Abstract
The design of a watt peak meter of solar panel has been carried out using an LDR sensor to obtain the strongest light as the sun moves. The electronic circuit used includes LDR KY018, WEMOS ESP32, servo motor, Solar Charger Controller, INA219 Power Sensor, Battery and 10 A / 5V Relay. The mechanical structure uses angle iron construction which is assembled in such a way as to support solar panels with the SUNLITE Model 156P-20 type. Solar panels are positioned on 2 poles and attach the bolts as the rotary axis. LDR that gets sunlight will provide input to the WEMOS ESP32 to drive the servo motor in line with the direction of the sun in the east - west direction. The result led to an average 93,7% close to number as stated in the data specification of solar panel.
