About

Sun Effect is a green energy company specializing in developing innovative products for environmental improvement. The company develops, manufactures, and markets automated robotic systems for wet cleaning of solar panels. Their robots are designed to clean solar panels on ground-mounted systems, industrial roofs, chicken coops, cowsheds, greenhouses, and commercial areas. The robotic system provides thorough, uniform, and continuous cleaning year-round, eliminating the need for manual washing and significantly improving output for customers. The system is highly water-efficient, using approximately half a liter of water per panel per wash, and includes a water softener to prevent limescale buildup. The robotic system can be operated and controlled remotely via a user-friendly application that also provides reports and statistics on system activity. The robots and system infrastructure are made of highly durable materials resistant to harsh outdoor conditions and UV radiation, designed for long-term operation with minimal wear and maintenance. The systems are designed to operate during the night and early morning when humidity is maximal. After cleaning, the robots park in their docking stations outside the panels, avoiding wasted daylight hours or shading the panels.
