Presented at: 19th European Photovoltaic Solar Energy Conference and Exhibition, Paris, France, 7-11 juni 2004.
Abstract:
Photovoltaic/Thermal(PVT) collectors in large solar thermal systems are the solution for
the scarce roof space on high rise buildings. A technical and economical
feasibility study showed that a system with PVT collectors generates
more sustainable energy per square meter in comparison with system of
PV modules and thermal collectors. A PVT collector system needs approximately
38% less roof space than a combined system of PV modules and thermal
collectors with the same efficiency yield. The financial data of PVT
collectors are still unreliable due to the lack of a learning curve.
The used data are based on the costs for a batch production in stead
of mass production. An indicative cost price for a PVT collector of ?720/m2 to become
competitive with a combined system could be distilled from the results.
