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…]

Interview with Paul O’Reilly of the Rainbow Power Company

Rainbow Power Company – one of Australia’s oldest solar companies

In this, the first in what we hope will be a number of interviews with solar opinion leaders, business people and experts in the solar industry we chat with Paul O’Reilly, director of the Nimbin-based Rainbow Power Company. Sit back and enjoy as Paul talks feed-in tariffs, the almost constant boom and bust cycles in the Australian solar industry and his optimism for the future.

The solar industry must have changed a lot since Rainbow Power Company first set up? Do you think this has been for better or worse?

What is solar tower technology?

News that the Perth-based renewable energy company Hyperion Energy is planning to build a solar tower in mid-west Western Australia sent your correspondent scurrying to the research files this week.

According to the company website, Hyperion have purchased a 127,000 hectare site near the town of Tuckanarra. The site is near mines and an airport and is judged to have a low risk of natural disasters such as earthquakes or cyclones. Chiefly though, the main advantage of the site for the location of a solar tower is the “horizon solar radiation of 2300MJ/m2” (read huge), according to the company.

The theory behind the solar tower technology sounds simple enough. A flat, large expanse of a greenhouse-like material is spread around the base of a tall tower. When the sun heats the air under the material it rises (remember your science?) and as such has only one place where it can go: the central solar tower (see diagram). The hot air is forced through the narrow space of the tower where it causes a wind which turns a number of turbines inside the tower.

Hyperion points to three key advantages of solar tower technology over other forms of tapping the sun’s energy.

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

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

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.

Cambridge Uni Boffins Hoping To Win Aussie Solar Powered Car Race

Cambridge University students, in the UK predict their new solar powered car will be capable of cruising at 60mph, and intend to enter the up and coming World Solar Challenge.

Equipped with a 6m2 ‘skin’ of silicon cells, the journey, from Darwin, will take the car, AKA ‘Bethany’, across Australia’s arduous outback, over three thousand kilometres, to Adelaide. Bethany’s outer skin covers a highly efficient electric car, one its creators say could be a prototype for future ‘green transport’.

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

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.

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

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.
