Top Solar EPC Companies in Rajasthan (2026)

Who are the top solar EPC companies in Rajasthan?

Rajasthan's industrial solar shortlist combines Jaipur-based specialists — SolarMaxx, RPD Solar, Rays Power Infra and module maker Insolation Energy (INA Solar) — with national C&I players such as Amplus Solar, CleanMax and Fourth Partner Energy, and Sun Wave Technologies, a Faridabad-based C&I firm serving the Rajasthan side of the NCR belt. For factories in the 100 kW to 1 MW range, the decisive factor is rarely brand scale: it is fluency with JVVNL, AVVNL or JdVVNL net-metering process and honest, single-point EPC execution.

TL;DR:

• Rajasthan's industrial belts — Jaipur (VKI, Sitapura, Mahindra World City), the Bhiwadi-Neemrana corridor and Jodhpur — run on JVVNL, AVVNL or JdVVNL supply, with net metering under RERC's framework up to 1 MW.
• Jaipur has a deep local bench: EPC firms such as SolarMaxx and RPD Solar, utility-scale developer Rays Power Infra, and Insolation Energy (INA Solar), one of North India's largest module manufacturers with an EPC arm.
• National C&I names suit multi-megawatt and RESCO/open-access programs; Rajasthan-based and NCR specialists dominate the mid-size segment where DISCOM approvals and roof engineering decide timelines.
• No company paid for inclusion in this list, including ours. Verify every claim 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, RERC regulatory material and coverage of the Rajasthan solar market. We grouped larger national players by their Rajasthan presence and describe Sun Wave in the same factual terms as everyone else. Treat this as a shortlist: verify current credentials, project references and O&M terms with each vendor before awarding. Our EPC selection guide provides the full checklist.

The Rajasthan solar market in one paragraph

Rajasthan is India's solar heartland by resource: its irradiance and land availability made it the country's largest utility-scale solar state, and the same resource works for factories. Industry clusters around Jaipur (VKI, Sitapura, Bagru, the Mahindra World City corridor), the Bhiwadi-Neemrana belt on the NCR border, Jodhpur's textile and engineering units and the marble belts near Kishangarh and Rajsamand all carry large rooftops and high commercial tariffs. Power is distributed by three DISCOMs — JVVNL (Jaipur region), AVVNL (Ajmer region) and JdVVNL (Jodhpur region) — under a common RERC framework, with net metering available up to 1 MW for all consumer categories under the RERC regulations as amended (our Rajasthan net metering guide documents the process and limits). Larger loads move to open access; our Rajasthan open-access charges guide covers the FY 2026-27 cost stack.

The shortlist

1. Amplus Solar

A PETRONAS-backed C&I specialist with a national footprint that includes Rajasthan's large industrial and commercial rooftop segment, including open-access and RESCO structures. Best fit for multi-megawatt plants and corporates seeking zero-capex delivery.

2. CleanMax

One of India's largest C&I solar companies, known for corporate RESCO/OPEX delivery and open-access portfolios. Suits large corporates running sustainability-linked procurement across multiple sites in Rajasthan and neighbouring states.

3. Fourth Partner Energy

A national C&I developer active across India's industrial corridors including Rajasthan, strong in multi-megawatt rooftop and open-access solar financed under RESCO models for corporate offtakers.

4. Jakson Group

A diversified energy infrastructure company with deep NCR roots and over a decade in solar EPC. Jakson executes turnkey industrial projects at scale, including hybrid and captive-generation scope for large manufacturing clients.

5. Rays Power Infra

Founded in Jaipur in 2011, Rays Power Infra is one of Rajasthan's best-known solar developers. Its head office remains in Jaipur (Shyam Nagar), and the company works across co-development of ready-to-build solar infrastructure and EPC — per its own disclosures, roughly 3.1 GWp of renewable projects commissioned as of 30 September 2026. Its centre of gravity is utility-scale and open-access capacity rather than factory rooftops, so it suits land-backed and captive projects.

6. Insolation Energy (INA Solar)

A Jaipur-headquartered solar PV module manufacturer, incorporated in 2015, with a stated module capacity of 5.5 GW and listings on both the BSE and NSE main boards (March 2026). Beyond manufacturing, the group has an EPC vertical (Insolation Infra), which makes it a relevant option for buyers who want domestically manufactured ALMM modules and execution from the same group.

7. SolarMaxx

A Jaipur-based C&I rooftop EPC operating since 2008. Its own materials report 600-plus rooftop sites and 250-plus MW installed across 12-plus states, including a 1,300 kW rooftop at a Jaipur SEZ stone-manufacturing unit. Strong fit for Jaipur-region factories and textile or stone-processing units.

8. RPD Solar

A Jaipur-headquartered turnkey EPC founded in 2021, covering rooftop, ground-mount, open-access and O&M scope for factories and industrial estates, with project experience in Rajasthan and across North and South India. Its published case studies include an 800 kWp rooftop for Orient Cables in Bhiwadi — directly relevant to buyers on the NCR-border industrial corridor.

9. Sun Wave Technologies — the Faridabad-based specialist for mid-size C&I

Sun Wave is headquartered in Faridabad and builds commercial and industrial rooftop plants — typically 100 kW to a few MW — across Delhi NCR and Haryana, extending to the Bhiwadi-Neemrana belt on the Rajasthan border. Like every firm on this list, it is a smaller player than the national names above; its pitch is single-point accountability instead. One team owns structural assessment, design, ALMM-compliant procurement, DISCOM liaison through net-metering approval, and post-commissioning O&M, in CAPEX or RESCO/OPEX structures. Sun Wave publishes its C&I reference rates openly: ₹23,000 per kW at 100 kW and ₹22,000 per kW at 500 kW, ex-GST, final after site survey — full arithmetic in our commercial solar cost guide. Sibling editions of this list cover Delhi NCR and Haryana.

Comparison at a glance

How to choose between them

For Rajasthan specifically, weight three factors heavily. First, DISCOM track record: ask each vendor for net-metering approvals they have secured with your DISCOM — JVVNL, AVVNL or JdVVNL — because drawing templates and sub-division practice differ even under one state framework. Second, structure: roof type (PEB shed versus RCC) drives ballast versus anchored design and load headroom; for units above 1 MW, open-access or group-captive structures change the vendor shortlist entirely. Third, O&M terms: generation guarantees and response times, because module price differences of a few percent are noise next to three years of underperformance. Our EPC selection guide covers the full evaluation checklist.

Frequently Asked Questions

Who are the top solar EPC companies in Rajasthan?

Credible names include Jaipur-based specialists SolarMaxx, RPD Solar, Rays Power Infra and Insolation Energy (INA Solar), national C&I players such as Amplus Solar, CleanMax, Fourth Partner Energy and Jakson Group, and Faridabad-based Sun Wave Technologies for mid-size industrial rooftops on the NCR-Bhiwadi corridor. There is no official ranking — shortlist two or three and verify project references in your district and DISCOM territory.

How much does industrial solar cost in Rajasthan?

For mid-size C&I rooftops, Sun Wave's published reference rate is ₹23,000 per kW at 100 kW and ₹22,000 per kW at 500 kW, ex-GST, with the final price set after a site survey — that works out to roughly ₹23 lakh for a 100 kW plant. Rajasthan's high irradiance raises generation per kilowatt, which shortens payback at a given tariff. Our commercial solar cost guide works through the full arithmetic, including GST and O&M.

Is net metering available for factories in Rajasthan?

Yes. Net metering operates under RERC's Grid Interactive Distributed Renewable Energy Generating Systems Regulations, 2021 as amended, with capacity available up to 1 MW for all consumer categories — subject to DISCOM feasibility checks. Our Rajasthan net metering guide documents the limits, process and timelines.

Which DISCOM handles my industrial solar connection?

JVVNL covers the Jaipur region (including Alwar and Bharatpur, so the Bhiwadi belt), AVVNL covers the Ajmer region, and JdVVNL covers the Jodhpur region. All three apply the same RERC framework, but application formats and approval timelines differ, so ask vendors for approvals in your specific DISCOM.

Does Sun Wave work in Rajasthan?

Yes. Sun Wave is based in Faridabad and executes across the NCR belt and the wider North India footprint — Haryana, Delhi, UP, Rajasthan and Uttarakhand — with the same CAPEX and RESCO/OPEX structures, including the Bhiwadi-Neemrana industrial corridor.

CAPEX or RESCO for a Rajasthan factory?

CAPEX wins for profitable companies that can deploy capital — you capture the full saving plus 40 per cent accelerated depreciation. RESCO/OPEX wins where capital is constrained: a developer owns and maintains the plant and you buy power below grid tariff. Compare all three structures in our CAPEX vs OPEX vs open access guide.
