如何徹底解決光伏電池組件MC4插頭頻繁燒損 </p> <p> 1選題理由 </p> <p> 某光伏電站裝機(jī)容量達(dá)到500MW，在光伏電站中，電池組件作為發(fā)電主體設(shè)備，具有相當(dāng)重要作用，而MC4插頭燒損直接影響電站的發(fā)電量。平均每年MC4插頭燒損約為4000條。造成故障棄光電量約10.25萬(wàn)KW/h。為了提高設(shè)備供電可靠性，避免不必要的維修損失費(fèi)用，避免設(shè)備非計(jì)劃停運(yùn)引起的電量損失發(fā)生，減輕運(yùn)維人員的維護(hù)工作壓力，杜絕火災(zāi)***。 </p> <p> 2現(xiàn)狀調(diào)查 </p> <p> 某光伏電站共計(jì)安裝太陽(yáng)能組件2110842塊。每年春秋兩季是強(qiáng)風(fēng)沙天氣，比較高風(fēng)速可達(dá)26.2m/s。電站平均每年MC4插頭燒損約為4000條，因MC4插頭燒損損失電量10.25萬(wàn)kW/時(shí)，MC4插頭采購(gòu)費(fèi)1.2萬(wàn)元。 </p> <p> 1、電站組件數(shù)量龐大，電池組件MC4插頭的好壞直接影響到電站發(fā)電量，增加運(yùn)維人員的工作量。 </p> <p> 2、羊群要穿越電池組件支架下方容易扯開(kāi)處于下拉狀態(tài)組件之間連線的MC4插頭，對(duì)公司發(fā)展的第三產(chǎn)業(yè)養(yǎng)殖業(yè)造成損傷。 </p> <p>

全球光伏成本大幅降低，光伏度電競(jìng)爭(zhēng)力突顯。在經(jīng)歷了光伏組件成本和 BOS 大幅下降之后，光伏度電成本在全球部分地區(qū)已經(jīng)具備平價(jià)條件。組件降價(jià)會(huì)提升存量已鎖定電價(jià)項(xiàng)目經(jīng)濟(jì)性，推動(dòng)業(yè)主裝機(jī)意愿。根據(jù) Lazard 的度電成本分析，2019 年全球光伏度電成本已經(jīng)降至 40 美元/MWH。 </p> <p> <br /> </p> 國(guó)內(nèi)補(bǔ)貼逐步退坡，行業(yè)成長(zhǎng)逐步告別政策依賴。根據(jù)國(guó)家能源局發(fā)布的《國(guó)家能源局關(guān)于 2020 年風(fēng)電、光伏發(fā)電項(xiàng)目建設(shè)有關(guān)事項(xiàng)的通知（征求意見(jiàn)稿）》，2020 年度新建光伏發(fā)電項(xiàng)目補(bǔ)貼預(yù)算總額度為 15 億元，同比 2019 年下降 50%，其中補(bǔ)貼競(jìng)價(jià)項(xiàng)目（包括集中式光伏電站和工商業(yè)分布式光伏項(xiàng)目）補(bǔ)貼總額為 10 億元。預(yù)計(jì) 2021 年，國(guó)內(nèi)光伏行業(yè)將徹底告別補(bǔ)貼，完成化石能源**周期***步，走入平價(jià)時(shí)代。<p> 2.2 產(chǎn)線可在 perc

沉積（隧道結(jié)制備環(huán)節(jié)）、離子注入（或者擴(kuò)散裝備）和去繞鍍清洗環(huán)節(jié)設(shè)備，便可以實(shí)現(xiàn)設(shè)備的升級(jí)。目前**廠商 perc 產(chǎn)線均留有一定設(shè)備空間，有助于產(chǎn)線改造升級(jí)。 </p> <p> 設(shè)備國(guó)產(chǎn)化加速，產(chǎn)能投資額迅速下降。隨著近年來(lái) TopCon 設(shè)備國(guó)產(chǎn)化的加速，國(guó)內(nèi)廠商陸續(xù)完成 LPCVD 等**設(shè)備的國(guó)產(chǎn)化。TopCon 產(chǎn)能 1GW 投資成本從原有的 5~6億元降至目前 2~2.5 億元/GW 左右，和當(dāng)前 perc 產(chǎn)線設(shè)備投資成本（1.8~2 億元/GW ）相比，成本差異大幅降低。設(shè)備投資額的大幅下降有望推動(dòng) TopCon 技術(shù)加速發(fā)展。 </p> <p> <br /> 為什么光伏組件的系統(tǒng)電壓小于1KV？</p><div style="width:100%;text-align:
