输出功率相对较小

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。

Traditional centralized power plants can easily reach hundreds of thousands or even millions of kilowatts, and their large-scale application has improved their economic efficiency. The modular design of photovoltaic power generation determines whether its scale can be large or small, and the capacity of the photovoltaic system can be adjusted according to the requirements of the site. Generally speaking, the capacity of a distributed photovoltaic power plant project is within several thousand kilowatts. Unlike centralized power stations, the size of photovoltaic power stations has little impact on power generation efficiency, so their economic impact is also minimal. The investment return rate of small photovoltaic systems is not lower than that of large ones.

污染小，环保效益突出。

Low pollution, 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。

Distributed photovoltaic power station projects have no noise during the power generation process and will not cause pollution to air and water. However, it is necessary to pay attention to the coordinated development of distributed photovoltaics and the surrounding urban environment, and when utilizing clean energy, consider the public's concern for the beauty of the urban environment.

能够在一定程度上缓解局地的用电紧张状况

It can alleviate the local electricity shortage to a certain extent

分布式光伏电站在白天出力最高，正好在这个时段人们对电力的需求最大。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 during the day, coinciding with the highest demand for electricity among people. However, the energy density of distributed photovoltaic power stations is relatively low, with a power output of only about 100 watts per square meter of the distributed photovoltaic power station system. Coupled with the limitation of the roof area of buildings suitable for installing photovoltaic modules, distributed photovoltaic power stations cannot fundamentally solve the problem of electricity shortage.
