Techno-Economic Analysis of Alternative PV Orientations in Poland by Rescaling Real PV Profiles

This paper presents factors affecting the effectiveness of photovoltaic (PV) plants and issues occurring in the distribution system network due to the high penetration of conventionally designed PV plants. Factors analyzed in this paper are shading, distance between panels, location of PV plants, European grid code requirements, and network constraints. Their impacts on the effectiveness of the PV power plant are presented one by one. Furthermore, the 1-year power profile of a real PV plant is rescaled to different orientations, and the energy effectiveness of different variants is compared. Finally, the economic aspects are considered by multiplying the energy produced by the energy prices. At the end, final conclusions are given and further research is outlined.
