Brazil’s plan for a battery supply chain

Battery manufacturing in Brazil is being spurred by local content requirements for country’s December 2026 energy storage auction, as well as the financing terms from Brazilian development bank BNDES that are favorable to locally made products. Domestic and foreign suppliers are already announcing investments in battery manufacturing facilities.

Sweden could face 150,000 metric tons of end-of-life panels annually

Sweden decommissioned just 17 metric tons (MT) of solar panels in 2021, but a new industry roadmap warns that figure could reach 150,000 MT per year by around 2060, and says current recycling and reuse systems are not yet equipped to handle it.

AC-Coupled vs. DC-Coupled

Growing applications for battery storage mean the optimal system design may not be the most obvious. Jakir Hossain and Mujtaba Abdelwahab of Storlytics Energy Storage present a simulation-based comparison of AC vs. DC coupling showing how realistic dispatch modeling rather than generic assumptions fundamentally changes BESS sizing, levelized cost of electricity (LCOE) outcomes and architecture selection.

New materials in the frame

Solar cells, encapsulants, glass, backsheets, and virtually every PV module component have seen rapid changes and improvements over the past 10 years. During that time, module frames have seen relatively little innovation and remain a simple piece of formed aluminum. However, quality concerns, supply chain diversification, domestic content rules, and emissions reduction requirements have frame manufacturers eyeing alternative materials. And while aluminum isn’t going away, suppliers of steel and glass composite frames argue these materials come with various advantages.

AZO-based HJT solar cells more vulnerable to damp-heat-induced degradation, study finds

German researchers have found that aluminum-doped zinc oxide-based silicon heterojunction cells are more vulnerable to damp-heat-induced degradation than their indium tin oxide-based counterparts. To address this issue, they introduced a magnesium fluoride capping layer that significantly improved damp-heat stability by slowing moisture penetration and corrosion.

New temperature model improves floating PV performance predictions

Researchers in Malaysia have developed a simplified operating cell temperature model for floating photovoltaic (FPV) systems that incorporates water temperature while remaining compatible with existing nominal operating cell temperature (NOCT) models. The FPV-NOCT model outperformed the standard NOCT approach in validation datasets from Brazil and California, achieving up to 92.3% prediction accuracy.
