摘　　要：分别对敦煌、上海2地区采用高倍聚光和双轴平板(晶体硅组件配双轴跟踪器)的光伏电站的发电成本进行了比较。结果表明,在当前市场条件下,敦煌地区高倍聚光的发电成本比双轴平板高40.2%,上海地区高倍聚光的发电成本比双轴平板高109.5%。高倍聚光的发电成本明显高于双轴平板,2者之间的差距与当地的直接辐射强度有关,直接辐射越弱,2者之间的差距越大。A comparison is made in this paper of the power-generating cost of photovoltaic plants in Dunhuang and Shanghai region installed with high concentration photovoltaic system（HCPV） and crystalline silicon module photovoltaic （PV）system with 2-axis trackers.The result shows that under current market condition,the power-generation cost of HCPV is 40.2% higher than that of the photovoltaic system with 2-axis trackers in Dunhuang region and 109.5% higher in Shanghai region,indicating that the power-generation cost of HCPV is substantially higher than that of PV with 2-axis tracker.The difference between them is related with the direct irradiation intensity in the region,and the weaker the direct irradiation is,the higher their differences are.
