Commercial Solar Panel Cleaning Service
Oltec Facilities Management understands that even a well maintained PV system can underperform if panel surfaces are neglected. Our commercial solar panel cleaning service, available across Barnard Castle, Durham, removes dust, bird droppings, tree sap, lichen and decomposed leaves that block sunlight absorption. Uric acid and organic residue can gradually damage cells if left untreated, so regular cleaning is essential to maintaining manufacturer level performance and preventing costly long-term degradation.
