多(duo)晶(jing)(jing)基太陽(yang)能(neng)電(dian)(dian)池(chi)(chi)板(ban)(ban)(ban)的效(xiao)率通常為(wei)14-16％。由于(yu)(yu)硅(gui)純度(du)較低(di)(di)，太陽(yang)能(neng)組件功率，多(duo)晶(jing)(jing)太陽(yang)能(neng)電(dian)(dian)池(chi)(chi)板(ban)(ban)(ban)的效(xiao)率不(bu)如單(dan)晶(jing)(jing)太陽(yang)能(neng)電(dian)(dian)池(chi)(chi)板(ban)(ban)(ban)。降低(di)(di)空間(jian)效(xiao)率。您通常需要覆蓋更(geng)大(da)的表(biao)面以(yi)輸出與使(shi)用單(dan)晶(jing)(jing)硅(gui)制成(cheng)的太陽(yang)能(neng)電(dian)(dian)池(chi)(chi)板(ban)(ban)(ban)相同(tong)的電(dian)(dian)力。然而，這并不(bu)意味(wei)著每個單(dan)晶(jing)(jing)硅(gui)太陽(yang)能(neng)電(dian)(dian)池(chi)(chi)板(ban)(ban)(ban)的性能(neng)都優于(yu)(yu)基于(yu)(yu)多(duo)晶(jing)(jing)硅(gui)的那些(xie)。單(dan)晶(jing)(jing)和薄膜太陽(yang)能(neng)電(dian)(dian)池(chi)(chi)板(ban)(ban)(ban)往往在(zai)美學(xue)上更(geng)令人愉(yu)悅，因為(wei)與多(duo)晶(jing)(jing)硅(gui)的斑點藍色相比(bi)，它們具有(you)更(geng)均(jun)勻的外(wai)觀。
