Slovak distributor ONSA Plus has joined forces with global inverter manufacturer Solis to expand access to reliable and high-efficiency PV inverters in Slovakia and the rest of EU, addressing rising demand for distributed solar solutions in residential and commercial markets.

The Bulgarian Ministry of Energy has opened a public consultation for a new round targeting 1.9 GWh of standalone storage capacity, building on the success of its initial RESTORE procurement, which backed nearly 10 GWh of energy storage development.

Lithuania has concluded its latest energy storage procurement round with plans to deploy 1.7 GW/4 GWh, five times its initial 800 MWh target, to strengthen grid flexibility and reliability.

A village in eastern Ukraine has received a donated solar-plus-storage system to secure water access amid ongoing attacks on energy infrastructure.

Scientists in Canada studied romaine lettuce growth under cadmium telluride thin-film solar modules with varying transparency and photosynthetically active radiation, and found Germany’s regulatory framework most effective for maximizing agrivoltaic benefits.

Serbia’s solar market topped 5,000 prosumers in the first half of 2025, though no plants above 10 MW are online. The country has a gigawatt-scale pipeline and procured 124.8 MW in its February renewables auction.

New research from Poland has suggested installing 891 PV panels along the entire tram platform and inter-track spaces of four major transportation hubs. The analysis showed that the PV system could power all of the city’s tram stops, the passenger information system, and meet 10% of demand from service depots.

PGE Group has launched a tender for a 400 MW/2-hour battery energy storage system in Gryfino, Poland, expanding the state-owned company’s national storage capacity to 800 MWh.

This week, WiSEu Network – Women in Solar+ Europe reflects on SolarPower Europe’s forecast of a 1.4% drop in EU solar growth for 2025, the first decline since 2015, and why this signals more than just a market slowdown. To meet 2030 targets, we don’t just need better strategies; we need a transformation in leadership itself. That means dismantling centuries-old biases that equate leadership with dominance and detachment, and embracing a fuller spectrum of qualities: empathy, collaboration, and emotional intelligence, now recognised as essential for navigating complexity and driving the energy transition.

The combined investment from the two banks totals €64 million ($74.7 million) and will be put towards the development of two new solar farms in Lithuania each with a capacity of 91 MW.
