“…Undoubtedly, commercial PV simulation software packages are using combinations of these models and methodologies, each of which is scientifically sound; however, their accuracy as a complete software package against real-world data has not been assessed. Still, commercial software packages are being used as the basis of many scientific studies and papers [24][25][26][27][28], therefore their accuracy should be thoroughly examined against real-world data and for various conditions.…”

As the use of photovoltaics expands, with more and more commercial and residential users investing on solar energy systems around the globe, there is substantial demand for relatively simple, easy-to-use software packages, for the planning and performance estimation of photovoltaic installations by installers and architects. In this paper, the calculative accuracy of TRNSYS, Archelios, Polysun, PVSyst, PV*SOL and PVGIS is being examined in comparison to the real electrical energy generated by a grid-connected 19.8 kW p photovoltaic installation. The assessment has been performed by using the climatic data which have been recorded at the site of the real PV park over the same calendar year. Our results displayed that the software packages tend to overestimate the global irradiation received by the PV modules, but still significantly underestimate the electrical energy generated by the installation.
