| Summary: | 碩士 === 嘉南藥理大學 === 環境資源管理系 === 107 === In this study, we compared the electricity generated by renewable energy and the power consumed in a smart greenhouse on the campus of Chia Nan University of Pharmacy and Science. With the occupied area about 120m2, the facility mainly includes a treated sewage polishing system to recycle the wastewater for irrigation, and a vegetation system comprised of hypotonic and soil cultivation for different vegetation. An IoT (Internet of Things) based smart system for both online monitoring and control includes water quality, irrigation, indoor and outdoor environment, and power production and consumption. The energy budget analysis between both city electrical grid and solar panel units (HISG and CIGS) showed that the total electricity consumption in the facility was around two folds higher than production, which were 4,742.6 vs. 2,568.3 kWh from March, 2018 to June, 2019. The monthly electricity consumption in the facility ranged from 66.35~242.18 kWh with the highest in May, 2018. In general, electricity generated from solar panels increased in the hotter months from 32.07 kWh in Feb, 2019 to 242.18 kWh in May, 2018. Further analysis of the data also indicated that HISG was more efficient than CIGS with 20~35% differences in efficiency.
