CEO Talk: The utility business in Europe is growing and increasingly challenging. Solar fields now come with large batteries, and suppliers must meet standards for grid compliance, safety and security. How is the business changing and what strategy will ultimately succeed? Leon Zhang, President of LONGi Europe, shares his view.

Two identical home storage systems can deliver very different savings, depending on the household’s electricity contract, argues Randy Levine, founder of SolarClarity.co. He explains what buyers should check first.

A new module from Oldenburg-based emsys VPP opens the way for the utility to offer its batteries as frequency reserves, twenty months after the Baltic states joined the continental European grid.

Production is complete on the 60 MW/120 MWh Jonava system, which will earn its revenue from balancing services for Litgrid and trading on Nord Pool.

So much power now feeds into Spain’s grid at midday that prices often fall to zero or below. A new analysis from rating agency Morningstar DBRS shows how hard this is hitting project finance.

PV Guided Tours: Huawei’s new Luterra S2 is an all-in-one residential storage unit, installed in minutes, with AI-driven control. The company has also upgraded its commercial storage to deliver more kilowatt-hours. Watch the video for the full picture.

Clou Electronics and Midea Energy have developed a C&I storage unit for Europe that combines 314 Ah cells with pack and cell-level cooling and up to 90 percent efficiency.

The era of petrol and diesel dominance is drawing to a close. Mobility is transitioning to electric, with millions of private electric cars, company fleets, and commercial vehicles creating new demands on the energy supply. Filling stations, parking garages, and parking lots now represent opportunities to provide EVs with solar power.

PV Guided Tours: Speed and simple handling are what installers demand of rooftop mounting. With versatile substructures and just a handful of tools, modules can go onto virtually any roof in record time. Sounds too good to be true? Watch the video.

Lightweight warehouse roofs, vehicles, noise barriers, greenhouses and indoor IoT devices could all become markets for perovskite solar. A new IDTechEx report looks at the decade ahead.

Ukrainians have lived with Russia’s full-scale invasion for years. Since September, attacks have grown more frequent and more brutal. With winter approaching, help is needed more than ever.

Bids open on 29 October in the first Irish auction with a separate pot for solar, new EU rules on how bids are scored and extra points for battery storage.

Over two years on Lake Constance, Germany's Fraunhofer ISE found that fewer fungicides and quicker manual work more than make up for slightly lower apple yields, before counting the income from the solar modules.

PV Guided Tours: Gotion’s new Grid Q battery system can help stabilise the grid as well as store energy. In this video, we find out how the company is bringing local storage production to the European market.

Sigenergy's new all-in-one battery offers up to 15 kW in three-phase configurations, LFP modules of 6 kWh and 8 kWh and outage protection for essential household loads.

Investing in solar parks, expansive rooftop systems and cutting-edge battery storage requires patience and a genuinely long-term outlook. Such projects are generally designed to run for twenty years or more, making it crucial to safeguard them against a broad spectrum of risks over their lifespan – an important issue that is still too often neglected.

PV Guided Tours: Energy management systems integrate not only solar installations and storage but also electric vehicles through bidirectional charging. How does it work, and which functions do such systems offer?

Commissioned by Fluence, the study finds flexible capacity from a battery costs $371 million over 25 years in Texas – under a third of the price of gas and a sixth of diesel.

Trina Storage has commissioned its first battery storage project in the Portuguese market. Developed with independent power producer Prosolia Energy, the 15 MW/60 MWh system in the Centro region is paired with an existing solar plant.

The bank is taking a minority stake of up to US$221 million in the Norwegian developer’s investment vehicle, which is lining up 2.7 GW of solar and 900 MW of wind in Egypt, with more projects planned across the southern and eastern Mediterranean.

Households are stacking solar, batteries, EVs and heat pumps from different brands, only to find the devices can’t communicate with each other. Jochen Schwill of SpotmyEnergy argues that compatibility should become a defining measure of quality.

CEO Talk: instalment purchasing made easy. With solid partners behind them, installers can offer customers loans for their solar setup alongside the build itself. What does this mean for installers? More work or more orders? Watch to find out.

The Hoyultra 2000M stores up to 2.61 MWh in a single cabinet and switches to backup power in under 20 ms, with Hoymiles promising installation in less than a quarter of the usual time.

Roofs and flat open spaces aren't the only options for solar power. Applications that pose particular challenges for project planning and installation technology are increasingly coming into focus.

More than 75 module assemblers operate across the continent, against just one ingot-and-wafer project and one polysilicon producer. Now over 35 industry players want the Industrial Accelerator Act to fill the gaps.
