IoT-based solar cell power supply design and analysis at the Assyifa Islamic boarding school laboratory, Subang Regency, West Java as an environmentally friendly green energy

With the development of Internet of things (IoT) technology, as well as a well-integrated solar energy source that can be operated, monitored, controlled remotely as a technology that continues to be developed. The design of an IoT- based solar energy system for PLTS at the Assyifa Islamic Boarding School Laboratory in Subang Regency as an active contribution to dealing with air pollution as well as renewable energy solutions and handling air pollution as well as solutions for the current depletion of fossil energy sources. The system is planned with solar panels, inverter and electric current controller, which has built-in WiFi connectivity. Solar panels and other devices provide the necessary operating power, sensor controllers mounted on solar panels, irradiant, power distribution panels as well as electricity production and loads that are monitored at the research site points. The PV Syst 7.2.8 design simulator is used to compare the use of 4 combination options from 2 brands of Solar Panels and 2 brands of Inverters for the capacity of PLTS On-Grid 2025Wp. Utilization of building roofs or vacant land for solar power generation is an effective and efficient solution. This study is to compare 4 combination models and see the feasibility of the performance and economic value, calculate the average return on investment under 10 years which produces electrical energy of 4.23kwh/kwp/day and refers to the warranty period for the solar panels themselves. Indonesia is located on the equator and has the availability of sunlight throughout the year.
