In recent years, the excessive consumption of conventional fossil energy, energy shortage and environmental deterioration have become more and more serious. It has become a global consensus to accelerate the transformation of energy use patterns and resolve the energy crisis.Distributed photovoltaic power generation system has the advantages of flexible investment, simple operation and maintenance, local consumption, etc. The industry has a good development trend, and has gradually become a pillar industry in the field of new energy power generation in China.Taking electricity enterprise as the research object,an objective, effective,realand reliable principle is put forward to evaluate the investment value of photovoltaic enterprises, which are based on the current value and potential value, covering 20 secondary indexes. The possible risk factors are analyzed and photovoltaic investment enterprise customer value evaluation system is set up so as to provide investors with a certain reference value. Through big data analysis of the photovoltaic investment value of enterprises, selecting enterprises with photovoltaic investment value to achieve precision marketing, so as to leverage the large?scale development of distributed photovoltaic power generation industry, which is of great significance to solve the current energy crisis.
