particular installation. The Structure Shading Factor varies with
racking system design, irradiance, albedo and height of module


TheRearsidemismatchlossesareproportionaltothealbedo,height
of the modules above ground and structure shading factor. The
irradiance non‐uniformity on the rearside results in mismatch
generally as the albedo increases and installation height of the
modulesarelowertotheground.

Bifacial modules use direct, reflected or diffuse sunlight at the
rearsidetogenerateadditionalpower.Therefore,itisrecommended
