太陽能發電的優點

1、太陽能隨(sui)處可處，可就近供電，不必長(chang)距離輸(shu)送，避免(mian)了長(chang)距離輸(shu)電線路的(de)損失；

2、太陽能發(fa)電不會產生(sheng)任何廢棄物，沒有污染、噪(zao)聲(sheng)等公害，對環境無不良影響，是理想的清潔能源(yuan)；

3、太(tai)陽(yang)能(neng)發電(dian)系統建設(she)周期(qi)短(duan)，方便靈(ling)活(huo)，而且(qie)可以根(gen)據(ju)負荷的增減，太(tai)陽(yang)能(neng)發電(dian)，任意添加或減少(shao)太(tai)陽(yang)能(neng)方陣容量，避免浪費(fei)。

太陽能(neng)發電系(xi)(xi)統(tong)(tong)分為(wei)離(li)網發電系(xi)(xi)統(tong)(tong)與并網發電系(xi)(xi)統(tong)(tong)：

1、離網發(fa)電(dian)系統。主(zhu)要由太陽能電(dian)池(chi)組件、控制(zhi)器、蓄(xu)電(dian)池(chi)組成，若(ruo)要為(wei)交流負載供(gong)電(dian)，還(huan)需要配置交流逆(ni)變(bian)器。

2、并網(wang)(wang)發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)系(xi)統就是(shi)太(tai)陽(yang)能組件(jian)產(chan)生的(de)(de)直(zhi)流電(dian)(dian)(dian)(dian)經過并網(wang)(wang)逆(ni)變器轉換成符合市電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)網(wang)(wang)要(yao)求的(de)(de)交流電(dian)(dian)(dian)(dian)這后(hou)直(zhi)接接入(ru)公共電(dian)(dian)(dian)(dian)網(wang)(wang)。并網(wang)(wang)發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)系(xi)統有集中式(shi)大(da)型并網(wang)(wang)電(dian)(dian)(dian)(dian)站(zhan)一(yi)(yi)(yi)般都是(shi)國(guo)1家級電(dian)(dian)(dian)(dian)站(zhan)，主(zhu)要(yao)特點(dian)(dian)是(shi)將所發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)能直(zhi)接輸送到電(dian)(dian)(dian)(dian)網(wang)(wang)，由(you)電(dian)(dian)(dian)(dian)網(wang)(wang)統一(yi)(yi)(yi)調配向用(yong)戶供電(dian)(dian)(dian)(dian)。但(dan)這種(zhong)電(dian)(dian)(dian)(dian)站(zhan)投資(zi)大(da)、建(jian)(jian)設(she)周期(qi)長、占地面(mian)積大(da)，太(tai)陽(yang)能發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)板多少錢一(yi)(yi)(yi)平(ping)米，發(fa)(fa)(fa)展難度(du)(du)較大(da)。而分散式(shi)小型并網(wang)(wang)發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)系(xi)統，特別是(shi)光(guang)伏建(jian)(jian)筑一(yi)(yi)(yi)體化發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)系(xi)統，由(you)于投資(zi)小、建(jian)(jian)設(she)快、占地面(mian)積小、政策支持力度(du)(du)大(da)等優(you)點(dian)(dian)，是(shi)并網(wang)(wang)發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)的(de)(de)主(zhu)流。

太陽能發電的優點：

1、太陽(yang)能光伏(fu)發(fa)電(dian)進程無(wu)需(xu)冷卻水(shui)，可(ke)以裝置在沒有水(shui)的荒涼沙(sha)漠上。光伏(fu)發(fa)電(dian)還(huan)可(ke)以很便利地(di)與修建(jian)(jian)物連(lian)系，組成光伏(fu)修建(jian)(jian)一體化(hua)發(fa)電(dian)系統，不需(xu)求(qiu)獨自占地(di)，可(ke)節流珍貴(gui)的地(di)盤資源。

2、太陽能(neng)電池組件構造(zao)簡略，體積(ji)小，分量輕，便于運輸(shu)和裝置(zhi)。光伏發(fa)電系(xi)統建(jian)立周期短(duan)，而用依據(ju)用電負荷(he)容量可大(da)可小，便利靈敏，極易合、擴容。
