Job Vacancies

We are increasing our staff and have positions for sales and installation staff. These positions are open to Australian residents only. See our current vacancies.

Washing Machines

For some reason many Bosch products (including some of their drills and washing machines) have problems running off even the best Aussie made sine wave inverters. Gordon Claridge wrote a good article about his washing machine experiences.

CPAP Machines

Resmed, a major manufacturer of these devices has written a good summary of the power consumption of various units running at different settings etc.

Apple Regulator

We are pleased to advise that we now have a 20A (12V) regulator in this popular range. These have proven to be a very reliable and economical regulator with a dozen status LED indicators and a low battery warning alarm.

Battery Prices

Some bad news for you is that batteries have gone up a lot in the past couple of months and are predicted to go up a further 5% in January! We are now finding that the batteries are costing more than the panels on a new system! The really begs the question whether one is better off buying extra PV and reducing the battery capacity.

Incidentally, Australian residents whose principle place of residence would cost more than $30,000 to connect to the grid may be eligible for a 50% rebate to upgrade their system with new batteries and more solar panels (450W minimum purchase required).

More information on rebates and incentives.

New Solar Technologgies

We all hear about new solar inventions quite frequently on the news, television etc. There has been a lot of research into solar technology for the past 20 years. Inventors often 'talk up' the benefits of their technology to try and obtain grants and venture capital.

We are often asked 'should I wait for this new solar panel I have heard about . . . . '.

The first point I'd make is that we've been hearing such stories for decades and we are still basically using the same technology today that was first produced decades ago.

Secondly there is a world shortage of solar panels which tends to set a world price for them. Why would anyone sell them at a bargain if they don't have to?

Thirdly, any new technology will take years to test and to bring it into commercial production.

Fourth, they often talk about increased efficiency - this is different from 'cheaper' - it just means they will take up less room.

Fifth, the largest world producers of the current technology such as Sharp, Kyocera, Suntech and BP are still expanding their investment in current technology factories.

To conclude, we recommend you stick with the current technology which is tried and proven.

Solar Cooker Special

For Christmas, we have discounted our Solar Box Cookers (while stocks last). These work well, are portable and even come with a recipe book!

Cheers from Dave and all the RPC crew.

Dave Lambert (Director)
