太陽(yang)(yang)能路燈的配置如(ru)何計(ji)(ji)算呢？由(you)于(yu)太陽(yang)(yang)能路燈是(shi)靠太陽(yang)(yang)發電的，所以我們要曉得如(ru)何計(ji)(ji)算，我先(xian)從(cong)太陽(yang)(yang)能路燈每晚(wan)用幾電動手，只要曉得每晚(wan)的用電量(liang)，相應的才干(gan)計(ji)(ji)算出每天需(xu)求發幾電。

案例(li)：在(zai)長江中(zhong)(zhong)下游（峰值日照4H）美麗鄉村建立的(de)(de)過(guo)(guo)程中(zhong)(zhong)，裝30W LED 光源(yuan)(yuan)，每(mei)晚亮(liang)燈(deng)7個小時，保(bao)證(zheng)3-4個下雨天正(zheng)常(chang)亮(liang)燈(deng)的(de)(de)狀況下；我(wo)們先(xian)計(ji)算(suan)此配(pei)置(zhi)請(qing)求的(de)(de)用電(dian)(dian)量(liang)：30W LED光源(yuan)(yuan)，太(tai)陽能(neng)路(lu)燈(deng)上(shang)，正(zheng)常(chang)做(zuo)出(chu)12V系統(tong)，由此能(neng)夠得(de)出(chu)30W 的(de)(de)電(dian)(dian)流大(da)(da)小，30W/12V=2.5A的(de)(de)電(dian)(dian)流，如今每(mei)晚的(de)(de)耗電(dian)(dian)是(shi)2.5A*7H=17.5AH；假如沒(mei)有太(tai)陽保(bao)證(zheng)3到4個陰雨天正(zheng)常(chang)亮(liang)燈(deng)，那(nei)蓄(xu)電(dian)(dian)池(chi)(chi)(chi)的(de)(de)大(da)(da)小為17.5AH*4=70AH；但是(shi)由于太(tai)陽能(neng)路(lu)燈(deng)蓄(xu)電(dian)(dian)池(chi)(chi)(chi)存在(zai)過(guo)(guo)沖和過(guo)(guo)放(fang)(fang)維(wei)護，正(zheng)常(chang)太(tai)陽能(neng)路(lu)燈(deng)蓄(xu)電(dian)(dian)池(chi)(chi)(chi)的(de)(de)充電(dian)(dian)深(shen)度為90%，放(fang)(fang)電(dian)(dian)深(shen)度為70%，那(nei)也就(jiu)是(shi)說70AH的(de)(de)配(pei)置(zhi)是(shi)占總(zong)配(pei)置(zhi)的(de)(de)70%，蓄(xu)電(dian)(dian)池(chi)(chi)(chi)的(de)(de)真正(zheng)容量(liang)=70AH/0.7=100AH；
