Solar storage

Pricing trends in the new year reveal a split between premium, performance, and low-voltage residential systems, while commercial pricing stays largely unchanged compared to December, as per sun.store data.

The US state of Texas is seeing rapid growth in a new battery-only programme, connecting thousands of homes to a networked grid resource and adding hundreds of megawatt-hours of flexible capacity.

For the twelfth consecutive year, the EU achieved a record level of battery storage installations, driven primarily by utility-scale projects. Residential installations declined.

The new C Series battery cabinet delivers 125 kilowatts of power and 261 kilowatt-hours of storage, all within a compact footprint of less than 1.5 square metres.

PV Guided Tours: Industry and commercial enterprises can reduce electricity costs in various ways using storage systems – but security is key. Luis Haya, Solution Manager Chint Power Systems, explains which features are needed to ensure security is safeguarded.

Energy costs matter. They shape competitiveness, whether a company is trading internationally or serving the local market. And with fossil and nuclear prices heading in only one direction, renewable energy from sun and wind is looking less like an alternative and more like the smart money.

PV Guided Tours: Atmoce presents two new innovative products – a micro inverter and a low-voltage battery. The M-ELV battery operates at less than 30 volts, increasing safety for installers and simplifying day-to-day work. Intelligent energy management system connects both components. The low-voltage technology is designed to benefit private households as well as commercial users.

Backed by a €230 million investment, Sungrow’s first European factory in Wałbrzych will start operations within 12 months, manufacturing battery storage systems and PV inverters for Europe.

Large-scale storage systems are gaining ground across Europe, driven by growing demand for grid stabilisation and peak load shifting. Italy, Great Britain and Germany are leading the charge. Download our latest free e-paper now.

Most C&I storage systems today do more than one job. They maximise use of rooftop solar, shave peak loads, take advantage of low-cost grid power when available, smooth frequency fluctuations and keep the lights on during grid interruptions. In short, they deliver real, tangible value. Don’t miss our upcoming investor newsletter on 11 February 2026 – sign up now.

CEO Talk: Demand for large storage systems is surging across Europe, but delivering them involves major challenges – from permitting and financing to construction and operation. Michael Hierholzer of Rolls-Royce explains why experienced and reliable partners are key.

 Croatian Solar Flex 2026 brings together investors to examine battery storage potential and the role of demand-side flexibility in lowering energy costs.

Supervised by fire engineering consultancy Hiller and certified by TÜV Rheinland, the test demonstrated the system’s enclosure integrity, fire isolation, use of resistant materials, and the reliability of critical systems under extreme fire conditions.

Metlen and Tsakos Group will jointly invest in one of Greece’s largest hybrid plants, combining large-scale solar generation with 375 MWh of battery storage, scheduled for completion in early 2028.

PV Guided Tours: Huawei FusionSolar is unveiling its new Luna2000 utility-scale battery storage system with a capacity of five MWh. The current 4.5 MWh systems have already received the Prime safety certificate from TÜV Rheinland.

Awarded under Italy’s Capacity Market auction for 2027, the 250 MW / 1,000 MWh system in Rondissone will feature Trina’s latest Elementa 2 Pro batteries and a 20-year LTSA.

The global solar tech supplier showed off its enhanced PowerTitan 3.0 and a single-platform design for its DC-coupled solution at the PV & EES Summit in Madrid.

PV Guided Tours: SAX Power offers an AC storage system that operates without a battery inverter. It is also a multi-talent – suitable for both new solar systems and retrofits. Is this storage system really as simple as the provider promises? Watch the video to find out.

PV Guided Tours: Fenecon presents the Industrial XL with 1.5 MW and four MWh in a new container format for large-scale projects, alongside a flexible power pack for SMEs and the updated Commercial 92 featuring an innovative split-tower design.

PV Guided Tours: The integrated Power Store sytem from Denios combines a C&I battery unit with a safety container, designed to protect against thermal runaway while enabling tailored design and fast amortisation. Watch the video to learn more.

The utility-scale platform offers integrated DC/AC optimisation, robust diagnostics and a compact design, cutting footprint and streamlining installation even for large storage projects.

PV Guided Tours: The system supplies three-phase backup power and utilises an intelligent EMS. The focus is clearly on safety and efficiency – including for the new, hybrid-cooled Luna2000-215kWh battery storage system for C&I. It has been awarded the highest safety certificate by TÜV Rheinland.

Podcast: The Energy Center from ESS Inc. in Oregon is an iron flow storage system offering 1.16 MWh of capacity and 174 kW of maximum charge power. Housed in a single container, the modular unit suits a range of commercial and grid applications. Alan Greenshields, Director EMEA at ESS, discusses long-duration storage and the role of redox flow technology using sustainable materials like iron, salt and water.

PV Guided Tours: Intelligent systems are replacing standalone components and AI now manages storage systems, wall boxes and energy flows to make the most of solar power. It’s not science fiction, it’s already here. Still sceptical? Prepare to be surprised!

The storage project forms a key element of Trelleborgs Hamn’s strategy to boost self-sufficiency and comply with forthcoming EU requirements for shore-side electricity supply for larger vessels.
