摘要
本研究針對國內接受政府第二期太陽能熱水系統推廣獎勵工作中第一年(西元2000年)安裝之所有用戶,於2012年間進行使用現況普查工作,藉此瞭解這些已使用太陽能熱水器超過10年以上的用戶,對於所安裝太陽能熱水器的第一手使用經驗。由於用戶資料及所安裝使用之太陽能熱水器產品資料,皆已於申請補助作業中建檔管理,本次普查作業的成功受訪率高達52.3%,且可信度極高。本研究發現2000年安裝使用之家用太陽能熱水器的損壞率僅有3%,推算其使用壽命較一般市場經驗所言的15~20年更為樂觀。至於到2012年調查期間為止仍在使用2000年所購置太陽能熱水器的用戶,則約有半數的用戶曾經維修過系統,且以加熱器汰換、管路耗損的情況最為常見。在整體滿意度及未來續購意願的部分,分別有79.6%及82.0%的用戶表達正面回饋意見,顯示民眾對於太陽能熱水器具備高度的使用信心。這些數據除能作為台灣太陽能熱水器市場輪廓和使用狀況的描述之外,更可提供政府未來制訂太陽熱能政策,以及廠商經營策略之參考資訊。

A general survey on the utilization status of solar water heaters (SWHs) installed in the year of 2000, which was the first year of the second phase of SWH subsidy program launched by Taiwan government, was conducted in 2012. The purposes of this general survey are twofold. First is to understand the utilization status of these SWHs. Next is to collect the user experiences of these installed SWHs. The successful interview rate is as high as 52.3% since the complete user database has been established in the subsidy application process. Thus, the confidence level on this survey is quite high. It was found from the survey that only about 3% of the SWHs installed in 2000 were out of service, which is more optimistic as comparing to the 15-20 years of life cycle estimated by the domestic SWH industry. However, 53.3% of the in-service SWHs have ever experienced malfunctions. Among the malfunctions, damage to the electric auxiliary heating rod (37.8%), pipeline leakage (17.5%), and malfunction of timer/control panel/temperature sensor (15.7%) are the main causes. The satisfaction rate for the installed SWHs is 79.6%. As far as the consumer dissatisfaction is concerned, no hot water on rainy days or in winter (39.8%) and high electricity consumption (24.8%) are two main reasons. The willingness to renew a SWH in the future is as high as 82.0%. The survey results present the market status of the SWHs installed in 2000, and a valuable reference to both government and domestic SWH industry for setting up either the future promotion policy or marketing strategy.
