我國光(guang)(guang)伏(fu)(fu)并網(wang)發電(dian)(dian)(dian)(dian)(dian)已經非常成(cheng)熟。2013年以(yi)來，光(guang)(guang)伏(fu)(fu)電(dian)(dian)(dian)(dian)(dian)站安裝(zhuang)價格，國家(jia)(jia)出臺了(le)一(yi)系列光(guang)(guang)伏(fu)(fu)發電(dian)(dian)(dian)(dian)(dian)促進政策，鼓(gu)勵地方產業、家(jia)(jia)庭和公(gong)共建筑(zhu)建設(she)光(guang)(guang)伏(fu)(fu)發電(dian)(dian)(dian)(dian)(dian)設(she)施。太陽(yang)能(neng)(neng)發電(dian)(dian)(dian)(dian)(dian)系統(tong)是(shi)利用(yong)太陽(yang)能(neng)(neng)電(dian)(dian)(dian)(dian)(dian)池直接(jie)將太陽(yang)能(neng)(neng)轉換成(cheng)電(dian)(dian)(dian)(dian)(dian)能(neng)(neng)的(de)發電(dian)(dian)(dian)(dian)(dian)系統(tong)。家(jia)(jia)用(yong)太陽(yang)能(neng)(neng)發電(dian)(dian)(dian)(dian)(dian)系統(tong)由太陽(yang)能(neng)(neng)電(dian)(dian)(dian)(dian)(dian)池組(zu)、太陽(yang)能(neng)(neng)控制器、蓄電(dian)(dian)(dian)(dian)(dian)池（組(zu)）組(zu)成(cheng)。光(guang)(guang)伏(fu)(fu)發電(dian)(dian)(dian)(dian)(dian)的(de)主要原理(li)是(shi)半導體的(de)光(guang)(guang)電(dian)(dian)(dian)(dian)(dian)效應。光(guang)(guang)子(zi)(zi)(zi)照射(she)到金屬上(shang)時，集中式(shi)光(guang)(guang)伏(fu)(fu)電(dian)(dian)(dian)(dian)(dian)站，它的(de)能(neng)(neng)量可(ke)以(yi)被金屬中某個電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)全部吸收，太陽(yang)能(neng)(neng)光(guang)(guang)伏(fu)(fu)電(dian)(dian)(dian)(dian)(dian)站，電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)吸收的(de)能(neng)(neng)量足夠大，能(neng)(neng)克(ke)服金屬內部引力做功，離(li)開金屬表(biao)面(mian)逃逸出來，成(cheng)為光(guang)(guang)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)。

光(guang)伏(fu)發電(dian)系(xi)統(tong)(tong)是根據光(guang)產生(sheng)伏(fu)打效(xiao)應(ying)原理(li)將太(tai)(tai)陽(yang)能(neng)(neng)(neng)(neng)轉換(huan)為電(dian)能(neng)(neng)(neng)(neng)，無(wu)輻射，逆變器、配電(dian)柜等電(dian)子(zi)器件都通過(guo) EMC（電(dian)磁兼容性）測試(shi)，所以對人體沒(mei)有危害。獨(du)立(li)光(guang)伏(fu)電(dian)站包(bao)括邊遠(yuan)地區(qu)的(de)村莊(zhuang)供電(dian)系(xi)統(tong)(tong)，太(tai)(tai)陽(yang)能(neng)(neng)(neng)(neng)戶用(yong)電(dian)源系(xi)統(tong)(tong)，通信(xin)信(xin)號電(dian)源、陰極(ji)保護、太(tai)(tai)陽(yang)能(neng)(neng)(neng)(neng)路燈等各種帶有蓄電(dian)池(chi)的(de)可以獨(du)立(li)運行的(de)光(guang)伏(fu)發電(dian)系(xi)統(tong)(tong)。太(tai)(tai)陽(yang)能(neng)(neng)(neng)(neng)發電(dian)系(xi)統(tong)(tong)是利(li)用(yong)太(tai)(tai)陽(yang)能(neng)(neng)(neng)(neng)電(dian)池(chi)直接將太(tai)(tai)陽(yang)能(neng)(neng)(neng)(neng)轉換(huan)成電(dian)能(neng)(neng)(neng)(neng)的(de)發電(dian)系(xi)統(tong)(tong)。家用(yong)太(tai)(tai)陽(yang)能(neng)(neng)(neng)(neng)發電(dian)系(xi)統(tong)(tong)由(you)太(tai)(tai)陽(yang)能(neng)(neng)(neng)(neng)電(dian)池(chi)組(zu)、太(tai)(tai)陽(yang)能(neng)(neng)(neng)(neng)控制器、蓄電(dian)池(chi)（組(zu)）組(zu)成。

中國是光(guang)(guang)(guang)伏發(fa)(fa)電(dian)(dian)(dian)(dian)安(an)(an)裝量增長快的(de)國家，2011年(nian)的(de)光(guang)(guang)(guang)伏發(fa)(fa)電(dian)(dian)(dian)(dian)安(an)(an)裝量比2010年(nian)增長了約5倍(bei)，安(an)(an)慶(qing)光(guang)(guang)(guang)伏電(dian)(dian)(dian)(dian)站(zhan)，2011年(nian)電(dian)(dian)(dian)(dian)池(chi)產量達到20GW，約占的(de)65%。獨(du)立光(guang)(guang)(guang)伏發(fa)(fa)電(dian)(dian)(dian)(dian)也叫離網光(guang)(guang)(guang)伏發(fa)(fa)電(dian)(dian)(dian)(dian)。主要由太陽能電(dian)(dian)(dian)(dian)池(chi)組件、控(kong)制器、蓄電(dian)(dian)(dian)(dian)池(chi)組成，若要為交(jiao)流負載供電(dian)(dian)(dian)(dian)，還需(xu)要配(pei)置交(jiao)流逆(ni)變器。隨著(zhu)國家新(xin)能源產業的(de)發(fa)(fa)展和太陽能光(guang)(guang)(guang)伏發(fa)(fa)電(dian)(dian)(dian)(dian)的(de)普(pu)及，太陽能光(guang)(guang)(guang)伏電(dian)(dian)(dian)(dian)站(zhan)的(de)高(gao)產率和高(gao)可靠性的(de)特(te)點使得屋頂光(guang)(guang)(guang)伏電(dian)(dian)(dian)(dian)站(zhan)逐(zhu)漸得到用戶的(de)認可。大多數(shu)農村居民和企業主都在(zai)自家屋頂安(an)(an)裝了光(guang)(guang)(guang)伏電(dian)(dian)(dian)(dian)站(zhan)。
