Renewable Energy India Expo (REI Expo) 2026 runs October 22–24 at India Expo Mart in Greater Noida, Delhi NCR, covering solar, bio-energy, energy storage, green hydrogen and e-mobility. The organiser describes it as one of Asia's largest clean-energy exhibitions, with 1,000+ brands across 14 halls and more than 55,000 visitors (organiser's own figures).
What's on show
- Solar: modules, inverters, mounting and rooftop systems.
- Energy storage: batteries and grid-scale storage.
- Green hydrogen and bio-energy.
- E-mobility: charging infrastructure and EV components.
If you're attending, check visitor registration on the official site. Registration deadlines can fall before the show.
Why I'm writing about a renewable energy expo
Because I build websites for clean-energy businesses. One example is Saurally, a solar e-commerce store with 40+ products, filtering, comparison and multi-gateway payments. I see the same gap again and again: excellent products, and websites that don't do them justice.
What a solar or clean-energy business website needs
- Product pages for engineers and homeowners alike: specifications and datasheets for installers, and plain-language benefits and savings for homeowners.
- A quote or site-survey flow, not just a contact form: roof size, location, monthly bill and connection type.
- Subsidy and finance information, stated clearly and kept up to date.
- Local SEO for "solar installer in [city]" searches, with service-area pages that are genuinely useful.
- Trust: certifications, completed installations with photos, and reviews.
After the expo
The leads you collect at a trade show go cold quickly. A website with a strong quote flow and fast follow-up turns expo conversations into orders.
At NextGen Fusion, our web development company in Lucknow, we build websites and online stores for solar and clean-energy brands.
