German solar PPA deals drop 87% as developers turn to battery hybrids
With German solar power purchase agreements (PPAs) down 87%, a panel of experts argued that hybrid solar-plus-storage projects are now the only bankable path forward.
Chinese Academy of Sciences developing thermoacoustic heat pump for industrial applications
The researchers developed a heat-driven thermoacoustic heat pump that can purportedly achieve a temperature lift of 125 C. It uses a thermoacoustic heat pump to stably release the heat from the engine unit. The system also includes a thermoacoustic engine unit and acoustic resonators.
Enphase introduces 97.5%-efficient microinverter based on gallium nitride tech
The inverter is designed for three-phase grid configurations without using external transformers. It contains gallium nitride technology, a first for Enphase’s microinverters.
California now hosting canal top solar-plus-storage plant
California has completed the 1.6 MW Nexus canal-top solar pilot, adding a 75 kW iron-flow battery system as part of a $20 million state-funded project to test water and energy benefits.
Solar surge hits most of Europe in August
In a new weekly update for pv magazine, Solcast, a DNV company, reports that August 2025 marked one of the most productive months for European PV this decade, particularly across the western half of the continent.
Lack of information, financing among barriers to UK’s heat pump adoption
A questionnaire and focus group study of households in the UK city of Bristol found residents have a lack of access to technical and ‘common sense’ information on the transition to heat pumps. Able-to-pay residents became more willing to invest as they learned about the technology.
Uncovering attitudes towards agrivoltaics via community engagement
An American research group has conducted a pilot workshop for agrivoltaics stakeholders in Arizona, including farmers, developers, government officials and indigenous leaders. A reflection paper offers some key takeaways for future public participation.
Vertical rooftop PV deployed in Spain with east-west orientation
Norwegian vertical PV specialist Over Easy is developing several vertical rooftop PV projects in Spain. It said one of the projects, a 2.4 kW vertical, has an east-west orientation and is located in the Elche business park, near Alicante, in the southern part of the country.
Yunt releases MPPT module with 4 independent trackers for C&I use
The Chinese company says that the new product is available in 40 kW, 50 kW, and 60 kW versions. The product has a maximum efficiency of 99%.
Powering ferries with floating PV, hydrogen
Scientists in Malaysia have conducted a techno-economic-environmental study of a green fueling system for a ferry that runs between islands in their home country. Using 40,000 solar panels, they were able to power two round trips round-trips per day. Annual CO₂ reduction was measured at 23.75 million kg.
