Switzerland startup Evolium Technologies’ subscription-based business model offers residential battery owners a lifetime guarantee on second life batteries. The startup tests and remotely monitors each battery cell so it can alert customers when a cell is under-performing.

China-based solar manufacturer Longi is shifting from a multi-vendor system design to a unified solar-plus-storage architecture built around in-house technologies.

The “lab” session at Battery Business & Development Forum 2026 made transparent how different stakeholders evaluate and view energy storage projects between standalone and co-located options, and where views diverged.

France’s Association Environnement Juste has proposed a storage mandate for renewables projects exceeding 10 kWp in order to integrate flexibility at the source. The association argues European sodium-ion batteries could present an economically and environmentally viable solution, capable of stabilizing grids without depending on imported metals.

Bosa Energy in Hubei, China, has launched sodium-ions cells for stationary energy storage, with a volumetric energy density of 206 Wh/L

Global solar PV continues its rapid growth, reaching around 650 GW in 2025, with record solar irradiation extremes across regions such as East Asia, India, and Latin America. With current production capacity and emerging technologies like perovskite-silicon tandem modules, PV is poised to surpass all other electricity generation technologies combined by the end of the decade.

Spain’s grid operator Red Eléctrica and regulator CNMC have launched real-time voltage control services, allowing renewable energy installations to provide dynamic grid support under a new regulatory framework.

Researchers found that widely deployed smart meters pose a “massive” cybersecurity risk, potentially enabling data manipulation, energy theft, and service disruption. They propose a new detection method using state estimation and statistical boundaries to more accurately identify cyberattacks, outperforming traditional techniques despite higher computational demands.

Ghana’s Minister for Energy and Green Transition says the country will advertise competitive bidding processes to deploy 200 MW of battery storage across the country. Ghana’s current installed battery capacity stands at 10 MWh.

In an interview with pv magazine, cybersecurity expert Mohammad Al Faruque explains how seemingly simple sensors in PV systems and other energy systems are surprisingly vulnerable to magnetic, electrical, and acoustic perturbations, which can remotely influence control systems without physical access. Protecting these sensors requires both strict physical security and the development of hardened, interference-resistant technology to safeguard critical infrastructure.
