[IEEE 2019 IEEE 46th Photovoltaic Specialists Conference (PVSC) - Chicago, IL, USA (2019.6.16-2019.6.21)] 2019 IEEE 46th Photovoltaic Specialists Conference (PVSC) - Fight Climate Change (Global Warming) With Solar + Multi-Storage Resilient Smart Home/Building And Ensure Security & Safety While Saving Thousands

摘要： Using industrial IoT smart devices for home/building automation, energy usage monitoring & control and sky-camera with local satellite/radar imaging for weather forecasting we achieved a smart energy management system that can control and balance the home/building energy ecosystem and reduce the carbon footprint by 92%. Grid-buy electricity from the utility was reduced from 14.5MWh/year costing $4,754/year to 1.2MWh/year costing $371/year for a return on investment of <3.1 years. Using multiple renewable energy storage techniques (battery, hot and cold thermal storage) we reduced the overnight energy usage from 70% to 25% which was satisfied by battery and thermal storage device discharge. We achieved Island Nano-Grid and 100% renewable clean energy for resilience, security, safety and savings.
