两种公路照明用太阳能接收装置的经济性分析

The Economic Analysis of Two Types of Solar Receivers in Road Illumination

国内外的太阳能接收装置一般分为两种:跟踪阳光式和非跟踪阳光式。评价太阳能接收装置的经济性指标通常有:装置组成经济性、光伏转换率的经济性、日常运行维护经济性和能源、材料使用的经济性。从经济指标的几个方面分析,跟踪式太阳能接收装置用于公路照明的经济性全面优于非跟踪式。可以看出,跟踪阳光式接收装置用于公路照明的经济效益是非常巨大的,而且低碳环保,值得全社会推广和应用。

At home and abroad,there are usually two types of solar receivers：one is the tracking-sun type and the other is non-tracking type.The economic indicators using to evaluate the solar receiver are the economics of the structure of the devices,the photovoltaic conversion rate,the routine operation and maintenance,and the utility of energy and materials.Analyzing from the economic indicators above,the tracking-sun type is much better than the non-tracking type when used in road illumination.We can see that it will bring huge profit using the tracking-sun type of receiving equipment in road illumination which should be recommended and applied because it is low-carbon and environmentally friendly.
