Solar panels are continuously exposed to the environment. Accumulated dust, bird droppings, pollen, and snow significantly reduce their energy efficiency. A fixed dry cleaning robot provides an automated, low-maintenance solution to ensure panels operate at optimal performance. Studies have shown that uncleaned panels can lose up to 20-30% of their output, making regular cleaning crucial for long-term energy yield and return on investment.
