1. The output power is relatively small

传统的集中式电站动辄几十万千瓦，甚至几百万千瓦，规模化的应用提高了其经济性。光伏发电的模块化设计，决定了其规模可大可小，可根据场地的要求调整光伏系统的容量。一般而言，一个分布式光伏电站项目的容量在数千千瓦以内。与集中式电站不同，光伏电站的大小对发电效率的影响很小，因此对其经济性的影响也很小，小型光伏系统的投资收益率并不会比大型的低。

The traditional centralized power station is often hundreds of thousands of kilowatts, even hundreds of thousands of kilowatts. Its large-scale application has improved its economy. The modular design of photovoltaic power generation determines whether its scale can be large or small, and the capacity of photovoltaic system can be adjusted according to the requirements of the site. Generally speaking, the capacity of a distributed photovoltaic power station project is within thousands of kilowatts. Unlike centralized power stations, the size of photovoltaic power stations has a small impact on power generation efficiency, so it has a small impact on its economy. The return on investment of small photovoltaic systems is not lower than that of large ones.

2、污染小，环保效益突出

2. Low pollution and outstanding environmental benefits

分布式光伏电站项目在发电过程中，没有噪声，也不会对空气和水产生污染。但是，需要重视分布式光伏与周边城市环境的协调发展，在利用清洁能源的时候，考虑民众对城市环境美感的关切。

During the power generation process of distributed photovoltaic power station project, there is no noise and no pollution to air and water. However, it is necessary to pay attention to the coordinated development of distributed photovoltaic and the surrounding urban environment, and consider the public's concern about the beauty of the urban environment when using clean energy.

3、能够在一定程度上缓解局地的用电紧张状况

3. It can alleviate the local power tension to a certain extent

分布式光伏电站在白天出力高，正好在这个时段人们对电力的需求大。但是，分布式光伏电站的能量密度相对较低，每平方米分布式光伏电站系统的功率仅约100瓦，再加上适合安装光伏组件的建筑屋顶面积的限制，因此分布式光伏电站不能从根本上解决用电紧张问题。

Distributed photovoltaic power stations have the highest output in the daytime, which is the time when people demand the most power. However, the energy density of distributed photovoltaic power stations is relatively low, and the power of each square meter of distributed photovoltaic power station system is only about 100 watts. In addition to the limitation of the roof area of buildings suitable for installing photovoltaic modules, distributed photovoltaic power stations cannot fundamentally solve the problem of power shortage.

分布式光伏电站通常是指利用分散式资源，装机规模较小的、布置在用户附近的发电系统，它一般接入低于35千伏或更低电压等级的电网。分布式光伏电站特指采用光伏组件，将太阳能直接转换为电能的分布式光伏电站系统。

Distributed photovoltaic power stations usually refer to power generation systems that utilize distributed resources, have small installed capacity and are arranged near users. They are generally connected to power grids with voltage levels lower than 35 kV or lower. Distributed photovoltaic power station refers to a distributed photovoltaic power station system that uses photovoltaic modules to directly convert solar energy into electric energy.
