光伏發電的適用范圍

光(guang)(guang)(guang)伏(fu)(fu)發電(dian)(dian)(dian)已經在(zai)許多應用領(ling)域被證明在(zai)技(ji)術(shu)上(shang)是(shi)成熟的，在(zai)經濟上(shang)是(shi)合算的。從遠(yuan)期看，光(guang)(guang)(guang)伏(fu)(fu)發電(dian)(dian)(dian)將以(yi)分散式電(dian)(dian)(dian)源進入電(dian)(dian)(dian)力市(shi)場，并部分取代常(chang)(chang)規能源；從近期看，光(guang)(guang)(guang)伏(fu)(fu)發電(dian)(dian)(dian)可以(yi)作為常(chang)(chang)規能源的補充(chong)，來(lai)了解一下光(guang)(guang)(guang)伏(fu)(fu)發電(dian)(dian)(dian)的應用領(ling)域吧！通(tong)訊(xun)/通(tong)信領(ling)域：太陽能無人值守微波中繼站(zhan)(zhan)、光(guang)(guang)(guang)纜維(wei)護站(zhan)(zhan)、廣播/通(tong)訊(xun)/尋呼電(dian)(dian)(dian)源系統(tong)(tong)；農村載波電(dian)(dian)(dian)話光(guang)(guang)(guang)伏(fu)(fu)系統(tong)(tong)、小型通(tong)信機、士兵GPS供電(dian)(dian)(dian)等。

無論(lun)從世(shi)界還是(shi)(shi)從中(zhong)國來(lai)看，常規能源(yuan)都是(shi)(shi)很(hen)有限的(de)(de)。中(zhong)國的(de)(de)一次能源(yuan)儲(chu)量遠遠低于世(shi)界的(de)(de)平(ping)均水平(ping)，大約(yue)只有世(shi)界總儲(chu)量的(de)(de)10%。太陽能是(shi)(shi)人類取之不盡用之不竭(jie)的(de)(de)可再生能源(yuan)，具(ju)有充分的(de)(de)清潔性(xing)、安全性(xing)、相對(dui)的(de)(de)廣(guang)泛性(xing)、確實的(de)(de)長壽命和免維護性(xing)、資源(yuan)的(de)(de)充足性(xing)及(ji)潛在的(de)(de)經濟性(xing)等(deng)優點，在長期的(de)(de)能源(yuan)戰略中(zhong)具(ju)有重(zhong)要地位。

與常用的火力發電(dian)系統相(xiang)比，光伏發電(dian)的優點主(zhu)要體現于:

①無枯竭危險;

②，無(wu)(wu)噪(zao)聲，光伏發電工程，無(wu)(wu)污(wu)染排放外(wai)，比較干凈(jing)(無(wu)(wu)公害);

③不受資(zi)源分布(bu)地域的(de)限制，可利(li)用建筑屋面的(de)優勢;例如(ru)，無電(dian)地區(qu)，以及地形復(fu)雜地區(qu);

④無需消耗(hao)燃料和架設輸電(dian)線路即可(ke)就地發電(dian)供電(dian);

⑤能源質量高;

⑥使用(yong)者從(cong)感情上(shang)容(rong)易接(jie)受;

⑦建設周期(qi)短(duan)，獲取能源(yuan)花費的時間短(duan)。

其作用是貯存太陽(yang)能電池方陣受光照時(shi)發出的(de)電能并可(ke)隨時(shi)向負載(zai)供(gong)電。

太(tai)陽能電(dian)池(chi)發電(dian)對所用蓄電(dian)池(chi)組的基(ji)本要(yao)求是:a.自放電(dian)率低(di);b.使(shi)用壽命長;c.深放電(dian)能力(li)強;d.充(chong)電(dian);e.少維(wei)(wei)護(hu)或免維(wei)(wei)護(hu);f.工(gong)作溫(wen)度(du)范圍(wei)寬(kuan);g.價格低(di)廉。
