Solar PV Module

Bifacial and BIPV

The KOSOL PV module generates energy when light falls on its surface. In the case of a bifacial module, solar power is generated through both the front and back glass surfaces, where they absorb sunlight. Some of the light that is not absorbed by the front surface is reflected (albedo) and then absorbed by the back surface of the module, resulting in additional power generation. This occurs due to the different characteristics of each surface. The efficiency and bifacial nature of the module come into play when both sides receive light. It's important to note that the power generation on the rear side of the module may not always be exactly equal to the front side. The ratio between the power generated on the rear and front sides is known as module bifaciality. Bifaciality can vary depending on the type of cell used in the solar module.
