Fighting coastal corrosion
Salt in the air can wreak havoc with projects that lack the necessary corrosion resistance, proving costly for asset owners or the engineering, procurement and construction (EPC) companies that built them. Alexander Gebert, sales director at Tobsteel, argues that quality stainless steel fasteners can save costs for solar investors and engineering, procurement and construction (EPC) contractors in the long run.

Why German energy provider Rabot Energy is selling a 2 kWh AC-only battery, no solar required
Rabot Energy launched Rabot Flow, a 2.12 kWh plug-and-play home battery for German apartment renters that uses dynamic tariffs to charge when grid electricity is cheap and discharge during price spikes. Sold at cost and requiring no electrician or smart meter, the Marstek-based battery promises around €120–€130 in annual savings while helping Rabot boost customer retention and grid flexibility.

‘I make a point of thanking people for asking critical questions and disagreeing openly’
This week, Women in Solar+ Europe gives voice to Hanna König, Head of Division Project Execution, at Germany’s Enertrag SE. She says the most important element of an inclusive organisational culture is ensuring that everyone feels safe to contribute ideas and opinions, particularly when they disagree with the majority or with people in more senior positions.
Sunny north and cloudy south as Super El Niño defines South American winter
In a new weekly update for pv magazine, Solcast, a DNV company, reports that Super El Niño drove a sharp north–south irradiance divide across South America in winter 2026, with sunnier conditions in the north and persistent cloud reducing solar irradiance across much of the south. Two rare August snowstorms in Chile’s Atacama Desert also caused likely snow-related losses for solar PV assets, alongside severe rainfall, flooding, and mudslides.

South Korea forecast to add 3.5 GW of solar in 2026
The Export–Import Bank of Korea says the country is on track to add more this solar this year than last year, as the Korean government works on developing a distributed power grid that facilitates greater integration of distributed energy resources.
Chinese PV Industry Brief: Tongwei clears antitrust hurdle for acquisition of polysilicon competitor Qinghai Lihao
In other news, Longi said its operating conditions are expected to improve after a CNY 3.68 billion ($542 million) first-half loss, while GCL SI and Ant Digital Technologies agreed to develop an AI-enabled carbon-management platform. JinkoSolar, meanwhile, proposed renaming its overseas parent Jinko Holdings Limited as it expands beyond solar manufacturing into strategic investments.
The Hydrogen Stream: AEM electrolysis could deliver hydrogen at $3.27/kg, say Repsol, P2HP
Power to Hydrogen (P2H2) and Repsol completed a 1,250-hour pilot of P2H2’s hybrid AEM electrolyzer technology, demonstrating operation at 40% to 100% load, pressures up to 30 bar and hydrogen purity of up to 99.9%. P2H2 projects an LCOH of €3.86 ($4.47)/kg, potentially falling to €2.82/kg under optimized renewable energy conditions, and the companies are considering a 500 kW-to-MW-scale demonstration.
