Quick Answer
Common Mistakes When Installing Bifacial Solar Systems include poor orientation, inadequate cleaning schedules, and insufficient module spacing leading to reduced energy yields.
Inadequate Bifacial Panel Orientation
Bifacial solar panels require a specific orientation to optimize energy production. Incorrect installation can result in energy losses of up to 20%. Installers should ensure panels are tilted between 20° and 40°, with a surface angle of 5° to 10°. This configuration maximizes both front and rear panel efficiency.
Suboptimal Shading and Spacing
Bifacial panels require a clear path for reflected light to reach the rear side of the module. Shading from trees, buildings, or other obstructions can reduce energy yields by up to 40%. To mitigate this, ensure a minimum of 1 meter of clearance between modules and a 3-meter radius around the entire array. This spacing allows for optimal rear-side illumination and minimizes shading effects.
Inadequate Cleaning and Maintenance
Bifacial panels are more susceptible to dirt, dust, and water spots due to their increased surface area. Failure to regularly clean and inspect the panels can result in energy losses of up to 10%. Installers should schedule bi-annual cleanings and perform visual inspections after each cleaning to ensure optimal performance. Regular maintenance also helps to prevent potential damage from water spots or other environmental factors.
