Technical, Economic, and Environmental Feasibility Assessment of Grid‐Connected Photovoltaic Power Generation Systems with Different Tracking Models in Hefei, China

Abstract

Herein, the feasibility of a grid‐connected photovoltaic (PV) power generation system with five tracking models in Hefei is evaluated comprehensively. The comprehensive evaluation of grid‐connected PV power generation system mainly includes three aspects: technology, economy, and environment. The results show that the performance ratio of grid‐connected PV system with dual‐axis tracking device is the highest among the five kinds of PV systems with a value of 81.2%, while the performance ratio of grid‐connected PV system without tracking device is the lowest with a value of 77.3%. The grid‐connected PV system with dual‐axis tracking device is economically attractive, so users can be encouraged to purchase and install such systems to meet their electrical energy needs in Hefei. Furthermore, the grid‐connected PV system with dual‐axis tracking device is the most environmentally friendly and contributes to carbon emission reduction. Finally, it is concluded that the adoption of dual‐axis tracking grid‐connected PV power generation system in Hefei area is very attractive, and can provide a certain reference for the local promotion and use of such grid‐connected PV power generation system.
