獨立光伏(fu)發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)也叫離網光伏(fu)發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)。主要(yao)由太陽能電(dian)(dian)(dian)(dian)(dian)池(chi)組件、控制器、蓄電(dian)(dian)(dian)(dian)(dian)池(chi)組成，若要(yao)為交流(liu)負載供電(dian)(dian)(dian)(dian)(dian)，還需要(yao)配置交流(liu)逆變器。中國太陽能光伏(fu)發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)發(fa)(fa)站潛(qian)力巨大(da)(da)，配合積極(ji)穩定的(de)政策扶(fu)持，到2030年(nian)光伏(fu)裝機容(rong)量將(jiang)達1億千瓦，年(nian)發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)量可(ke)達1.3億兆瓦時，屋頂(ding)光伏(fu)發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)，相當于(yu)少建30多個大(da)(da)型煤電(dian)(dian)(dian)(dian)(dian)廠(chang)。帶有蓄電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)并網發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)系統具(ju)有可(ke)調度性，可(ke)以根據需要(yao)并入(ru)或退出電(dian)(dian)(dian)(dian)(dian)網，還具(ju)有備用電(dian)(dian)(dian)(dian)(dian)源的(de)功(gong)能，當電(dian)(dian)(dian)(dian)(dian)網因故停電(dian)(dian)(dian)(dian)(dian)時可(ke)緊急供電(dian)(dian)(dian)(dian)(dian)。

中(zhong)國太(tai)(tai)陽能(neng)(neng)(neng)(neng)光(guang)(guang)伏(fu)發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)發站潛力巨大(da)，配合積極穩(wen)定(ding)的(de)政策(ce)扶持(chi)，到(dao)2030年光(guang)(guang)伏(fu)裝機容量(liang)(liang)將(jiang)達(da)1億(yi)千瓦，年發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)可達(da)1.3億(yi)兆瓦時(shi)(shi)，相當于少建30多(duo)個大(da)型煤電(dian)(dian)(dian)(dian)(dian)(dian)(dian)廠(chang)。光(guang)(guang)伏(fu)發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)主要原理是半導(dao)體的(de)光(guang)(guang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)效應。光(guang)(guang)子(zi)(zi)照射到(dao)金(jin)(jin)屬上時(shi)(shi)，它的(de)能(neng)(neng)(neng)(neng)量(liang)(liang)可以被(bei)金(jin)(jin)屬中(zhong)某個電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)全部(bu)吸收，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)吸收的(de)能(neng)(neng)(neng)(neng)量(liang)(liang)足夠大(da)，光(guang)(guang)伏(fu)發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)項(xiang)目，能(neng)(neng)(neng)(neng)克(ke)服金(jin)(jin)屬內部(bu)引力做功，離開金(jin)(jin)屬表面逃逸出來，成為(wei)光(guang)(guang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)。獨立(li)光(guang)(guang)伏(fu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)站包(bao)括邊遠地區的(de)村莊(zhuang)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)系(xi)統(tong)，光(guang)(guang)伏(fu)發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)儲能(neng)(neng)(neng)(neng)系(xi)統(tong)，太(tai)(tai)陽能(neng)(neng)(neng)(neng)戶用電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源系(xi)統(tong)，光(guang)(guang)伏(fu)發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，通信信號電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源、陰極保護(hu)、太(tai)(tai)陽能(neng)(neng)(neng)(neng)路燈等(deng)各種(zhong)帶(dai)有蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)可以獨立(li)運行的(de)光(guang)(guang)伏(fu)發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)系(xi)統(tong)。
