SolTech Sigma - SolTech Energy. The roof tiles we lay are made from glass instead of concrete or brick. These tiles are designed to work as both a high quality and durable roof tile, and to allow in as much light as possible. Solar ray capturing devices are located under the tiles and connected to the existing heating or hot water system. Heat enters your existing heating system via an accumulator tank.
The Behar Greenhouse is a model of passive solar sustainability. The frame is made of locally milled Black Locust timber. The in-bed thermal air exchange system and expandable end wall allow for tight control of temperature. The growing tables are suspended from overhead tracks that allow for more efficient use of space and the base vents give access into the cold frame along the base of the south wall to harden off young plants.
This North Carolina home gets most of its space heating from the passive solar design, but the solar thermal system (top of roof) supplies both domestic hot water and a secondary radiant floor heating system. | Photo courtesy of Jim Schmid Photography.
Heat Your Home w/ Solar Hot Water - This is close to our plan. The only difference is we plan on being able to flush the system with cold water as our floors will be cement and we can cool our floors also. :)
