太(tai)陽能(neng)(neng)光(guang)伏板的(de)功能(neng)(neng)是收集(ji)電(dian)能(neng)(neng)，幾(ji)塊(kuai)連在一起的(de)光(guang)伏板就能(neng)(neng)組成(cheng)一個(ge)線(xian)路，太(tai)陽能(neng)(neng)光(guang)伏板發出(chu)的(de)電(dian)一般(ban)都(dou)是直流(liu)(liu)電(dian)。匯流(liu)(liu)箱，匯流(liu)(liu)箱的(de)功能(neng)(neng)是把(ba)在它(ta)附近的(de)幾(ji)路電(dian)流(liu)(liu)線(xian)路聚集(ji)到一起，隨后統一成(cheng)一路向上級傳(chuan)送。逆(ni)(ni)(ni)變(bian)(bian)(bian)器，在匯流(liu)(liu)箱匯總之(zhi)后的(de)電(dian)流(liu)(liu)直接就會輸送到逆(ni)(ni)(ni)變(bian)(bian)(bian)器的(de)，因(yin)為在這個(ge)時候電(dian)流(liu)(liu)會很大(da)，所(suo)以(yi)我們選擇逆(ni)(ni)(ni)變(bian)(bian)(bian)器的(de)時候必須要(yao)把(ba)功率算好。當直流(liu)(liu)電(dian)通過(guo)逆(ni)(ni)(ni)變(bian)(bian)(bian)器的(de)逆(ni)(ni)(ni)變(bian)(bian)(bian)作用，就能(neng)(neng)夠讓直流(liu)(liu)變(bian)(bian)(bian)成(cheng)了(le)低(di)壓的(de)交流(liu)(liu)了(le)。

影(ying)響光伏組(zu)(zu)件(jian)發電(dian)量的因素陰影(ying)遮擋：組(zu)(zu)件(jian)在(zai)工作過程中由于(yu)陰影(ying)的部(bu)分遮擋以及灰塵的沉降程度(du)(du)不鳥糞(fen)的污染會造成(cheng)(cheng)“熱斑效應”，被遮擋部(bu)分組(zu)(zu)件(jian)將不提供功率(lv)貢獻并在(zai)組(zu)(zu)件(jian)內(nei)部(bu)成(cheng)(cheng)為耗能負載(zai)，光伏發電(dian)公司廠家(jia)，同時造成(cheng)(cheng)組(zu)(zu)件(jian)局(ju)部(bu)溫度(du)(du)升高，過熱區域(yu)可引起EVA加快(kuai)老化變黃，使該區域(yu)透光率(lv)下降，從而使熱斑進一步惡化，導(dao)致(zhi)太(tai)陽能電(dian)池組(zu)(zu)件(jian)的失(shi)效加劇。
