A French research group has compared the performance ratio of 100 PV systems relying on micro-inverters with that of 100 installations relying on string/central inverters. It found the performance ratio is around 79% for both system typologies and that arrays with micro-inverters are more sensitive to environmental factors.

Fotowatio Renewable Ventures Australia’s 90 MW (AC) solar farm outside Wagga Wagga, New South Wales, has reached the commissioning phase after less than a year of construction. Barring no obstacles, the project should start exporting solar energy to the grid in a matter of months.

Western Australia has become the second state to give network operators the capacity to remotely switch off residential solar systems as an emergency grid stability mechanism.

AGL has “broken ground” at Torrens Island power station in preparation for the construction of its 250 MW/250 MWh battery which has drawn interest for being the largest planned grid-forming battery in the world.

Geelong Port, one of Australia’s major ports southwest of Melbourne, today announced it will invest $100 million to establish a hydrogen hub in partnership with biomass gasification outfit CAC-H2.

Scientists in the United States pieced together data from hundreds of different sources, looking to establish the key factors that have led to consistently falling prices for lithium-ion technology since their commercialisation thirty years ago. They find that public-funded research, primarily in chemistry and materials science, has made the largest contribution to cost reduction. And they offer suggestions on policy and investment to ensure that the research can continue to make these important contributions to reduction in battery costs.

NREL scientists have unveiled a storage system based on a phase-change material that can store both thermal energy and electricity in a single device. According to the researchers, the new technology may be used to store excess electricity produced by on-site solar or wind operations in large scale buildings.

The new plan would require the deployment of around 15 GW of new PV capacity each year to 2030. The agreement also includes the gradual phasing out of all coal power plants by the end of the decade.

Through the Green Electricity Tariff (GET) program, the government will offer 4,500 GWh of power to residential and industrial customers each year. These will be charged an additional MYE0.037 (AU$0.012) for each kWh of renewable energy purchased.

At the risk of stating the obvious, PV performance will always be inextricably linked to the weather. Cloud cover significantly influences power output and severe weather events – including high winds, heavy snowfall, fire, and hail – can lead to module or structural damage. And with climate change making extreme weather events more common, the value of forecasting and understanding the worst Mother Nature can throw at a solar array is increasing.
