Optimization Analysis of Distributed Photovoltaic Generation System Design Based on Substituting 50 kW Inverter for 100 kW Inverter

Promoting the whole-county (city or district) construction of rooftop distributed photovoltaic generation is an important part in realizing the two major national strategies of "carbon peak, carbon neutrality" and rural revitalization. In this paper, a distributed photovoltaic generation system design scheme based on substituting 50 kW inverter for 100 kW inverter is proposed for industrial and commercial rooftop photovoltaic projects. Through detailed comparative analysis, it is concluded that the design scheme entailing the use of 50 kW inverters is more economic and cost-effective than using 100 kW inverter.
