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.
