Solar Fabrik has introduced a 400 W red-brown glass-glass PV module designed to meet strict aesthetic requirements for historic and protected buildings, offering a 20.02% efficiency and compatibility with traditional tiled rooftops.

Latest analysis from Ember finds major grid bottlenecks in transmission and distribution networks across Europe, threatening the viability of both future utility-scale and smaller-scale residential solar in the most impacted countries.

Cornell University researchers demonstrated that tracking solar panels in agrivoltaic systems can protect crops from wind damage while allowing airflow, outperforming traditional single-row tree windbreaks. They also proposed a new lowered-first-row panel design that improves wind protection, achieving up to 86% reduction in shelter-zone wind speeds under extreme conditions.

Distributed solar accounted for 15% of all new US power capacity in 2025, as residential and community projects reached record installation levels.

Swiss analytics firm Pexapark says the latest developments in the Middle East are having a visible effect on long-term power purchase agreement (PPA) valuation in Europe, as the market begins to reprice the coming years.

The European Union Agency for Cooperation of Energy Regulators (ACER) is running a public consultation on the evolution of the bloc’s power purchase agreement (PPA) market to identify existing initiatives and challenges.

Research from Germany analyzed sentiment in online news coverage to explore how heat pumps are portrayed in German public discourse. It found that while public perception is generally positive, it is neither uniform nor stable, and dipped significantly during debates around Germany’s heating law in 2023.

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.

Available in 80 W and 108 W versions using high-efficiency SunPower Maxeon cells, the kit offers wind resistance up to 25 m/s and easy installation on unused boat surfaces, according to the manufacturer.

SolarEdge has outlined a transition pathway to integrated 800 V (DC) infrastructure for data centers, arguing that legacy alternating current (AC) systems introduce inefficiencies that could constrain the growth of AI workloads. It says rising compute demand and next-gen NVIDIA GPUs are increasing urgency, while data centers lose an estimated 10% to 30% of input power through multiple conversion stages.

Researchers in India demonstrated that ion beam implantation enables precise boron doping in silicon solar cells, reducing defects and improving charge transport. The proposed approach could support more efficient and reproducible p–n junctions, offering a pathway to higher-performance silicon photovoltaics.

UNSW researchers developed a chemically selective, nitrate-based, single-sided accelerated ageing method for TOPCon solar cells that replicates the mildly acidic environment inside EVA-encapsulated modules. The proposed approach enables rapid, physically meaningful screening of front-side metallisation stability, reliably predicting module-level degradation and reducing development time and costs, according to its creators.

Researchers in Brazil tested second-life polycrystalline PV modules for two years and found they retained 87–88% of their original power, with minimal degradation and stable performance. Despite strong sustainability and circular economy benefits, economic incentives remain limited due to the declining cost and short warranties of new state-of-the-art silicon PV modules.

JinkoSolar has formally terminated its 4 GW Hai Ha solar cell project in Vietnam, citing US antidumping duties that undermined its export economics. The company will maintain other Vietnamese operations while shifting focus to localized supply chains and Asia-Pacific and Middle East markets.

Premier Energies Ltd has commenced trial production at its 5.6 GW solar module manufacturing facility in Seetharampur, Telangana. The new facility produces G12R TOPCon modules with zero busbar (0BB) architecture.

The International Finance Corporation is providing an A Loan to Malaysian polysilicon producer OCI TerraSus that will partly finance the development of a semiconductor-grade polysilicon production facility in Sarawak, Borneo.

As Europe prepares to roll out 200 GWh of battery storage over the next five years, discussion at the Battery Business & Development Forum 2026 turns to how financing models are rapidly shifting. Bankers, developers and stakeholders shared key pain points with the audience, as well as practical advice.

Azerbaijan President Ilham Aliyev has inaugurated a major battery energy storage system (BESS) project as part of a 500 MWh rollout to strengthen grid stability and support renewable energy integration.

Investors at the Battery Business & Development Forum (BBDF) 2026 signaled continued confidence in the energy storage market, while warning that regulatory uncertainty, particularly around grid fees in Germany, could affect project economics and investment decisions.

Italy’s energy regulator ARERA has approved a proposal from the Ministry of the Environment and Energy Security to target 16 GWh of storage capacity in the 2029 MACSE auction, while urging caution on final volumes to reflect existing pipeline capacity.

Lithuania added approximately 600 MW of solar last year, taking total capacity to 3,040 MW. Technical permits have been issued for an additional 4 GW of solar but with grid congestion becoming a primary constraint, future deployments will be increasingly dependent on integration with storage technologies.
