Some interesting points:
About one in five Australian homes has installed rooftop solar. BUT
The ANAO (Australian National Audit Office) found 1.2 per cent of rooftop solar installations have been inspected by the regulator.
The regulator's inspections found that about one in six solar installations was "substandard", and about one in 30 was "unsafe".
Based on the sample, the audit found there would be hundreds of thousands of substandard installations and tens of thousands of unsafe solar systems across the country.
(Dr McCann who runs one of the few labs in Australia that conducts commercial testing for solar panels) said Australia does not have a rigorous culture of testing imported solar products.
Quote:
"When there's no expectation that your product will be checked, then there's a little bit more flexibility … to ship out the poorer-performing product that inevitably results from any production line.
"Australian consumers are notorious, and known overseas, for caring a lot about price and not caring about quality, and when that happens you get the cheaper product. And the cheaper product is not the better-performing product."
I was also really surprised to read this re household batteries for solar:
About 60,000 home batteries have already been installed, but there is still no agreed Australian Standard setting out the minimum safety requirements for their installation.
