Solar Grass Cutter

This comprehensive research paper presents the complete design, development, and performance evaluation of an innovative solar-powered autonomous grass cutting system. In response to growing environmental concerns and the limitations of conventional grass cutting technologies, this study introduces a fully sustainable alternative that combines renewable energy utilization with intelligent automation. The system integrates a high-efficiency 25W monocrystalline solar panel with an optimized 12V8Ah lithium-ion battery storage system, powering a specially designed 12V DC motor capable of achieving 5859 RPM through an advanced gear reduction mechanism. The cutting apparatus features durable stainless steel rotary blades mounted on a lightweight yet robust PVC chassis weighing approximately 15kg, incorporating a sophisticated 360-degree wheel system for enhanced maneuverability. Extensive field testing demonstrates the system’s capability to maintain consistent cutting performance across 300-400 m² per hour while operating at noise levels below 60dB. The research further examines the economic viability, environmental benefits, and practical applications of this solar-powered solution, presenting a compelling case for its adoption in both residential and commercial lawn maintenance scenarios.
