光伏(fu)發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)是(shi)太陽(yang)能發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)技(ji)術(shu)的(de)一(yi)種， 是(shi)根據光生(sheng)伏(fu)特1效應原(yuan)理產生(sheng)的(de)電(dian)(dian)(dian)(dian)能，并(bing)網(wang)太陽(yang)能發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)，利用(yong)太陽(yang)電(dian)(dian)(dian)(dian)池將太陽(yang)光能直接轉化為電(dian)(dian)(dian)(dian)能。不論(lun)是(shi)獨(du)立使用(yong)還是(shi)并(bing)網(wang)發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)，理論(lun)上(shang)講(jiang)，光伏(fu)發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)技(ji)術(shu)可(ke)以用(yong)于(yu)任何需要(yao)(yao)電(dian)(dian)(dian)(dian)源(yuan)的(de)場(chang)合，太陽(yang)能發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)哪家好，上(shang)至航天器(qi)，下至家用(yong)電(dian)(dian)(dian)(dian)源(yuan)，大到兆瓦級電(dian)(dian)(dian)(dian)站，小到玩具，光伏(fu)電(dian)(dian)(dian)(dian)源(yuan)可(ke)以無(wu)處不在(zai)。目前，光伏(fu)發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)產品主(zhu)要(yao)(yao)用(yong)于(yu)三大方面：一(yi)是(shi)為無(wu)電(dian)(dian)(dian)(dian)場(chang)合提供電(dian)(dian)(dian)(dian)源(yuan)，主(zhu)要(yao)(yao)為廣大無(wu)電(dian)(dian)(dian)(dian)地區居民生(sheng)活生(sheng)產提供電(dian)(dian)(dian)(dian)力，還有微波中(zhong)繼電(dian)(dian)(dian)(dian)源(yuan)等(deng)，太陽(yang)能發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)公司，另外，還包括一(yi)些移動電(dian)(dian)(dian)(dian)源(yuan)和備用(yong)電(dian)(dian)(dian)(dian)源(yuan)；

光伏發電設備的好處

有效(xiao)防雷(lei)(lei)，更(geng)安全：太陽能(neng)發電(dian)(dian)設備(bei)系(xi)(xi)統(tong)(tong)電(dian)(dian)氣(qi)設備(bei)都具有防雷(lei)(lei)功能(neng)，而且，發電(dian)(dian)系(xi)(xi)統(tong)(tong)充(chong)分利用每(mei)片光(guang)伏(fu)電(dian)(dian)池組件(jian)下方的鋼結構支架(jia)作(zuo)為自然接地體(ti)，根據現場實際情況及(ji)土壤電(dian)(dian)阻率(lv)敷(fu)設不同(tong)的人工接地網(wang)，以滿足接地電(dian)(dian)阻的要求(qiu)，重點區域加強(qiang)均勻布置以滿足接觸電(dian)(dian)勢和跨步(bu)電(dian)(dian)壓的要求(qiu)。如果有惡劣(lie)雷(lei)(lei)電(dian)(dian)天氣(qi)，光(guang)伏(fu)能(neng)源(yuan)發電(dian)(dian)系(xi)(xi)統(tong)(tong)能(neng)夠有效(xiao)避免房屋內電(dian)(dian)氣(qi)設備(bei)遭到直擊雷(lei)(lei)、感應(ying)雷(lei)(lei)等(deng)的影響，人身及(ji)財物更(geng)加安全。

光伏發電(dian)新能(neng)源將給農村帶來那些(xie)便利

在(zai)光(guang)(guang)伏(fu)發(fa)(fa)電剛開(kai)始能夠應(ying)用(yong)的(de)(de)時候(hou)，所有的(de)(de)實際應(ying)用(yong)的(de)(de)項目都(dou)是(shi)在(zai)農(nong)(nong)村進行的(de)(de)，只不過(guo)當時所有的(de)(de)投資都(dou)是(shi)的(de)(de)資助項目，或者(zhe)屬于扶(fu)貧項目。 正如《中(zhong)國農(nong)(nong)村能源問(wen)題系列文章之三：農(nong)(nong)村新能源的(de)(de)挑戰與機遇》一(yi)文中(zhong)所提到的(de)(de)，現(xian)在(zai)光(guang)(guang)伏(fu)界的(de)(de)不少先驅(qu)都(dou)有過(guo)在(zai)青海、西藏等地為農(nong)(nong)牧民(min)安裝光(guang)(guang)伏(fu)發(fa)(fa)電板的(de)(de)經歷。這些(xie)樣板或項目的(de)(de)影(ying)響其實要(yao)比(bi)人們想象的(de)(de)大得(de)多(duo)。農(nong)(nong)村中(zhong)原始的(de)(de)能源，光(guang)(guang)伏(fu)發(fa)(fa)電屋頂安裝，如薪柴、秸稈等，以現(xian)在(zai)的(de)(de)標準來看，都(dou)屬于可再生能源，盡(jin)管(guan)它們不是(shi)清(qing)潔能源。
