What is the Australian Sun Tax?

When we first had our solar system installed after moving into our house here in Australia, one of the big “pushes” was the face that we would be paid for any excess energy that we produced. This was the big “selling feature” in Australia by the government and all the solar retailers.

Well, turns out it was a “saying when an agreement is tricked and reversed”

A hidden “Sun tax” slugging Aussies who have made the switch to solar has been slammed by energy advocates as “madness” and a “rip-off”, accusing energy companies of “wanting to charge people” making energy from sunlight.

Distributors in some Australian states have moved in the sneaky tariff, known colloquially as a Sun or solar tax, as households begin to embrace the shift to renewables in the hopes of power bill relief.

But the new measures will result in those households being slugged for sending the solar energy they generate back to the electricity grid during peak times – something providers hope will encourage households to store their self-generated power and use it, rather than hoping for a credit if it is exported back to the grid.

A Sun tax refers to a new export tariff for customers using solar, part of a two-way pricing structure where users are effectively penalised for exporting solar-generated energy when the network is overloaded – such as in the middle of the day.

Already since we have seen the amount that we are paid for electricity that we feed into the grid cut to a pittance of what it was. And now they are planning to charge us for any electricity that we feed into the grid during the middle of the day, when the sun is at it’s peak.

The solution that the energy companies suggest are for consumers to spend $9,000 – $25,000 for a battery backup, which most people simply can’t afford!

In addition to some retailers now charging users when they export power, in the last few months they have increased the supply fee by 50%! Since the supply fee is fixed, users have no choice but to pay it, regardless of how much power they use.

Should I Clean My Solar Panels?

It’s coming to the time of year that we get reduced cloud cover and a lot more sunshine. This will mean that our solar panels will start to generate more power again, which is helpful. It’s been quite a while since I last cleaned them, so last weekend I picked up a soft bristle brush to have a go at cleaning them.

The last few times that I have cleaned the panels I have just hosed them off, letting the water pressure from the hose do the work of cleaning the solar panels. However this year I’ll be giving them a scrub to really clean them up.

I was curious about what kind of performance increase I would get from cleaning them, and after watching the below video, I reckon it’ll be pretty significant. Paul on the video managed to get a performance increase of about 30 – 40%!

Cleaning the solar panels should help a lot, especially with the ridiculous high cost of electricity here in South Australia…

Ready to Pay At Least An Extra $250 for a Table Saw?

In a lawsuit in the United States (where else eh?) this week a man was awarded $1.5 million USD for an injury to his fingers that was caused by a table saw. The man injured his fingers while using a Ryobi table saw when he was installing oak hard wood flooring in 2006.

The thing is, there was nothing wrong with the table saw. The table saw didn’t fail to function as designed, or break, or have anything wrong with it. The Ryobi table saw met all current safety standards. The problem was that is was not equipped with a flesh detection technology to stop the blade!

Personally I reckon the guy must have been an idiot who should never have been operating a table saw in the first place. Also the people on the jury must have never used power tools before, or something, because I really can’t understand how this could possibly have happened!

If the lawsuit sets a precedent then we can expect to see all table saws in the future equipped with flesh detection technology. This will probably add at least $250 to the cost of a low end table saw, and more to the higher end more expensive table saws.

I think that the flesh detection table saw, currently made by SawStop, is a cool invention. It would especially be suitable for wood working shop classes in school (we had a shop teacher at my old school cut off his fingers, not a good example). I don’t think though that it should be required on all table saws.

The cost is extremely prohibitive for the table saw technology. The additional cost for the flesh detection technology will be about $250.00. Not only that, but if the technology is triggered you will need to replace the brake mechanism and the blade. Unfortunately the mechanism can be triggered by something as simple as moist wood, which would cost you about $150 depending on the blade.

Sustainable House Day in Australia

This Sunday is Sustainable House Day here in Australia and over the Tasman in New Zealand.

Sustainable House Day is a day when all around the country people living in sustainable housing will open their doors for people to visit their homes.

There will be people available to answer questions about what they did to make their homes sustainable, and what you might be able to do to make your own house more sustainable.

There seems to be a real cross-section of homes and people participating in Sustainable House Day. Here in Townsville there are two homes that are participating:

  • A retrofitted house built around 1970 that has has modifications done to make it a more sustainable home
  • A purpose built house built in 2001

Each of these homes offer two very different avenues to pursue when making your house more sustainable.

Sustainable House Day focuses a lot of attention on solar issues. This includes the passive solar design of the house (shade, eves, insulation, etc.) as well as the active uses of solar, including solar hot water and solar electricity.

The event is put on by ANZSES, the Australia New Zealand Solar Energy Society, hence the focus on solar issues.

You can find out more about Sustainable House Day here, and you can see if there are any houses available for viewing in your area here.
