Improving the accuracy of energy yield calculations of tandem solar cell‐based CPV‐modules

Energy yield calculations for CPV modules that use tandem solar cell technology have been performed and analysed in this work. Two BSQ D280 were used as specimen: one located Freiburg, Germany, Greater Noida, India. The current–voltage curves of both measured several months together with the prevailing ambient conditions. energy respective measurement periods calculated using software PVsyst. It has found modelled PVsyst a good agreement but deviates by 10% from Noida. reason is most likely high aerosol content Noida thus non-appropriate consideration spectral irradiance impact PVsyst, which uses air mass DNI only atmospherical parameters. accuracy calculation strongly improved work SMR corrected values input calculation. In manner, variation on (C)PV module power output can be considered deviation could reduced to below 1%.
