一、屋頂光伏發電和地面光伏發電對比

地(di)面電(dian)站(zhan)(zhan)和屋(wu)頂分布式(shi)電(dian)站(zhan)(zhan)是(shi)目前光伏(fu)電(dian)站(zhan)(zhan)投資的(de)兩大類型。地(di)面電(dian)站(zhan)(zhan)因(yin)(yin)擁有清晰(xi)的(de)產(chan)權而容易獲得金融(rong)支(zhi)持，安裝、接入(ru)方式(shi)簡單(dan)，只與電(dian)網有結(jie)算關系，這(zhe)些(xie)都是(shi)其優點(dian)。但(dan)同時還要(yao)看到(dao)，地(di)面電(dian)站(zhan)(zhan)存在占用大量土地(di)、補(bu)貼到(dao)位時間長等不足(zu)。此(ci)外，地(di)面電(dian)站(zhan)(zhan)還會受到(dao)電(dian)改(gai)等因(yin)(yin)素(su)的(de)影響，由于發電(dian)側(ce)放(fang)開競價(jia)上網，光伏(fu)地(di)面電(dian)站(zhan)(zhan)競爭力就會顯得嚴重不足(zu)。

另外還需要考(kao)慮到，屋頂(ding)(ding)分(fen)(fen)布式電站往(wang)往(wang)會因產權不(bu)夠清晰，而不(bu)容易獲(huo)得金融支持；同(tong)時(shi)，屋頂(ding)(ding)分(fen)(fen)布式電站的安(an)裝(zhuang)、接入方式相(xiang)對復雜；其結(jie)算關(guan)(guan)系(xi)(xi)上存在屋頂(ding)(ding)業(ye)主、投(tou)資方和電網三方關(guan)(guan)系(xi)(xi)，業(ye)主有違約風險等。必須看到，不(bu)占用(yong)土(tu)地、電量(liang)消納不(bu)受限(xian)制(zhi)、首次補貼到位時(shi)間為一個(ge)季度等，都(dou)是(shi)屋頂(ding)(ding)分(fen)(fen)布式電站的優勢。同(tong)時(shi)，由于是(shi)直供(gong)電，屋頂(ding)(ding)分(fen)(fen)布式電站未來會成(cheng)為售電公司的首選。

二、屋頂光伏發電有沒有輻射

屋頂光伏發電沒(mei)有輻(fu)射(she)(she)，不會對人體有害(hai)。光(guang)(guang)伏發(fa)電是將(jiang)光(guang)(guang)能(neng)通過半導體的(de)(de)特性直(zhi)接轉(zhuan)化為直(zhi)流電能(neng)的(de)(de)，再(zai)通過逆變器將(jiang)直(zhi)流電轉(zhuan)換成可以(yi)(yi)被我(wo)們使(shi)用的(de)(de)交(jiao)流電。其中沒(mei)有任何化學變化以(yi)(yi)及核反(fan)應，所以(yi)(yi)光(guang)(guang)伏發(fa)電是不會有輻(fu)射(she)(she)的(de)(de)。光(guang)(guang)伏發(fa)電是無污(wu)染、無輻(fu)射(she)(she)，取(qu)之(zhi)不盡(jin)用之(zhi)不竭的(de)(de)清(qing)潔(jie)能(neng)源(yuan)。

光(guang)(guang)伏(fu)(fu)組(zu)(zu)件(jian)(jian)(jian)本身在發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)時(shi)(shi)并(bing)不(bu)產(chan)生(sheng)任何電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)輻(fu)(fu)射，但是為(wei)了將光(guang)(guang)伏(fu)(fu)組(zu)(zu)件(jian)(jian)(jian)所(suo)(suo)發(fa)(fa)的(de)(de)直流(liu)電(dian)(dian)(dian)(dian)(dian)轉(zhuan)變為(wei)交流(liu)電(dian)(dian)(dian)(dian)(dian)并(bing)實現和電(dian)(dian)(dian)(dian)(dian)網的(de)(de)連(lian)接，通(tong)常需(xu)要很多的(de)(de)電(dian)(dian)(dian)(dian)(dian)力設(she)備和電(dian)(dian)(dian)(dian)(dian)子(zi)器(qi)件(jian)(jian)(jian)，這(zhe)些(xie)設(she)備在運行時(shi)(shi)會(hui)影響周圍的(de)(de)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)環(huan)境。 這(zhe)里用光(guang)(guang)伏(fu)(fu)發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)系(xi)(xi)統(tong)和電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)環(huan)境指代存在于(yu)光(guang)(guang)伏(fu)(fu)系(xi)(xi)統(tong)周邊的(de)(de)由于(yu)光(guang)(guang)伏(fu)(fu)系(xi)(xi)統(tong)運行產(chan)生(sheng)的(de)(de)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)現象的(de)(de)總和。 經科學(xue)測(ce)定(ding)，太(tai)陽能(neng)光(guang)(guang)伏(fu)(fu)發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)系(xi)(xi)統(tong)的(de)(de)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)環(huan)境低于(yu)各項指標的(de)(de)限值(zhi)。在工頻(pin)段，太(tai)陽能(neng)光(guang)(guang)伏(fu)(fu)電(dian)(dian)(dian)(dian)(dian)站電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)環(huan)境甚至低于(yu)正(zheng)常使用的(de)(de)常用家用電(dian)(dian)(dian)(dian)(dian)器(qi)時(shi)(shi)產(chan)生(sheng)的(de)(de)量值(zhi)；因(yin)為(wei)光(guang)(guang)伏(fu)(fu)組(zu)(zu)件(jian)(jian)(jian)是沒有(you)輻(fu)(fu)射的(de)(de)，相反它可以反射一些(xie)太(tai)陽光(guang)(guang)里面的(de)(de)有(you)害(hai)(hai)的(de)(de)紫(zi)外線(xian)，所(suo)(suo)以光(guang)(guang)伏(fu)(fu)組(zu)(zu)件(jian)(jian)(jian)不(bu)僅不(bu)會(hui)有(you)危害(hai)(hai)還而會(hui)反射一部分有(you)害(hai)(hai)的(de)(de)紫(zi)外線(xian)，對人體是沒有(you)危害(hai)(hai)的(de)(de)。
