Roof-Mounted Solar Tracker in Maryland

We’ve mentioned solar-tracking but the systems are usually pictured on a pole in a big grassy yard.  This is a Dual-Panel Tracker by Maryland-based Advanced Technology & Research Corp. (ATR) on the roof of a row house in Federal Hill in Baltimore.  The install consists of two panels, 235-watts each, on a sun tracking mount with a GPS-controlled drive unit that follows the sun to yield about 30% more than fixed panels.

Interview: LiFe Powered by the Sun

Carolyn and Kyle Cave, both university professors in Hadley, Massachusetts, built this super-insulated home to minimize energy consumption.  Then they dropped a 20kW solar PV array on the roof and now use energy from the sun to generate a surplus that also powers this tiny little Wheego LiFe electric vehicle.  I was able to ask Carolyn Cave a few questions about their solar-powered situation, and this is a portion of that response:

CertainTeed Intros New Apollo Solar Roof

During Greenbuild in Toronto, CertainTeed Corporation introduced a new solar photovoltaic system called the Apollo Solar Roofing System.  Apollo skips the rack and mount for a seamless profile that integrates with standard roof shingles.  Each 12-pound module has 14 high-efficiency, polycrystalline silicon solar cells that soak up the sun and convert it to energy to power the underlying home.
