Large backup batteries that check their charge at the start of each minute cause a regular dip in frequency worldwide, Jülich researchers report after a search lasting several years.

The battery specialist, which has already supplied more than 300 units to regional grids, went to Zagreb’s Green Energy Fair to find new installers and launch new C&I and utility-scale systems.

CEO Talk: Utility-scale solar projects across Europe are under growing cost pressure, even as expectations around yield, grid integration and long-term profitability continue to rise. Which new ideas boost project value, and which innovations matter most to the market? Let‘s find out.

The new Solarbank Max extends the manufacturer’s range of balcony and home battery products. Three MPP trackers take a solar input of up to 10 kW, enough for up to 20 solar modules.

A Biohaus Foundation truck packed with solar modules and batteries is due to leave Paderborn for five sites across Ukraine. Among them are hospitals in Kyiv, Sumy and Trostianets, which will need power they can rely on as winter approaches.

How do you convince a CFO to commit to a fixed electricity price for the long term? At RE-Source 2026, a panel of buyers, sellers and advisers set out what works, what fails and why the internal process often matters more than the deal itself.

From 12 to 14 January, Ptak Warsaw Expo will host the sixth edition of the show, with Huawei Polska, Sigenergy and Ingeteam among the exhibitors, and a dedicated zone for installers looking for new partners.

Venture capitalists are back and putting larger sums into fewer early-stage companies, while acquisitions and new EU cybersecurity rules are changing how startups grow.

A new whitepaper finds industrial flexibility could cut EU renewables curtailment by 61 percent and avoid 60 GW of peak capacity, while opening new revenue streams for energy-intensive sectors.

Europe's grid queues hold 1,700 GW of stalled projects. Sharing connections between wind and PV could ease the bottleneck, but regulation, permitting and grid operators keep hybrid parks a rarity, explains Philipp Rasche of ENEO.

From shared connection points to AI-driven trading: two very different perspectives on Europe's grid capacity problem, and how developers and operators can make better use of existing grid capacity, cut curtailment losses and lift returns on renewable assets.

A growing number of hacker attacks is exposing weak points in solar systems. Operators who act early can keep attackers out, while delay risks costly failures and disruption to the grid.

With 406 GW of solar online and a few cloud platforms steering much of the fleet, Brussels advisers want tighter rules on where inverters and firmware come from, and who supplies them.

CEO Talk: Installers and EPCs are facing dual pressure. Project sizes are growing and installation windows are tightening, while demands regarding quality, reliability and safety are rising. How are mounting system providers responding to these challenges? Here’s what they told us.

A joint webinar by K2 Systems and PV Europe sets out how installers can tackle the competing demands of speed, flexibility and plant protection when building large solar arrays on flat and green roofs. It is now available to watch free of charge.
