IC693NIU004
IC693NIU004IC693NIU004一個光伏系統(tǒng)設計者的第一項工作是確定系統(tǒng)的負載。這些負載估算是設計獨立光伏系統(tǒng)的成本的重要因素之一。一個電器所需的功率可以測量出來或由制造商提供。然后把電器每日,每周,每月所用的時間估算出來。對戶用系統(tǒng)(和其它許多系統(tǒng))負載所用的時間是可以控制的。實際上,每個電器所估算使用時間須再加裕量(如10%等),不過這將增加光伏系統(tǒng)的規(guī)格和成本。 如果使用直流負載如直流節(jié)能燈等,就可以避免直流變交流的這部分損失效率高,使用壽命長,而交流電器種類繁多,但效率通常較低。
對獨立光做系統(tǒng)的工作電壓的選擇決定于負載所需的電壓和總的電流。
