Low-concentrating water-cooled PV-thermal hybrid systems for high latitudes

Abstract

This paper treats the design and evaluation of low-concentrating, water-cooled photovoltaic-thermal hybrid systems with stationary parabolic reflectors for groundbased applications or facade-integration of photovoltaics at high latitudes. The use of photovoltaic-thermal hybrid string modules in combination with cheap aluminum reflectors has a potential to significantly increase power production from a given solar cell area and reduce the cost of photovoltaic electricity.
