Abstract
Electric energy is one of the most important human needs and is essential for daily life. Almost all human activities require electric energy, and a shortage of it can disrupt these activities. Electric energy from solar power plants is the result of converting solar energy into electricity using solar panels. solar power plant is a clean and renewable energy source because it does not produce greenhouse gas emissions or air pollution during normal operation. One aspect of choosing solar power plants is its adaptability to the location, as it is highly feasible and easy to implement in isolated and island areas without requiring much time. Challenges in the field after installing solar-powered public street lighting include monitoring battery conditions and theft cases. Therefore, the proposed solution to address these issues is to install sensors that can monitor battery conditions (INA219 sensors) and prevent theft (Neo 7M GPS sensor). The sensor data obtained is sent via the GPRS network using the SIM800L module to the user for real-time monitoring. The sensors installed on the PJU PLTS can continuously address the challenges encountered in the field. Testing results showed an average error of 0.81% for voltage and 1.45% for current measurements. The NEO 7M sensor outperformed the smartphone GPS with a discrepancy of 2.946 meters. The battery charging duration was found to be 570 minutes, and the battery usage duration was 2.5 hours.
