Heliotube is a new sun tracking form of solar panel due for release this year by Solient Energy. The Helio tude uses 88% less PV cells than a traditional PV solar panel and replaces them with more cost effective optics that concentrate the sun onto smaller PV cells. The obvious upside of this is that the cost of solar panels will come down.
Further maximising the panels potential, it has a built in tracking system that rotates the collectors to follow the sun, as apposed to the majority of tracking systems that rotate the entire panel to track the sun.
On top of all this, the panels look good and are a vast improvement on the aesthetics of the majority on the market.
They are due for release in commercial application this year, with residential due in 2008.
