Abstract：By means of simulation,the authors have analyzed the power generation effect with different PV support brackets in allusion to the characteristics of several PV support brackets and in combination with practical engineering cases，compared the economy of fixed and tracking support brackets by calculating the payback period. The research results have a positive effect on improving the annual unit power generation of PV systems.

Key words：distributed PV;fixed support brackets;tracking support brackets;flat single‑axis tracking system;oblique single‑axis tracking system;system power generation;unit power generation;economic analysis
