Analysis of the Impact of DC Cable Voltage Drop and Low-Voltage AC Cable Voltage Drop on Investment Return in Photovoltaic Power Generation System

The purpose of this paper is to analyze the impact of DC cable and low-voltage AC cable voltage drop on the investment return of photovoltaic power generation system by analyzing the changes of DC cable engineering quantity and project investment income under different DC cable voltage drops in photovoltaic power generation systems and the changes of low-voltage AC cable engineering quantity and project investment income under different low-voltage AC cable voltage drops. When the voltage drop of DC cable is controlled at 1.5% and the voltage drop of low-voltage AC cable is controlled at 1%, the investment return rate of the project is better.
