摘要

The operating cost reduction of photovoltaic (PV) systems is an important way to increase its economic viability for stakeholders. In this study, an inverter sizing ratio (ISR) analysis is carried out in order to quantify its potential benefit in the context of building-integrated PV systems and PV distributed generation in the central region of Brazil. An algorithm was created to analyse the ISR considering 12 years of measured climate data and data provided by manufacturers of system components. Among three analytical methodologies discussed in this study, the power limitation analysis seems to be the best reference for design adjustments related to a specific location or energy market. By that, a potential reduction over 10% of levelised cost of energy can be achieved in case of varying ISR from the unity value (theoretical) to its new fitted value.
