Solar Panel as Alternative Energy Source for Water Pump Control System at the Floating House in the Palembang Musi River Bank

Abstract

Solar energy is a renewable energy and has unlimited availability. Indonesia is one of the countries traversed by the equator and has a tropical climate and sunshine throughout the year. Solar panels are a system that can convert sunlight energy into electrical energy by utilizing the photovoltaic effect. Based on data from the BMKG Climatology Station Class I South Sumatra, Palembang City has an average of 3.75 hours of radiation during February and May 2021. The house, which is located on the banks of the Musi River in Palembang, has very good potential for the construction of a solar panel system in the area, because the area has an open area so that the lighting is needed by solar panels. Based on measurements made in the area, the average light intensity ranges from 50000 Lux – 70000 Lux with a voltage generated of 38 – 43 Volts on 22 and 25 July 2021. The solar panel system built will be used as alternative energy in the control system. AC water pump in a floating house along the Musi River, Palembang. Therefore, a solar panel system was built which is expected to be able to replace the role of conventional electricity used today. The solar panel system that is built must be controlled and monitored properly so that its use becomes more optimal. The control system is built using several sensors including the ACS712 Current Sensor, Voltage Sensor, and the PZEM004T AC power sensor with an accuracy level for each sensor.
