摘要: | 太陽光電系統之設置形式基本上分為固定式、單軸追日式與雙軸追日式等,不同設置型式之系統發電產量皆有顯著之差異。其中,固定式系統之太陽能模組設置傾斜角也會影響系統輸出效能。關於上述不同設置條件之系統發電量評估,在產學界上一直是個令人感到興趣的議題、其量化數值卻尚無完整理論之分析與支持。在本論文中,首先以半導體理論基礎建立了太陽能電池模型,探討其太陽入射角度、電氣參數與發電效能之關係;進一步套用此模型並整合太陽運動軌跡演算法於各不同設置形式之光電系統,並進行長時間之實驗佐證,可有效與精確地估算各不同系統之年發電產量。最後,應用此演算法則提出一項改良型太陽光電系統之設計,應用於國內溫、網室等農業設施做發電量估算,包含了不同斜度屋頂型態之設施;並進一步分析減碳效益與附加經濟效益評估,可提供國內農業主管機關、溫網室農民業者與光電系統業者,客觀與量化之研究數據,達成兼顧農地農用與綠能種電雙贏的目標。 The construction type of photovoltaic (PV) systems contains the fixed-type (FT), the single-axis tracking type (SASTT) and the dual-axis tracking type (DASTT) systems. The energy harvested by each type of PV systems are significant different. In addition to the effect of the types of PV systems, the tilt angle of a PV module that includes an FT system also affects the output power of the module. The assessment of energy harvested by different construction conditions of PV systems is an interesting topic in the PV industry and academia, but there is no comprehensive theory to support the quantitative numerical analysis of the assessment. In this study, a theoretical model of PV modules was first established to investigate the relationship between the performance of PV modules, and the solar incident angle and the electrical parameters. Furthermore, this model integrated with the solar trajectory on various construction types of PV systems. The long-term experimental results show that the proposed model can effectively and accurately evaluate the annual energy harvested by the PV systems. Finally, an improved PV system design was proposed, which can be applied to agricultural facilities for energy harvested assessment, such as greenhouses and screenhouses. The proposed method can also provide objective and quantitative information for agricultural authorities, owners of agricultural facilities, and PV system installers about the carbon reduction and additional economic benefits to achieve a win-win outcome for all parties. |
