Solar Installation in Gurugram: Industrial Rooftop Guide 2026

Sun Wave Technologies16 July 20268 min read

Gurugram — covering IMT Manesar, Udyog Vihar, Sector 18 and the Sohna industrial belt — is one of Delhi-NCR's highest-tariff industrial markets for rooftop solar. Power here is supplied by DHBVN under HERC's HT industrial tariff, net metering is available up to 500 kW or sanctioned load (whichever is lower), and the combination of high grid tariffs and Sun Wave Technologies' Faridabad-headquartered local coordination makes rooftop solar a 3.5–4.5-year payback for most IMT Manesar and Udyog Vihar factories.

Key Takeaways

  • DISCOM: DHBVN (Dakshin Haryana Bijli Vitran Nigam) for Gurugram and IMT Manesar; HT supply above 50 kW.
  • Net metering: up to 500 kW or sanctioned load/contract demand, whichever is lower; net billing 500 kW–1 MW; 1–2 MW needs 25% / 2-hour battery storage. See our DHBVN net metering guide.
  • Industrial hubs: IMT Manesar (auto Tier-1s), Udyog Vihar (engineering, electronics), Sohna/Bawal corridor, Cyber City-adjacent commercial blocks.
  • EPC cost (2026): ~₹3.4–3.9 Cr per MW for industrial rooftop with ALMM Tier-1 modules; RESCO PPA ~₹4.0–5.0/kWh.
  • Payback: 3.5–4.5 years on CAPEX against DHBVN HT tariffs; faster with accelerated depreciation.
  • Gurugram is an active Sun Wave service region with same-day site visits from the Faridabad HQ.

Why Gurugram is a strong market for industrial solar

Gurugram's industrial tariff sits among the highest in North India, its auto and engineering clusters run heavy daytime loads that match solar generation, and many factories supply to multinationals carrying ESG/supplier-sustainability mandates that rooftop solar directly satisfies. Sun Wave Technologies, headquartered in Faridabad and a leading solar EPC company in India, serves Gurugram as an active region with direct local coordination — see our Haryana EPC company guide.

DHBVN HT industrial tariff and solar savings in Gurugram

Under HERC's tariff schedule (most recent order applicable to FY 2026-27, building on the FY 2025-26 schedule approved 28 March 2025), HT industrial supply in the DHBVN area is billed on a kVAh energy charge plus a fixed charge per kVA of contract demand per month, with voltage-based slabs (11 kV / 33 kV / 66–132 kV). The schedule excludes electricity duty, municipal tax and FSA, which are added per state notification. For context, the FY 2025-26 schedule set HT supply at 11 kV around ₹6.65/kVAh plus ₹290/kVA/month, with 33 kV and 66/132 kV slabs lower on the energy charge.

Tariff component (HT industrial, DHBVN)Indicative treatment
Energy charge (11 kV)~₹6.6–7.0/kVAh (verify against the live HERC order)
Fixed charge~₹290/kVA of contract demand per month
Add-onsElectricity duty, municipal tax, FSA (per state notification)
Open-access surcharge (if applicable)additional surcharge per HERC order; captive own-use exempt

Rooftop solar displaces the energy-charge portion during daytime generation, which is the largest line on most HT industrial bills. Because HT tariffs in Gurugram are materially above the ~₹3.5–4.0/kWh levelised cost of rooftop solar, the arbitrage is strong. Model your specific case with our savings calculator and the solar payback guide.

Always validate the exact tariff slab, fixed charge, FSA and duty against the current HERC tariff order and your facility's latest DHBVN bill before building a business case.

Net metering for Gurugram industrial consumers

DHBVN processes net metering for Gurugram through its rooftop solar portal. Key parameters:

ParameterValue
Net metering cap500 kW or sanctioned load/contract demand, whichever is lower
500 kW–1 MWNet billing
1–2 MWNet billing + 25% / 2-hour battery storage
Application fee₹1,000 (up to 100 kW); ₹5,000 (100 kW–1 MW)
Typical approval timeline30–45 days application to meter
Cumulative transformer cap50% (LT) / 30% (HT) of local distribution transformer capacity

Sun Wave handles the complete DHBVN application — documents, technical feasibility, post-installation inspection and bidirectional meter installation — as part of every EPC and RESCO engagement. Full process in our DHBVN net metering application guide.

Industrial hubs in Gurugram and IMT Manesar

IMT Manesar

Premium auto-manufacturing cluster and Tier-1 supplier ecosystem for Maruti Suzuki, Hero MotoCorp, Honda and others. Typical rooftop loads 200 kW–3 MW per facility. Strict building codes mean the solar design must comply with IMT regulations; DHBVN grid connectivity is reliable. Many factories supply to multinationals carrying ESG compliance — solar helps meet supplier sustainability mandates. See our solar for automotive industry guide.

Udyog Vihar

Mixed engineering, electronics and light manufacturing near the Delhi border. 100–1,000 kW per facility, mostly RCC roofs with adequate structural capacity.

Sohna / Bawal corridor

Growing manufacturing and logistics belt along the NH-48 / NH-19 axis. See our Manesar-Bawal-Bhiwadi guide and logistics & warehousing guide.

Commercial blocks (Cyber City-adjacent)

Offices, hotels and malls with connected load ≥ 50 kW are covered by Haryana's commercial solar mandate — see our Haryana commercial building solar mandate guide.

EPC cost and RESCO in Gurugram (2026)

For a 1 MW industrial rooftop EPC with ALMM Tier-1 modules, string inverters, HDG structures and 1-year free O&M, expect roughly ₹3.4–3.9 Cr per MW (₹35,000–45,000/kW for smaller systems), consistent with our solar EPC cost per MW guide. RESCO/OPEX is fully DHBVN-supported:

  • Zero capex; immediate 20–35% savings vs DHBVN HT tariff
  • PPA rate: ~₹4.0–5.0/kWh
  • PR guarantee: typically ≥ 78% Year 1
  • Buy-out option from Year 7

Compare models in our CAPEX vs OPEX vs Open Access guide and RESCO/OPEX guide.

Approvals and compliance for Gurugram solar

  • DHBVN net metering — primary approval; see above.
  • Fire NOC — typically required for systems above 500 kW in Haryana.
  • CEI approval — Chief Electrical Inspector approval for HT connections.
  • HSPCB — Haryana State Pollution Control Board does not require an NOC for solar, but installation supports environmental compliance.
  • Municipal approval — generally not required for rooftop solar on existing industrial buildings, but IMT Manesar building codes should be checked.
  • Structural sign-off — required; see our wind-uplift and load-path audit.

FAQ

Which DISCOM handles Gurugram industrial solar?

DHBVN (Dakshin Haryana Bijli Vitran Nigam) handles all net-metering applications for industrial consumers in Gurugram and IMT Manesar. Approval typically takes 30–45 days; Sun Wave handles the complete process.

Is net metering allowed for industrial consumers in Gurugram?

Yes. Under HERC's Rooftop Solar Regulations, 2021 (as amended), net metering is allowed up to 500 kW or sanctioned load/contract demand, whichever is lower. Systems of 500 kW–1 MW use net billing; 1–2 MW systems must include 25% / 2-hour battery storage.

How much does industrial solar cost in Gurugram in 2026?

A 1 MW industrial rooftop EPC costs roughly ₹3.4–3.9 Cr; smaller systems run ₹35,000–45,000/kW. RESCO is available at ~₹4.0–5.0/kWh with zero capex. See our EPC cost per MW guide.

What is the payback for industrial solar in Gurugram?

Typically 3.5–4.5 years on CAPEX against DHBVN HT tariffs, faster with accelerated depreciation. See our solar payback guide and tax benefits guide.

Can I install solar on an IMT Manesar factory?

Yes. IMT Manesar has strong DHBVN grid connectivity and mostly RCC-roofed buildings with adequate structural capacity. Strict building codes mean the design must comply with IMT regulations; Sun Wave handles this as part of the EPC scope. Typical system sizes are 200 kW–3 MW per facility.

Does Gurugram fall under Haryana's commercial solar mandate?

Yes — commercial buildings (offices, malls, hotels) with connected load ≥ 50 kW must install 3–5% of connected load as rooftop solar. See our Haryana commercial building solar mandate guide.

Should Gurugram industrial buyers include BESS?

Not automatically. HERC has continued an optional off-peak concession for incremental consumption but is reviewing the scheme. Size BESS only after reviewing interval load data, contract-demand peaks, outage losses, DG runtime and the current DHBVN ToD circular. See our DG vs BESS comparison and NCR solar+BESS business case.
