Abstract
In China, systemic techno-economic analysis for solar tracker has been absent. To fill the blank, by taking the economic analysis of solar tracker application as the research object and using the LCOE method widely used internationally, the techno-economic analysis model of solar tracker was established according to conditions in China. Influence factors on LCOE were analyzed by using the established model, and the relationship between each cost factor and the cost component of energy leveling of tracker was further studied. In addition, the calculation method of investment payback period based on energy leveling analysis was established, and the influence of various factors on investment payback period was revealed through an example calculation. The research results will help to measure the economy of tracker application more accurately and comprehensively, and promote the popularization and application of solar tracker. The economic analysis model of solar tracker application was established by using LCOE method. The influence factors and cost component of LCOE were analyzed with the model. The payback period of solar tracker investment was also analyzed based on LCOE method.

Summary
PV generation can increase the power generation of photovoltaic system by using tracker, but with capital investment, the cost increases. Fixed installation is the best cost-effectiveness ratio, and the payback period of uniaxial tracker and seasonal tracking is significantly prolonged [9]. It was found that the power output of the photovoltaic system with single-axis tracker increased significantly in the morning and afternoon compared with that of the fixed installation system under the condition of considering the tracker energy consumption [10]. Many scholars have done a lot of research on solar trackers These studies mainly focused on the design, performance, feasibility or technical and economic analysis of various solar trackers. Regarding the solar tracker as an energy system, with the LCOE method widely used in the world, the paper took the economic analysis of the application of solar tracker as research object and tried to perform its cost-benefit analysis. It was hoped that the research results would be helpful to measure the economy of solar trackers more accurately and comprehensively, and promote the popularization and application of solar trackers
