臺灣博碩士論文加值系統

截至2016年底全球太陽能累積安裝量已超過300GW，而台灣政府預期至2025年將造就國內17GW安裝量的地面型太陽能發電系統。綜觀過去在台灣的文獻研究，並沒有特別針對地面型太陽能發電系統做深入的投資效益分析。本研究旨在利用最新資訊與實際案例，對台灣地面型太陽能發電系統進行投資效益分析的探討，以供太陽能發電業者未來對案場選址、風險評估、投資效益以及日後營運成本分析上有所幫助。

本研究以裝置容量為498.22kw之台灣地面型太陽能發電系統為研究對象，利用淨現值、內部報酬率與還本期間法等主要投資效益指標進行投資效益分析。而實證結果顯示，地面型太陽能發電系統在目前台灣的投資環境下具有顯著的投資效益；在3%折現率配合七成銀行融資條件下，淨現值為12,457,606元，內部報酬率得到14.02%與7.26年較短的還本期間。

另外在相當地理位置情況下，本研究對比相同安裝容量的屋頂型太陽能發電系統投資項目。經實證分析結果得知，地面型太陽能發電系統即使初始建置成本較高，但其具有較高的單位發電量、不降反升的躉購價格、較低的太陽能發電系統租金成本及較低的維運成本等優勢下，地面型太陽能發電系統的投資效益反而比傳統的屋頂型太陽能發電系統具有較高的投資效益。

本研究將影響投資效益的變數利用正負10%、20%變動率，去做投資效益敏感度分析，並探討其投資效益指標淨現值、內部報酬率與還本期間的變化。實證結果得知，其投資風險影響程度由高至低排列分別為1.系統建置成本2.單位發電效率3.系統維運成本4.太陽能系統保險費5.太陽能案場租金。本研究最後再將研究結果，歸納分析整理成具體的結論與建議，希望能對未來相關學者與業者有實質幫助。

As of the end of 2016, the installed capacity of global solar energy has more than 300GW, and the Taiwan government is expected to create 17GW installation of ground mounted solar power system before 2025. From the perspective of research in the past, there is no specific investment benefit analysis for ground mounted solar power system in Taiwan. This research aims to use the latest information and practical examples for solar industry to do the investment benefits analysis of ground mounted solar power system in Taiwan, and help for solar power companies in the future on site selection, risk assessment, investment benefits and operating costs.

In this research, the investment benefits analysis was carried out by using the main investment benefit index of net present value, internal rate of return and payback period based on a capacity of 498.22kw of ground mounted solar power system in Taiwan. The research results show that the ground mounted solar power system has significant investment benefit in the current investment environment in Taiwan. With 70% of bank financing, the net present value is NTD12,457,606 at 3% discount rate, and also got 14.02 % of the internal rate of return and 7.26 years of payback period.

In addition, in the consideration of similar geographical location, this research compared the same installation capacity of roof-type solar power system investment projects. Even if the initial construction cost of ground-mounted solar power system is higher, the research results show that the ground-mounted solar power system has better investment benefits than the roof-type solar power system. This is because ground-mounted solar power system has a higher power generation efficiency, a higher FIT rate, a lower rent fee and a lower maintenance cost.

This study used plus and minus 10%, 20% rate of investment benefit variables to analyze the influences of the net present value, the internal rate of return and the payback period. The results show that the degree of investment risk impact from high to low are 1.System costs 2.power generation efficiency 3.System maintenance costs 4. Solar system insurance 5. Power plant rent. Finally, the research results are summarized into concrete conclusions and suggestions. I hope that this research will be helpful for related researchers and solar companies in the future.
