太陽能(neng)光(guang)伏發電具有十分明顯的優勢。一是(shi)資(zi)源(yuan)豐(feng)富，且不會枯竭，是(shi)可(ke)再生清(qing)潔能(neng)源(yuan)。特(te)別是(shi)光(guang)伏發電過程不耗水(shui)，光(guang)伏電站(zhan)建(jian)(jian)設(she)不受(shou)水(shui)資(zi)源(yuan)制約，可(ke)以在(zai)任何空閑土地(di)上、特(te)別是(shi)可(ke)以在(zai)沙(sha)漠土地(di)上建(jian)(jian)設(she)光(guang)伏電站(zhan)。二是(shi)光(guang)伏電池(chi)安(an)裝建(jian)(jian)設(she)簡(jian)單，裝機規模靈活(huo)，運行管(guan)理方便(bian)，既可(ke)以利用空曠場地(di)進(jin)行建(jian)(jian)設(she)，也可(ke)以與建(jian)(jian)筑結合建(jian)(jian)設(she)，幾乎不需要進(jin)行運行維護，開發利用的潛(qian)力很大(da)。
