An EPC founder who spends ₹80,000 to ₹1.5 lakh attending an expo (registration, travel, accommodation and collateral) needs signed pipeline within about 90 days to justify the spend. India’s renewable energy expo calendar runs 10+ significant events per year, but they are not equally valuable for every business type, and most attendees leave without a structured approach to converting contacts into revenue.
This guide, written for EPCs and installers, covers the Renewable Energy India Expo and the other major renewable energy expos with a business-first lens: what each event delivers, who attends, and how to apply the Expo-to-Pipeline (E2P) Framework to turn two days on the floor into qualified project pipeline.
Quick answer. Renewable Energy India (REI) Expo, held each year at India Expo Centre and Mart, Greater Noida, is India’s largest renewable energy trade show, with 600+ exhibitors and 50,000+ visitors. Other major solar expos in India are Intersolar India in Gandhinagar and Smart Energy India Expo in New Delhi. Confirm each year’s dates on the organiser’s site.
This guide covers the events, the E2P Framework, and what Heaven Designs can put in your hands before you walk the floor.
TL;DR
- REI Expo (Greater Noida) is India's largest show and the best for B2B project pipeline; Intersolar India (Gandhinagar) is the best venue for technical and module intelligence; Smart Energy India (Delhi) is the best for policy and DISCOM contacts.
- The Expo-to-Pipeline (E2P) Framework turns floor time into qualified leads through pre-expo targeting, on-floor qualifying questions, and a 48-hour project-specific follow-up.
- Regional expos (Bharat Solar Expo, EPS Expo, Solar Plus Energy World and the city-specific shows) often deliver higher-quality leads per rupee for EPCs concentrated in a single state.
- Exhibiting (taking a booth) generally only pays off for larger EPCs; most founders get better ROI attending as a visitor with a structured follow-up plan.
- Physical sample deliverables (GA, SLD, BOQ, PVsyst yield estimates) usually outperform brochures at converting expo conversations into signed projects.
Why Renewable Energy Expos Matter for Indian EPCs in 2026
India’s target of 500 GW of non-fossil capacity by 2030 (see MNRE) needs a much larger EPC supply chain than exists today.
That expansion happens at expos. Module manufacturers launch new products, DISCOM officials announce procurement windows, SECI representatives explain upcoming auction structures, and financiers present lending program updates, all on the expo floor.
For an EPC founder running 5-20 projects per month, expos serve four distinct business functions:
- Lead generation: Meeting developers, industrialists, and DISCOM representatives who need EPC services and have no existing engineering partner relationship.
- Technology intelligence: Assessing new module, inverter, and mounting technology before committing it to a project BOQ.
- Competitive intelligence: Observing what other EPC companies are offering, how they position their services, and what pricing is standard in the market.
- Supply chain development: Meeting potential subcontractors, equipment suppliers, and strategic partners who can extend your geographic or technical capabilities.
Definition. B2B pipeline developed at an expo refers to qualified business leads (companies or individuals with a specific, funded project need and the authority to award work) who were identified, qualified, and entered into a CRM follow-up sequence during or immediately after the event. Unqualified contact cards with no follow-up protocol are not pipeline; they are business card clutter.
According to Mercom India’s 2025 Solar Market Outlook, India’s rooftop solar market is projected to grow from 4.5 GW annually in FY25 to 8-10 GW annually by FY28, with the residential and C&I segments each contributing roughly half.
The Bridge to India Solar Compass further notes that India’s EPC supply chain is undercapacitized relative to the government’s 500 GW target, which makes partnerships formed at expos more valuable. More first-time buyers (homeowners, SME industrial units, commercial complexes) are entering the market through expo channels and need EPC guidance to navigate the process.

Renewable Energy India (REI) Expo, Greater Noida
The REI Expo (Renewable Energy India Expo) is India’s largest dedicated renewable energy trade show, now in its 18th edition. It is organized by Informa Markets at the India Expo Centre & Mart in Greater Noida, Uttar Pradesh, and typically runs for three days in October or November.
Event profile:
- Visitors: 50,000+
- Exhibitors: 600+
- Floor area: 35,000+ m²
- Key exhibitor categories: Solar PV modules, inverters, mounting structures, BESS, EPC services, project finance, O&M
The REI Expo has the highest density of solar sector attendees. The visitor profile spans developers, EPCs, DISCOMs, state renewable energy agencies, industrialists considering captive solar, and institutional buyers (hospitals, educational institutions, government bodies). The exhibitor floor covers the full solar value chain from polysilicon to project finance.
For Heaven Designs clients, REI Expo is the highest-priority annual event. The combination of developer and industrialist visitors (potential project clients) with DISCOM and policy representatives makes it the single best location in India to understand the market direction for the coming 12 months while simultaneously generating qualified leads.
Strategic focus for EPCs: Attend the conference sessions on SECI upcoming auctions and state policy announcements. Bring a project portfolio deck and sample deliverables. Pre-book meetings with module manufacturers whose ALMM listing you are evaluating for upcoming project BOQs.
Intersolar India / Smarter E India, Gandhinagar, Gujarat
Intersolar India operates under the Smarter E India umbrella, a multi-segment expo encompassing solar PV (Intersolar), energy storage (ees India), power electronics (Power2Drive India), and smart energy management (EM-Power India). It is held at Helipad Exhibition Center in Gandhinagar, Gujarat, and typically runs in February.
Event profile:
- Visitors: 15,000+
- Exhibitors: 250+
- International focus: Yes (Germany’s Intersolar brand, strong European manufacturer presence)
- Key feature: Technical conference with IEC, BIS, and MNRE regulatory updates
Intersolar India is India’s most technically rigorous solar expo. The conference program covers cell technology roadmaps, module certification standards, grid integration challenges, and policy updates. European and Chinese module manufacturers use this platform to launch products for the Indian market, often coinciding with announcements of ALMM applications or BIS certification milestones.
For EPCs specifying modules for medium-to-large-scale projects (500 kW and above), Intersolar India is the best venue to compare N-type TOPCon, HJT, and emerging bifacial products from multiple manufacturers in person, including direct answers about ALMM listing status, production traceability certification, and warranty claim processes from manufacturer representatives who have authority to commit.
Strategic focus for EPCs: Prioritize the technical sessions on module efficiency roadmaps and the BIS/ALMM compliance workshop if offered. Bring a specific technology evaluation checklist for the 2-3 module products you are considering for upcoming projects.
Field tip. Before attending any expo, prepare a one-page "project brief card" that summarizes your current project pipeline: system type (rooftop / ground-mount), capacity range, state, timeline, and module / inverter requirements. Handing this to a manufacturer or developer contact replaces 10 minutes of verbal explanation with a 30-second qualifying conversation, allowing you to identify mutual fit or disqualify faster and move on to the next booth.
Smart Energy India Expo, Pragati Maidan, New Delhi
Smart Energy India Expo is part of the Smart Cities India Expo, held at Pragati Maidan in New Delhi, typically in March. It is organized by Exhibitions India Group and targets the intersection of renewable energy, urban infrastructure, and smart city development.
Event profile:
- Visitors: 25,000+
- Exhibitors: 450+
- Key profile: Government agencies, DISCOMs, smart city SPVs, smart grid technology vendors, renewable energy developers
Smart Energy India is the main venue for meeting policy implementers: DISCOM officials, state renewable energy agency representatives and central ministry staff who shape the incentive structures EPCs operate within. The conference program typically includes sessions on DISCOM reform, net metering regulation updates, and state-specific rooftop solar deployment targets.
For EPCs seeking DISCOM empanelment, state nodal agency tie-ups, or government sector project pipeline, Smart Energy India offers direct access to decision-makers who are otherwise difficult to reach through normal sales channels. For EPCs serving government and DISCOM-connected clients, understanding the DISCOM net metering process across Indian states before attending is valuable preparation for policy-focused conversations.
According to SEIA’s global solar deployment analysis, India is now among the top three solar markets globally, which makes international-attended events like Intersolar India increasingly significant for cross-border EPC partnerships.
Bharat Solar Expo, Jaipur Exhibition & Convention Centre
Bharat Solar Expo, now in its third edition, focuses specifically on the solar sector with an emphasis on Rajasthan, Uttar Pradesh, and the broader northern India market. It runs in January at the Jaipur Exhibition & Convention Centre.
Event profile:
- Visitors: 6,000+
- Exhibitors: 120+
- Regional focus: North India, Rajasthan solar belt, agricultural solar (PM-KUSUM)
- Key sessions: Regulatory updates from Rajasthan Renewable Energy Corporation (RREC), DISCOM net-metering procedures, agricultural feeder solar
For EPCs operating in Rajasthan, UP, Haryana or Punjab, particularly those pursuing PM-KUSUM Component B (agricultural solar pumps) and Component C (feeder solarisation) projects, Bharat Solar Expo provides access to state agency representatives and technology suppliers calibrated to the regulatory and climate conditions of northern India.
EPS Expo, Ahmedabad, Gujarat
EPS Expo (Energy, Power, and Solar) is a regional expo focused on the Gujarat, western Maharashtra, and Madhya Pradesh solar market, held at EKA Club Kankaria Ahmedabad in September.
Event profile:
- Visitors: 10,000+
- Exhibitors: 150+
- Regional focus: Gujarat (Waaree, Adani Solar, Goldi Solar home state), BESS, EV charging
EPS Expo is particularly valuable for EPCs headquartered in or operating extensively in Gujarat because of the concentration of module manufacturers in the state: Waaree (Surat), Goldi Solar (Navsari) and Adani Solar (Mundra). See our list of top solar panel manufacturers in India before you plan factory visits. Factory visit invitations from manufacturer sales teams often extend from EPS Expo contacts.
For a sense of how local and national solar EPC companies compete in Gujarat, this state-level manufacturer density is a genuine advantage for locally based EPCs over out-of-state competitors bidding on the same projects.
Solar Plus Energy World Expo, Mumbai, Maharashtra
Solar Plus Energy World Expo focuses specifically on solar + BESS integration, held at NESCO Center Mumbai in November.
Event profile:
- Visitors: 5,000+
- Exhibitors: 50-100
- Technology focus: BESS, hybrid solar, C&I solar + storage, solar microgrids
For EPCs developing C&I and industrial solar projects where battery storage is increasingly part of the scope, Solar Plus provides the most focused audience of BESS technology providers and hybrid system EPCs in India. The targeted scope means higher-quality technical conversations with fewer distractions.
Regional Expos: Chhattisgarh, Chennai, Kochi, and More
Several regional expos serve specific state markets and are worth attending for EPCs with operations in those geographies:
| Expo | Location | Typical Date | Visitors | Primary Value |
|---|---|---|---|---|
| Renewable Energy Expo Chennai | Chennai Trade Centre | February | 9,000+ | Tamil Nadu DISCOM contacts, South India EPC network |
| Chhattisgarh Solar Expo | Shriram Business Park, Raipur | February | 5,000+ | CG state projects, MNRE scheme implementation |
| Solar Asia Expo | Urban Haat, Indore | March | 5,000+ | MP market, C&I industrial buyers, agricultural solar |
| KREEPA Green Power Expo | Adlux Convention Centre, Kochi | November | 1,000-5,000 | Kerala KSEB contacts, rooftop residential South Kerala |
For an EPC whose primary market is one of these states, regional expos often deliver higher-quality leads per ₹ of attendance cost than national events, because the visitor-to-EPC ratio tilts toward prospective buyers rather than industry participants.

The Expo-to-Pipeline (E2P) Framework: Converting Floor Time into Revenue
Many EPC principals attend expos, collect a stack of business cards and convert very few into project discussions. The E2P Framework improves that ratio with a structured cadence before, during and after the event.
Pre-expo (2 weeks before): Set 5 specific objectives and pre-book meetings
Define exactly what success looks like: 3 developer meetings, 2 module manufacturer product reviews, or 1 state agency contact for a specific scheme. Use the expo's attendee or exhibitor list to identify specific targets and email or call them before the event to schedule floor meetings. Pre-booked meetings are far more likely to lead to a follow-up conversation than cold floor encounters.
Preparation: Bring a physical sample deliverable, not just a brochure
A printed or laminated sample SLD and GA drawing from a completed project communicates your engineering quality in 30 seconds. A brochure is forgettable. A project portfolio showing 5 completed projects with photos, system specs, and client logos is remembered. Prepare a one-page project brief card with your current capacity and pipeline so prospects can self-qualify immediately.
During expo: Qualify before collecting, not after
Ask three qualifying questions at every contact: What is the project size or type? What is your timeline? Who makes the final procurement decision? Anyone who cannot answer these questions is not a qualified lead. They are a contact. Separate your business card collection into two groups: qualified (follow up within 48 hours) and networking (follow up within 2 weeks). Do not blend them.
Post-expo (48 hours): Send a project-specific follow-up, not a generic intro
Reference the specific project discussed. Attach a relevant sample deliverable (if their project is a 500 kW rooftop, send a sample GA and SLD for a similarly sized project). Propose a specific next step with a date: "I can share a preliminary scope estimate by Thursday. Does a 30-minute call at 11am work?" A project-specific follow-up with a concrete next step converts far better than a generic "It was great to meet you" email.
Post-expo (30 days): Deliver a pre-design or feasibility estimate for each hot lead
For each hot lead (qualified, interested, has budget), deliver a preliminary [PVsyst yield estimate](/blog/pv-yield-simulation-software/) or 3D shading model within 30 days of the expo. This moves the relationship from "networking contact" to "engineering conversation" and establishes your technical credibility before the formal tender or RFP stage. A [3D pre-design](/solar-3d-pre-design/) built from rooftop photos and coordinates gives you a technical differentiator after an expo contact is qualified. Pairing that yield estimate with a quick generation and payback projection, using a tool such as SurgePV's generation financial tool (a sister product; see the disclosure below), lets you hand a hot lead a ballpark ROI figure in the same follow-up email, rather than waiting for a formal proposal cycle.
Watch out. Many EPC companies build their expo booth around their past project portfolio without a clear mechanism for visitors to understand what they can do for them right now. Prospects are not interested in your history. They are interested in their problem. Reframe your booth messaging from "we built X MW of solar" to "we deliver [specific deliverable] in [specific timeframe] for [specific project type]." A clear service offer beats a vague track record every time on an expo floor.
Upcoming Solar Expos in India 2026: Comparison by EPC Business Type
Not every expo is equally valuable for every EPC profile. Use this matrix to prioritize your annual expo attendance budget:
| EPC Profile | Top Priority Expo | Secondary Expo | Skip If Budget Constrained |
|---|---|---|---|
| Residential rooftop EPC (1-50 kW) | Bharat Solar Expo (regional) | Smart Energy India | REI Expo |
| C&I rooftop EPC (50 kW - 5 MW) | REI Expo | Smarter E India | Regional expos |
| Utility-scale developer (5+ MW) | REI Expo | Smart Energy India | All regional expos |
| EPC seeking BESS capability | Solar Plus Energy World Expo | REI Expo | Regional expos |
| Gujarat-based EPC (any segment) | EPS Expo (home state advantage) | Smarter E India | Bharat Solar Expo |
PROS, ATTENDING EXPOS
- Access decision-makers who are otherwise unreachable through cold outreach
- See new module and inverter products before they launch commercially
- Understand policy changes from DISCOM and agency representatives directly
- Turn more contacts into qualified leads with the E2P Framework
CONS, EXPOS WITHOUT PREPARATION
- ₹80K - ₹1.5L spend per event with no structured follow-up = poor ROI
- Floor time spent with non-qualified contacts instead of decision-makers
- Generic booth presence indistinguishable from 200+ other EPC companies
- No mechanism to convert contacts to pipeline within 30-90 days
How Heaven Designs Helps EPCs Maximize Expo ROI
The primary differentiator for an EPC on an expo floor is engineering credibility: the ability to hand a potential client a tangible demonstration of what working with you produces. Heaven Designs equips EPCs with exactly this differentiation.
- Solar 3D pre-design, a 3D shading model and yield estimate you can offer an expo lead as the next step. This turns a networking conversation into a technical engagement.
- Solar Rooftop Detailed Engineering Design, bring printed sample IFC-grade deliverables to your expo booth: GA, SLD, BOQ. Show what your engineering outputs look like before prospects ask.
- Solar Ground Mount Design, for EPCs targeting utility-scale developers at REI Expo, bring a sample utility-scale layout with a PVsyst yield summary and bankable P50/P90 output.
- Sample deliverables, get a printed-quality sample pack before your next expo. A physical sample deliverable is one of the most effective pieces of collateral an EPC can bring.
- Project Management Consultancy, for EPCs presenting PMC services to developers, a sample owner’s engineer dashboard and monthly progress report format communicates professional project oversight capability.
Contact Heaven Designs to build an expo-ready sample deliverable package for your next event.

FAQ
What is the biggest renewable energy expo in India?
The Renewable Energy India (REI) Expo, organized by Informa Markets at India Expo Centre & Mart in Greater Noida, is India’s largest renewable energy trade show by visitor count (50,000+) and exhibitor count (600+).
Now in its 18th edition, it covers the full solar, wind, and storage value chain and is attended by the widest cross-section of developers, EPCs, manufacturers, financiers, and policy makers of any Indian renewable energy event. For most EPC businesses, REI Expo is the highest-priority annual attendance investment.
When and where is Intersolar India held?
Intersolar India, which operates under the Smarter E India umbrella, is typically held in February at the Helipad Exhibition Center in Gandhinagar, Gujarat. The event combines four segments: Intersolar India (PV), ees India (energy storage), Power2Drive India (EV charging), and EM-Power India (smart energy management).
It is the most technically rigorous solar expo in India, with a conference program covering IEC and BIS certification updates, cell technology roadmaps, and grid integration.
How should an EPC company decide which expos to attend?
Prioritize based on three factors: (1) visitor profile alignment: does the expo attract the type of buyers and developers whose projects match your EPC capabilities? (2) Geographic proximity: a regional expo in your primary operating state often delivers higher-quality leads per rupee than a national expo 1,000 km away. (3) Strategic objectives: if your objective is technology intelligence, Intersolar India outranks REI Expo; if your objective is government sector pipeline, Smart Energy India Expo in Delhi outranks both. Use the comparison matrix in this article to set a prioritized expo calendar.
What should an EPC company bring to a renewable energy expo?
Beyond business cards, bring: (1) a one-page project brief card summarizing your current capacity, project types, and states of operation; (2) a printed or laminated sample deliverable, such as an SLD and GA drawing, from a completed project; (3) a project portfolio document with photos, system specs, and client names (if permissible); (4) a short elevator statement that describes your specific service offer in one sentence, not a vague “we do solar EPC.” Companies that bring physical engineering samples consistently report higher-quality booth conversations than companies with brochures only.
How can Heaven Designs help EPCs prepare for renewable energy expos?
Heaven Designs produces engineering deliverables (SLD, GA, BOQ, PVsyst yield summaries) that EPCs can print and use as demonstration material at expo booths. We also prepare 3D pre-designs that EPCs can offer expo leads as a next step. Request our design samples before your next expo; the pack arrives by email within 24 hours.
Is exhibiting at renewable energy expos worthwhile for EPC companies?
Exhibiting (taking a booth) is usually only cost-effective for larger EPC companies, or for equipment manufacturers and module suppliers. A booth costs several lakh once build-out is included, while visiting costs only travel and time. Check the organiser’s current rate card.
For most smaller EPC founders, visiting as an attendee with a structured E2P Framework delivers better ROI than exhibiting. Exhibiting makes sense when lead generation at scale is the objective and your team size supports booth staffing of 3-4 people for the full event duration.
