Powerchina has finished the 200 MW Guayepo III solar farm in northern Colombia, connecting it to the grid six days ahead of schedule for Italian utility Enel.

In its latest monthly for pv magazine, the International Solar Energy Society (ISES) explains how pumped-hydro energy storage combined with PV power generation could provide 24/7 power to data centres

The energy regulator of the Philippines has approved an increase in the feed-in tariff allowance (FIT-All) to PHP 0.2073 ($0.004)/kWh from PHP 0.1189, with the new rate set to take effect next month.

pv magazine spoke with energy and environmental law expert Anatole Boute about the past and future role of the World Trade Organization (WTO) in regulating trade disputes related to clean energy technologies amid current geopolitical tensions. He noted that despite recent protectionist efforts to revive the solar manufacturing industry, the European Union still strives to remain compliant with WTO rules.

Scientists in Japan have used a deep reinforcement learning–based AI model to calculate discrepancies between the planned and actual electricity supply volumes in PV-battery systems operating in markets where grid imbalances are penalized. Through a series of simulations, they found that the proposed methodology can reduce imbalance penalties by approximately 47%.

Romania plans to amend its energy law to require the National Cybersecurity Directorate (DNSC) to define technical standards for PV and cogeneration systems up to 1 MW, aimed at preventing data breaches and safeguarding grid operations.

An international research team has developed a tracker-based rooftop PV system that can be installed on both new and existing stadiums. The proposed design reportedly allows for easier deployment and delivers higher power output compared to conventional stadium PV covers.

Mexico’s Secretaría de Energía (Sener) plans to add 6.4 GW to 9.5 GW of renewable capacity while keeping state-owned CFE’s share above 54%, integrating storage and efficiency measures to stabilize the grid.

Researchers in Japan have adopted a new calcium-doping strategy to improve the stability and electrochemical properties of NFM, a cathode material used in sodium-ion batteries. The new technique enhances crystallinity and increases the interlayer spacing in NFM, resulting in higher performance compared to NFM treated with conventional processes.

Spain’s new agricultural decree allows land hosting solar arrays to qualify for Common Agricultural Policy payments if farming remains the primary activity.
