Quick Answers
Frequently asked questions
Answers drawn from the specification tables and datasheets above — ask our sales engineers for anything model-specific.
How much extra yield does robotic solar panel cleaning add?
Automated cleaning raises generation by 6 – 20% on average, with dust removal of 99.5%.
Do COTECH cleaning robots need water?
No — the full-auto robot cleans dry with microfibre and airflow, suited to desert and arid sites; the semi-auto unit offers both dry and wet modes.
Which COTECH cleaning robot fits which plant?
The self-powered full-auto robot lives on the array (slopes ≤25°) and cleans on schedule 24/7; the portable semi-auto robot is carried and driven by one person at 18 m/min via 100 m remote and app; the RTK trackless robot navigates ground plants to ±1 cm and covers 1200 m²/h on a 3 h runtime.
Can the cleaning robots be managed remotely?
Yes — cloud fleet tools provide scheduling, remote monitoring and OTA updates across the fleet.
