We previously wrote an article about the feasibility of an Australian home going off-grid with a 3kW solar system – quite a small system size for such an ambitious endeavour. In this article, we’ll look at the case for going off-grid with a 10kW solar system – the unofficial upper limit for residential solar system […]

Thumbnail image for Going with the flow: An introduction to redox flow batteries

Renewable energy technologies – solar PV in particular – are on the cusp of changing the energy landscape. In combination with the right load profile and in the right settings, solar‑powered electricity has reached a point where it is more cost‑efficient than combustion generators. But to make that next big step we need to find […]

The solar world is abuzz with the advantages that energy storage systems can bring to solar owners. In Germany alone, their support for solar storage has resulted in more than 4000 systems being installed so far this year. In Australia, we don’t have any mechanisms to support solar storage systems (yet) but sales are slowly […]

Five billion reasons why independent power makes sense

March 10, 2014

Australia. Often described as modern, sophisticated and of course, sunny; a country with 22 million smiling and suntanned jokers. What you may not know is that almost half a million Australian’s (1.8% of our population) are not connected to the National grid. A recent study by the Bureau of Resources & Energy Economics has given […]
