The Power Roof tracking system is a new concept
in solar energy that integrates the best energy efficient technologies
with the most advanced solar thermal energy systems known today.
The Power Roof 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 one assembly serves so many functions, construction
costs are much lower than if they were 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.
Because
of the extremely high temperatures collected by the system, there
is also an opportunity for cascading heat flows from one process
to another, capturing this energy that is typically wasted. By capturing
this energy the overall efficiency is enhanced to levels two or
three times those realized by photovoltaics.
