Every solar project is really three machines working as one: something that makes the power, something that shapes it for the grid, and something that keeps it for later. At REI Expo 2026 in Greater Noida, Solarworld Energy Solutions launched all three at once — a new home battery range, a utility-scale power conversion system, and a high-output solar module — and in doing so marked its move from a solar builder into a company that can serve a customer from rooftop to utility scale.
Solarworld Energy Solutions, headquartered in Noida and founded in 2013, has spent more than a decade building solar projects across India — engineering, procurement and construction for public-sector and commercial customers, solar parks, and rooftop and ground-mounted installations. The company says its project portfolio exceeds 1.5 GW, and it manufactures solar modules and battery energy storage systems at its facilities in Roorkee, Uttarakhand. The three launches at REI Expo, at booth B569 in Hall 11, are the clearest statement yet of where that experience is heading: generation, conversion and storage, offered together.
The first launch is for the home. Solarworld’s new lithium iron phosphate (LFP) home energy storage batteries come in three sizes — the SW12100 at 1.28 kWh, the SW24100 at 2.56 kWh, and the SW51100 at 5.12 kWh — each built around 100 Ah LFP cells and designed for home inverters, UPS systems and solar-plus-storage installations. A built-in battery management system protects against over-voltage, under-voltage, over-current, short circuits and temperature risks, and the company says the range complies with IS 16270, IEC 62619 or UL 1973, and UN 38.3, with a five-year product warranty. For a household with rooftop solar, that is the difference between using sunshine only while it shines and keeping it for the evening — the very idea behind the PM Surya Ghar: Muft Bijli Yojana, which targets one crore households.
The second launch is for the other end of the scale. The SWPCS2500, developed under joint branding with Belectriq, is a central power conversion system for utility-scale solar and storage projects, rated at 2,500 kVA with a maximum AC power of 2,750 kVA and a maximum DC voltage of 1,500 V. The company says it reaches up to 99% efficiency using a three-level topology, works in both grid-connected and off-grid modes, and communicates over RS485, CAN and Ethernet, with air and liquid cooling and an IP55 control cabin. It is the quiet, hard-working heart of a large project — the box that turns everything a solar farm generates into power the grid can actually use.
The third launch is the module itself. The AQUILA bifacial G12 series, rated from 650 Wp to 715 Wp, uses N-Type TOPCon bifacial cells and is made in India by Solarworld’s subsidiary, ZNShine Solarworld Private Limited. The company says the modules reach up to 23.02% efficiency, use a 16-busbar cell design with a glass-to-glass bifacial build, are IEC certified, BIS approved and ALMM listed, and carry a 12-year product warranty with a 25-year performance warranty. A low temperature coefficient of -0.29% per degree Celsius, an IP68 junction box and PID-resistant construction complete a module built to keep producing through Indian summers and long project lives.
Behind the three products sits a manufacturing story that is still growing. The company says it runs a 1.552 GW solar module facility in Roorkee, a 3.6 GW battery energy storage manufacturing facility, and a 5 GW junction-box line, and it is setting up a 2.4 GW solar cell plant in Narmadapuram, Madhya Pradesh, in partnership with Rays Power Infra — the backward-integration step that turns a module maker into a company that controls more of its own supply chain. For larger customers, Solarworld already offers liquid-cooled storage systems, including a 125 kW / 261.24 kWh system for commercial and industrial users and a 5,015 kWh container for utility and industrial use.

As Solarworld’s managing director Kartik Teltia put it at the launch: “India’s solar sector is moving from installing capacity to building complete, locally supported energy systems. Developers and customers today look for integrated solutions across generation, conversion and storage, and they want the confidence of dealing with fewer, more capable suppliers.” That is exactly what these three launches deliver — a panel that makes more power, a converter that handles it at scale, and a battery that keeps it for when it matters. From a rooftop in a housing colony to a utility project on the grid, Solarworld now has an answer at every point where sunshine becomes electricity.
