One of the new and renewable energy is the utilization of sunlight into electricity. which can
be used to be converted into electrical energy using solar panels. Installation of solar
panels that are installed for garden lights so far are often still placed in a static position
(silent) at an angle of 90⁰, while the sun moves from sunrise to sunset. Because it will
cause maximum energy absorption in solar panels placed in a static position only at
12:00. To overcome this problem a system is needed to track the position of the sun so
that it is always perpendicular to the surface of the solar panel. Design and build Garden
lights with a solar light tracking system on a microcontroller-based solar panel will later be
made to move as it follows the direction of the sun's movement every hour, from sunrise
to sunset. This tool will detect the time setting inputted by Real Time Clock (RTC) which
is then processed by a microcontroller to drive a servo motor that functions as a solar panel
drive machine so that the position of the solar panel will always be perpendicular to the
sun throughout the day and the absorption of energy in the solar panel will more leverage.
From the results of tests that have been done, the increase in the voltage of solar panels
using a tracking system compared to solar panels without using a tracking system is 7.85%.
