Will SA’s “Solar Sponge” Tariff Make ‘Batteries Without Solar’ Worthwhile?
Update 9th April 2020: South Australia Power Networks has informed us the Solar Sponge tariff is available now for people with smart meters, but very few electricity retailers are offering it.1 It was to become standard on the 1st of July, but this may be delayed due to the Coronavirus pandemic.
In October 2019 South Australia Power Networks (SAPN) announced they would introduce a new “Solar Sponge” tariff promising electricity in the middle of the day at one quarter their usual rate.

Danish Study Shows Solar Panel Optimisers Aren’t Always Optimal
Solar systems hate shade. They really do. Sometimes they talk to me in my dreams and it’s always their number one complaint, right after being pooped on by birds. But these two problems are related — they hate bird poop because it shades their solar cells. [Read more…]
How The Financial Stimulus Can Help Your Solar Business
On March 12th, in response to the economic slowdown caused by the coronavirus and bushfires, the Australian Government announced a $17.6 billion economic stimulus.

Coronavirus: More Lives Saved Than Lost Due To Lower Air Pollution
The coronavirus, or COVID-19 as all the cool epidemiologists are calling it these days, has at time of writing killed over 2,600 people in China and quarantine measures taken to slow its spread have led to the greatest economic downturn that country has seen since the Global Financial Crisis of 2008.
But in the wake of all this suffering and disruption, there is a silver lining saving many more lives than the virus is taking.
