摘要

依能源局統計台中地區已增太陽光電的業主回報日照時數值為3.5 KWh／day／KWp，計算屋頂太陽光電模組發一年每KW發電度數1,278度／KWp。依台中氣象站10年統計的最低日照時數值為4.92hr／每日，計算屋頂太陽光電模組發一年每KW發電度數1,437度／KWp。依台中氣象站10年統計年日照射量方式計算，全年日照射量值為1,526.19KWh／㎡。以三種計算模式的發電量每年遞減10%，以每年本金攤還為1,071,429元，貸款利率3.5%，20年內部報酬率IRR：各縣市回報能源局計算模式為14.27%＜日照時數計算模式89.22%＜日照射量計算模式172%。日照射量計算模式的發電量20年其期間營業收入為50,314,329元，淨現值為5,515,404元，第一年現金流量為46,050元，且14年貸款其期間現金流量為1,861,535元，20年其期間現金流量為9,315,893元。日照時數（系統直流發電比）計算模式的發電量20年其期間營業收入為48,847,243元，淨現值為4,640,210元，第一年現金流量為-20,822元，且14年貸款其期間現金流量為983,820元，20年其期間現金流量為8,098,212元。各縣市回報能源局計算模式的發電量20年其期間營業收入為45,097,904元，淨現值為2,403,531元，且14年貸款其期間現金流量為-1,448,272，20年其期間現金流量為4,986,261元。高階經營者若以風險管理觀點來探討，且以風險的關鍵因素相同，何種？計算模式的發電量較合理且可行。以採用該地區十年統計每日的最低日照時數為4.92較合理穩健。

According to the Energy Bureau statistics Taichung area has been increased solar photovoltaic owners sunshine returns a value of 3.5 KWh/day/KWp, calculate roof type photovoltaic modules made of each year by generating 1,278 KW/ KWp. According to the minimum value Taichung sunshine weather statistics for 10 years 4.92hr/ day, calculated roof type photovoltaic modules made of each year by generating 1,437 KW/ KWp. Calculated according to weather 10 years from the date Taichung Statistical exposure mode, the annual day of irradiation values 1,526.19 KWh/m^2. Calculation mode in three power generation capacity decreasing by 10% per year ,with annual principal amortization of NT 1,071,429, the loan interest rate of 3.5% ,internal rate of return IRR 20 years: Each county Board of return calculation mode 14.27% Energy Agency ＜ sunshine calculation mode 89.22% ＜ days exposure calculation mode 172%. Daily exposure calculation mode of generating capacity during its 20-year operating income of NT 50,314,329, the Net PresentValue (NPV) of NT 5,515,404, the first-year cash flow NT 46,050, and the 14-year loan during its cash flow NT 1,861,535, 20 years during which cash flow NT 9,315,893. Sunshine hours (System DC power ratio) calculation mode of power generation during its 20-year operating income of NT 48,847,243, the Net PresentValue (NPV) of NT 4,640,210, the first-year cash flow NT -20,822, and 14-year loans to its cash flow for the period NT 983,820, the cash flow for 20 years during which to NT 8,098,212 yuan. Each county Board of return calculation mode energy generating capacity during its 20-year operating income of NT 45,097,904, the Net PresentValue (NPV) of NT 2,403,531, and the 14-year loan during its cash flow NT-1,448,272, during which 20-year cash flow NT 4,986,261. CEO In terms of risk management perspective to explore and to key risk factors are the same, what? Generation calculating model is reasonable and feasible. In using the statistical area ten year minimum daily sunshine hours for 4.92 more reasonable acceptable.
