一、太陽能發電系統是如何工作的？

　　陽光照射在太陽能電池板上(shang)，電(dian)(dian)池(chi)板被轉換成(cheng)電(dian)(dian)能(直流電(dian)(dian))。

　　太陽(yang)能逆變器將(jiang)直流電轉換成交流電。

　　逆變器轉換后的交流電可直接在家中使(shi)用。

二、唐山光伏發電設備的主要組成部分

　　1. 太陽能電池板(又稱光伏組件)

　　太(tai)(tai)(tai)陽(yang)(yang)(yang)能(neng)電(dian)池板(ban)是通過吸收(shou)太(tai)(tai)(tai)陽(yang)(yang)(yang)光(guang)的(de)(de)(de)光(guang)電(dian)效(xiao)應或光(guang)化學效(xiao)應，直接(jie)或間接(jie)將太(tai)(tai)(tai)陽(yang)(yang)(yang)輻射能(neng)量轉化為(wei)電(dian)能(neng)的(de)(de)(de)裝(zhuang)置。澳大利(li)亞市(shi)場上有兩種(zhong)太(tai)(tai)(tai)陽(yang)(yang)(yang)能(neng)電(dian)池板(ban):單晶硅(gui)和多晶硅(gui)太(tai)(tai)(tai)陽(yang)(yang)(yang)能(neng)電(dian)池板(ban)。它(ta)們之間有三個區(qu)別(bie)(bie):外觀、轉換(huan)率和制造工藝。然而(er)，對于用戶來(lai)說，兩種(zhong)太(tai)(tai)(tai)陽(yang)(yang)(yang)能(neng)電(dian)池板(ban)的(de)(de)(de)材料差別(bie)(bie)不大，它(ta)們的(de)(de)(de)使用壽命長，穩定性好(hao)。因此(ci)，太(tai)(tai)(tai)陽(yang)(yang)(yang)能(neng)電(dian)池板(ban)的(de)(de)(de)選擇(ze)標(biao)準可(ke)以(yi)簡化為(wei)兩點:1 .太(tai)(tai)(tai)陽(yang)(yang)(yang)能(neng)電(dian)池板(ban)可(ke)以(yi)在屋頂上工作(zuo)25-30年以(yi)上;2.擁(yong)有良(liang)好(hao)聲譽(yu)和質量保證(zheng)的(de)(de)(de)大品牌。

　　2. 太陽能逆(ni)變器(又(you)稱光伏逆(ni)變器)

　　太(tai)陽能逆變器(qi)(Solar inverter)。因為太(tai)陽能板所轉化的(de)電全部都要(yao)通(tong)(tong)過逆變器(qi)的(de)處理(li)才(cai)能對(dui)外輸出，因此逆變器(qi)是太(tai)陽能系統中重要(yao)的(de)組(zu)成部分(fen)。通(tong)(tong)常，太(tai)陽能逆變器(qi)可(ke)以有5-10年的(de)產品保質期(qi)。

　　3. 太(tai)陽能支架(jia)系統

　　太陽能(neng)支架系(xi)統是用來將(jiang)太陽能(neng)板(ban)固(gu)定(ding)在各種屋頂上的裝置，它們(men)的質量(liang)也有著(zhu)舉足輕重(zhong)的作用。

　　4. 電氣(qi)配件及標(biao)簽

　　太陽(yang)(yang)能(neng)發電系(xi)(xi)統中(zhong)還(huan)有許多必不可少的電氣配件(jian)，每一部分的零件(jian)都會使用(yong)(yong)貼紙(zhi)標簽進行標注，它們在(zai)太陽(yang)(yang)能(neng)發電系(xi)(xi)統中(zhong)的作用(yong)(yong)同樣不可忽視(shi)。

三、太陽系與互聯網相連

　　太(tai)陽能(neng)發(fa)電(dian)(dian)(dian)(dian)系統(tong)(tong)(tong)(tong)可分為并網(wang)系統(tong)(tong)(tong)(tong)和離網(wang)系統(tong)(tong)(tong)(tong)，目前主(zhu)要采用(yong)并網(wang)系統(tong)(tong)(tong)(tong)，主(zhu)要依(yi)靠(kao)現有的電(dian)(dian)(dian)(dian)網(wang)連接太(tai)陽能(neng)發(fa)電(dian)(dian)(dian)(dian)、家(jia)(jia)電(dian)(dian)(dian)(dian)和公共電(dian)(dian)(dian)(dian)網(wang)。因此(ci)，太(tai)陽能(neng)電(dian)(dian)(dian)(dian)網(wang)連接系統(tong)(tong)(tong)(tong)是(shi)指(zhi)通過(guo)(guo)智能(neng)電(dian)(dian)(dian)(dian)表(biao)連接整個太(tai)陽能(neng)系統(tong)(tong)(tong)(tong)到外部電(dian)(dian)(dian)(dian)網(wang)，如果(guo)太(tai)陽能(neng)發(fa)電(dian)(dian)(dian)(dian)能(neng)力(li)超過(guo)(guo)家(jia)(jia)庭用(yong)電(dian)(dian)(dian)(dian)量(liang)，則將(jiang)過(guo)(guo)剩(sheng)的電(dian)(dian)(dian)(dian)力(li)轉移到公共電(dian)(dian)(dian)(dian)網(wang)。當太(tai)陽能(neng)發(fa)電(dian)(dian)(dian)(dian)不(bu)(bu)(bu)能(neng)滿足國內(nei)用(yong)電(dian)(dian)(dian)(dian)需(xu)求(qiu)時，實時外出供電(dian)(dian)(dian)(dian)。上述過(guo)(guo)程是(shi)由智能(neng)電(dian)(dian)(dian)(dian)表(biao)自動完成(cheng)的，不(bu)(bu)(bu)需(xu)要人工操作(zuo)。不(bu)(bu)(bu)同地區和電(dian)(dian)(dian)(dian)力(li)供應商對太(tai)陽能(neng)電(dian)(dian)(dian)(dian)網(wang)運行(xing)有不(bu)(bu)(bu)同的要求(qiu)。

四、太(tai)陽能(neng)系統的好處

　　安裝太(tai)陽(yang)(yang)能的(de)兩個實際的(de)好處是節省電(dian)(dian)(dian)費(fei)(fei)和將多(duo)(duo)余的(de)電(dian)(dian)(dian)力(li)賣給電(dian)(dian)(dian)網(wang)以(yi)獲利。太(tai)陽(yang)(yang)能并(bing)網(wang)供電(dian)(dian)(dian)系(xi)(xi)統(無電(dian)(dian)(dian)池供電(dian)(dian)(dian)系(xi)(xi)統)在供電(dian)(dian)(dian)時首先向(xiang)家(jia)庭(ting)或(huo)企(qi)業(ye)供電(dian)(dian)(dian)。換句話說(shuo)，如(ru)果(guo)這(zhe)個家(jia)庭(ting)目前是由(you)太(tai)陽(yang)(yang)能系(xi)(xi)統供電(dian)(dian)(dian)的(de)，那么這(zhe)部分(fen)電(dian)(dian)(dian)力(li)將是免費(fei)(fei)的(de)。家(jia)庭(ting)的(de)用電(dian)(dian)(dian)量低于太(tai)陽(yang)(yang)能。因此，多(duo)(duo)余的(de)電(dian)(dian)(dian)力(li)可(ke)以(yi)賣給電(dian)(dian)(dian)網(wang)，以(yi)抵消下一個電(dian)(dian)(dian)費(fei)(fei)賬(zhang)單的(de)成本。

太(tai)陽能發(fa)電系(xi)統(tong)就是這樣發(fa)電的，大(da)家(jia)知(zhi)道了嗎？
