As solar panel manufacturers try to harvest more of the sun’s energy for less, they face increasingly diminishing returns. At roughly $1 per watt, the cost of solar modules now represents less than a third of the total cost of commercial solar installations. To cut the total cost of solar power—currently $3.00 to $3.50 per watt—bigger gains will have to come from improvements in the power electronics, wiring, and mounting systems required for solar installations.
The CHIP House – which stands for “Compact Hyper-Insulated Prototype” – was started with the goal of creating a net-zero energy home (i.e. one that requires no external energy source), and it looks like the designers exceeded that target. The house actually generates three times as much energy as it uses thanks to solar panels and a host of energy saving measures.
Environmentally friendly homes can reduce inhabitants’ carbon footprints, save resources and lead the way for others to live the same way. Most of us, however, have been living in homes that are pretty standard, in that they don’t help us reduce our carbon footprints. The US Department of Energy has been trying to further green living in terms of homes and has been organizing the Solar Decathlon for a while now. The international competition is a biennial event that challenges 20 college teams to come up with conceptual homes that utilize solar energy. The teams get to work on site, detailing their prefabricated houses for 10 days in a bid to take home the Solar Decathlon title. 2012’s competition is set to begin and we’re eager to see who wins the coveted prize.
Italy and France have joined forces to create the “Astonyshine” 100 percent solar home concept as part of the 2012 Solar Decathlon Europe. The international competition is open to universities from around the globe and promotes research into the development of efficient housing. Astonyshine is a modern reinterpretation of the classic Mediterranean villa, and is the result of the combined efforts from Polytechnic of Bari (Italy), University of Ferrara (Italy), Ecole Nationale Superieure d’Architecture Paris-Malaquais (France) and Ecole des Ponts ParisTech (France).
