RANCANG BANGUN ALAT PEMBERSIH SOLAR PANEL MENGGUNAKAN WIPER DAN ROLLING BRUSH SECARA OTOMATIS BERBASIS MQTT

Abstract

Electrical energy has an important role in human life, most electricity sources still use coal and petroleum, causing these sources to become increasingly depleted, therefore alternative electrical power sources are urgently needed. The use of solar energy is an effort to reduce global carbon emissions. In the implementation of solar panels as a daily generator of electrical energy, there are several factors that cause the performance of the solar panel to decrease, such as the outer layer of a solar panel being covered by dust or other obstructing materials. Several studies have been carried out to optimize the power output from solar panels by using solar panel cleaning systems. This final project aims to design and build a solar panel cleaning device using wiper and rolling brushes automatically based on MQTT. From the test results of this tool itself, it was found that the average voltage was 0,29 V without using water and 1,07 V when using water. Then, from the results of the experiments and tests, it was found that the voltage suitable for driving the DC motor for the rolling brush was 7.73 V, 8.01 V for the right wheel motor, and 9.05 V for the left wheel motor.
