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.
UK tries to break gas link with voluntary long-term fixed price contracts for all renewables
UK solar plants without fixed-price contracts will be offered voluntary long-term fixed-price agreements under a new “Wholesale Contracts for Difference” regime from 2026. The policy seeks to reduce exposure to volatile wholesale prices driven by gas.
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%.
Control, not capacity, could be the next driver of US residential storage investment
Investors are shifting focus from deployment growth to platforms that can orchestrate and monetize battery fleets.
Insurance premiums trending down despite severe weather threat for solar
Insurance premiums for renewable energy projects in Australia are expected to decrease this year despite natural catastrophe and extreme weather exposures remaining a major concern, particularly for large-scale solar asset owners and investors.
Permitting headwinds, geopolitics drive North American solar PPA prices higher in Q1
A report from LevelTen Energy finds North American solar PPA prices rose 4.6% in the first quarter of 2026 as developers navigate a complex regulatory and geopolitical environment.
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.
California powers its massive water pumps with 105 MW solar project
California is putting the sun to work on the heavy lift that keeps California hydrated.
