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.

分布式光伏發電特指采用光伏組件，將太陽能直接轉換為電能的分布式發電系統。它是一種新型的、具有廣闊發展前景的發電和能源綜合利用方式，它倡導就近發電，就近并網，就近轉換，就近使用的原則，不僅能夠有效提高同等規模光伏電站的發電量，同時還有效解決了電力在升壓及長途運輸中的損耗問題。

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.

目前應用為廣泛的分布式光伏發電系統，是建在城市建筑物屋頂的光伏發電項目。該類項目必須接入公共電網，與公共電網一起為附近的用戶供電。

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.

分布式光伏發電系統，又稱分散式發電或分布式供能，是指在用戶現場或靠近用電現場配置較小的光伏發電供電系統，以滿足特定用戶的需求，支持現存配電網的經濟運行，或者同時滿足這兩個方面的要求。

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.

分布式光伏發電系統的基本設備包括光伏電池組件、光伏方陣支架、直流匯流箱、直流配電柜、并網逆變器、交流配電柜等設備，另外還有供電系統監控裝置和環境監測裝置。其運行模式是在有太陽輻射的條件下，光伏發電系統的太陽能電池組件陣列將太陽能轉換輸出的電能，經過直流匯流箱集中送入直流配電柜，由并網逆變器逆變成交流電供給建筑自身負載，多余或不足的電力通過聯接電網來調節。

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.
