摘要: 太陽能熱水系統為太陽熱能最普及之應用，政府自1987年開始歷經兩期對太陽能熱水系統之補助，安裝普及率已達總戶口數之4.13%，其中金門縣政府自行加碼補助(2008-2019)，安裝普及率更高達11.5%。本研究針對金門縣在第二期補助期間(2000-2018年)之用戶進行普查，普查作業成功率為62.5%，其中75.4%的用戶尚在使用太陽能熱水系統。使用期間曾出現故障狀況占比為47.9%，探究其故障原因，主要是因為金門水質含相當濃度之氯鹽，在環境溫度較高時，對不鏽鋼材質具腐蝕性，易造成熱水儲桶、電熱棒及配管之損壞。對曾購置但目前不再使用太陽能熱水系統之用戶進行調查，結果顯示若能補助更換主要組件(如集熱板、儲水桶、控制器)，方有意願重新購置太陽能熱水系統。另如同太能熱能在全國之目前應用般，金門縣95.4%太陽熱能應用為家用系統，未來可朝工、商業大型系統應用方向推動，以進一步提升太陽熱能在國內能源使用上之應用成效。

Abatract: Solar heating is a mature technology, and the production of hot water using solar water heaters represents one of the most important renewable energy applications in the world. The Taiwanese government initiated two purchase-based subsidy programs (1986-1982; 2000-2018) and the national population ratio is 4.13%. The government of Kinmen County also offered financial incentives (2008-2019) and the population ratio is 11.5%. Interviews were conducted for all 4,695 end users in Kinmen County, in which 2,936 (62.5%) of them were reached. The survey showed that there are 2,187 systems (75.4%) in operation. The water quality (chlorine salt), resulting in leakage of solar collector, water storage tank, and piping, represents one of the key issues for proper system operation. When a subsidy program for the replacement of major components (solar collectors, storage tank or controller) can be issued, the end users are more willing to replace the old system at the least cost. Similar to the current national situation of solar thermal application, there are as high as 95.4% systems installed in the domestic sector of Kinmen County. Solar heating in the commercial sector represents another important domestic application in the future.
