A DESIGN OF A SOLAR PHOTOVOLTAIC POWER GENERATION SYSTEM AND REAL-TIME PERFORMANCE MONITORING SYSTEM USING IoT TECHNOLOGY

Abstract

This article presented the design of a solar photovoltaic power generation system and real-time performance monitoring system using IoT technology. The primary objective was to design and develop a solar-power generation system equipped with a real-time monitoring system of energy consumption as well as to evaluate the efficiency of the performance monitoring system. The monitoring system was designed to measure voltage, electrical current and power, including various constraints, for examples; maximum current, installed power capacity, and load percentage. All data would be displayed on a smartphone using the Blynk application, allowing users to monitor the status of system as real time. The system design was also emphasized on a stable operation and accurate measurement of electrical current. The research results were indicated that the average error of electrical current measurement was 0.99%, while the average error of voltage measurement was 0.15%, demonstrating high accuracy. The system was tested in real-situation applications by supplying power to an insect-repellent lighting system used in agriculture. The test results showed that the solar photovoltaic power generation system could provide sufficient energy covering the operational period of the load. Furthermore, the performance monitoring system of electrical-power generation enabled users to verify power-generation capabilities and evaluate capacity of system efficiently. It also helped users to precisely plan an energy consumption based on load demand.
