Abstract:

Solar panels are designed to convert solar energy into electrical energy. This electrical energy is then sent to a battery or an inverter, which converts it into usable power. The power produced by the panels cannot be monitored directly as it is being generated. This system typically consists of a solar panel monitoring device that measures the voltage, current and temperature of the solar panel. This data is then used to determine the efficiency of the solar panel and identify any potential problems that need to be addressed. Monitoring the performance of the solar panel, it helps to ensure it is operating at its peak efficiency and reducing the risk of potential damage. A 100 Wp panel and a 12V 45 AH battery are used in the solar power plant battery charging process. The voltage sensor needs to be calibrated so that it can accurately measure the voltage from the solar panel and the battery. This is important because the voltage must be within certain parameters in order for the battery to charge safely and efficiently. By monitoring the performance of the solar panel and the voltage sensor, potential risks of damage can be minimized. Calibration is followed by determining the programme and low and high values. Using the Arduino IDE software, the programme is then input into Arduino. The results of the DC voltage sensor measurement and the programme used were then compared. A 3-day monitoring process is carried out for PLTS battery charging. The average voltage that rises during charging from 08.00 to 15.00 is 0.341 V after the monitoring process.<
