Solar panels have gone through somewhat of a craze over the last 5 years. From just 20,000 rooftops in 2008 to more than 1,000,000 rooftops in April 2013, that is an increase of 4,900%. But even with this massive growth, it still only accounts for 1.2% of Australia’s electricity needs. This increase will naturally slow down since NSW has scrapped its overly generous Feed-In-Tarrif scheme.
Still, there are approximately 10% of all houses fitted with the panels according to the Clean Energy Council. This equates to enough electricity being generated by renewable sources during this period to power the equivalent of more than 4 million Australian homes.
The price of panels has also been going down, though we could wish they went down as fast as the increase in number of installations. This was due to the price drop from the Chinese manufacturers who flooded the market.
In New South Wales, the Independent Pricing and Regulatory Tribunal (IPART) was investigating the controversial solar feed-in tariffs, and are now reviewing submissions in the determination of a fair and reasonable value for electricity generated by small scale PV systems for 2013-2014. According to IPART the fair and reasonable value determined by IPART must not result in any increase in electricity prices in New South Wales, and must not be funded from the New South Wales Government budget.
Energy Matters has calculated that if all 400 sq.km of available roofing were to be used for solar panels the amount of energy produced would supply around 135% of Australia’s residential electricity needs. They said this would lead to a decrease in electricity prices – the cost being just 7 cents per KWh. Currently the cost is around 40 cents per KWh (depending on location and provider).
Australia has just one manufacturer of solar panels left – Tindo Solar, based in South Australia. Although small by world standards – they employ just 16 people – they have capacity to manufacture 200,00 panels a year.
