一、屋頂光伏發電和地面光伏發電對比
地(di)(di)面電(dian)(dian)站(zhan)和屋頂分布式電(dian)(dian)站(zhan)是目前光(guang)伏電(dian)(dian)站(zhan)投資(zi)的(de)(de)兩(liang)大類型。地(di)(di)面電(dian)(dian)站(zhan)因擁有清晰的(de)(de)產權而容易獲得金融支持,安裝、接入(ru)方式簡單,只與電(dian)(dian)網有結算關系,這(zhe)些都(dou)是其優點。但同時還(huan)要看到,地(di)(di)面電(dian)(dian)站(zhan)存在占用大量土地(di)(di)、補貼到位時間長(chang)等不足。此外,地(di)(di)面電(dian)(dian)站(zhan)還(huan)會受(shou)到電(dian)(dian)改等因素的(de)(de)影響,由于發電(dian)(dian)側放開競價(jia)上網,光(guang)伏地(di)(di)面電(dian)(dian)站(zhan)競爭力就會顯得嚴重不足。
另(ling)外還需要考慮到(dao),屋(wu)(wu)頂(ding)(ding)分(fen)(fen)布(bu)式電(dian)站(zhan)往往會因產權(quan)不夠清晰(xi),而不容易獲得金融支持;同時(shi),屋(wu)(wu)頂(ding)(ding)分(fen)(fen)布(bu)式電(dian)站(zhan)的(de)安(an)裝、接入方(fang)(fang)式相(xiang)對復雜;其結算關系(xi)上存在屋(wu)(wu)頂(ding)(ding)業主、投資方(fang)(fang)和電(dian)網三(san)方(fang)(fang)關系(xi),業主有違約風險(xian)等。必須看到(dao),不占用土地、電(dian)量消(xiao)納不受限制、首(shou)次補(bu)貼到(dao)位時(shi)間為(wei)一個季度等,都是(shi)屋(wu)(wu)頂(ding)(ding)分(fen)(fen)布(bu)式電(dian)站(zhan)的(de)優(you)勢。同時(shi),由于是(shi)直供電(dian),屋(wu)(wu)頂(ding)(ding)分(fen)(fen)布(bu)式電(dian)站(zhan)未來會成為(wei)售電(dian)公司的(de)首(shou)選。
二、屋頂光伏發電有沒有輻射
屋頂光伏發電沒有(you)輻射(she),不(bu)(bu)會對人體(ti)有(you)害。光伏發電是將光能(neng)通過半導體(ti)的(de)(de)特性直(zhi)接(jie)轉(zhuan)化為直(zhi)流(liu)電能(neng)的(de)(de),再通過逆變(bian)(bian)器將直(zhi)流(liu)電轉(zhuan)換成可以(yi)被我(wo)們(men)使(shi)用(yong)的(de)(de)交流(liu)電。其中(zhong)沒有(you)任何化學變(bian)(bian)化以(yi)及核反應,所(suo)以(yi)光伏發電是不(bu)(bu)會有(you)輻射(she)的(de)(de)。光伏發電是無(wu)污染、無(wu)輻射(she),取之不(bu)(bu)盡用(yong)之不(bu)(bu)竭的(de)(de)清潔(jie)能(neng)源。
光(guang)(guang)伏(fu)(fu)組(zu)件(jian)(jian)(jian)本身在發(fa)電(dian)(dian)(dian)時并(bing)不(bu)產生任何電(dian)(dian)(dian)磁(ci)輻射,但(dan)是(shi)(shi)為了(le)將光(guang)(guang)伏(fu)(fu)組(zu)件(jian)(jian)(jian)所(suo)發(fa)的(de)(de)直流電(dian)(dian)(dian)轉變(bian)為交流電(dian)(dian)(dian)并(bing)實現和電(dian)(dian)(dian)網的(de)(de)連接(jie),通常需要很多的(de)(de)電(dian)(dian)(dian)力(li)設備(bei)和電(dian)(dian)(dian)子器(qi)件(jian)(jian)(jian),這(zhe)些設備(bei)在運行時會影響周(zhou)圍的(de)(de)電(dian)(dian)(dian)磁(ci)環境。 這(zhe)里(li)用光(guang)(guang)伏(fu)(fu)發(fa)電(dian)(dian)(dian)系(xi)(xi)統和電(dian)(dian)(dian)磁(ci)環境指代存在于光(guang)(guang)伏(fu)(fu)系(xi)(xi)統周(zhou)邊的(de)(de)由于光(guang)(guang)伏(fu)(fu)系(xi)(xi)統運行產生的(de)(de)電(dian)(dian)(dian)磁(ci)現象的(de)(de)總和。 經科學測定,太陽能光(guang)(guang)伏(fu)(fu)發(fa)電(dian)(dian)(dian)系(xi)(xi)統的(de)(de)電(dian)(dian)(dian)磁(ci)環境低于各項指標的(de)(de)限值(zhi)。在工(gong)頻段,太陽能光(guang)(guang)伏(fu)(fu)電(dian)(dian)(dian)站電(dian)(dian)(dian)磁(ci)環境甚至低于正常使用的(de)(de)常用家用電(dian)(dian)(dian)器(qi)時產生的(de)(de)量(liang)值(zhi);因為光(guang)(guang)伏(fu)(fu)組(zu)件(jian)(jian)(jian)是(shi)(shi)沒(mei)有(you)(you)輻射的(de)(de),相反它可(ke)以反射一些太陽光(guang)(guang)里(li)面的(de)(de)有(you)(you)害(hai)的(de)(de)紫外線,所(suo)以光(guang)(guang)伏(fu)(fu)組(zu)件(jian)(jian)(jian)不(bu)僅不(bu)會有(you)(you)危(wei)害(hai)還而會反射一部(bu)分有(you)(you)害(hai)的(de)(de)紫外線,對人體是(shi)(shi)沒(mei)有(you)(you)危(wei)害(hai)的(de)(de)。
