　　指既可以將發(fā)電的電力賣出去，又可以自用的電站，占地面積較小，成本較低。以>6MW為分界，如工商企業(yè)廠房屋頂光伏發(fā)電系統(tǒng)、民居屋頂光伏發(fā)電系統(tǒng)。根椐當?shù)厍闆r進行因地制宜的建設，以清潔高效、分散布局和就近利用的原則，充分利用當?shù)氐奶柲苜Y源，替代和減少化石能源的消耗。

　　A power station that can both sell the generated electricity and use it for its own purposes, with a small footprint and low cost. Divided by>6MW, such as rooftop photovoltaic power generation systems for industrial and commercial enterprises and residential buildings. Construct according to local conditions, following the principles of cleanliness, efficiency, decentralized layout, and nearby utilization, fully utilizing local solar energy resources to replace and reduce the consumption of fossil fuels.

　　集中式光伏：專門用于發(fā)電和銷售電力的電站，占地面積較大，成本較高，如大型西北地面光伏發(fā)電系統(tǒng)。具體而言，它將光伏陣列安裝在山地、水面、荒漠等寬闊的地區(qū)，光伏陣列在陽光照射下產(chǎn)生直流電，然后通過逆變器將直流電轉換為交流電，并通過升壓站接入電網(wǎng)。集中式光伏電站通常規(guī)模較大，一般在10MW以上。

　　Centralized photovoltaic: a power station specifically designed for generating and selling electricity, with a large footprint and high cost, such as a large-scale northwest ground photovoltaic power generation system. Specifically, it installs photovoltaic arrays in wide areas such as mountains, water surfaces, and deserts. The photovoltaic arrays generate direct current under sunlight, which is then converted into alternating current through an inverter and connected to the grid through a booster station. Centralized photovoltaic power plants are usually large in scale, generally above 10MW.

　　A technology that utilizes the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy.

　　這種技術的關鍵元件是太陽能電池。

　　The key component of this technology is solar cells.

　　太陽能電池經(jīng)過串聯(lián)后進行封裝保護而形成大面積的太陽電池組件，再配合上功率控制器等部件就形成了光伏發(fā)電裝置。

　　After being connected in series, solar cells are packaged and protected to form large-area solar cell modules, which are then combined with components such as power controllers to form photovoltaic power generation devices.
