Abstract/Summary:


In this work, seven residential solar photovoltaic systems are evaluated for their technical performance under a full year’s operation in Sweden, at latitude 57.72. The system technologies are selected to reflect available products on the Swedish market and include three building attached (BAPV) and five building-integrated (BIPV) systems. The evaluation is done for the performance ratio (PR) and temperature corrected PR, and the results highlight the seasonal variation and effect from the modules' temperature dependency. The annual losses due to operation at elevated temperature are also quantified for each system, using a temperature-compensated power output, and the results show that the losses are 1-3.2% on the measured yield, depending on the PV technology and extent of roof integration (BIPV or BAPV).
