One of the problems with Solar Power Plants (PLTS) is the angle of inclination during installation. Errors in determining the angle make PLTS not produce power optimally. In order for the power generated by PLTS to be optimal, the angle of inclination of the solar panels must be adjusted so that they face directly towards the sun. This study designed a dual-axis solar tracker using a microcontroller, a Light Dependent Resistor (LDR) sensor, and a servo motor. The effect of the number of sensors and tracking delay is analyzed to determine the output power of solar panels with different configurations. Testing from 07:00 to 17:00 for 2 days of testing, 2 days of tracking delay testing, and 3 days of testing of 3 PLTS installed. First on the dual-axis solar tracker and the rest with tilt angles of 0o and 30o. The results of the design of a dual-axis solar tracker on the x-axis rotates from 0o to 20o, while the y-axis rotates from 35o to -17o. Tests using 4 LDR sensors affect changes in the angle of the solar panels. Tests show tracking delay every 30 minutes and 1 hour has no significant effect. The power generated at the tracking delay every 30 minutes is greater, but the power consumed is also greater. During the test it was found that with a tracking delay of 1 hour it produced 1.76% greater net power. Final testing of dual-axis solar tracker and PLTS with tilt angles of 0o and 30o. During testing, it was found that the dual-axis solar tracker produces 16.89% greater power than at a tilt angle of 30o and 11.42% greater than an angle of 0o
