A closer look at EcoFlow’s three-phase Ocean 2 storage solution
Ocean 2 brings a more versatile large-scale and expandable, modular home storage solution, capable of handling both small and large solar PV input.
How to operate PV-driven residential heat pumps under time-varying tariffs
Researchers in the United Kingdom developed a scheduling model for residential heat pumps that reduces electricity costs while maintaining thermal comfort under dynamic tariffs and uncertain rooftop PV generation. It optimizes when to use grid power, PV energy, and building thermal storage.
The world added 605 GW of new PV capacity in 2025, says IEA
Latest report from the International Energy Agency says last year’s 600 TWh increase in solar PV was the largest-ever electricity generation increase by any source in one year, outside of periods of post-crisis recovery.
Rongke Power debuts 2 MW/8 MWh vanadium flow battery storage system
The Chinese company says the new product targets long-duration storage, grid support, and GWh-scale deployment.
Fabricating perovskite solar cells with robotic boxes
An international research team has developed an AI-driven robotic platform that autonomously designs, fabricates, and optimizes perovskite solar cells, completing the full experimental workflow in a closed-loop system. Using the platform, the researchers fabricated and tested more than 50,000 devices, achieving efficiencies of up to 27%.
Tandem PV launches commercial perovskite-silicon manufacturing in California
Tandem PV has opened a 40 MW commercial demonstration factory in Fremont, California, marking a significant transition for perovskite-silicon technology from laboratory development to repeatable manufacturing at scale.
Jinko Power enters data center business with 1 GW project in China
Jinko Power signed a framework agreement with Zhongwei to develop a 1 GW data center in Ningxia, marking its entry into green computing under China’s “Eastern Data, Western Computing” initiative. The project, however, remains subject to approvals and funding scrutiny.
A closer look at CATL’s new sodium-ion battery
The battery manufacturing heavyweight presented its latest sodium-ion products at ESIE 2026 earlier this month, expanding its push into grid-scale storage, AI data centers, and long-life applications.
Could global warming improve heat pump efficiency in Alpine regions?
Researchers in Italy analyzed air-to-water heat pump performance in Alpine regions, focusing on how start-up and defrost cycles affect efficiency under current and future climate conditions. Their simulations show that while warmer temperatures slightly reduce defrosting losses and modestly improve efficiency, start-up cycling losses remain significant and continue to limit overall performance gains.
Solar rebound effect could raise Europe’s electricity demand 5% by 2050
Research from Germany’s FernUniversität Hagen finds the solar rebound effect, caused by households increasing their total electricity consumption after installing a solar system, is currently a blind stop in Europe’s energy system planning and abatement scenarios.
