低鐵(tie)超(chao)白(bai)就(jiu)是(shi)說光(guang)(guang)伏(fu)組(zu)件(jian)中光(guang)(guang)伏(fu)玻(bo)璃(li)的(de)含鐵(tie)量比普通(tong)(tong)玻(bo)璃(li)要(yao)低，光(guang)(guang)伏(fu)組(zu)件(jian)廠(chang)，從而增加(jia)了(le)玻(bo)璃(li)的(de)透光(guang)(guang)率(lv)。同時從玻(bo)璃(li)邊(bian)緣看(kan)(kan)，這種(zhong)玻(bo)璃(li)也(ye)比普通(tong)(tong)玻(bo)璃(li)白(bai)，普通(tong)(tong)玻(bo)璃(li)從邊(bian)緣看(kan)(kan)是(shi)偏綠(lv)色的(de)。光(guang)(guang)伏(fu)組(zu)件(jian)的(de)正(zheng)負極在接(jie)(jie)線(xian)盒內與設(she)計好的(de)電纜相連接(jie)(jie)，與外(wai)部線(xian)路連接(jie)(jie)。接(jie)(jie)線(xian)盒具有(you)如下(xia)幾個主要(yao)特(te)性(xing)：1.光(guang)(guang)伏(fu)組(zu)件(jian)接(jie)(jie)線(xian)盒外(wai)殼(ke)具有(you)強(qiang)烈的(de)抗老化、耐紫外(wai)線(xian)能力；2.光(guang)(guang)伏(fu)組(zu)件(jian)接(jie)(jie)線(xian)盒符(fu)合(he)室外(wai)惡劣環境條件(jian)下(xia)的(de)使(shi)用要(yao)求。

光(guang)(guang)伏(fu)組件(jian)(jian)(jian)(jian)必須有(you)框(kuang)架(jia)，以保護組件(jian)(jian)(jian)(jian)、方(fang)便組件(jian)(jian)(jian)(jian)的(de)(de)連(lian)接和(he)固定。光(guang)(guang)伏(fu)組件(jian)(jian)(jian)(jian)框(kuang)架(jia)的(de)(de)主要材料有(you)不銹鋼(gang)、鋁合金(jin)、橡膠及增強塑料等。常規光(guang)(guang)伏(fu)框(kuang)架(jia)一(yi)(yi)般是(shi)鋁材料制作的(de)(de)。光(guang)(guang)伏(fu)組件(jian)(jian)(jian)(jian)的(de)(de)主要原材料：光(guang)(guang)伏(fu)玻(bo)璃。電池組件(jian)(jian)(jian)(jian)采用的(de)(de)面板玻(bo)璃是(shi)低鐵(tie)超白絨(rong)面鋼(gang)化玻(bo)璃。一(yi)(yi)般厚度為3．2mm和(he)4mm，建材型太(tai)陽能電池組件(jian)(jian)(jian)(jian)有(you)時要用到5~10mm厚度的(de)(de)鋼(gang)化玻(bo)璃，煙臺光(guang)(guang)伏(fu)組件(jian)(jian)(jian)(jian)，但無(wu)論厚薄都要求透光(guang)(guang)率(lv)在90％以上。

太(tai)(tai)(tai)(tai)陽(yang)(yang)能(neng)(neng)電(dian)(dian)池(chi)(chi)組件(jian)的(de)作用是(shi)將太(tai)(tai)(tai)(tai)陽(yang)(yang)能(neng)(neng)轉化(hua)為電(dian)(dian)能(neng)(neng)，或(huo)送往蓄電(dian)(dian)池(chi)(chi)中存(cun)儲起(qi)來，或(huo)推動負(fu)載工(gong)作。對正負(fu)電(dian)(dian)荷(he)，由于在PN結區(qu)域的(de)正負(fu)電(dian)(dian)荷(he)被分(fen)離，光(guang)伏(fu)組件(jian)生產(chan)廠家，因而可以產(chan)生一個(ge)外電(dian)(dian)流(liu)場，光(guang)伏(fu)組件(jian)廠家，電(dian)(dian)流(liu)從晶(jing)體硅(gui)(gui)片電(dian)(dian)池(chi)(chi)的(de)底端經(jing)過負(fu)載流(liu)至電(dian)(dian)池(chi)(chi)的(de)頂端。 這(zhe)就是(shi) “光(guang)生伏(fu)打效應(ying)”。多晶(jing)硅(gui)(gui)太(tai)(tai)(tai)(tai)陽(yang)(yang)能(neng)(neng)電(dian)(dian)池(chi)(chi)的(de)使用壽命也要比單晶(jing)硅(gui)(gui)太(tai)(tai)(tai)(tai)陽(yang)(yang)能(neng)(neng)電(dian)(dian)池(chi)(chi)短(duan)。從性能(neng)(neng)價格比來講(jiang)，單晶(jing)硅(gui)(gui)太(tai)(tai)(tai)(tai)陽(yang)(yang)能(neng)(neng)電(dian)(dian)池(chi)(chi)還(huan)略好(hao)。太(tai)(tai)(tai)(tai)陽(yang)(yang)能(neng)(neng)電(dian)(dian)池(chi)(chi)板的(de)輸(shu)出功率應(ying)為555Wh/6h/70%=130W。其中70%是(shi)充電(dian)(dian)過程中，太(tai)(tai)(tai)(tai)陽(yang)(yang)能(neng)(neng)電(dian)(dian)池(chi)(chi)板的(de)實際使用功率。
