Quick Answer
Bifacial panel maintenance poses unique challenges due to the added complexity of handling both front and back surfaces. Regular inspection and cleaning of both sides are essential to maintain optimal performance. Dirt and debris accumulation can lead to reduced efficiency.
Inspecting and Cleaning Bifacial Panels
Inspecting bifacial panels requires a two-step process: examining the front and back surfaces separately. This can be achieved using a ladder or aerial lift for the back surface, while the front side is easily accessible. For the back side, use a 2-foot wide squeegee to ensure thorough cleaning of the larger surface area.
Addressing Specific Issues with Bifacial Panels
One of the primary concerns with bifacial panels is the increased risk of backsheet damage due to debris accumulation. To mitigate this risk, use a soft-bristled brush or squeegee to gently remove dirt and debris from the back surface. When cleaning the backsheet, use distilled water and a mild detergent to prevent damage to the panel’s coating.
Ensuring Regular Maintenance Schedules
Regular maintenance of bifacial panels is crucial to maintaining optimal performance. Schedule annual cleanings and inspections to prevent dirt and debris accumulation. During the inspection, check for any signs of panel damage or wear, such as cracks, delamination, or broken glass.
