A study of 20 solar parks in southern France found that soil biodiversity and respiration drop significantly under panels, especially in mown areas, while plant traits like height and leaf area can increase under grazing. The researchers highlighted that climate, management type, and solar shading all shape soil and plant responses.

Australian solar and thermal energy storage company RayGen says it has achieved a major international milestone with the commissioning of a 1 MW integrated solar electricity and hydro energy storage plant in Brazil.

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.

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.

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.

Bhutan is seeking expressions of interest from private sector players interested in developing solar projects under a build-own-operate basis. The first deadline to register interest is April 30. 

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.

The U.S. Department of Energy is deploying a research framework across four national laboratories to harden the domestic power grid against digital vulnerabilities as solar deployment accelerates.

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.
