The Heliotrope is the world’s first energy positive solar home, generating five times the amount of energy it consumes. Built in Germany, the Heliotrope rotates with the sun, taking full advantage of the sun’s rays with its roof-mounted array, solar thermal pipes and triple-pane windows.
A new report out from the Department of Energy’s National Renewable Energy Laboratory (NREL) looks into what solar policies at the state level are most effective at supporting solar PV installations.
What if your blinds could double as solar panels? This conceptual design by Vincent Gerkens would capture and store the sun’s energy during the day to illuminate the interior of your house at night.
The U.S. now has 142,698 employees working in the solar sector—up nearly 20 percent from the year before. That’s according to The Solar Foundation’s (TSF’s) fourth annual National Solar Jobs Census. Overall the growth rate eclipsed that of the national employment growth rate by about 10 times.
Colorado-based community solar developer Clean Energy Collective (CEC) will enter the Massachusetts market, making it possible for more people to go solar than ever before.
CEC will construct community solar gardens, enabling homeowners and businesses to harvest the benefits of solar—even if they can’t put it on their roof or in their yard—by purchasing a part of the garden’s panels and then using the power produced to offset some or all of their electric bill.
This solar-powered houseboat, the Bauhaus Barge, doesn’t use a drop of fuel. The innovation built by Jurgen Huber utilizes solar panels (1.64 peak kW output), extensive insulation, an efficient lynch motor, a skylight and additional windows to let the sunlight in, complemented with a fully-glazed door to keep heat from escaping.
Under-floor heating is also included, and combined with a 1930s stove to keep the boat warm during winter months.
