太陽能庭院燈以太陽輻射能為能源,白天利用太陽能電池板給蓄電池充電,晚上蓄電池給庭院燈光源供電使用,無需復雜昂貴的管線鋪設,可任意調整燈具的布局,安全節能無污染,充電及開/關過程采用智能控制,光控自動開關,無需人工操作,工作穩定可靠,節省電費,免維護。
太陽能(neng)庭院燈(deng)(deng)(deng)照明采用(yong)(yong)功(gong)率相當于(yu)70W白熾燈(deng)(deng)(deng)亮度的CCFL無機燈(deng)(deng)(deng)管,燈(deng)(deng)(deng)柱高(gao)3m,燈(deng)(deng)(deng)管壽(shou)命大于(yu)20000小時(shi);電(dian)(dian)(dian)源采用(yong)(yong)35w單晶硅太陽能(neng)電(dian)(dian)(dian)池(chi)板(ban),光(guang)控定時(shi)開關(guan)。質(zhi)量(liang)保證(zheng)期25年(nian),25年(nian)后電(dian)(dian)(dian)池(chi)組件能(neng)繼續(xu)使(shi)用(yong)(yong),但(dan)發電(dian)(dian)(dian)量(liang)略有下降。發電(dian)(dian)(dian)系統具有抗(kang)臺風、抗(kang)潮濕(shi)、抗(kang)紫外線輻射等特(te)點(dian)。系統可以(yi)在(zai)一40℃~70℃環境下確(que)保日工作(zuo)時(shi)間4~6小時(shi);如遇連續(xu)陰雨天(tian)數(shu),將平時(shi)多(duo)余的電(dian)(dian)(dian)能(neng)儲存(cun)在(zai)蓄(xu)電(dian)(dian)(dian)池(chi)內,可確(que)保用(yong)(yong)戶在(zai)陰雨天(tian)氣連續(xu)2~3天(tian)仍有足夠的電(dian)(dian)(dian)源可以(yi)正常使(shi)用(yong)(yong)。每盞(zhan)太陽能(neng)庭院燈(deng)(deng)(deng)的成本為(wei)3000~4000元。將光(guang)伏庭院燈(deng)(deng)(deng)與普(pu)通庭院燈(deng)(deng)(deng)進(jin)行分析比(bi)較(jiao):光(guang)伏庭院燈(deng)(deng)(deng)初裝價(jia)為(wei)普(pu)通庭院燈(deng)(deng)(deng)的120%~136%,使(shi)用(yong)(yong)兩年(nian)后兩者綜合成本基(ji)本持平。
