1. 1. Experimental Testing of Solar Photovoltaic/Thermal Collectors for Low Temperature Heat Pump Integration

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Jaakko Eskola; [2023]
   Keywords : Solar photovoltaic thermal; PVT; heat pump; thermal performance; ISO 9806:2017; Solhybrid; PVT; värmepump; termisk prestanda; ISO 9806:2017;

   Abstract : A hybrid photovoltaic/thermal (PVT) collector enables simultaneous electricity and heat production from a single solar module. Integrating PVT collectors with a ground source heat pump (GSHP) improves the seasonal performance of the heating system and prevents from temperature degradation of the ground. READ MORE
