This study presents the state-of-the-art for gathering pertinent global data on the size ratio and provides a novel inverter sizing method.

The optimal sizing ratio (RC,max) of a PV system depends on the PV/inverter cost ratio (T). The correlation relating the optimal sizing ratio with the cost ratio for low, medium and high efficiency inverters and for horizontal, vertical and 45° inclined surfaces and three tracking strategies are shown in Fig. 12.

The analysis explores the trade-off between PSR, annual energy yield, and inverter clipping. An optimal PSR of 1.19 is identified, balancing energy capture (up to 2000W inverter capacity) and economic efficiency. This approach promotes cost-effective inverter selection and wider PV adoption.

This paper aims to select the optimum inverter size for large-scale PV power plants grid-connected based on the optimum combination between PV array and inverter, among several possible.
