Initially, he planned to remove dust from the surface of the photovoltaic cells using a cylindrical brush mounted on the rear of a train. “However, we realised that each time a train passes, it creates an airflow that sweeps away all the dust,” he said.

- zdragnar 3mo agoThat seems pretty optimistic in the long run. Even a high power leaf blower won't get all the dust off of a dirty surface, especially if any sort of hydraulic oil, bearing grease or other viscous fluid mists onto the surface.

- Ma8ee 3mo agoOne thing that has struck me with our own solar panels is that they have to be very dirty before I notice any significant degradation in efficiency. And when they do get completely covered in pollen or leaves, a brief rain is usually enough to clean them.
- panick21_ 3mo agoUntil you realize that polan is super stick and is really had to remove. I had a table outside and just 'blow away' dust didn't work at all. You need to actually clean with friction, water and cleaner.
