As regular readers will know, we cover more than our fair share of breakthroughs promising next-generation super-efficient solar cells. Everything from growing photovoltaic crystals, applying special coatings or using carbon nanotubes teases us with cheaper, more efficient solar energy – eventually. In this latest news, scientists are using current technology in a new type of concentrating array which they say is four times more efficient and three times cheaper than current solar cells.

The technology was originally developed at the Royal Melbourne Institute of Technology (RMIT) and will be commercially produced by a spinoff company called Technique Solar. Each solar module consists of nine “troughs” that feature a concentrating acrylic lens and reflective walls to focus the sun’s rays onto a strip of photovoltaic (PV) cells, which enables the number of PV cells to be cut by 75 percent. The PV cells are used to generate electricity, while a heat exchanger located under them is used to generate heat for circulating water and storage tanks for a hot water system. Additionally, to maximize the sun’s rays the array has a motor drive mechanism with tracking sensor to follow the sun.

The company says its Concentrated Universal Energy Solar System (CUESS) makes it possible to deliver solar energy more economically and more efficiently than other current forms of solar energy generation. Each 3.5 square meter array apparently produces a total of around 2.1-kW of power, while a standard PV panel would need to be around 12-14 square meters to produce around the same amount. Technique Solar says its panels can supply heat load (hot water) and electrical energy at one quarter of the energy costs of conventional solar energy systems.

  1. Solar Energy is one of the best ways to get clean energy . Today the efficieny of solar power is a bit low but with advances in technology, solar cells will become more and more efficient in harnessing the energy of the sun.

  2. solar energy is by far the best method of clean and green energy..

    i think that in the future it wil get cheaper and cheaper and the technologie will get much better…

  3. I built my own solar panels which saved me thousands of dollars and it was no way near has hard as you may think. It is deffinatley an option for people who do not want to pay the hefty price tags which most solar panel manufacturers charge.
