SOLARBRUSH walks on solar modules with high inclination of at least 30 degrees. The robot is designed for dry cleaning. It brushes sand off the modules into the mounting space in between. Suction cups, also known as vacuum bulbs, attach the robot to the surface. It detects the end of the modules and steps over the frame of the modules onto the next module. It does so for the maximum distance of 20 mm. The robot carries an rechargeable and replaceable battery.
SOLARBRUSH uses standard components from the industry, keeping costs for its maintenance low. The robot cleans the solar modules in a structured pattern, unlike most robots for domestic use. The gentle brush and the light weight of 2.5 kg are designed to be sensitive to the surface. The battery lasts for 2 hours which is to be increased. The target velocity is 1 m² / minute.
