Design and Fabrication of Solar Grass Cutter

This paper introduces a solar-powered grass cutter designed to operate efficiently using Light Dependent Resistors (LDRs) and an innovative solar panel configuration. The system features an upside-down solar panel with a convex lens to focus sunlight onto a second panel, which reflects the light to a third panel positioned above it. This design maximizes energy absorption and ensures optimal performance even in low-light conditions. The LDRs enable automatic activation and deactivation of the system based on ambient light levels, making it energy-efficient and user-friendly. Experimental results demonstrate the system's effectiveness in reducing energy consumption and improving operational efficiency. This project highlights the potential of solar energy in sustainable lawn maintenance solutions. Key Words: solar energy, grass cutter, LDR, convex lens, energy efficiency, automation
