Energy simulation of p-PERC bifacial modules based on different installation environment

The bifacial-cell module can significantly increase the power output due to the back power generation gain, and is becoming research hot. In this paper energy simulation analysis is based on three types of systems in different regions, and the installation tilt, ground albedo and height above ground are compared respectively. The irradiation is dominating to produced energy. The modules located in Yinchuan under the situation of albedo 0.2, tilt 15° could generate 85.2 MWh/year, which is 6.1 MWh/year higher than the modules located in Beijing under the situation of albedo 0.8, tilt 30°. The modules generate more power under the situation that the installation tilt is close to latitude, the optimal tilt of Beijing, Yinchuan and Guangzhou is 30°, 30-35° and 15°. The higher the albedo of the ground, the greater the impact of tilt changes on produced energy. Meanwhile, the increasing height above ground promotes to the higher energy. And the produced energy is more sensitive to the variable value of ground albedo compared with height.
