The Institute for Energy Economics and Financial analysis (IEEFA) has published a report in which it points to seven key lessons energy planners the world over can take from South Australia’s extraordinary renewable energy integration. However, even South Australia, IEEFA’s model, still requires thoughtful planning and policy for the path forward.

The system, developed by Spanish specialist Alusín Solar, is being tested by Endesa in a 9.8 MW project for self-consumption. The mounting structure is made with aluminium bars that, instead of being fixed to the roof with screws, are attached through a double-sided adhesive.

Scientists in China developed a new kesterite solar cell they say could be suitable for indoor or outdoor applications. The bifacial solar cell reached 9.3% frontside efficiency, and also achieved a 9.0% on the backside.

Chief Executive of the Australian Renewable Energy Agency, Darren Miller, says he envisions a future where Australia will produce up to ten times more clean electricity than the country requires to become a “shining example of what is possible if you have the right ingredients and the right ambition.”

The Housing SA Tesla VPP is being expanded to include a trial of 20 homes unsuitable for solar installation. The SA Government is offering free Tesla batteries to such homes to show how participation in the VPP with a battery alone can still deliver significant savings.

A German PV system owner has developed a simple solution intended at preventing the birds from nesting under the modules.

Last week, testing specialists PV Evolution Labs launched its latest Module Reliability Scorecard, which names more than 100 products from 26 manufacturers as top performers, after being put through their paces in extensive lab testing. This year’s scorecard reveals an increase in modules seeing at least one failure during the testing procedure, with newly added mechanical stress procedures causing the greatest number of failures.

The Chinese module manufacturer said the 0.35% improvement in efficiency was obtained through material upgrades integrated into the cell process and fabrication. The result was confirmed by China’s National Institute of Metrology.

A Swiss start-up has created a containerised movable PV system that is designed to be easily relocated to allow the use of solar energy in locations where a fixed installation is not an option. The solution is based on a racking technology which can include two racks able to host up to 30 solar panels.

TransGrid and ElectraNet have shovels at the ready to begin work on the long-planned and hard-won Project EnergyConnect, which will link three Australian states with much needed capacity for transmission of renewable energy.
