Interest in combined solar heat and power accelerating by Justin Blows

There are now several players who are working to capture the heat generated when sunlight falls on photovoltaic modules and then putting it to good use.

Chromasun is one such player patenting in this area.   An international patent application by Chromasun discloses concentrating solar light using compact Fresnel reflector onto a photovoltaic strip, behind which is a thermal solar receiver in which a liquid that receives the heat flows.

Chromosun’s web site suggests that this technology could be deployed on the roof tops of buildings, presumably including dwellings.

Mitsubishi, who is a big player in wind turbines, is developing a rooftop solar unit that they claim cam supply 65% of a household’s energy needs. According to this report, the product generates solar hot air and electricity. Air flow between the PV panel and a standard roof captures the heat. The air flow recovers heat from the solar panel side. By recovering the heat, it can then be used for household heating and hot water supply. Testing of a three kilowatt unit apparently verified that 65 percent of energy consumption in each household could be replaced by solar energy.

Solar industry roundtable broadcast by Griffith Hack

In a broadcast this week on Boardroom Radio Australia (, Dr Justin Blows led a roundtable discussion on the topic of solar energy with the following contributors: Richard Caldwell (Chairman, Dyesol), John Grimes (CEO, ANZ Solar Energy Society), Alistair Sproul (Associate Professor UNSW School of Photovoltaic & Renewable Energy Engineering) and John Dyson (Investment Principal, Starfish Ventures). 

The interactive broadcast allowed listeners to submit questions as it was in progress, directing the focus of the discussion.

The broadcast  explores the future of solar power as a viable renewable energy, and the medium to longer term commercial opportunities that exist in this area.  It was noted that Australia is currently behind other countries such as the US, China and Germany, in solar power usage and development.  Archaic government policies in the renewable technologies area, when compared with other countries, was one reason given for this.

The full broadcast is approximately 25 minutes long, click here to listen.

Australian Solar Innovation: Losing Our Place In The Sun by Griffith Hack

Griffith Hack is pleased to announce the launch of the report ‘Australian solar innovation: losing our place in the sun’.

We may be one of the world’s sunniest places, but analysis of solar energy patents filed during the past five years, highlight that Australia is at risk of missing out on the new gold rush involving clean and sustainable technologies.

Leading economists have already noted that clean energy technology has the potential to create wealth on the same scale as the introduction of the railways, electricity, cars and, more recently, IT.

The report ‘Australian Solar Innovation – Losing Our Place In The Sun’ finds that we are being left behind, in the race to properly protect the ideas that will drive economic benefits into the future.  

“Australia’s weak performance in the utilisation of solar power is at odds with the quality of our innovators,” the report notes. “We have produced the world’s first solar billionaire in Dr Zhengrong Shi  (who founded the Nasdaq-list Suntech), while Dr David Mills, formerly of the University of Sydney, founded the Californian company Ausra which is helping to lead solar innovation in the United States”
