太陽能路燈是采用晶體硅太陽能電池供電，免維護閥控式密封蓄電池（膠體電池）儲存電能，超高亮LED燈具作為光源，并由智能化充放電控制器控制，用于代替傳統公用電力照明的路燈。

太(tai)陽(yang)能(neng)路燈(deng)系(xi)統(tong)可以保(bao)障(zhang)陰雨天(tian)氣15天(tian)以上正常工(gong)作！它的系(xi)統(tong)組成是(shi)由LED光源（含驅(qu)動）、太(tai)陽(yang)能(neng)電(dian)池板(ban)、蓄電(dian)池（包(bao)括蓄電(dian)池保(bao)溫箱）、太(tai)陽(yang)能(neng)路燈(deng)控制器、路燈(deng)燈(deng)桿（含基礎）及輔料線材(cai)等(deng)幾部分構成 [1]  。

太陽(yang)能(neng)(neng)(neng)電(dian)(dian)(dian)池(chi)組(zu)件(jian)一般(ban)選用單晶硅或(huo)者多(duo)晶硅太陽(yang)能(neng)(neng)(neng)電(dian)(dian)(dian)池(chi)組(zu)件(jian)；LED燈頭一般(ban)選用大功(gong)(gong)率LED光源(yuan)；控(kong)(kong)制(zhi)器(qi)一般(ban)放置在(zai)燈桿內，具(ju)有(you)光控(kong)(kong)、時(shi)控(kong)(kong)制(zhi)、過充過放保(bao)護(hu)及反接保(bao)護(hu)，更(geng)高級的(de)控(kong)(kong)制(zhi)器(qi)更(geng)具(ju)備四季(ji)調(diao)整亮燈時(shi)間功(gong)(gong)能(neng)(neng)(neng)、半功(gong)(gong)率功(gong)(gong)能(neng)(neng)(neng)、智(zhi)能(neng)(neng)(neng)充放電(dian)(dian)(dian)功(gong)(gong)能(neng)(neng)(neng)等；蓄電(dian)(dian)(dian)池(chi)一般(ban)放置于地下(xia)或(huo)則會有(you)專門的(de)蓄電(dian)(dian)(dian)池(chi)保(bao)溫(wen)箱(xiang)，可采用閥控(kong)(kong)式鉛酸(suan)蓄電(dian)(dian)(dian)池(chi)、膠體蓄電(dian)(dian)(dian)池(chi)、鐵鋁蓄電(dian)(dian)(dian)池(chi)或(huo)者鋰電(dian)(dian)(dian)池(chi)等。太陽(yang)能(neng)(neng)(neng)燈具(ju)全自(zi)動(dong)工(gong)作，不需(xu)要(yao)挖溝布(bu)線，但(dan)燈桿需(xu)要(yao)裝置在(zai)預埋件(jian)（混(hun)凝土底座）上。
