Harald Scherleitner discusses Fronius's return to growth, the strategic case for building in Europe and why cybersecurity has become a defining purchasing criterion for inverters.

Rooftop systems and batteries will be taxed at 5 percent again from April, while cuts to the Warm Homes Plan mean less help for households investing in clean energy.

In just its second year, the Croatian event drew more than 5,000 visitors and growing numbers of suppliers looking for partners across south-eastern Europe.

PV Guided Tours: The three-phase Powerwall 3P battery delivers 15.4 kW of AC output and adapts flexibly to demand. Behind it all sits the Tesla Home energy manager, which links the battery, PV system, EV and heat pump – all optimised by AI software.

C&I storage with built-in backup from Hoymiles, AI-supported home backup from Sigenstor Neo, 261 kWh cabinets from Clou and Midea and more capacity from Solarwatt’s Battery Vision 2.0, all new this week.

Solar park construction is picking up pace worldwide, but the bottleneck is not materials or components. It is land, grid connection points and the people to do the work. Sign up for our investor newsletter to receive this digital edition directly.

CEO Talk: the most efficient kilowatt-hour of solar power is the one used on site. That calls for clever ways of integrating a wide range of components as flexibly as possible: heat pumps, EV charging, air conditioning and more. How can buildings make maximum use of the solar energy on their roofs? Find out in the video. (German with English subtitles)

Lithium-ion storage carries real risks of thermal runaway, fire and explosion. Certified technical containers can shield installations from external hazards and ease the route through building approval processes.

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.

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.

Capacity, cycle life and price dominate most battery comparisons. Randy Levine of SolarClarity.co argues that the household’s electricity tariff decides whether storage is worth the money. 

PV Guided Tours: Sigenergy presents its system approach for energy and infrastructure projects. From 1,000-volt AC technology to intelligent energy management, the innovations lift both the efficiency and the returns of solar projects.

Usable capacity per module rises from 2.6 to 4.3 kWh, a 42 percent increase, with towers scaling from 8.6 to 259 kWh across up to ten units.

Energy costs shape competitiveness in both global and local markets. As fossil and nuclear prices continue to rise, solar and wind are no longer marginal technologies but increasingly represent the smart money in power generation.

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.
