Key takeaways from Spain’s Genera tradeshow
Spain’s Genera 2025 trade fair highlighted advances in solar, storage and grid-forming technologies, along with industry calls for clearer regulation, stronger market design and faster permitting to support future deployment.
How to balance power losses, cost effectiveness in PV-BESS-driven EV charging stations
Scientists in India have developed a novel method to optimize the placement of an EV charging station on the grid, along with the size of its PV generation and battery storage. They have also created a framework for an innovative slot offering.
Solar provides predictable income stream for farms
Solar farm leases provide stable, predictable income that helps financially secure family farms and boosts rural tax revenues with minimal land impact, said a report from the SEMA Coalition.
Panasonic launches new air-cooled heat pumps
The heating and cooling business of the Japanese giant has released a new range of heat pumps for commercial projects. The systems have capacities of 40 kW and 50 kW.
Paraguay set to host autonomous solar-powered data center
Sollar Machine plans to build a $9 million off-grid data center in Paraguay powered entirely by solar and batteries to deliver high-performance computing services for international clients, with a focus on AI.
Cash flow analysis shows adiabatic compressed air storage is viable for 10–100 h applications
Scientists in the United Kingdom have compiled a new database of adiabatic compressed air energy storage projects. Using this data, they were able to determine the experience rate and identify the conditions under which the technology would be economically viable. According to their findings, costs have declined at a 15% learning rate since 2013.
Chinese scientists build 18%-efficient organic solar cells with enhanced stability
Chinese researchers have demonstrated organic solar cells with novel encapsulation and a protective interfacial layer for enhanced stability and efficiency. The best performing cell based on the new approach retained 94% of its initial power conversion efficiency after standards-based damp heat testing for 1,032 hours damp heat and across 200 thermal cycles.
World’s largest foldable rooftop PV system comes online in Switzerland
A wastewater treatment plant in the canton of Bern has been inaugurated with what dhp Technology claims is the world’s largest foldable rooftop solar installation to date. The 3.6 MW array spans several treatment basins, allowing the existing site to serve dual purposes: wastewater treatment at ground level and solar power generation overhead.
Hydro approves largest pumped hydro project in more than 20 years in Norway
Norsk Hydro will invest about $110 million after tax to build the Illvatn pumped hydro plant in western Norway.
Germany’s January-October solar additions reach 13 GW
The Federal Network Agency (Bundesnetzagentur) says Germany’s installation pace reflects shifting demand patterns between ground-mounted and rooftop PV systems.
