Switzerland introduces winter electricity bonus for solar installations
Switzerland is implementing a new winter electricity bonus for solar installations larger than 100 kW that generate over 500 kWh/kW of electricity in the winter half-year from October 1 to March 31. The country’s Federal Council has also raised the target for electricity generated by photovoltaics to 18.7 TWh by 2030.
Pakistan needs to declare a ‘battery emergency’
Solar association chair argues urgent battery energy storage deployment is key to supporting continued PV boom in Pakistan. Residential solar CEO predicts surge in behind-the-meter storage demand if and when Pakistan’s generous net metering policy is wound down.
Sungrow unveils new modular C&I battery with long-duration storage capability
The new 12.5 kWh pack-based design supports flexible configuration up to 250 kWh per system. An optional long-duration combiner box supports 2–4 clusters, expandable to 1,000 kWh and 8 hours of storage.
UK adds 1.9 GW of solar in 12 months
Latest government figures record 20.7 GW deployed PV capacity at the end of October 2025, up 10.4% in a 12-month period. Surge in contracts for difference (CfD) supported connections recorded in 2025 with more large ground-mount projects in the pipeline.
IRENA seeks consultant for solar feasibility study in Ukraine
The International Renewable Energy Agency (IRENA) is seeking a consultancy to conduct a feasibility study for a utility-scale solar plant in Ukraine, with applications due Dec. 23.
