RoboSolar Cleaner — Demo video

Solar panels lose a significant amount of power when dust, sand, bird droppings and other dirt build up on their surface, a dirty panel can lose 5–30% of its energy output, and the loss keeps growing until someone cleans it. Today that cleaning is done manually: it is slow, labor-intensive, wastes water, worse still operators usually clean on a fixed schedule thereby leaving dirty panels losing money for weeks because nobody knew they were dirty. RoboSolar Cleaner is an autonomous solar-panel cleaning robot that cleans only when it is needed, and only the panels that need it. Five custom-designed circuit boards, designed with muse-wonder-1.0 specifically for Kicad work together as one system: 1. A Soiling Station compares a clean reference mini-panel against an exposed dirty one to measure exactly how much power soiling is costing. 2. A Panel Node on each solar array measures real voltage and current, confirming the loss. 3. A Weather Node checks rain and wind so the robot never cleans in unsafe conditions. 4. Meta's Muse Wonder (muse-wonder-1.0) receives this sensor data and recommends which panels to clean and in what order 5. The Robot then drives alongside the panels, extends a brush arm onto the panel surface, cleans it, returns to its Dock to recharge and refill its water tank, and verifies the panel's power has recovered.
