MODELING AND FINANCIAL ANALYSIS TOOLS FOR PV GRID-CONNECTED SYSTEMS

Integration of photovoltaic (Py) technology in buildings must always b e realized by taking into account rational criteria in PV system desig n, This paper presents analytical models to estimate the energy and ec onomic performances of PV grid-connected systems in non-ideal situatio ns, i.e. considering spatial constraints (orientations, possible shado wing), technical characteristics and energy interchanges with the elec tricity grid, It offers a useful tool for the PV system designer, avoi ding otherwise complex performance calculations.
