Utilization of Solar Power Plants (PLTS) To Operate DC Pumps 250 Watts For Irrigation of Rice Fields in Nagari Batu Taba

Abstract

Indonesia has a very abundant source of renewable energy, namely solar energy. This energy can be converted into electricity using photovoltaic (PV) technology in a system called Solar Power Plants (PLTS). The use of solar power plants in rice field irrigation systems is an environmentally friendly solution that has the potential to increase efficiency in the agricultural sector. The purpose of making this tool is to evaluate the performance of a 250 watt DC pump operated with energy from a 600Wp monocrystalline solar panel, as well as to control the system and use the battery as a storage of electrical energy generated by the solar panels. The test is carried out by measuring the intensity of sunlight, current and voltage from solar panels, as well as current and voltage in the battery. The data obtained were analyzed to determine the reliability and efficiency of the system in meeting irrigation needs for rice fields. The results obtained show that the solar panels can meet the needs without experiencing voltage drops, and the system is able to operate the DC pump stably during the day. With this optimal performance, the system can fill an 800-liter tank in 4.6 hours. The application of this system to rice field irrigation can be an alternative for farmers who are far from conventional electricity access and reduce their expenses.
