In a new weekly update for pv magazine, Solcast, a DNV company, reports that solar irradiance in the British Isles reached up to 35% above the norm during the first half of May, while The Netherlands, Belgium, and Germany each recorded irradiance levels around 25% above average.

Australia’s Thesium has launched a new product designed to help solar farm developers de-risk and accelerate their projects, which includes a credit feasibility analysis and board-ready stakeholder documentation.

An electrician in South Australia has been convicted and fined for providing false or misleading documents in the nation’s small-scale renewable energy scheme.

DIYers can assemble the frame and modules themselves, according to the supplier. A 5.34 kW system with glass-on-glass modules from Trina Solar is available in Germany starting at €5,999.

pv magazine is compiling a guide to home solar installations, aimed at those who are interested in installing but are new to the market and want to make an informed decision. We have spoken to associations, installers and industry specialists in major solar markets across the globe to compile best practice guidance and advice that aims to be applicable to home solar installations anywhere in the world.
