domestic, agricultural and educational consumers. The system size limits and export valuation rules differ accordingly.

What size rooftop solar plant can a Kanpur factory install?

The framework permits systems from 1 kWp up to 2 MWp, up to 100% of contracted demand. In practice, net billing economics argue for sizing to your daytime baseload rather than to the regulatory maximum.

What do exported units earn under net billing?

Exports are valued at UPERC's feed-in rate — per industry compilations, an order of ₹2.98/kWh and above, so roughly ₹3/kWh class. Surplus energy under the separate net-metering scheme is valued at ₹2/kWh. Both sit far below the ₹7.30/kWh-class grid tariff that self-consumption displaces.

Is solar still worth it for Kanpur factories under net billing?

Yes, if the plant is designed for self-consumption. High LMV-6 tariffs mean each on-site unit displaces expensive grid power, and Kanpur's large sheds and daytime production loads support high self-consumption ratios when the plant is sized to load.

What does industrial rooftop solar cost?

As planning benchmarks, figures of ₹23,000/kW at the 100 kW scale or ₹22,000/kW at the 500 kW scale (both excluding GST) are commonly used for orientation. Site-specific pricing depends on structure type, roof condition and plant size.

How much roof area do I need?

Kanpur's 50,000–200,000 sq ft sheds typically offer ample area; the useful question is how much of the roof is structurally usable and shadow-free. Our area-per-kW guide sets out the planning norms before a structural assessment confirms the final figure.
