Solar photovoltaic power generation system is mainly composed of photovoltaic module, inverter module, power distribution module and monitoring module, etc. This paper analyses the key technical difficulties such as building structure adaptability, shadow effect, space limitation, environment adaptability, power consumption and grid access, power station monitoring and maintenance. And then it gives the solution measures in the application of solar photovoltaic power plant in cement factory, and puts forward the photovoltaic module in the cement factory. The arrangement and selection of PV modules in the cement plant, the electrical design of PV power station, and the construction organization plan are proposed. Through the analysis of investment returns, it can be seen that the PV power station in cement enterprises can achieve the goal of multi-year stable income with one investment.
