Fraunhofer presents solar module cleaning tech using structure-borne sound
Fraunhofer Institute for Digital Media Technology IDMT has developed a solar module cleaning system that uses structure-borne sound and targeted mechanical vibrations to dislodge dust. Researchers will present the technology at Intersolar Europe in Munich from May 7 to 9.
Alight inaugurates Sweden’s largest solar park
Swedish independent power producer Alight has completed a 64 MW solar project near Stockholm. The site in in Hallstavik is now the largest PV facility in the country.
Togo breaks ground on solar-plus-storage project
Togo has begun construction on a 25 MW solar plant with 36 MWh of battery storage in the country’s north. China’s TBEA International Engineering is leading the project, which is scheduled for completion within 13 months.
UK rooftop solar has strongest Q1 since 2012, new record for generation in April
Building regulations in England support growth in demand for rooftop solar as new-build properties make up significant share of small-scale PV installations. Strong installations in first quarter of 2025 were followed by a new single-day record for UK solar generation in April.
Biwatt releases 4.5 kWh sodium-ion battery
The Chinese manufacturer said its new IP65-rated product has a lifetime of 5,000 cycles. Up to four batteries can be stacked together, with total storage capacity reaching 72 kWh.
Colombia approaches 2 GW solar capacity milestone
Colombia is approaching 2 GW of cumulative installed PV capacity, with 1.34 GW currently operational and an additional 700 MW in testing, according to the country’s grid operator.
AI-driven robotic piling tech supports 250 MW solar project in Australia
Bouygues Construction Australia (BCA) is trialing an autonomous piling system (APS) to build Engie’s 250 MW Goorambat East Solar Farm (GESF) in Victoria, Australia.
How to integrate solar-plus-storage with heat pumps
Scientists in Spain have simulated a system that uses both power-to-heat-to-power thermal batteries and lithium-ion batteries for energy storage. The hybrid system reportedly achieved a 7% lower LCOE compared to a PV system relying solely on lithium batteries, while simultaneously increasing PV self-consumption by up to 20%.
Avaada to develop 3.65 GW of pumped hydro storage in India
Avaada Group has signed an agreement with the Maharashtra state government in India to build two pumped storage hydro projects with a combined capacity of 3.65 GW. The company plans to deploy the projects in phases to support grid stability and renewable integration.
