Can Queensland be a solar energy powerhouse under the Newman government?

Tim Flannery reckons Campbell Newman may be a closet solar fan. Unlikely?

The Climate Commission’s recent report pointing to Queensland as a potential solar energy powerhouse has caused a bit of a traditional brouhaha in the opinion pages of the press and online journals.

 

Nothing like a bit of biffo as we say here at SQ headquarters (particularly in the wake of a grand final weekend) so we thought we’d examine the argument, squeeze out more on a favourite theme  (government inaction on renewables) and have a bit of a rant ourselves. [Read more…]

Solar Panel Tilt Frames: Are they worth it?

July 15, 2012 2024-06-05T11:52:57 by 61 Comments
tilt frames for solar panels

Tilt frames maximise energy yield, at a price.

Here is (another!) really common question that I get:

“I’ve got 3 quotes for solar: The first company says my roof is at the wrong pitch and wants to charge me hundreds of dollars extra to put my solar panels on tilt frames to optimize the amount of electricity I get. The second mob say it is fine to just put the panels flush on my roof and the third guy says that, yes my roof isn’t at the perfect pitch, but the best solution is to mount them flush to the roof and simply add an extra solar panel to make up for any reduced power output.

Now I’m really confused! Help!”

The problem here is that there are 2 extremes of solar installer in my experience: [Read more…]

Samil Power Inverters: The Hyundai of the Solar Industry?

Solar Infographic : If Inverters were Cars…

The current edition of industry bible “Photon Magazine” (June 2012 issue) has a glowing review of the Chinese made Samil Power Solar Lake 15kW inverter.

A couple of years ago if you were investing in a 15kW solar system your default choice would have been a European inverter – think SMA, Aurora or Delta. It would have been a very brave engineer that specced a Chinese inverter on such a big system!

However in a few short years the Chinese have learned from any mistakes made and are producing some world class solar inverter hardware.

Solar Panel Orientation: Is West the new North?

May 23, 2012 2019-12-10T14:19:19 by 53 Comments

The following is a very common question that comes in to SQ HQ.

“My roofline is North/South, so my largest roof areas face either East or West. I have been told that North Facing is ideal, but I  have a tiny North facing roof! Can I put some solar panels on the East or West Facing roof (or both) ?”

Short Answer: Stick some (perhaps all) on the West!

Longer Answer: In terms of the amount of power produced, facing your panels East will produce exactly the same amount of power as facing them West.  In either case you’ll generally take a 10-15% power hit compared to having them facing the ideal direction (North).

Compass

Is North always the best direction for solar panels?

So why do I say “probably West” as the short answer to the question?

Well, the reason I err on the West facing roof is because that part of your roof will get the sun later in the day. An East Facing solar array will generally produce its peak power at 10-11am. A West Facing array will produce its peak at closer to 2pm.

Most people use more energy later in the day. And most people want to use as much of their solar energy as possible, without exporting it. Why? Because at the time of writing most Feed In Tariffs give you less per kWh if you export the electricity than you pay for imported electricity. So most people will pay off their solar system quicker if they minimise exports.

PV world record tumbles as UNSW looks to wrap up series

Suntech and UNSW logos

Suntech and The UNSW team up and kick solar ass!

Aussies love awards and stellar achievements. Particularly when we’re on the receiving end. Best and fairest, most valuable player, player of the series, best supporting actor, Treasurer of the Year (hang on!) and so the list goes on. Our collective chests burst with pride when we hear of the achievements and world records of our sports and silver screen idols and this gives us a sense of playing on the world stage with the big boys/girls.

Carbon Tax and Government Support – the Other Side of the Coin

September 25, 2011 2017-10-25T10:36:10 by Leave a Comment

Last week we examined the point of view of academic Mark Diesendorf who stated that the much villified carbon tax will probably be insufficient to encourage renewable energy investment in Australia. This week we look at the opposing view and find that overseas renewable energy companies are indeed putting their hands in their pockets to fund renewable energy schemes in Australia, particularly those looking at exploiting our abundant sun.

These companies are looking at taking advantage of the positive renewable funding climate in our country, support which is expected to be funded through revenue supplied by the contentious carbon tax. [Read more…]

Will the Carbon Tax Boost Large-Scale Solar Projects?

September 15, 2011 2018-05-09T11:24:58 by 1 Comment

The debate over whether or not a carbon tax will be effective has split families, pitched neighbour against neighbour, divided loyalties and torn our nation asunder.

Well not exactly, but a real blockbusting start to this week’s column you have to admit!

On a serious note, the question many SolarQuotes readers would like answered about the carbon tax goes something like the following. Will the carbon tax (assuming the legislation is passed) bring any benefit to the solar power industry in Australia? [Read more…]

Is WA’s Support of Solar Utilities at the Expense of Domestic Projects?

September 1, 2011 2017-10-25T10:38:00 by 1 Comment

When we think of Western Australia we generally consider mining booms, expanded gas projects, black swans and the West Coast Eagles football team (and Dennis Lillee and Rod Marsh for those of us with age on our side).

But as an Australian leader in solar technology? After a recent government decision to close down its solar feed in tariff scheme because of its (wait for it) popularity, the expected answer would generally be no. However recent developments in the West have shown government-owned corporations partnering up with the private sector to lead the state down the path of potentially being one of the country’s leading exponents of renewable energy.

Chinese Solar Company Says Improved Solar Efficiency On The Way (based on Aussie Technology!)

April 7, 2009 2017-05-03T14:37:44 by 2 Comments

The largest producer of solar panels in the world, Suntech Power Holdings, has recently reported more information regarding its latest Pluto technology. This new technology has made substantial progress in improving the conversion efficiencies of solar cell technology

Although there have been a number of improvements in technology in the industry overall, none of the others are yet ready for commercial distribution. Although the Fraunhofer Institute achieved a solar cell efficiency of over forty percent, it, also, is far from ready for mass production.

Already in the process of mass production, Suntech’s Pluto technology has employed solar panels with efficiencies of 19% in monocrystalline technology and 17% in polycrystalline panels. Other current technology currently has efficiencies of 18% and 14% respectively.

Aussie Technology Promises To Make Solar Panels More Efficient

March 27, 2009 2017-05-03T14:43:09 by Leave a Comment

New solar energy technology has been demonstrated at the University of New South Wales. Developed in Sydney, the first ever silicon solar cell production will commence at the university with the help of funds granted from the Federal Government.

This technology is expected to have a positive impact on the local industry and help to renew it after the closure of the largest factory producing solar panels in the area (BP Solar).

With most of the current technology, there is the problem of shorter wavelengths which are reflected back by the phosphate ducting inside the panel. The new technology helps to optimise these ducts, allowing the panel to absorb more light while keeping the costs of production the same. [Read more…]
