Governments around the world are prevalent to seize time to formulate and implement action plans for the peaking and neutralization of carbon dioxide emissions.Solar photovoltaic power generation will be bound to gradually become one of the mainstream directions to replace traditional energy power generation.In this paper

the photovoltaic power stations in the Middle East

where is rich in solar resources

are taken as the research object.Through the research method of simulation

the corresponding relationship between levelized cost of electricity (LCOE) and power station capacity ratio and photovoltaic module type is simulated and analyzed respectively.It is found that based on the current labor

material and machine prices of the area

for the centralized utility solar photovoltaic power plants in the Middle East

the N-type photovoltaic module is more conducive to reducing the EPC-LCOE than the P-type module

and the potential DC/AC ratio corresponding to the lowest EPC-LCOE is around 1.34

which can be used as a reference for the bidding of photovoltaic power plants in this region.
