How to choose Gokin Solar's monofacial and bifacial modules?

Given the current price difference between monofacial and bifacial modules, when the back of the bifacial module is unobstructed, the additional light on the back significantly enhances power generation. Additionally, the dual-glass encapsulation structure of bifacial modules offers better resistance to environmental corrosion, such as moisture and salt spray. However, for installations on mountainous terrain or flat distributed systems, monofacial modules are a more suitable choice.
