Advances in solar power technology (letter)

by John Urquhart

News Weekly, August 2, 2008

In relation to Lyndon Burns' letter on renewable energy (News Weekly, July 5), I would like to join issue only in a minor way.

I reside on a property in the south-west of Western Australia where there are no normal facilities supplied by government or local government. Thus, we rely on solar power with diesel generation as a backup. The plant was first installed in 2002, and included in the system were 24 solar panels.

We had the unfortunate experience of suffering the effects of a severe bush fire in January 2006 which destroyed our solar plant.

The replacement panels were nine in lieu of 24, occupying just over one third of the area of the previous panels. Technology had obviously advanced considerably in four years which, to my way of thinking, has resulted in less pollution involved in manufacturing the latest panels and also less silicon used.

The technological advancement in this area may mean in the future that solar energy will become a feasible source of wide-scale electricity generation.

However, in the mean time, the present technology could be used by householders and industry to augment the present methods of electricity supply.

It is a pity that this approach is not more actively promoted by governments.
