安徽光伏加盟-烈陽(yang)光伏l多年經驗-光伏加盟代理商

多(duo)晶(jing)(jing)硅(gui)(gui)太(tai)(tai)陽電(dian)(dian)池(chi)(chi)的制(zhi)作工藝與(yu)單晶(jing)(jing)硅(gui)(gui)太(tai)(tai)陽電(dian)(dian)池(chi)(chi)差不(bu)多(duo)，但(dan)是(shi)多(duo)晶(jing)(jing)硅(gui)(gui)太(tai)(tai)陽能(neng)(neng)電(dian)(dian)池(chi)(chi)的光(guang)電(dian)(dian)轉換效率(lv)則要降低不(bu)少，其(qi)光(guang)電(dian)(dian)轉換效率(lv)約12%左右。從制(zhi)作成本(ben)上來講，比單晶(jing)(jing)硅(gui)(gui)太(tai)(tai)陽能(neng)(neng)電(dian)(dian)池(chi)(chi)要便宜一些，材料制(zhi)造簡便，節約電(dian)(dian)耗，總的生產成本(ben)較低，因此得到大量發展(zhan)。此外，多(duo)晶(jing)(jing)硅(gui)(gui)太(tai)(tai)陽能(neng)(neng)電(dian)(dian)池(chi)(chi)的使用壽命(ming)也(ye)要比單晶(jing)(jing)硅(gui)(gui)太(tai)(tai)陽能(neng)(neng)電(dian)(dian)池(chi)(chi)短(duan)。從性能(neng)(neng)價(jia)格比來講，單晶(jing)(jing)硅(gui)(gui)太(tai)(tai)陽能(neng)(neng)電(dian)(dian)池(chi)(chi)還(huan)略(lve)好。

光伏(fu)組件的逆變器

光伏(fu)(fu)電(dian)(dian)池(chi)組(zu)(zu)(zu)件(jian)(jian)分組(zu)(zu)(zu)陣(zhen)列連接(jie)要求。光伏(fu)(fu)電(dian)(dian)池(chi)組(zu)(zu)(zu)件(jian)(jian)在排布陣(zhen)列安裝時應(ying)根據可(ke)能(neng)選(xuan)用逆(ni)變器的(de)(de)(de)(de)額定(ding)工(gong)作電(dian)(dian)壓(ya)(ya)(ya)(V)范圍和(he)功(gong)率容(rong)量(W)等參數進(jin)行(xing)分組(zu)(zu)(zu)設計。電(dian)(dian)池(chi)組(zu)(zu)(zu)件(jian)(jian)可(ke)以通過同(tong)類型(xing)組(zu)(zu)(zu)件(jian)(jian)的(de)(de)(de)(de)串聯疊加電(dian)(dian)壓(ya)(ya)(ya)和(he)功(gong)率形(xing)(xing)成"一串"連接(jie)組(zu)(zu)(zu)件(jian)(jian)及相(xiang)應(ying)的(de)(de)(de)(de)輸出電(dian)(dian)壓(ya)(ya)(ya)(V)和(he)功(gong)率(W)。為了保證(zheng)光伏(fu)(fu)組(zu)(zu)(zu)件(jian)(jian)正常工(gong)作，只允許相(xiang)同(tong)型(xing)號的(de)(de)(de)(de)光伏(fu)(fu)組(zu)(zu)(zu)件(jian)(jian)進(jin)行(xing)串聯。多(duo)個光伏(fu)(fu)組(zu)(zu)(zu)件(jian)(jian)串聯后可(ke)以再進(jin)行(xing)并(bing)聯，并(bing)聯的(de)(de)(de)(de)光伏(fu)(fu)組(zu)(zu)(zu)件(jian)(jian)端(duan)電(dian)(dian)壓(ya)(ya)(ya)相(xiang)差不應(ying)超過10%。一串或多(duo)串組(zu)(zu)(zu)件(jian)(jian)通過并(bing)聯即形(xing)(xing)成"分組(zu)(zu)(zu)陣(zhen)列"，該"分組(zu)(zu)(zu)陣(zhen)列"的(de)(de)(de)(de)總(zong)功(gong)率(W)為所有組(zu)(zu)(zu)件(jian)(jian)功(gong)率的(de)(de)(de)(de)總(zong)和(he)，本附件(jian)(jian)中(zhong)的(de)(de)(de)(de)圖1給出了三(san)種光伏(fu)(fu)電(dian)(dian)池(chi)的(de)(de)(de)(de)串并(bing)聯形(xing)(xing)式。同(tong)一分組(zu)(zu)(zu)陣(zhen)列中(zhong)的(de)(de)(de)(de)組(zu)(zu)(zu)件(jian)(jian)在安裝時，應(ying)盡可(ke)能(neng)保證(zheng)具有相(xiang)同(tong)的(de)(de)(de)(de)太陽輻射條件(jian)(jian)。
