　　指既可以将发电的电力卖出去，又可以自用的电站，占地面积较小，成本较低。以>6MW为分界，如工商企业厂房屋顶光伏发电系统、民居屋顶光伏发电系统。根椐当地情况进行因地制宜的建设，以清洁高效、分散布局和就近利用的原则，充分利用当地的太阳能资源，替代和减少化石能源的消耗。

　　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：专门用于发电和销售电力的电站，占地面积较大，成本较高，如大型西北地面光伏发电系统。具体而言，它将光伏阵列安装在山地、水面、荒漠等宽阔的地区，光伏阵列在阳光照射下产生直流电，然后通过逆变器将直流电转换为交流电，并通过升压站接入电网。集中式光伏电站通常规模较大，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.

　　利用半导体界面的光生伏特效应而将光能直接转变为电能的一种技术。

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

　　这种技术的关键元件是太阳能电池。

　　The key component of this technology is solar cells.

　　太阳能电池经过串联后进行封装保护而形成大面积的太阳电池组件，再配合上功率控制器等部件就形成了光伏发电装置。

　　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.
