Solar Decathlon (2)


If you are in favor of renewable/CLEAN energy, please sign the petition page showing support for FIT/CLEAN Program at Thank you.

I am happy to report that the petition bug issue has been resolved.   I replaced those extra petition pages by link to just one page at the beginning of each post.  Apparently this petition plugin can only handle one page of petition. When the same petition page is being placed on multiple pages of the same web site, it is paralyzed….perhaps it does  not want to be overworked…chuckle….perhaps it is teaching us how not to be overlooked ?!

As I’ve promised you all, more innovative designs will surface during this series of presentation of Solar Decathlon.  I will start by showing you the winning design/team of Solar Decathlon 2009, the Team Germany.  As it turned out Team Germany had won twice, both in 2007 and 2009. One unique feature of winner of 2009’s design is its maximal use/coverage of the surface area (the house is practically completely covered by solar panels). These solar panels also function as shades during day time and change the angle of tilt throughout the day to maximize absorption of insolation (recall our discussion in March 20 and March 28 posts at Sun Is The Future on Insolation?).   The amount of energy gained by this house/design is able to support the energy use of three houses.  Since the additional energy gained can be sold back to the power grid in Germany (Germany is a strong proponent of the Feed-In-Tariff), the initial start up cost of this solar system can be quickly recouped.  The cooperative and optimistic atmosphere at Solar Decathlon is palpable.  Perhaps you’d like to keep in mind that the next Solar Decathlon event is scheduled to take place at the National Mall’s West Potomac Park from September 23 to October 2, 2011. It will be open to the public and free of charge, weekdays: 10:00 A.M.-2:00 P.M., weekends: 10:00A.M.-5:30 P.M.  Come and take a look to get some ideas for your future homes.  Now take a look at this video clip of the winning design of Solar Decathlon 2009:
