Finland’s large-scale solar capacity more than doubled in 2025, buoyed by the commissioning of the country’s first solar projects larger than 50 MW. Another record year for ground-mounted solar is expected this year but a forthcoming Land Use Act risks threatening future projects.

The WTO ruled that U.S. clean energy tax credits under the Inflation Reduction Act violate international trade rules by giving domestic products preferential treatment over Chinese goods. The decision specifically targets the ITC and PTC Domestic Content Bonus Credits.

A new bifacial PV optimization model for 18 Saudi Arabian cities identifies optimal tilt and azimuth, showing rear-side irradiance can boost annual energy yield by 8–12 % and shifts tilt 3°–11° higher than monofacial modules. The framework validates previous studies, highlights high- and low-performing locations, and serves as an early-stage planning tool before detailed project simulations.

Researchers at NREL found that UV exposure can cause significant, partly non-recoverable degradation in TOPCon solar cells, with strong cell-to-cell and intra-cell variability linked to passivation and processing inconsistencies. While some UV-related losses recover quickly under light and are unlikely to affect field performance, the findings highlight gaps in current qualification tests and the need for improved UV aging standards.

Spain installed 1.14 GW of solar capacity for self-consumption in 2025, lifting cumulative capacity to 9.3 GW, as residential and commercial installations declined while industrial and off-grid segments showed greater resilience, according to data from the Spanish Photovoltaic Union.

54% of respondents cited “energy availability and redundancy” as the single greatest obstacle to successful data center development between now and 2030.

Brazil curtailed about one-fifth of its solar and wind generation in 2025, wasting an estimated BRL 6.5 billion ($1.23 billion), as grid constraints and demand mismatches pushed the power system close to operational safety limits on 16 days, according to a report from Volt Robotics.

French researchers have developed a high-resolution computational framework to model microclimate effects of large floating solar PV systems, enabling accurate predictions of heat transfer, ambient temperatures, and water evaporation based on panel configuration and wind conditions. The model can inform thermal performance, environmental impacts, and optimize designs for utility-scale floating PV, as well as ground-mounted and agrivoltaic installations.

After hitting an all-time high of $121.65/oz on Jan. 29, silver prices have tumbled to $79.44/oz, with analysts warning of a potential drop toward $50/oz.

Renewables and storage could reliably power data centers, but success requires active grids, coordinated planning, and the right mix of technologies. Hitachi Energy CTO, Gerhard Salge, tells pv magazine that holistic approaches ensure technical feasibility, economic viability, and energy system resilience.
