Abstract

This paper describes about solar energy is one of the energy sources that won’t terminated. Solar energy can be easily converted into electrical energy by using solar panels. Solar panels that are placed horizontally on the ground, the solar panel cannot absorb the light perfectly. Therefore, solar panels require an automatic solar tracking system to increase the efficiency of the solar panels. In this study, a solar tracker has been designed using a light dependent resistor (ldr) sensor based on the stm32 microcontroller. From the results of the study, the increase in power obtained from the use of a solar tracker was 27.97%. In static solar panels, the time required to fully charge the 12v, 7ah lead acid battery is 5 hours 10 minutes, while using a solar tracker the lead acid battery charging time is 3 hours 30 minutes. The use of a solar tracker saves battery charging time for 1 hour 40 minutes compared to static solar panels.
