輸出功率相對小,規模可靈活調整
The output power is relatively small, and the scale can be flexibly adjusted
分布式光伏發電項目的容量在數千瓦至數兆瓦之間,輸出功率遠遠小于大型地面光伏電站;可通過光伏發電的模塊化設計調整規模的大小;可根據屋頂面積與建設條件等因素調整光伏系統的容量;安裝方式相對靈活,適合在耗能集中區域進行分散式建設。
The capacity of distributed photovoltaic power generation projects ranges from several kilowatts to several megawatts, and the output power is much smaller than that of large ground photovoltaic power plants; The scale can be adjusted through the modular design of photovoltaic power generation; The capacity of the photovoltaic system can be adjusted based on factors such as roof area and construction conditions; The installation method is relatively flexible and suitable for decentralized construction in areas with concentrated energy consumption.
項目污染少,環保效益突出
The project has less pollution and outstanding environmental benefits
分布式光伏發電與其他新能源項目相同,在發電的過程中沒有污染和噪音,也不會對空氣和水造成污染,適合在宜居的城市偏遠地區發展,也是防治霧霾和實現節能減排目標的有效手段之一。
Distributed photovoltaic power generation, like other new energy projects, does not cause pollution or noise during the power generation process, nor does it cause pollution to air and water. It is suitable for development in livable and remote urban areas, and is also an effective means of preventing haze and achieving energy-saving and emission reduction goals.

發電用電并存,輸電線路線損少
Coexistence of power generation and consumption, with low transmission line losses
大型地面光伏發電是升壓接入輸電網,僅作為發電電源參與電網運行,而分布式光伏發電是接入配電網,直接發直接用,且大部分能就地消納。因不需要長距離輸送,因此不存在線損,且直接在配電網消納,利用率普遍高于地面光伏電站。
Large scale ground photovoltaic power generation is connected to the transmission network through boosting voltage, and only serves as a power source to participate in grid operation. Distributed photovoltaic power generation is connected to the distribution network, directly used for power generation, and most of it can be consumed locally. Due to the lack of long-distance transmission, there is no line loss and it is directly consumed in the distribution network, with a utilization rate generally higher than that of ground photovoltaic power plants.
靠近負荷中心,對電網影響不大
Close to the load center, with little impact on the power grid
分布式光伏一般分布在中東部負荷中心區域,直接售電給大型工商業用戶住宅等,不需長距離輸送,節約電網成本,規模一般比地面并網光伏電站小,對電網的頻率電壓波動影響有限。
Distributed photovoltaics are generally distributed in the central and eastern load centers, selling electricity directly to large industrial and commercial residential users, without the need for long-distance transmission, saving power grid costs. The scale is generally smaller than ground connected photovoltaic power stations, and the impact on frequency and voltage fluctuations in the power grid is limited.
節約土地資源與開發成本
Saving land resources and development costs
分布式光伏電站項目不需在集中連片的土地上開發,因此能夠有效節省土地資源,提高閑散屋頂廠房的利用效率。同時,在大型工商企業用電需求日益增長的背景下,業主具有建設分布式光伏電站的積極性,項目開發成本一般低于大型并網光伏電站。
Distributed photovoltaic power station projects do not need to be developed on concentrated and contiguous land, thus effectively saving land resources and improving the utilization efficiency of idle rooftop factories. At the same time, in the context of the increasing demand for electricity by large industrial and commercial enterprises, homeowners have the initiative to build distributed photovoltaic power plants, and project development costs are generally lower than those of large-scale grid connected photovoltaic power plants.
分布式光伏發電站的劣勢
Disadvantages of Distributed Photovoltaic Power Plants
參與主體較多,不確定因素增加
There are many participants and uncertain factors increase
分布式光伏電站涉及屋頂所有者及用能企業較多,在項目實施過程中由于分散性多樣性,派生出的商業模式也不盡相同,其不確定因素普遍多于地面光伏電站項目,比如某些項目可能出現屋頂權屬轉移不可抗力合同風險等不確定因素,因此開發及運營分布式光伏電站比大型并網光伏電站更復雜。
Distributed photovoltaic power plants involve a large number of rooftop owners and energy consuming enterprises. Due to the diversity of dispersion during project implementation, the business models derived from them are also different, and their uncertain factors are generally more than those of ground photovoltaic power plant projects. For example, some projects may encounter uncertain factors such as force majeure contract risks in the transfer of rooftop ownership. Therefore, the development and operation of distributed photovoltaic power plants is more complex than large grid connected photovoltaic power plants.
電費結算效率較低
Low efficiency of electricity bill settlement
目前,分布式光伏電站的電費結算較多采取合同能源管理方式,缺乏催收與履約的保障,受用電企業經營情況影響,回收電費的及時性穩定性值得關注。
At present, the settlement of electricity bills in distributed photovoltaic power stations mostly adopts the method of contract energy management, lacking the guarantee of collection and performance. Due to the impact of the business situation of electricity consuming enterprises, the timely and stable recovery of electricity bills is worth paying attention to.
