導致價(jia)格(ge)差異的來(lai)源：LED燈(deng)具、光伏板、蓄電(dian)池。

1、客戶問(wen)“6米太陽能路燈(deng)多少錢(qian)？”

有(you)企業(ye)報價(jia)600，有(you)企業(ye)報價(jia)900。

原因：沒有(you)統(tong)一的參數要(yao)求(qiu)。

2、客戶問“6米太陽能路燈(deng)，光(guang)源30W、光(guang)伏(fu)板80W、鋰電池12V30ah，多少(shao)錢？”

有企(qi)業(ye)報(bao)價(jia)600，有企(qi)業(ye)報(bao)價(jia)900。

原(yuan)因：報(bao)的偷工減料了(le)！雖然限(xian)制(zhi)了(le)參數，但為(wei)(wei)了(le)爭取業務，部分(fen)企業會按30W-70W-3.2V30ah或其它標(biao)準(zhun)交貨。（注意鋰(li)電池(chi)系統的電壓(ya)、鋰(li)電池(chi)電芯是(shi)否(fou)為(wei)(wei)拆機、燈桿的口徑厚度及是(shi)否(fou)為(wei)(wei)整體熱(re)鍍(du)鋅）

3、客戶問“6米太陽能路燈，光(guang)源150W、光(guang)伏板200W、鋰電池300ah，多少(shao)錢？”

這樣的路(lu)燈，正規企業都(dou)不會報價，終成交的一定是小企業，但會是大利(li)潤。此參(can)數配置明顯偏高，且不合(he)理。給(gei)善(shan)于偷工(gong)減料(liao)的企業，留了很大的想象空(kong)間(jian)和利(li)潤空(kong)間(jian)。

太(tai)(tai)陽(yang)能路燈(deng)市場亂象叢生，80﹪的(de)產品是不合格(ge)的(de)，沒有按照合同標(biao)準制造。主要(yao)原因(yin)是，太(tai)(tai)原太(tai)(tai)陽(yang)能路燈(deng)工程，LED燈(deng)具的(de)功率(lv)、光伏板的(de)瓦數、蓄(xu)電池的(de)容(rong)量(liang)，一(yi)般(ban)客戶無法檢測，使偷(tou)工減料有機可乘，價(jia)格(ge)競爭高低不一(yi)。

以上價(jia)(jia)格(ge)均為舉例，實(shi)際價(jia)(jia)格(ge)咨詢客(ke)服 根據不同時間市(shi)場(chang)的材料價(jia)(jia)格(ge)而(er)決定。

   太陽能路燈(deng)光伏效應基本原理介紹

太(tai)陽(yang)能(neng)路燈是利用光(guang)生(sheng)伏(fu)應原理制(zhi)成的太(tai)陽(yang)能(neng)電(dian)池白天電(dian)池板接收太(tai)陽(yang)輻射能(neng)并轉化(hua)為電(dian)能(neng)輸(shu)出，光(guang)生(sheng)伏(fu)應是指(zhi)半導體在受到光(guang)照(zhao)射時產生(sheng)電(dian)動勢的現象。

光(guang)(guang)生(sheng)(sheng)伏應(ying)簡稱光(guang)(guang)伏效應(ying)，太原太陽能(neng)(neng)路(lu)燈廠家地址，風光(guang)(guang)互補(bu)控制器指光(guang)(guang)照使不均勻半(ban)導(dao)體(ti)或(huo)半(ban)導(dao)體(ti)與金(jin)屬結合的不同部位(wei)之間產生(sheng)(sheng)電位(wei)差(cha)的現象。它首(shou)先是由光(guang)(guang)子(zi)(光(guang)(guang)波)轉化為電子(zi)、光(guang)(guang)能(neng)(neng)量轉化為電能(neng)(neng)量的過程(cheng);其次，是形成電壓過程(cheng)。有了(le)電壓，就像筑(zhu)高(gao)了(le)大壩，如果兩者之間連通，就會形成電流的回(hui)路(lu)。

如果光(guang)(guang)線照射在(zai)(zai)(zai)(zai)(zai)太(tai)陽(yang)能(neng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)上并(bing)且光(guang)(guang)在(zai)(zai)(zai)(zai)(zai)界(jie)(jie)(jie)面(mian)層(ceng)(ceng)被(bei)吸收，具有足夠(gou)能(neng)量的光(guang)(guang)子能(neng)夠(gou)在(zai)(zai)(zai)(zai)(zai)P型硅(gui)和N型硅(gui)中將電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子從(cong)共價鍵中激發，以致(zhi)產生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子-空(kong)穴(xue)對。界(jie)(jie)(jie)面(mian)層(ceng)(ceng)附近的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子和空(kong)穴(xue)在(zai)(zai)(zai)(zai)(zai)復合之前(qian)，將通(tong)過(guo)(guo)空(kong)間(jian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)作用被(bei)相互分離。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子向帶正電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的N區和空(kong)穴(xue)向帶負電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的P區運動。通(tong)過(guo)(guo)界(jie)(jie)(jie)面(mian)層(ceng)(ceng)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷分離，將在(zai)(zai)(zai)(zai)(zai)P區和N區之間(jian)產生一個(ge)向外的可測試(shi)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)。此時可在(zai)(zai)(zai)(zai)(zai)硅(gui)片的兩邊加上電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極并(bing)接入電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)表。對晶(jing)體硅(gui)太(tai)陽(yang)能(neng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)來說，開路(lu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)的典型數值(zhi)為0.5～0.6V。通(tong)過(guo)(guo)光(guang)(guang)照在(zai)(zai)(zai)(zai)(zai)界(jie)(jie)(jie)面(mian)層(ceng)(ceng)產生的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子-空(kong)穴(xue)對越(yue)多，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流越(yue)大。界(jie)(jie)(jie)面(mian)層(ceng)(ceng)吸收的光(guang)(guang)能(neng)越(yue)多，界(jie)(jie)(jie)面(mian)層(ceng)(ceng)即(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)面(mian)積越(yue)大，在(zai)(zai)(zai)(zai)(zai)太(tai)陽(yang)能(neng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)中形成的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流也(ye)越(yue)大。
