In 50 words: Intersolar India 2026 returns to Mumbai's Bombay Exhibition Centre December 16–18 — the second-largest Indian solar trade show after REI Expo. Expected 18,000 attendees, 400+ exhibitors. Co-located with ees India (storage) and Power2Drive India (EV). Key 2026 threads: residential rooftop scaling, BESS-paired solar, ALMM cell certification, and India's role in supplying EU + Southeast Asian solar demand.
Intersolar India is the Mumbai-based counterpart to REI Expo — smaller in scale but with a more international flavor and tighter West India developer / EPC audience. This guide previews Intersolar India 2026: the event mechanics, the four threads to watch, and how it complements REI Expo for India solar industry attendees.
The event
Intersolar India 2026 runs December 16–18, 2026 at Bombay Exhibition Centre (Goregaon, Mumbai). Co-located with ees India (battery storage) and Power2Drive India (e-mobility) under The Smarter E India umbrella.
- 18,000+ attendees expected
- 400+ exhibitors across three co-located shows
- Stronger Maharashtra + Gujarat + Karnataka developer presence than REI
- Conference tracks: utility-scale solar, residential rooftop, BESS, manufacturing, policy
- Pre-show forums December 15
Four threads to watch
1. West India utility-scale solar pipeline
Maharashtra, Gujarat, Karnataka, and Rajasthan host the largest pipeline of new utility-scale solar projects (~25 GW combined under development in 2026). Intersolar India 2026's location in Mumbai makes it the natural venue for SECI/state utility tender discussions, EPC selection, and developer-financier dealmaking. For India context, see India solar 2030 280GW trajectory and India BESS coupled tenders 2026.
2. BESS-paired solar (FDRE tenders)
India's First Dispatchable Renewable Energy (FDRE) and Round-the-Clock (RTC) tender frameworks make solar + BESS pairing structurally important. Intersolar India 2026 will feature dedicated BESS-paired solar sessions, especially for the C&I market. See India BESS coupled tenders 2026 and BESS ancillary services India 2026.
3. ALMM cell-side certification
The transition from module-only ALMM List-I/III to cell-side ALMM List-IV (in active rule-making in 2026) is the structural manufacturing story for India. Intersolar India 2026 will host the first major industry deep-dives on cell PLI manufacturer readiness, line capability validation, and ALMM cell-certification timing. For background, see ALMM List-III 2026 update and India cell PLI List-IV 2026.
4. India as export hub for EU + SE Asia
Indian module manufacturers (Waaree, Adani Solar, Vikram Solar, Premier Energies, Goldi) are increasingly looking outside India for growth — EU under non-Chinese sourcing pressure, Southeast Asia under regional infrastructure demand, US under domestic-content premium economics. Intersolar India 2026 will host international buyer-seller matching sessions and EU CBAM compliance workshops. See India solar manufacturing 100GW 2026.
How Intersolar India differs from REI Expo
| Dimension | REI Expo (Greater Noida, October) | Intersolar India (Mumbai, December) | |---|---|---| | Scale | 35,000+ attendees | ~18,000 attendees | | Geography | North + East India focus | West + South India focus | | Audience | Policy-heavy (MNRE/SECI proximity) | Developer/EPC-heavy (West India hub) | | International presence | Moderate | Stronger (Intersolar global network) | | Co-located shows | 5 (REI ecosystem) | 3 (Smarter E ecosystem) | | Best for | Policy + manufacturer engagement | Project + finance + international |
Many serious India solar industry players attend both shows. The two-month gap (October REI → December Intersolar India) allows post-REI deal closure to be showcased in Mumbai.
Practical notes for attendees
- Location: Bombay Exhibition Centre, Goregaon East (~5 km from Mumbai domestic airport)
- Hotels: book early; December is peak Mumbai tourism season
- Registration: free for industry professionals with valid registration; on-site adds processing time
- Networking: opening reception December 15 evening is the biggest single dealmaking forum
