“…It has the benefit of being able to provide highly accurate estimates of the PV system that can be installed at the proposed location, monthly and annual power production, performance ratio, layout of PV system, number of inverters and PV modules, single line diagram (SLD), losses in photovoltaic system, shading analysis, electric cabling selection, global horizontal irradiance (GHI), diffuse horizontal irradiance (DHI), plane of the array (POA) irradiation, temperature indicators, computer-aided drafting (CAD) tools and SketchUp shading integration. It is also feasible to select required components of system such as rating and type (Si-Mono, Si-Poly) of photovoltaic modules, inverters rating, tilt angle, azimuth angle, orientation (horizontal and vertical mounting) of photovoltaic modules, frame size, array row arrangement, inter-row spacing between PV array, and AC/DC electric cables during the design process for PV systems (Habib et al, 2023b;Habib et al, 2023c). When developing a simulations model of PV plants, PVSyst incorporates meteorological data from the NASA-SSE (Solar System Exploration, 2023), Metronome (Meteonorm Software, 2023), and Solar Prospector (Solar Prospector, 2021) databases.…”
