Abstract:
To maximize sunlight absorption by forming a perpendicular axis between the sun and the solar panel. A
method which could be implemented on the solar panel system that could follow the sun’s movement is
needed. On this design, the system uses a light diode sensor (LDR) that functions as the light detector, an
Atmega238P-PU microcontroller as the command logic storage, and a servo motor as a mover to dislocate the
position of the solar panel with Internet of Things (IoT). In the solar panel test which runs for 11 hours using
the dual-axis solar panel tracker has yield a power of 9.4 W and after passing the MPPT control battery, it
gives an average of 10.6 W. Compared to using a static solar panel method, it only yields a power of 6.8 Watt,
and after passing the MPPT control battery, it gives an average power of 9.25 W.w
