我(wo)國(guo)光(guang)(guang)(guang)伏(fu)(fu)并網發(fa)電(dian)(dian)(dian)已經非常成熟。2013年以來，國(guo)家(jia)出臺(tai)了一系列光(guang)(guang)(guang)伏(fu)(fu)發(fa)電(dian)(dian)(dian)促進政(zheng)策(ce)，鼓勵(li)地方產業(ye)、家(jia)庭和公共建筑建設(she)(she)光(guang)(guang)(guang)伏(fu)(fu)發(fa)電(dian)(dian)(dian)設(she)(she)施。太(tai)陽(yang)能發(fa)電(dian)(dian)(dian)系統是利用太(tai)陽(yang)能電(dian)(dian)(dian)池(chi)直接將太(tai)陽(yang)能轉換成電(dian)(dian)(dian)能的(de)發(fa)電(dian)(dian)(dian)系統。家(jia)用太(tai)陽(yang)能發(fa)電(dian)(dian)(dian)系統由太(tai)陽(yang)能電(dian)(dian)(dian)池(chi)組(zu)(zu)、太(tai)陽(yang)能控制(zhi)器、蓄電(dian)(dian)(dian)池(chi)（組(zu)(zu)）組(zu)(zu)成。光(guang)(guang)(guang)伏(fu)(fu)發(fa)電(dian)(dian)(dian)的(de)主(zhu)要原理是半導體的(de)光(guang)(guang)(guang)電(dian)(dian)(dian)效應。光(guang)(guang)(guang)子(zi)(zi)照射到金(jin)屬(shu)(shu)上時，它的(de)能量可(ke)以被金(jin)屬(shu)(shu)中某個電(dian)(dian)(dian)子(zi)(zi)全(quan)部(bu)吸(xi)收(shou)，電(dian)(dian)(dian)子(zi)(zi)吸(xi)收(shou)的(de)能量足夠大，能克服(fu)金(jin)屬(shu)(shu)內部(bu)引力做功，離開金(jin)屬(shu)(shu)表面(mian)逃逸出來，成為光(guang)(guang)(guang)電(dian)(dian)(dian)子(zi)(zi)。

太(tai)陽(yang)能(neng)電(dian)池(chi)經過串聯后進行封(feng)裝(zhuang)(zhuang)(zhuang)保(bao)護可形成大面積(ji)的(de)太(tai)陽(yang)電(dian)池(chi)組件(jian)，再配合上功(gong)率控(kong)制(zhi)器等(deng)部件(jian)就形成了光伏(fu)(fu)(fu)發電(dian)裝(zhuang)(zhuang)(zhuang)置。中國是光伏(fu)(fu)(fu)發電(dian)安裝(zhuang)(zhuang)(zhuang)量增(zeng)長快(kuai)的(de)國家，2011年(nian)的(de)光伏(fu)(fu)(fu)發電(dian)安裝(zhuang)(zhuang)(zhuang)量比2010年(nian)增(zeng)長了約5倍，2011年(nian)電(dian)池(chi)產量達到20GW，約占的(de)65%。獨(du)立光伏(fu)(fu)(fu)電(dian)站包括(kuo)邊遠地區的(de)村(cun)莊供電(dian)系(xi)統，太(tai)陽(yang)能(neng)戶用電(dian)源(yuan)系(xi)統，上海光伏(fu)(fu)(fu)電(dian)站，通信信號電(dian)源(yuan)、陰極保(bao)護、太(tai)陽(yang)能(neng)路(lu)燈(deng)等(deng)各種帶有蓄電(dian)池(chi)的(de)可以獨(du)立運行的(de)光伏(fu)(fu)(fu)發電(dian)系(xi)統。

帶有(you)蓄電(dian)(dian)(dian)池的(de)(de)并網(wang)(wang)發電(dian)(dian)(dian)系統具有(you)可(ke)(ke)調度性，可(ke)(ke)以(yi)根據需要并入或退出電(dian)(dian)(dian)網(wang)(wang)，還具有(you)備用電(dian)(dian)(dian)源的(de)(de)功能(neng)，光(guang)(guang)(guang)伏(fu)電(dian)(dian)(dian)站收購，當(dang)電(dian)(dian)(dian)網(wang)(wang)因故停電(dian)(dian)(dian)時可(ke)(ke)緊急供(gong)電(dian)(dian)(dian)。太陽能(neng)光(guang)(guang)(guang)伏(fu)發電(dian)(dian)(dian)：將太陽能(neng)直(zhi)接轉化為電(dian)(dian)(dian)能(neng)的(de)(de)技(ji)術(shu)稱為光(guang)(guang)(guang)伏(fu)發電(dian)(dian)(dian)技(ji)術(shu)。太陽能(neng)取之(zhi)不盡，只(zhi)要有(you)陽光(guang)(guang)(guang)，隨(sui)時都有(you)電(dian)(dian)(dian)力。企業(ye)利(li)用建(jian)筑屋(wu)頂(ding)的(de)(de)優勢，建(jian)立了(le)可(ke)(ke)靠(kao)、無噪(zao)音的(de)(de)光(guang)(guang)(guang)伏(fu)電(dian)(dian)(dian)站，不僅發揮了(le)發電(dian)(dian)(dian)的(de)(de)作用，而(er)且增加了(le)建(jian)筑的(de)(de)美感(gan)，為企業(ye)創造(zao)了(le)效(xiao)益。我(wo)國光(guang)(guang)(guang)伏(fu)并網(wang)(wang)發電(dian)(dian)(dian)已經(jing)非(fei)常(chang)成熟。2013年以(yi)來，國家(jia)出臺了(le)一(yi)系列光(guang)(guang)(guang)伏(fu)發電(dian)(dian)(dian)促進政(zheng)策，鼓勵(li)地(di)方(fang)產業(ye)、家(jia)庭和公共(gong)建(jian)筑建(jian)設(she)光(guang)(guang)(guang)伏(fu)發電(dian)(dian)(dian)設(she)施。
