摘要:	本研究主要目的在於探討國內建築用太陽能光電板饋電價格之策略，對於國內再生能源發展條例中，有關建築用併聯型太陽能光電板系統所產生之回饋電力，以適當饋電價格收購。本研究以國外先進國家再生能源饋電(Feed in Tariffs)的施行，擴大建築裝置容量的經驗為基礎。以假設條件建構國內建築應用太陽能光電板饋電效益計算模型，經國內實際監控個案的數據驗證此計算模型，用財務分析方法分析監控個案的淨現值與投資報酬率。再經敏感性分析，探討建築應用太陽能光電板(PV)個案計算各種饋電價格與補助金額後的成本效益及回收年限。輔以經濟部能源局97年度補助案例，計算分析國內北部、中部與南部一般住宅和企業案例的饋電差異並分析其成本結構與結果，太陽能光電板模組的價格趨勢、裝置容量大小與饋電價格的關係。研究結果顯示: 一、北部、中部與南部設置太陽能光電板案例中，回收年限有顯著的差異。二、在現行補助獎勵條件下，企業用戶設置成本優於一般住宅用戶。三、饋電價格採合理內部投資報酬率公式計算。四、饋電價格考量裝置容量及單位(KWp)設置成本，饋電價格應相對調整。 Feed-in tariffs (FITs) have been an important part of successful renewable energy policy packages in many countries. This study proposed the practical strategies implementing FITs for building integrated photovoltaic (BIPV) in Taiwan. The purchase rates for solar photovoltaics renewable electricity were derived. The related experiences of FITs programs in some advanced countries have first been reviewed to determine the variables for modeling. The experimental data have been collected from many sites in Taipei to provide a set of reasonable parameters assuming the FITs scheme will be available. The final results were presented by some common financial metrics such as net present value (NPV), internal ratio of return (IRR) and payback period. Sensitivity analysis were also conducted to demonstrate the impacts from a variety of conditions such as location, PV installed size in Taiwan’s grid-connected systems, residential vs. commercial case. The research concludes: 1. Payback periods vary from case to case with location, residential and commercial cases. 2. Residential FIT is higher than commercial ones at the same subside level due to advantages in tax credit. 3. FIT scheme should be implemented with reasonable IRR. 4. Tariff rates should be adjusted based on the installed capacity and unit cost.
