There is a touch of spring in the air which should please most people after a very cold winter. All we need now is some lovely rain.
1) Battery Prices
Unfortunately batteries are continuing to rise in price due to the world price of lead. On large systems which we design, we are now sometimes seeing the batteries costing more than the solar panels! It certainly reinforces the view that one should take good care of their batteries. Fortunately regulators have come a long way in the past few years. They help to look after your batteries better and help you to monitor their situation more effectively.
2) New Rebate
The new RRPGP rebate guidelines and application forms are finally available. This is for people living remote from the grid and supplies power to houses, non-profit organisations and businesses. Upgrades to existing systems are also possible. The guidelines are complex, so I won´t try and explain more. Have a look at: http://www.rpc.com.au/rebates.html
3) Hybrid Vehicles
Toyota has expanded the use of its hybrid systems to minivans, SUV´s, rear-wheel-drive sedans and other vehicles and has had increased sales worldwide. Toyota Australia set an all time monthly record in May 07 with Pruis sales, said to be as a result of both increased availability and greater environmental consciousness. Toyota claims they have (since 1997) reduced emissions by some 3.5 million tons of CO² compared with the same class gasoline-powered vehicles of similar size and driving performance.
4) Halogen Downlights
Murray C commented on last month´s article that besides using a lot of power and generating a lot of heat, they can start fires in poor installations (of the lights and/or ceiling insulation). They can reach a temperature of 370C and use 80% more power than compact fluoros.
5) Feature Article
This article about my house is written to try and give our grid connected friends some ideas on our how to become carbon neutral. Hope you find it useful.
