Spain hits first weekday of 100% renewable power on national grid
Spain’s grid ran entirely on renewable energy for the first time on April 16, with wind, solar, and hydro meeting all peninsular electricity demand during a weekday. Five days later, solar set a new record, generating 20,120 MW of instantaneous power – covering 78.6% of demand and 61.5% of the grid mix.
France deploys 1.4 GW of solar in Q1
France installed 1.4 GW of solar in the first quarter of 2025, bringing its cumulative PV capacity to 23.5 GW by the end of March.
Rhoss launches reversible heat pumps
Conceived for industrial applications, the novel heat pumps can reportedly deliver hot water at 65 C from -10 C up to 35 C of external air, and hot water at 55 C down to -20 C of external air. Their coefficient of performance reaches up to 3.60.
Net metering policies see significant revision in states across the U.S.
The recent 50 States of Solar report from NC Clean Energy Technology Center identifies three trends in state policy activities and the top five distributed solar actions in Q1 2025.
Ireland hit new daily peak with over 750 MW of grid-scale solar in March
March 2025 was a record month for solar generation on Ireland’s electricity grid, according to provisional real-time data from the country’s transmission systems operator EirGrid. Solar accounted for 2.8% of the country’s total electricity generation during March.
Teledyne Flir presents new PV inspection products
Teledyne Flir, a US-based sensing solutions company, has launched new PV inspection tools – including a clamp meter, irradiance meter, and I-V curve tracer – alongside two product kits targeting solar installers, utilities, and PV manufacturers.
PV-driven heating, cooling system for supermarkets
Scientists in China have developed a novel PV-powered cooling and heating system that combines a water-cooled gas cooler and an air-cooled gas cooler. The system went through a series of simulations and showed it can potentially achieve a coefficient of performance of up to 7.34.
New WMO analysis underscores 2024’s solar anomalies
In a new weekly update for pv magazine, Solcast, a DNV company, writes that while findings from the The European State of the Climate 2024 report align with its own solar analysis covering last year, differences in anomaly magnitude between the two datasets stem from the climatology periods used.
Swiss researchers developing control algorithm for grid-forming inverters
Researchers at ETH Zurich have patented a grid-forming inverter algorithm that stabilizes frequency while protecting devices from damage by independently controlling frequency, voltage, and current.
Testing floating PV at different heights
Scientists have tested the performance of floating PV panels at a height of 800 mm and 250 mm above their floating structures. Their thermal and electrical performance was compared to that of a reference land-based system and the highest panel was found to show the greatest cooling effect.
