What is bifacial gain in PV modules?
Definition:
Bifacial gain refers to the additional electricity generation of bifacial photovoltaic modules after they receive extra light from the environment on their back sides. This additional electricity generation is in comparison to monofacial photovoltaic modules, as monofacial photovoltaic modules can only absorb the direct light on their front sides.
Working Principle:
Front-side Absorption: Similar to single-sided modules, the front side of bifacial modules can absorb direct sunlight.
Back-side Absorption: The back side of bifacial modules is also capable of absorbing various kinds of light from the environment, including light reflected from the ground, light reflected from surrounding objects, and scattered light from the sky.
Gain Range:
Depending on different environmental conditions and installation methods, the gain of bifacial photovoltaic modules can range from 4% to 30%. The specific gain value depends on the influencing factors mentioned above.
