光伏發電的優勢

有效(xiao)緩解(jie)人地(di)矛盾，促(cu)進社(she)會經濟可持續發展(zhan)。光伏農(nong)業大棚(peng)發電以及漁(yu)光互補項目利用的(de)(de)是農(nong)業大棚(peng)的(de)(de)棚(peng)頂及水面，并不占用地(di)面，也不會改變(bian)土(tu)地(di)使用性(xing)質，因(yin)此能(neng)夠節(jie)約土(tu)地(di)資源(yuan)。可在有效(xiao)扭轉人口(kou)大量(liang)增加情況(kuang)下耕地(di)大量(liang)減(jian)少方(fang)面起(qi)到積極(ji)作用，可以直接提高(gao)當地(di)農(nong)民的(de)(de)經濟收入(ru)。

可(ke)靈(ling)活創造適宜不同農(nong)(nong)作(zuo)物(wu)生長的(de)環境。通過在農(nong)(nong)業大棚(peng)上架設不同透(tou)光(guang)率的(de)太陽能電池板，能滿足(zu)不同作(zuo)物(wu)的(de)采(cai)光(guang)需求，可(ke)種植(zhi)有機農(nong)(nong)產品、名貴苗木(mu)等各類高附加值(zhi)作(zuo)物(wu)，還能實現反(fan)季種植(zhi)、精品種植(zhi)。

光伏發電的原理

光伏(fu)發電(dian)(dian)(dian)方(fang)式是利用光電(dian)(dian)(dian)效(xiao)應，將(jiang)太(tai)陽(yang)(yang)(yang)輻射能(neng)(neng)直(zhi)接轉換成(cheng)(cheng)電(dian)(dian)(dian)能(neng)(neng)，光—電(dian)(dian)(dian)轉換的(de)(de)(de)基本(ben)裝(zhuang)置(zhi)就(jiu)是太(tai)陽(yang)(yang)(yang)能(neng)(neng)電(dian)(dian)(dian)池。太(tai)陽(yang)(yang)(yang)能(neng)(neng)電(dian)(dian)(dian)池是一種(zhong)由于光生(sheng)伏(fu)特(te)1效(xiao)應而將(jiang)太(tai)陽(yang)(yang)(yang)光能(neng)(neng)直(zhi)接轉化為(wei)電(dian)(dian)(dian)能(neng)(neng)的(de)(de)(de)器(qi)件，是一個(ge)半導(dao)體光電(dian)(dian)(dian)二(er)極管，當(dang)太(tai)陽(yang)(yang)(yang)光照到光電(dian)(dian)(dian)二(er)極管上時(shi)，光電(dian)(dian)(dian)二(er)極管就(jiu)會把太(tai)陽(yang)(yang)(yang)的(de)(de)(de)光能(neng)(neng)變成(cheng)(cheng)電(dian)(dian)(dian)能(neng)(neng)，產(chan)生(sheng)電(dian)(dian)(dian)流。當(dang)許多個(ge)電(dian)(dian)(dian)池串聯(lian)或(huo)并聯(lian)起來就(jiu)可以成(cheng)(cheng)為(wei)有(you)比較大的(de)(de)(de)輸(shu)出功率的(de)(de)(de)太(tai)陽(yang)(yang)(yang)能(neng)(neng)電(dian)(dian)(dian)池方(fang)陣了。太(tai)陽(yang)(yang)(yang)能(neng)(neng)電(dian)(dian)(dian)池是一種(zhong)大有(you)前途(tu)的(de)(de)(de)新(xin)型電(dian)(dian)(dian)源，具有(you)永1久性、清潔(jie)性和靈(ling)活性三大優點(dian)。

太(tai)陽(yang)(yang)能(neng)電(dian)(dian)池(chi)(chi)組(zu)件結構簡(jian)單，體積小(xiao)、重量輕，便于(yu)運(yun)輸(shu)和安裝(zhuang)。光(guang)伏(fu)發(fa)電(dian)(dian)系(xi)統(tong)建設周(zhou)期短，而且根據用電(dian)(dian)負(fu)荷容量可(ke)大(da)(da)可(ke)小(xiao)，方便靈活，極易(yi)組(zu)合、擴容。太(tai)陽(yang)(yang)能(neng)電(dian)(dian)池(chi)(chi)是一(yi)種大(da)(da)有前途的(de)新(xin)型電(dian)(dian)源(yuan)，具有永1久性(xing)、清潔性(xing)和靈活性(xing)三大(da)(da)優點。太(tai)陽(yang)(yang)能(neng)光(guang)伏(fu)發(fa)電(dian)(dian)與火(huo)力發(fa)電(dian)(dian)、核能(neng)發(fa)電(dian)(dian)相(xiang)比，并(bing)網光(guang)伏(fu)發(fa)電(dian)(dian)，太(tai)陽(yang)(yang)能(neng)電(dian)(dian)池(chi)(chi)不會引起環境污染；太(tai)陽(yang)(yang)能(neng)電(dian)(dian)池(chi)(chi)可(ke)以大(da)(da)中小(xiao)并(bing)舉，大(da)(da)到百萬千瓦的(de)中型電(dian)(dian)站(zhan)，小(xiao)到只供一(yi)戶(hu)用電(dian)(dian)的(de)獨立太(tai)陽(yang)(yang)能(neng)發(fa)電(dian)(dian)系(xi)統(tong)，這(zhe)些特(te)點是其他電(dian)(dian)源(yuan)無法比擬(ni)的(de)。
