Comparison of PV Evaluation Programs Based on the Long-Term PV-Measurement Campaign of the Berne University of Applied Sciences

27th European Photovoltaic Solar Energy Conference and Exhibition; 4158-4160
Based on these data of the PV long term measurement campaign of the Berne University of Applied Sciences (BUAS) in Burgdorf (Switzerland) we compared seven PV calculation programs with two different studies. We used different sites on different climatic situations to evaluate the accuracy of the programs. The Berne University of Applied Sciences in the town of Burgdorf near Berne in Switzerland is measuring PV-installations in a long term test campaign since more than 20 years with high precision. Actually more than 70 installations are measured. For the study we used two installations in Burgdorf and the football stadium in Bern with more than 1,3 MWp as a typical sites for the Swiss Basin. Another installation was the 500 kWp site on the mountain range of the Jura. For the alpine climatic situation we used the PV installation on the Jungfraujoch on 3’454 m asli. In this first BSc-studyii done by Marc Hauser he used the PV program PVSyst from the University of Geneva to calculate the accuracy of the simulations against the result from the existing plants. In the second BSc-study done by Thomas Heinigeriii four freeware and 3 professional PV-simulation programs were compared with the results of the first study.
