5.3 Ground Mount Applications for Bifacial modules
Clamp
6
Various environmental and installation parameters affect bifacial
gain. Albedo is a measure of the amount of light reflected from the
7
Clamp
ground surface. A higher albedo factor will increase irradiance on the
8
Clamp
backside and result in higher bifacial gain of the module. The surface
Clamp
9
conditions, month of the year, time of day, GHI and DNI both influence
Clamp

the amount of incident rearside irradiance.
Maxeon recommends to check with solar module mounting hardware

Bolt
supplier in order to determine the Structure Shading factor of your
particular installation. The Structure Shading Factor varies with
racking system design, irradiance, albedo and height of module

installation above ground and has an overall impact on the rear side
irradiance mismatch.
Clamp

Clamp
8
The Rearside mismatch losses are proportional to the albedo, height
Clamp

of the modules above ground and structure shading factor. The
irradiance non‐uniformity on the rearside results in mismatch
6
generally as the albedo increases and installation height of the
Clamp
modules are lower to the ground.

5.4 Rooftop Applications for Bifacial modules
Clamp
9
Bifacial modules use direct, reflected or diffuse sunlight at the
Bolt
rearside to generate additional power. Therefore, it is recommended
to use bifacial modules installed on flat roof applications.
In order to maximize the bifacial gain at the rooftop applications the
following parameters listed below should be considered:
•Surface Albedo
•Roof Integrity
•Module Tilt Angle
•Module Elevation
•Structural Backside Shading
