Vertical Power Generation Technology of Heterojunction Solar Cell

In this study, the power generation difference between the east-west and the north-south orientation of the vertically installed heterojunction solar cell (HJT) modules was deeply discussed. East-west oriented HJT module has 30% higher power generation, especially in desert photovoltaic (PV) with a bimodal distribution. While the south-north one has a single peak, the same as normal PV modules. Vertical power generation technology of HJT also has less land occupation, which is of great significance for optimizing the design of photovoltaic systems.
