‘I have become less tolerant of the high-five lad culture’
This week Women in Solar+ Europe gives voice to Liz Cammack, CEO of UK’s Cammack Consultancy Ltd. She says diversity and intentional inclusion are essential to innovation, requiring leaders to look beyond familiar talent pools, challenge bias with evidence, and build teams with genuinely different skills and perspectives. Drawing on her own career, mentors and experiences, she encourages women to reject cultures that limit them, embrace every opportunity to learn, and build strong networks that help others succeed too.

England and Wales lead western Europe’s record summer irradiance
In a new weekly update for pv magazine, Solcast, a DNV company, reports that Western Europe saw its strongest summer solar resource since at least 2007 in 2026, with GHI 6.9% above average and England and Wales nearly 16% above average. Persistent heat domes brought clear, hot, and exceptionally dry conditions, with temperatures over 2 C above average and severe rainfall deficits, particularly in July.

The case for railway-integrated solar in South Korea
South Korea’s extensive railway network could provide new space for solar generation in densely populated areas where land availability is limited. Researchers have investigated the potential of installing PV systems between railway tracks, finding that suitable sections of five surface railway corridors could host more than 8.5 MW of solar capacity.
Japan tightens grid access as battery queue reaches 172 GW
Japan now requires generators, including battery developers, to prove rights to their sites to keep a grid connection, as regulators move to curb capacity hoarding in a battery queue that far outruns the less than 1 GW of grid-scale storage actually connected.
France hits record 800 hours of negative, zero electricity prices
France has recorded around 800 hours of negative or zero electricity prices in 2026, as growing market volatility creates new opportunities for battery storage. Storio Energy says widening daily price spreads have boosted battery spot-market revenues, amid lower nuclear, wind and hydropower output.

Spacebound silicon
Solar has a long history in powering satellites and space exploration, and high-powered devices based on multijunction PV cells made from “III-V” materials such as gallium arsenide or indium gallium phosphide have supplied this niche market as far back as the 1960s. But those devices are made with rare materials and complex processing, limited to small batches produced at high cost.

Age awareness for BESS
As the use cases for battery energy storage systems (BESS) evolve, so does the way the batteries are operated. How these changes affect BESS lifetime and reliability is a question the industry needs answered, and one the International Energy Agency’s Photovoltaic Power Systems Programme (IEA-PVPS) is working to address. Erik Marstein, director of Norwegian PV Research Center FME Solar, outlines the results of recent research into BESS reliability and how asset owners can take system aging into account in daily operations.

Module cooling: too hot to handle
Even after the record-breaking heat waves of this summer and associated performance losses at PV plants across the northern hemisphere, active cooling for solar arrays remains a difficult market prospect. Developers might be a bit more interested in preventing temperature-related losses, but in most cases, the numbers still don’t quite add up.
