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)(yang)能路(lu)燈(deng)系統可以保(bao)障陰雨天氣(qi)15天以上正常工作(zuo)！它的系統組(zu)成是(shi)由LED光(guang)源（含驅動）、太(tai)陽(yang)(yang)能電(dian)池(chi)板、蓄電(dian)池(chi)（包括蓄電(dian)池(chi)保(bao)溫箱）、太(tai)陽(yang)(yang)能路(lu)燈(deng)控(kong)制器、路(lu)燈(deng)燈(deng)桿（含基(ji)礎(chu)）及輔料(liao)線材(cai)等幾部分構成 [1]  。

太(tai)陽(yang)能電(dian)(dian)池(chi)(chi)(chi)組件(jian)一(yi)般(ban)(ban)選(xuan)用單晶(jing)硅或者多(duo)晶(jing)硅太(tai)陽(yang)能電(dian)(dian)池(chi)(chi)(chi)組件(jian)；LED燈(deng)(deng)頭一(yi)般(ban)(ban)選(xuan)用大功(gong)率LED光源(yuan)；控(kong)(kong)制(zhi)(zhi)(zhi)器(qi)一(yi)般(ban)(ban)放置在燈(deng)(deng)桿內，具有(you)光控(kong)(kong)、時控(kong)(kong)制(zhi)(zhi)(zhi)、過(guo)充(chong)過(guo)放保(bao)(bao)護(hu)及反接保(bao)(bao)護(hu)，更(geng)高級(ji)的(de)控(kong)(kong)制(zhi)(zhi)(zhi)器(qi)更(geng)具備四季調整(zheng)亮燈(deng)(deng)時間功(gong)能、半功(gong)率功(gong)能、智(zhi)能充(chong)放電(dian)(dian)功(gong)能等(deng)；蓄電(dian)(dian)池(chi)(chi)(chi)一(yi)般(ban)(ban)放置于地下或則會有(you)專門的(de)蓄電(dian)(dian)池(chi)(chi)(chi)保(bao)(bao)溫箱，可(ke)采用閥控(kong)(kong)式鉛酸蓄電(dian)(dian)池(chi)(chi)(chi)、膠體蓄電(dian)(dian)池(chi)(chi)(chi)、鐵鋁蓄電(dian)(dian)池(chi)(chi)(chi)或者鋰電(dian)(dian)池(chi)(chi)(chi)等(deng)。太(tai)陽(yang)能燈(deng)(deng)具全自動工作，不需要(yao)挖溝布線(xian)，但(dan)燈(deng)(deng)桿需要(yao)裝置在預埋件(jian)（混凝(ning)土底座(zuo)）上(shang)。
