摘　　要：文章利用PVSYST软件对西班牙帕尔玛地区采用固定式支架、单轴跟踪系统(倾角为当地纬度)、双轴跟踪系统的光伏电站的电价进行了分析。结果表明,使用单轴跟踪系统可以使得电价降低11.1%～20.2%,双轴跟踪系统的性价比明显不如单轴跟踪系统。在我国的甘肃、宁夏、青海、内蒙和新疆等省区有不少地方与帕尔玛有着相近纬度且太阳能资源更为丰富,在那里使用单轴跟踪系统对于电价的降低效果更为明显。Using PVSYST software, the paper analyzes electricity tariffs of PV station equipped with fixed stand, single-axle tracking system （dip angle is the local latitude）, double-axle tracking system at Palma region, Spain. The analysis result indicates that single-axle tracking system can reduce the tariff by 11.1%~20.2% and cost performance of double-axle tracking system is obviously worse than that of single system. Many regions in China like Gansu, Ningxia, Qinghai, Inner Mongolia and Xinjiang, have the similar latitude as to Palma and richer solar resources, where single-axle tracking system will have more obvious tariff reduction.
