Experience Smarter Solar and Battery Storage at REI 2026 with Ornate Solar!

India is adding solar faster than ever. But there’s a catch: solar power peaks at noon, while demand peaks in the evening. Without battery energy storage system, much of that clean energy can’t be used when commercial, industrial and utility-scale operations need it most.

The answer is smarter solar with battery storage system, and that’s exactly what we’re bringing to REI 2026!

From 22 to 24 October 2026 at the India Expo Mart, Greater Noida, Ornate Solar will showcase UnityESS, our Battery Energy Storage System built for everything from commercial, industrial to utility-scale solar plants.

For smarter solar, you’ll also see India’s first BIS-approved indigenous solar inverter and InRoof, a factory roof made entirely of solar panels. Here’s what each one does, why it matters, and what you can see at Hall 15, Booth C112.

India is now one of the fastest-growing solar markets in the world, and 2026 has been a record year.

• 168 GW+ of installed solar capacity by the end of August 2026 (SolarQuarter, citing MNRE)
• Nearly 34.45 GW of new solar added in just the first eight months of the year
• About 299 GW of total renewable energy capacity as of September 2026 (JMK Research)
• About 33.4 GW of rooftop solar, driven by homes and businesses under schemes like PM Surya Ghar: Muft Bijli Yojana

But more solar also brings new questions. What happens to the power after sunset? Can the inverters and equipment we use be made in India? How do factories add solar without losing roof space?

These are exactly the questions our products at REI 2026 are built to answer.

This year, battery storage takes centre stage at our booth, supported by two smarter solar solutions from Ornate: an inverter made in India and a roof that makes its own power.

A Battery Energy Storage System (BESS) bridges the gap between when solar power is generated and when it is needed. It stores energy when it is available and releases it when you need it.

UnityESS is our BESS brand, built as a joint venture between Ornate Solar and Inverted Energy. It comes in three systems, so there is a fit for every scale:

• Backup power when the grid fails, with switchover in under 20 milliseconds on Unity Aura
• Lower power bills by storing low-cost solar and using it during expensive peak hours
• Less diesel, by replacing DG sets as your backup source
• More value from your solar, by storing energy that would otherwise go to waste

UnityESS is backed by real experience: Ornate Solar has deployed over 1 GW across India in the last decade, and Inverted Energy has built more than 1 million batteries.

Every UnityESS system uses LFP (Lithium Iron Phosphate) cells, comes with built-in fire protection, and is managed by our own Unity EMS software for monitoring and smart charging. Battery packs carry a 5-year standard warranty, extendable to 10 years.

New to battery storage? Start with our guide: How Does a Battery Energy Storage System (BESS) Work?

Building one from scratch took three years of dedicated engineering, research and persistence. Our in-house R&D team worked on every layer of the technology, from circuit architecture and PCB design to embedded software, protection systems and thermal management. Each prototype brought new challenges, requiring repeated experiments, rigorous testing and continuous refinement. The inverter was also evaluated at TERI Laboratory to validate its performance and reliability.

That hard work led to a defining milestone: India’s First Indigenous solar inverter successfully cleared BIS testing on its very first attempt. More than a product achievement, it reflects our commitment to developing solar technology through Indian engineering and in-house innovation

• BIS approved, and it cleared BIS testing on its very first attempt
• Passed 557 BIS/IEC tests covering safety, anti-islanding, grid connection and efficiency
• Built-in MPPT to get the most energy out of your panels

At REI, you can see the inverter up close and meet the engineers who built it. Read the full story in our blog: From Vision to Reality: India’s First Indigenous Solar Inverter.

Ornate InRoof replaces the metal sheet roof of an industrial building with solar panels. The panels themselves become the roof, so you get a shelter and a power plant in one.

• Fits up to 26% more panels than a regular rooftop setup in the same space
• Natural airflow under the panels improves generation by up to 10%
• Leak-proof design, with no separate metal roof needed
• Clean look with no protruding hardware, suitable for new buildings and roof replacements

InRoof is ideal for factories, warehouses and sheds that want to go solar without giving up roof space.

Along with our own products, we will showcase equipment from the global and Indian brands we partner with. This makes our booth a one-stop destination to see a complete solar system, from panels to inverters to battery storage.

You will also find BIPV solutions, solar carports, solar trackers and SolarEdge inverters at the booth.

Whether you are planning, building or buying solar, our booth has something for you:

• Factory and warehouse owners looking to cut power bills, reduce diesel use or replace an old roof
• EPC companies and installers sourcing reliable panels, inverters and storage
• Project developers working on utility-scale solar and hybrid projects
• Architects and builders exploring solar roofs and building-integrated solar
• Students and first-time visitors who want to understand how solar and battery storage work

Our team will be at the booth all three days to explain each product, answer technical questions and discuss your project.
