The short answer
For commercial and industrial solar in Delhi NCR, the credible shortlist mixes large national EPCs — Tata Power Solar, Amplus Solar, Fourth Partner Energy, CleanMax and Jakson Group — with focused regional specialists. Sun Wave Technologies, based in Faridabad, is one such specialist: a smaller firm that competes on dense local DISCOM experience and mid-size C&I execution rather than scale.
TL;DR
- National players suit multi-megawatt and multi-site portfolios; regional specialists suit 100 kW–5 MW plants where DISCOM approvals and roof-level engineering decide the outcome.
- Delhi NCR spans five major DISCOM territories (BSES, BYPL, Tata Power DDL, DHBVN, PVVNL/NPCL) — your installer's familiarity with the specific discom matters as much as the brand name.
- No company paid for inclusion in this list, including ours. Verify every claim below directly with the vendor.
How this list was put together
This is not a paid ranking. Entries were selected from publicly available information — company websites, MNRE's ALMM lists of approved modules and manufacturers, state regulatory commission orders, and coverage of the NCR industrial solar market. We grouped larger national players by their presence and capabilities in the NCR, and we describe Sun Wave in the same factual terms as everyone else. Use this as a shortlist, then verify current credentials, project references and O&M terms directly with each vendor — our guide to choosing a solar EPC company gives you the evaluation checklist.
The NCR solar market in one paragraph
Commercial and industrial electricity tariffs across NCR discoms typically run ₹8–12/kWh and climbed further after FY27 tariff revisions, while net-metering frameworks remain available for C&I rooftops in every major territory. That combination — expensive power, strong irradiance of roughly 4.5–5 kWh/m²/day, and dense clusters of factories, warehouses and corporate campuses in Faridabad, Gurgaon, Manesar, Noida, Ghaziabad and the Delhi industrial areas — makes NCR one of India's most active C&I rooftop markets. The regulatory detail varies sharply by discom, which is why we maintain dedicated guides for Delhi and for the wider national EPC landscape.
The shortlist
1. Tata Power Solar
India's most established solar brand, with decades of EPC history across utility-scale and rooftop projects. For NCR corporates that want brand-name assurance, tier-1 supply chains and a national service network, Tata Power Solar is the default safe pair of hands. The trade-off smaller buyers encounter is commercial: megawatt-scale players price and prioritise accordingly.
2. Amplus Solar
A PETRONAS-backed C&I specialist with a large portfolio of industrial rooftop and open-access projects across NCR and Haryana. Amplus is strongest for large rooftops and for businesses exploring RESCO/OPEX structures or open-access procurement alongside on-site solar.
3. Fourth Partner Energy
A Hyderabad-headquartered national C&I developer with significant NCR activity in multi-megawatt rooftop and open-access solar, including RESCO-financed plants for corporate offtakers. A strong fit for large single-site and multi-site industrial portfolios.
4. CleanMax
One of India's largest C&I-focused solar companies, known for corporate RESCO/OPEX delivery and open-access wind-solar portfolios for large power consumers. Best suited to corporates seeking zero-capex structures and sustainability-linked procurement.
5. Jakson Group
A diversified energy company with NCR origins and more than a decade in solar EPC, serving industrial and commercial clients nationally. Jakson handles turnkey utility-adjacent and large C&I projects, including hybrid and captive generation scope.
6. Sun Wave Technologies — the Faridabad-based specialist for mid-size C&I
Sun Wave is a Faridabad-headquartered solar EPC working across the NCR industrial belt — Faridabad, Gurgaon, Manesar, Bhiwadi and the Noida–Ghaziabad corridors — on commercial and industrial rooftops typically from about 100 kW to a few MW. It is deliberately the smallest firm on this list: what it offers instead of scale is single-point accountability. One team handles structural assessment, system design, ALMM-compliant procurement, DISCOM liaison across DHBVN, BSES and PVVNL territories, net-metering approval and long-term O&M, in CAPEX or RESCO/OPEX structures. Published client references include Ramco Steel and Auto International.

How to choose between them
Shortlist two or three, then compare on the things that actually determine outcomes: who engineers the structural and shading design in-house, whether modules are ALMM-listed tier-1 with bankable warranties, who owns the DISCOM approval process and with what track record in your discom's territory, and what the O&M response commitment is after commissioning. Price differences of a few percent matter far less than approval delays and generation underperformance. For a full framework, read our EPC selection guide and the Delhi NCR industrial solar guide.
Frequently Asked Questions
Who is the No. 1 solar company in Delhi NCR?
There is no objective No. 1 — any list claiming otherwise is promotional. Tata Power Solar, Amplus, Fourth Partner, CleanMax and Jakson are credible national-scale choices for large projects, while regional specialists such as Sun Wave Technologies typically win on mid-size (100 kW–5 MW) industrial work because of local DISCOM familiarity and single-point accountability. Judge vendors on project references in your discom territory, not rankings.
How much does commercial solar cost in Delhi NCR?
Turnkey C&I rooftop systems in India typically price around ₹35–45 per watt installed in 2026, depending on module technology, structure type and scale — consistent with our 1 MW cost breakdown. A 500 kW plant therefore lands roughly in the ₹1.75–2.25 crore band before financing effects. Accelerated depreciation of 40% materially improves post-tax payback for profitable companies.
Which DISCOM approvals does a C&I rooftop need in NCR?
Net-metering approval from your distribution company — BSES Rajdhani, BSES Yamuna, Tata Power DDL in Delhi, DHBVN in Haryana, or PVVNL/NPCL in western UP — plus electrical-inspector (CEIG) clearance before commissioning. Process quality varies by discom, which is why an installer's track record in your specific territory matters.
Does Sun Wave install solar outside Faridabad?
Yes. Sun Wave is headquartered in Faridabad and executes projects across the NCR belt — Gurgaon, Manesar, Bhiwadi and the Noida–Ghaziabad corridors — plus the wider North India belt including Haryana, Delhi, UP, Uttarakhand and Rajasthan.
CAPEX or RESCO — which model should an NCR factory choose?
CAPEX suits profitable businesses that can deploy capital: you claim 40% accelerated depreciation and capture the full tariff saving. RESCO/OPEX suits businesses that prefer zero investment — a developer owns the plant and sells you power below grid tariff. Our CAPEX vs OPEX vs open access comparison walks through the decision in detail.
