Is this the daftest solar power promotion in Australia?

October 17, 2010 2017-05-03T13:52:36 by Leave a Comment

Watching the late movie on TV last night the most ridiculous ad for solar power I have ever seen came on.

I nearly fell off my sofa when I saw that if you buy a 1.5kW solar system from these guys, they’ll throw in a ‘free’ 50″ plasma TV.

Large Plasma TV’s are, of course, the most energy inefficient form of watching telly known to man. Apart from maybe hiring your own multiplex cinema every evening.

Let’s do some sums:

Having a quick look on energyrating.gov.au tells me that a typical 50 inch plasma with typical usage patterns will suck about 850kWh of electricity per year.

So that’s 2.3kWh of electricity per day.

A good quality 1.5kW solar system in Adelaide will produce approximately 6.6kWh per day.

So that ‘free’ plasma is going to reduce the output of your $10,000 (gross of all rebates) solar power system by 35%.

And if you were planning on exporting that 2.3kWh of electricity to take advantage of SA’s generous net Feed In Tariff then you would be losing $503 per year thanks to the ‘free’ plasma TV.

What a great offer!

P.S. The number one sign of a great solar panel installer is that they actually care about your current and future electricity usage so that you will get the maximum benefit and maximum payback from your shiny new solar panels. If the installer doesn’t care about energy efficiency, quickly move on to someone that does.

Daily Telegraph gets on its high horse about Solar Power and Electricity prices

October 10, 2010 2017-05-03T14:00:16 by Leave a Comment

I’ve been in Sydney for a couple of days (including a really interesting tour of Silex Solar’s impressive Solar Panel factory at Olympic Park).

I picked up the Daily Telegraph in the hotel this morning to see the front page screaming about electricity prices.

According to the paper, the only person who can bring NSW electricity prices down is the Premier: Kristina Keneally – and the Telegraph is demanding that she does something about it – or else…

Now I’m no fan of  the mob of incompetent cronies and hollowmen that has made up the NSW government for the past few years, but electricity prices are high because of massive demand and limited supply. That demand is created by the NSW public building black roofed McMansion hotboxes with 10kW air-conditioning as standard and almost no insulation or window shading – never mind double glazing.

Let’s take some responsibility for our actions and accept that if we create massive demand for something (through being hopeless at implementing simple energy efficiency measures) we shouldn’t be surprised if the price goes up.

The Telegraph’s solution to all this is for the State Government to hand out hundreds of dollars a year to people with high bills and stop encouraging people to invest in solar power by scrapping NSW’s Solar Bonus (Gross Feed In Tariff).

So let me get this right: the journos at the Telegraph think that the solution to high electricity prices is to reward the people who use the most electricity, and stop rewarding those people who choose to generate their own?

I say: just leave the market to sort itself out. High electricity prices (combined with intelligent rebates for energy efficiency) will encourage more people to be more energy efficient, which will reduce the demand for electricity and increase the supply from solar power, which can only push electricity prices down.

And don’t forget that the majority of the increase in electricity prices is to fund the building of more wires and poles to cope with “peak demand” periods. These peak demand periods are basically when the sun is at its hottest in the afternoon and everyone’s air conditioners are running full throttle. Power output from residential solar panels peaks at exactly the same time, helping to reduce peak demand. And because the solar panels are on your roof and any power exported will be used locally, they don’t need pylons and hundreds of km of power cabling to get the power to the end user.

ACT announces improved Feed In Tariff

September 17, 2010 2016-05-31T14:53:42 by Leave a Comment

The ACT government made a welcome announcement about their, already generous, Feed In Tariff, last week.

The main points were:

The FIT now applies to “community owned” solar systems. That means that if your roof is shaded and you want to club together with others in the same position and install a system on the local RSL (for example) there is nothing to stop you getting the FIT and sharing the rewards.

Or if you live in units, you can get a shared system on the roof of the unit block.

The Feed In Tariff will be applicable for systems up to a whopping 30kW, so it becomes quite an interesting investment proposition in today’s volatile market. ( This solar calculator will crunch the numbers if you’re interested).

They also announced FITs for large scale solar. here are the details:

  • An overall scheme cap of 240 MW of generating capacity;
  • Large scale generation category for generators larger than 200 KW (category cap of 210 MW);
  • Medium scale generation category for generators between 30KW and 200kw (category cap of 15 MW); and,
  • Existing micro generation category (household rooftop) up to 30KW (category cap of 15 MW).

Some of the funding has come from the axing of plans to fund a $30 “Solar Facility” in ACT (whatever that was meant to be – probably was gonna be a bunch of public servants running around and racking up platinum frquent flyer accounts writing reports and attending conferences on how to reduce CO2 emissions – if my experience at CSIRO was anything to go by…)

In summary – great news from the land of the public servants – now we just need Julia Gillard to make all their legislation redundant by announcing a national FIT … we can but hope.

Solar Installer Reviews now live

September 11, 2010 2014-01-05T18:53:31 by 31 Comments

Because you asked for it – we’ve done it.

Over the last 4 years we’ve collected over 11,000 (and growing) reviews – mostly good, but a few bad and or ugly – of solar installers all over Australia, whether they are clients of ours or not.

My experience over the last few years is that most installers are honest, hardworking and passionate about doing the right thing by the customer and the environment. But there are always a few bad eggs in any fast growing industry. Now those guys have nowhere to hide. You gotta love this internet thingy!

You can now see these solar installer reviews online – just click the solar installer menu above, then use the search box when you get to the “solar installers” page.

If there are any installers you *really* want to see reviews for that aren’t there – let me know.

And if you would like any features adding to the review pages – let me know through the comments…

German magazine tests 10 solar panels

September 4, 2010 2014-01-05T18:53:50 by 3 Comments

In September 2006, respected solar power magazine, Photon International, bolted 10 different solar panel manufacturers panels to a test rig in Germany and measured the performance of those panels over 12 months.

The panels they tested were:

  • Photwatt
  • Solarworld
  • Shell Solar
  • BP Solar
  • Solar Fabrik
  • Isofoton
  • Kyocera
  • Sunways
  • Sanyo
  • Sharp

The results of the testing were that the difference in power produced across all the solar panel brands was 9.85%.

The results are shown here:

Solar Panel test

From Photon International Magazine September 2007

As you can see Photwatt panels came top.

Interestingly the Sanyo panels which many vendors claim are the “best of the best”, came second last. Apparently Sanyo’s excuse was that the magazine were supplied with defective panels, oh and the dog ate their homework too I imagine.

The well known brand “Sharp” came a surprising last place.

Of course this test was 3 years ago. I imagine that the losers of this test have upped their game in recent years. The latest issue of the magazine has some more recent results in it as soon as it arrives in the mail from sunny Germany, I’ll let you know the latest winners.

Wouldn’t it be great to put the top 10 most popular Australia panels through a similar test (including the many ‘own-brand’ panels). Let me know if you think that is a good idea in the comments. If I get enough interest I may organise such a test myself. Watch this space…

Is Global Warming a Hoax and Solar Power a waste of time?

August 27, 2010 2014-01-05T21:07:29 by Leave a Comment

Most of my websites are all about energy efficiency and also using technologies like solar power to get your electricity bills down.

Of course, a huge motivation to do this is that many people believe that CO2 emissions damage the environment though global warming.

Other people are motivated financially. Others just like the thought of taking responsibility for generating the power that their household uses.

Whatever your personal view on Global Warming, you can’t have failed to sense a growing scepticism about the issue recently.

A lot of folks are wondering whether the whole thing is just one big hoax by vested interests. For example: Scientists who want research dollars. Or Pollies who want an excuse to collect more tax dollars.

So what’s the truth? Is it a hoax, or if you don’t believe in mass conspiracies, are the majority of climate scientists simply getting brainwashed by the research dollars waved at them?

Well, anything is possible!

I certainly live my life by the adage, that if the government, says something is a given – then usually the opposite is true…

Example BS pedalled by the government:

• the US Banking System being safe as (sub prime) houses,
• the need to be protected by internet censorship filters
• first home owners grants make houses more affordable
• Canberra is a nice place to live and work ☺

My personal take is that, yes a lot of politicians do get very excited at the thought that they can tax us more and use Global Warming as an excuse,

And yes – some scientists have a very vested interest in GW being real, but… I’ve never really been one for conspiracy theories.

And the mind boggling size of the conspiracy you would need to subvert the thousands of scientists who have contributed to the peer-reviewed science is just mind boggling. Forget the moon landing being a fake – this would be on a whole new level.

The other thing that has convinced me of the reality of global warming is a Pommie journalist called George Monbiot.

If, like me you don’t have the time or patience to read through the science and decide for your self if it is sound, you could do worse than to read Monbiot’s opinion. ( a quick Google will find these articles)

He has read the science, formed a very objective opinion. And he is scared witless about what the future holds.

He now makes it his mission to question the arguments against GW head on. He recently went into verbal combat with one of the world’s leading global warming sceptics, Australian, Ian Plimer on Lateline.

Have a look at the video and see what you think– If nothing else it is a fascinating showdown:

Ian Plimer and George Monbiot Battle on Lateline

How to build a giant Solar Powered Oven

August 20, 2010 2014-01-05T21:07:29 by Leave a Comment

Does your house feell like a forced fan convection oven in summer?

Here’s how to build a highly efficient, giant solar powered oven.

Eight steps to making sure your oven gets as hot as possible in summer: powered by nothing other than the sun!

1. Erect a wooden frame about the size of an average house.

2. Build bricks around the outside of the frame. Bricks have a good thermal mass, which means that as the sun shines on them in the day, the bricks will store the heat and radiate it back into the oven long after the sun has gone down.

3. Fix a very low thermal mass material (like plasterboard) to the inside of the timber frame so that if any cool air gets in the oven (heaven forbid), the coolness won’t be stored in the inner walls.

4. Put lots of glass in the walls (avoid double glazing at all costs), especially the north facing one. Make sure these windows have minimal awnings.

5. Put black colorbond (ideally) or dark tiles on the top of the timber frame to maximize the heat absorbed by the ‘roof’ of the oven.

6. Add a fan that blows air down from the top of the oven. This way, as the hot air inside the oven rises, you can blow it back down to floor level to makes sure that anything on ground level gets suitably cooked through. To keep things simple, we’ll refer to this ventilation system as the ‘Ducted Air System’

7. If you are worried about cool air getting into the Ducted Air System, then simply add an insulated ceiling to create a roof space.  Ensure all the ducted air system’s pipes are kept inside this ferociously hot roofspace.  This will  minimize the chance of any air in the pipes actually getting cold.

8. If the meat in the oven needs a little more grilling, then add dozens of high powered halogen heaters liberally recessed into the ceiling. As well as producing enormous amounts of heat these little halogen bulbs will produce a small amount of light as an added bonus.

If your house was built like this and resembles an oven in summer,  the two most cost effective things you can probably do are:

a)   Fit mains or solar powered fans into the roof to remove the hot air from the roofspace. These will remove 7-10 times as much air as a passive ‘whirlybird’.

b)   Fit external awnings on all N, E and W facing windows.

If you do those and your cooling bills don’t halve, I’ll eat my cancer-council approved wide brimmed hat.

NSW Solar Bonus Scheme

January 13, 2010 2017-05-03T14:01:35 by 1 Comment

NSW gross feed in tariff

As the fireworks erupted from Sydney Harbour Bridge at 12:01am January 1 2010, the NSW Solar Bonus Scheme opened for business. It means that NSW solar panel owners will be able to collect 60c for every kWh produced for at least the next 7 years.

It will be available to panel buyers until all the installed generators under this Scheme  reach 50 MegaWatts.

Panel owners who are eligible are the small electricity consumers. They are those consuming up to 160 megawatt hours of electricity annually.

Generally, this includes typical households,schools, small businesses and most community organizations.

Under this scheme, people will be able to get Solar PV Systems and Wind Turbines up to 10 kiloWatts in size.

According to Energy Minister John Robertson, the industry is expecting to install around 33,000 new solar systems during the life of the program.

The government is banking on solar PV costs decreasing over the next few years. Many are expecting that within the next 3 to 7 years, solar energy’s unsubsidized cost to consumers will be near that of dirty fossil based generation.

But in the mean time, the NSW Gross Feed In Tariff is giving a head start to the NSW solar industry so they can tool up, scale up and bring costs down and ROI up for Solar PV buyers.

Let’s hope the Feds watch and learn!

Huge Subsidies (and waiting lists) for Solar Hot Water in QLD

November 30, 2009 2017-05-03T14:03:18 by 2 Comments

The Queensland Solar Hot Water program is delivering and installing $500 systems for eligible Queenslanders and $100 for pensioners. But as you might expect, there is the mother of all waiting lists.

To date more than 850 customers have been allocated to suppliers to conduct inspections and install new systems.

By the end of this week over 110 systems will have been installed in Brisbane and a further 200 have been contacted to arrange site inspections.

More than 43,000 Queenslanders have registered their interest to participate in this program with more than 10,000 completed applications received so far.”

NSW Feed In Tariff Surprise: It’s Gross (in a good way!)

November 10, 2009 2017-05-03T14:03:48 by 3 Comments

Yesterday the NSW Government surprised renewable energy fans by switching the new feed in tariff from a net to a gross tariff.

This means that owners of solar systems in NSW will now get 60c per kwh for all the electricity they generate.

Previously you were only going to get paid for the power exported to the grid (i.e not the power you used in your house)

This makes a huge difference to the economics of buying a solar power system in NSW.

Plugging the numbers into my solar calculator shows that a good quality 1.5kW system will pay for itself in just over 4 years.

In fact you’ll be getting around $120 per month of income from the outset. And the benefits will only go up as electricity prices rise.

Even if you take out a $7000 loan at 7% interest the system would be cash flow positive from the outset. See for yourself here.

That’s a better return, and much lower risk than most other investments these days.

Have a play with our solar calculators to see if it makes financial sense for you. Just put ‘Feed In Tariff %’ as 100% and ‘Feed In Tariff Price’ as 60c and the calculator will work out the payback and monthly savings.
