It must be really depressing being a solar nark these days. With the increased popularity of solar power throughout Australia and the world, and regular announcements of improvements in technology, better storage capacity and cheaper prices, solar power is going through the roof (or on the roof). The more the narks whine about what they see as the limited capacity of solar, the more breakthroughs in technology occur to push back the possibilities of clean, solar, renewable energy future for our world.

Poly vs. Monocrystalline Solar Panels – Let’s put this argument to bed!

October 22, 2012 by 3 Comments

One steaming pile of Solar BS that you hear all the time from worst sales people in this industry – who will feed you any line to get a sale – is that polycrystalline panels are better than monocrystalline solar panels, or vice versa.

In this video I finally get off my chest why you should avoid anyone spouting such drivel:

Transcript is here if you don’t like listening to angry, sweary solar geeks: [Read more...]

Spinach-powered solar? Yet more benefits from eating your greens

October 15, 2012 by Leave a Comment

Spinach doesn’t only make Popeye kick ass – it might help make dirt cheap solar panels too.

We cover quite a bit in this column in our quest to bring you (the reader) up to speed on the latest in solar policy, news and development. From solar cars, to government policy (or lack of) to the latest solar technology to hit our shores. But we’ve yet to talk vegetables, their obvious benefits and how this relates to solar power. This week we change all that. [Read more...]

Turbo Boost for Solar?

Some major news on a local technological breakthrough for solar cells this week folks. This, as always, gives your columnist the  opportunity for some more shameless cheerleading on behalf of Australian solar watchers, in the increasing wasteland of government support for domestic solar systems.

(For help, see Finn’s latest article on how to future proof your PV system from perfidious state and federal governments.)

To begin with the Mexican wave (or Sydney University wave to be more precise) part of the article. An April 18 press release from the university has stated that Associate Professor Tim Schmidt, from the university’s School of Chemistry, has partnered with colleagues from the [Read more...]

Twin creeks technologies are claiming a cost reduction breakthrough for solar PV

Last week’s column brought you the latest, world-record-breaking achievements of the University of NSW. This week, just to balance the books a little, we thought we’d bring you news of the latest incredible overseas advance in PV cells from overseas — just to prove that solar research is pushing back the boundaries the world over.

The name of the firm is Twin Creeks, which may or may not be a nod to the superb David Lynch-produced TV series of the early nineties (or am I showing my age here?), and the breakthrough is that photovoltaic cells are created using a hydrogen ion particle accelerator. [Read more...]

AC Solar Panels (microinverters) : The #1 Solar Trend to watch for in 2012?

January 10, 2012 by 11 Comments

Will 2012 be the year of the AC Solar Panel?

Before answering that question I should probably explain exactly what an AC Solar Panel is…

An AC Solar Panel converts sunlight to AC electricity at the solar panel.

 

What is an AC Solar Panel?

The short answer is: An AC Solar Panel is a solar panel that takes sunlight in and spits AC (Alternating Current) electricity out. This compares to a “conventional” DC Solar Panel which takes sunlight in and spits DC (Direct Current) electricity out.

AC Electricity is the type of electricity you need to power the appliances in your home. DC panels need a Solar Inverter to convert the DC electricity to AC. The big advantage of AC panels is that there is no need for an inverter to do that conversion, so you have a really simple design, a simpler installation, and adding extra panels becomes almost plug and play.

The Problems With Thin Film Solar Panels

If you are looking to buy a solar power system and have done any kind of research on the web, then you have probably  come across lots of people  arguing over the pros and cons of Thin Film Solar Panels compared to the more common monocrystalline or polycrystalline solar panels. In a nutshell, there are 3 major types of solar panel technology on the market:

  • MonoCrystalline,
  • PolyCrystalline
  • Thin-Film

It seems a lot of people are firmly in either the “Crystalline” or “Thin-Film” camp. And when discussing which panel is best, they can easily lose their objectivity with arguments along the lines of “Thin Film is the only way to go” or “Mono Crystalline and Poly Crystalline are junk!”.

Australian Researchers Break World Record for Solar Panel Efficiency

July 9, 2011 by 1 Comment

By Rich Bowden

Now this is the sort of news your SolarQuotes.com.au correspondent likes to deliver. After weeks of wading through government reversals on solar feed-in tariffs, reporting on the various sniping at the edges of the solar industry and talking about savage cuts from state and federal governments affecting the Australian renewables sector, here comes a really positive development.

Suntech and Aussie Uni Team Up to Make Dirt Cheap Solar Cells

April 10, 2009 by 1 Comment

Victoria’s Swinburne University of Technology in Australia will be developing the most efficient, and inexpensive solar cells ever made. Along with Suntech Power Holdings Co, the biggest manufacturer of solar cells in the world. Together, they plan to invest a total of three million Australian dollars into the project and proposals have already been made to the Victorian Government with regards to extra funding.
