光(guang)(guang)(guang)伏發(fa)電(dian)(dian)原理(li)，15千瓦(wa)的(de)(de)(de)光(guang)(guang)(guang)伏發(fa)電(dian)(dian)大約的(de)(de)(de)多少錢，屋頂光(guang)(guang)(guang)伏發(fa)電(dian)(dian)廠家哪家好，光(guang)(guang)(guang)伏發(fa)電(dian)(dian)是利用(yong)半導體(ti)界面的(de)(de)(de)光(guang)(guang)(guang)生(sheng)伏應而將光(guang)(guang)(guang)能(neng)直接轉變為電(dian)(dian)能(neng)的(de)(de)(de)一種技(ji)術(shu)。這(zhe)種技(ji)術(shu)的(de)(de)(de)關鍵元件(jian)是太(tai)(tai)陽(yang)能(neng)電(dian)(dian)池。太(tai)(tai)陽(yang)能(neng)電(dian)(dian)池經(jing)過(guo)串聯后進行封(feng)裝保護(hu)可形(xing)成大面積的(de)(de)(de)太(tai)(tai)陽(yang)電(dian)(dian)池組件(jian)，再配合上功率控制器(qi)等部件(jian)就形(xing)成了光(guang)(guang)(guang)伏發(fa)電(dian)(dian)裝置。光(guang)(guang)(guang)伏發(fa)電(dian)(dian)的(de)(de)(de)設備(bei)其自身是不需要采用(yong)任何的(de)(de)(de)燃料(liao)的(de)(de)(de)，因而其也不會產生(sheng)任何會污(wu)染空氣的(de)(de)(de)氣體(ti)。
