SolarGenix Energy (formerly Duke Solar) and Innovative Design have combined advanced solar technology and sustainable architecture to produce a unique building-integrated solar thermal solution – the Power Roof™. These systems are now being implemented in offices and industrial buildings throughout the world. | |||||

PowerRoof™ system - Testing site, Raleigh, NC |
With the highest solar thermal collection efficiencies in the world, the building integrated Power Roof™ systems not only provide for winter space heating and domestic hot water needs, but also produce electricity and drive an absorption cooling equipment. The Power Roof™’s fully integrated approach also allows the system to provide daylighting, serve as a radiant and thermal barrier, eliminate the need for additional roof structure, and create a waterproof roof membrane. | |||||

Innovative Design and SolarGenix’s Building Division have created the “smart roof”, for the 21st century, a sustainable building solution that provides building owners with more than a watertight enclosure, and much more than a solar energy system. The roof-integrated approach of the Power Roof™ has many advantages. Costs, materials, and time are reduced because components that are typically incorporated into solar systems serve multiple purposes. The collector structure and the natural daylighting have all been combined into a simple innovated system. And integrating the solar system into the roof eliminates the need for additional land and improves the efficiency of the system. This approach also provides the opportunity to use the roof design for natural daylighting and to serve as a radiant barrier.

The
Power Roof™ tracking system is a high-temperature solar energy collector
with a fixed reflector and a receiver that tracks the sun during the day.
It incorporates a natural daylighting system, a radiant barrier, an insulating
system, an optional means to capture passive solar heat in the winter, an
infiltration barrier, the building roof structure, and a guaranteed waterproof
roofing system all in one. Because so many functions are served by one assembly,
construction costs are much lower than multiple products built separately. Because of the system's enhanced solar energy concentrating power, it can reach temperatures up to 750 degrees F. This energy can be used for industrial process heat, absorption cooling, desalination and water purification, as well as for secondary space heating and domestic hot water. Where needed, it can also be converted to electricity for individual facility requirements or sold to utility companies during times of peak electrical demand. |

| Power Roof™Fixed Array | ||||||

This
system uses a roof-integrated collector that employs non-imaging optics
to produce the most efficient solar collector tube in the world. Arrays
of these collectors are connected together to capture enough energy to power
double-effect absorption cooling equipment for commercial and industrial
buildings – the only fixed solar system in the world to have this
high-temperature capability. While cooling is the optimal use of this system,
it also produces space heating in the winter, heats domestic water, and
can produce electricity for office or small industrial buildings. When implemented
into a typical sawtooth roof, the system also allows for daylighting. This fixed array system can produce solar-heated fluids up to 350 degrees F, and is capable of reliably converting the thermal energy to electricity, absorption cooling and industrial process steam. Additionally, by capturing the waste heat from these processes, the overall system's efficiency can be greatly magnified by also fulfilling desalination, space heating, and hot water needs. |
