Abstract:
A photovoltaic/thermal (PVT) panel is a combination of photovoltaiccells with a
solar thermal collector, generating solar electricity and solar heat
simultaneously. PVT panels generate more solar energy per unit surface
area than a combination of separate PV panels and solar thermal collectors,
and share the aesthetic advantage of PV. After several years of research,
PVT panels have been developed into a product that is now ready for
market
introduction. One of the most promising system concepts, consisting
of 25 m2 of PVT panels and a ground coupled heat pump, has been simulated
in TRNSYS, and has been found to be able to fully cover both the building
related electricity and heat consumption, while keeping the long-term
average ground temperature constant. The cost and payback time of such
a system have been determined; it has been found that the payback time
of this system is approximately
two-thirds of the payback time of an identical system but with 21 m2
of PV panels and 4 m2 of solar thermal collectors. Finally, by looking
at the expected growth in the PV and solar thermal collector market,
the market potential for for PVT panels has been found to be very large.
