Distributed photovoltaic power generation specifically refers to a photovoltaic power generation facility built near the user's site, operating in a way that is characterized by spontaneous self use on the user's side, excess electricity connected to the grid, and balanced adjustment in the distribution system. Distributed photovoltaic power generation follows the principles of adapting to local conditions, clean and efficient, decentralized layout, and nearby utilization, fully utilizing local solar energy resources to replace and reduce fossil energy consumption.

分布式光伏发电特指采用光伏组件，将太阳能直接转换为电能的分布式发电系统。它是一种新型的、具有广阔发展前景的发电和能源综合利用方式，它倡导就近发电，就近并网，就近转换，就近使用的原则，不仅能够有效提高同等规模光伏电站的发电量，同时还有效解决了电力在升压及长途运输中的损耗问题。

Distributed photovoltaic power generation specifically refers to a distributed power generation system that uses photovoltaic modules to directly convert solar energy into electrical energy. It is a new and promising method of power generation and energy comprehensive utilization. It advocates the principle of nearby power generation, grid connection, conversion, and use. It not only effectively increases the power generation of photovoltaic power plants of the same scale, but also solves the problem of power loss during boosting and long-distance transportation.

目前应用为广泛的分布式光伏发电系统，是建在城市建筑物屋顶的光伏发电项目。该类项目必须接入公共电网，与公共电网一起为附近的用户供电。

The most widely used distributed photovoltaic power generation system is currently a photovoltaic power generation project built on the roof of urban buildings. This type of project must be connected to the public power grid and supply power to nearby users together with the public power grid.

分布式光伏发电系统，又称分散式发电或分布式供能，是指在用户现场或靠近用电现场配置较小的光伏发电供电系统，以满足特定用户的需求，支持现存配电网的经济运行，或者同时满足这两个方面的要求。

Distributed photovoltaic power generation system, also known as distributed power generation or distributed energy supply, refers to the configuration of smaller photovoltaic power generation and supply systems on or near the user site to meet the needs of specific users, support the economic operation of existing distribution networks, or meet both requirements.

分布式光伏发电系统的基本设备包括光伏电池组件、光伏方阵支架、直流汇流箱、直流配电柜、并网逆变器、交流配电柜等设备，另外还有供电系统监控装置和环境监测装置。其运行模式是在有太阳辐射的条件下，光伏发电系统的太阳能电池组件阵列将太阳能转换输出的电能，经过直流汇流箱集中送入直流配电柜，由并网逆变器逆变成交流电供给建筑自身负载，多余或不足的电力通过联接电网来调节。

The basic equipment of a distributed photovoltaic power generation system includes photovoltaic cell components, photovoltaic array brackets, DC combiner boxes, DC distribution cabinets, grid connected inverters, AC distribution cabinets, and other equipment. In addition, there are power supply system monitoring devices and environmental monitoring devices. Its operating mode is that under the condition of solar radiation, the solar cell module array of the photovoltaic power generation system converts the solar energy into output electricity, which is sent to the DC distribution cabinet through the DC combiner box. The current is inverted by the grid connected inverter to supply the building's own load, and the excess or insufficient electricity is adjusted by connecting to the grid.
