As Rooftop Temps Rise, Power Decreases in Crystalline Silicon Solar Modules

The performance of crystalline silicon - widely considered a reliable solar module construction - declines amid rising temperatures of rooftop modules, according to studies performed by TÜV Rheinland PTL, LLC, a member of the world's largest solar and photovoltaic testing network.

The Zero-Emissions Dice Shaped House

The Dice House looks like part of a Monopoly set, but the design has real-world ambitions. The 30-by-30-by-30-foot concept home, designed by the British architecture firm Sybarite, improves on standard building tech to erase its carbon footprint. The centerpiece is a photovoltaic umbrella dome that collects roughly 90 percent of the house’s energy needs. Made of a common plastic, the pillowy dome traps heat like a greenhouse. That hot air warms water in a tank tucked under the roof, turning out a daily average of 80 bath-ready gallons, even on the darkest days of December. At the umbrella’s apex, a generator-equipped turbine produces electricity and, in chilly months, drives heat into the house. Photovoltaic cells studding the 484-square-foot dome floor create additional electricity. Generating an estimated average of 33 kilowatt-hours per day, the house can power itself and charge a Tesla Roadster.

Solar plane lands after completing 24-hour flight

PAYERNE, Switzerland – An experimental solar-powered plane completed its first 24-hour test flight successfully Thursday, proving that the aircraft can collect enough energy from the sun during the day to stay aloft all night. The test brings the Swiss-led project one step closer to its goal of circling the globe using only energy from the sun. Pilot Andre Borschberg eased the Solar Impulse out of the clear blue morning sky onto the runway at Payerne airfield about 30 miles (50 kilometers) southwest of the Swiss capital Bern at exactly 9 a.m. (0700 GMT; 3 a.m. EDT). Helpers rushed to stabilize the pioneering plane as it touched down, ensuring that its massive 207-foot (63-meter) wingspan didn't scrape the ground and topple the craft.

Solar plane cruises to historic flight

Confidence soared among the crew of an experimental solar-powered aircraft on Wednesday as it cruised above Switzerland in a historic bid to fly around the clock and prove the value of solar energy. The Swiss pilot's take-off run took barely 90 meters, testimony to the light weight and giant airliner-size wingspan of the single seater craft , which relies totally on 12,000 solar cells and nearly half a tonne of batteries.
