研究目的
To achieve a smart energy management system that can control and balance the home/building energy ecosystem and reduce the carbon footprint by 92% using industrial IoT smart devices for home/building automation, energy usage monitoring & control and sky-camera with local satellite/radar imaging for weather forecasting.
研究成果
The study demonstrated that using industrial IoT smart devices and a smart energy management system can significantly reduce the carbon footprint and achieve 100% renewable clean energy for resilience, security, safety, and savings. The system achieved a return on investment of <3.1 years and reduced grid-buy electricity usage by 92%.
研究不足
The study's results are based on a specific case study in Hawaii, and the effectiveness of the system may vary in different geographical locations and climates. Additionally, the initial investment cost for the system may be a barrier for widespread adoption.
1：Experimental Design and Method Selection:
The study utilized a 7kW, 27-panel cSi rooftop solar PV system with a Tabuchi Electric hybrid solar inverter and embedded
2：8kWh Panasonic Li-ion dual-battery. Hot water thermal storage was achieved with 3 solar thermal panels to super charge the 120 gallon hot water storage tank. Sample Selection and Data Sources:
The rooftop solar energy system was installed on June 1, 2016, and data was collected over a
3：5 year period. List of Experimental Equipment and Materials:
Included a rooftop solar PV system, solar thermal panels, hot water storage tank, and IoT smart devices for monitoring and controlling.
4：Experimental Procedures and Operational Workflow:
The system underwent several upgrades and improvements over the study period to improve total solar system energy production and storage.
5：Data Analysis Methods:
The study analyzed the system's performance in reducing grid-buy electricity usage and utility bills, and achieving 100% renewable clean energy.
