New electrode design increases battery energy density by up to 15%
Fraunhofer ISE and its partners have developed thicker electrodes that could increase battery cell energy density by 10% to 15% without adding weight. The PFAS-free, solvent-free concept has been demonstrated in lithium-ion, sodium-ion, and zinc-ion cells and is designed for cost-effective mass production.

Sungrow turns to Samsung SDI battery cells to sustain its energy storage business
ungrow plans to procure Samsung SDI battery cells for its energy storage systems, primarily to support continued deliveries to the U.S. market amid tightening restrictions on China-linked supply chains. The potential three-year, multi-GWh LFP deal could leverage Samsung SDI’s expanding U.S. production footprint, although procurement volumes, manufacturing locations and commercial terms remain undisclosed.

From more than 50 GW to under 10 GW: Ukraine doesn’t need its old energy system back
Six air-raid alerts on the first day, backup generators on almost every street corner, and discussions about the rapid reconstruction of severely damaged energy infrastructure: my trip to Kyiv and Lviv showed me why decentralized solar and energy storage are far more than climate technologies for Ukraine. They are part of the country’s security architecture. They also underscore why German solar companies should be engaging with Ukraine today.

Italian solar redrew the day, but gas still sets the price
Solar growth softened Italy’s midday power squeeze in summer 2026, but higher heat-driven demand and weaker hydro and wind left gas to cover most of the 7.9 TWh supply gap. The result was a sharper evening exposure: gas generation surged, prices rose most after sunset, and solar-heavy southern zones increasingly faced midday oversupply and weaker capture rates.

Reliability risks emerge across BIPV, floating PV and agrivoltaics
A new IEA PVPS Task 13 report identifies distinct reliability risks across BIPV, floating PV and agrivoltaics, from heat and partial shading to wave loads, ammonia exposure and soiling. It argues that existing PV qualification standards do not fully capture these application-specific stresses, requiring adapted testing, design practices and performance metrics.

Hitachi launches CO2 heat pump water heaters with solar-friendly tariff controls
Hitachi has introduced its Y-series EcoCute CO2 heat pump water heaters in Japan, with 370-liter and 460-liter models set to launch from November 2026.
The upgraded range adds expanded support for daytime electricity tariffs and PV-linked energy management, alongside a five-year manufacturer warranty.
El Niño transition and a subtropical shift reshape Asia’s summer solar resource
In a new weekly update for pv magazine, Solcast, a DNV company, reports that Summer 2026 brought sharply contrasting solar conditions across Asia, as a northward-shifted Western Pacific Subtropical High reduced irradiance in Northeast China while boosting it across central China. Farther south, developing El Niño conditions and a positive Indian Ocean Dipole suppressed cloud across eastern Indonesia and Papua New Guinea, driving irradiance up to 25% above average.
India’s solar module overcapacity pushes factory utilization to 35–40%
India’s solar module manufacturing capacity has surged to 233 GW, outpacing domestic demand and pushing factory utilization down to 35–40%. A new IEEFA-JMK Research report warns that continued capacity additions could intensify pressure on margins and increase the risk of stranded assets.

Fighting coastal corrosion
Salt in the air can wreak havoc with projects that lack the necessary corrosion resistance, proving costly for asset owners or the engineering, procurement and construction (EPC) companies that built them. Alexander Gebert, sales director at Tobsteel, argues that quality stainless steel fasteners can save costs for solar investors and engineering, procurement and construction (EPC) contractors in the long run.

Heterojunction’s long road to the US solar factory
For a cell technology that has spent much of the past three decades on the verge of a breakthrough, heterojunction (HJT) is enjoying another moment in the spotlight. This time, however, the setting is somewhat unexpected – rather than the established manufacturing centers of China and Southeast Asia, some of the most significant new commitments to HJT are emerging in the United States, Finlay Colville reports.

Ireland’s leap of faith to power data centers
Under Ireland’s Large Energy User Action Plan (LEAP), 10 MW-plus data centers must provide at least 80% of their energy demand through new onsite renewable energy generation and storage. But whether data centers can meaningfully contribute to Ireland’s decarbonization depends on the success of its grid buildout, reports Blathnaid O’Dea.

France’s installed PV capacity hits 34 GW
France connected 3 GW of new solar capacity in the first half of 2026, slightly above the 2.9 GW deployed in the same period of 2025. Large-scale installations above 500 kW accounted for 28% of newly connected capacity, despite representing just 0.3% of new connections. Systems below 9 kW dominated installation numbers, accounting for 78% of new connections but only 8% of added capacity.
