This document summarizes a study on improving solar panel efficiency through the use of a sun-tracking system and Fresnel lens. A microcontroller-based system was designed to track the sun's movement using light sensors and motors to keep the solar panel perpendicular to the sun's rays. A Fresnel lens was also used to concentrate sunlight on the panel. Experimental results showed the sun-tracking system improved efficiency over a stationary panel and that additional gains were made when combined with the Fresnel lens. Graphs of output data over time demonstrated increased power production from the sun-tracking and concentrated system compared to the stationary panel alone.
