What is Solar panel cleaning?
As a rule, residential rooftop-mounted PV panels are naturally cleaned by seasonal precipitation. However, excessive accumulation of bird poo or other dirt can lead to performance reduction. A solar system can be washed with a garden hose in late evening or early morning, when it is not hot. After that, one can wipe it gently with a soft cloth or sponge. Optionally, an expert can be hired for the job. As for utility-scale ground-mounted PV installations, they are usually cleaned by robots in a fast and less water-consuming way.
