Electricity demand has dropped so much that Australia currently has at least 3 major coal fired power stations more than it needs! (This year the surplus capacity at peak demand is estimated to be around 8,000 megawatts)
In early July this year there was actually zero demand for power station generation in Queensland, mainly [read more…]
Conventional wisdom has been that you needed a North facing roof to mount your solar panels . . . . . . but it might be time to re-think!

There is a lot of marketing information around about Grid Connected Solar Panels but not many independant facts. Here’s an example of an evaluation of a basic system for a house.
We use around 16kw hours (kwhr) of electricity per day which is fairly typical; For each 1kw of solar panels we can expect [read more…]
For each kw of installed capacity of solar panels on average you can expect to generate 3.5kwhrs per day. This can however vary considerably for a variety of reasons.
On a peak summer day you may be able to generate 6 or 7kw hrs per day.
In winter it can be quite different. [read more…]
Several people have commented that my panels look different to those on other houses.
Most solar PV installations use Mono-Crystalline panels, because they are smaller for the same power rating. However the panels on my roof are Kaneka Thin Film Panels.
Here are the reasons why:
