Germany led the way with the UK and Bulgaria tied in second place, followed by Spain, Hungary, and France.

The CEO of Irish PV association Solar Ireland, Ronan Power, told pv magazine that despite a healthy project pipeline and investor appetite, ground-mounted PV projects are not being delivered as fast as they could be. A national clearing house to provide more defined communication at the early stages would help developers deliver faster.

A new report from the European Network of Transmission System Operators for Electricity explores the potential for data centers to become flexible assets in Europe’s electricity system, as well as how to manage grid planning and grid security.

Grid-scale solar PV electricity generation surpassed 1 GW in mid-April, which marked a new record in Ireland according to the country’s high-voltage transmission system operator Eirgrid. Around 500,000 customers’ power needs can be met with 1 GW, Eirgrid estimates.

Ireland recorded more than 10,000 applications for solar PV as part of its home energy upgrade program from January to March 2026, an increase of 65% on the same period for last year.

Switzerland startup Evolium Technologies’ subscription-based business model offers residential battery owners a lifetime guarantee on second life batteries. The startup tests and remotely monitors each battery cell so it can alert customers when a cell is under-performing.

SolarEdge has outlined a transition pathway to integrated 800 V (DC) infrastructure for data centers, arguing that legacy alternating current (AC) systems introduce inefficiencies that could constrain the growth of AI workloads. It says rising compute demand and next-gen NVIDIA GPUs are increasing urgency, while data centers lose an estimated 10% to 30% of input power through multiple conversion stages.

Azerbaijan President Ilham Aliyev has inaugurated a major battery energy storage system (BESS) project as part of a 500 MWh rollout to strengthen grid stability and support renewable energy integration.

Following the closure of its €5.4 million ($6.23 million) pre-seed funding round, Luxembourg’s TerraSpark aims to carry out its first space-to-earth power transmission in 2028 using radio frequency-based wireless energy transmission. The company has also been selected to join Germany’s Dcubed on a mission scheduled for early 2027.

SOSV-backed Qnetic is aiming to raise $20 million in 2026. Over the next two years it will work with the National Lab of the Rockies and other partners on field testing and validating its technology across multiple use cases.
