隨著全球?qū)沙掷m(xù)發(fā)展的關(guān)注不斷增加，分布式光伏發(fā)電作為一種清潔、高效的能源解決方案，正逐漸成為能源轉(zhuǎn)型的重要組成部分。它不僅有助于減少對(duì)傳統(tǒng)化石燃料的依賴，還為實(shí)現(xiàn)碳中和目標(biāo)提供了有力支持。

With the increasing global attention to sustainable development, distributed photovoltaic power generation, as a clean and efficient energy solution, is gradually becoming an important component of energy transformation. It not only helps reduce dependence on traditional fossil fuels, but also provides strong support for achieving carbon neutrality goals.

　　一、分布式光伏發(fā)電的原理與優(yōu)勢(shì)

1、 Principles and advantages of distributed photovoltaic power generation

　　分布式光伏發(fā)電系統(tǒng)是一種利用太陽(yáng)能光伏電池將太陽(yáng)光直接轉(zhuǎn)化為電能的發(fā)電方式。其核心原理是“光伏效應(yīng)”，即當(dāng)太陽(yáng)光照射到半導(dǎo)體材料（如硅）時(shí)，光子激發(fā)半導(dǎo)體中的電子，從而產(chǎn)生電流。這種發(fā)電方式具有顯著的優(yōu)勢(shì)，包括：

Distributed photovoltaic power generation system is a power generation method that uses solar photovoltaic cells to directly convert sunlight into electrical energy. The core principle is the "photovoltaic effect", which means that when sunlight shines on semiconductor materials (such as silicon), photons excite electrons in the semiconductor, thereby generating an electric current. This power generation method has significant advantages, including:

　　就地發(fā)電與消納：分布式光伏發(fā)電系統(tǒng)通常安裝在用戶場(chǎng)地附近，所發(fā)電力可以直接用于滿足用戶自身需求，多余電量再接入電網(wǎng)。這種方式減少了電力在長(zhǎng)途傳輸中的損耗，提高了能源利用效率。

On site power generation and consumption: Distributed photovoltaic power generation systems are usually installed near user sites, and the generated electricity can be directly used to meet the user's own needs, with excess electricity then connected to the grid. This method reduces the loss of electricity during long-distance transmission and improves energy utilization efficiency.

　　靈活性高：分布式光伏發(fā)電系統(tǒng)可以根據(jù)場(chǎng)地條件和用戶需求靈活設(shè)計(jì)和安裝，適用于各種規(guī)模和場(chǎng)景，從家庭屋頂?shù)酱笮凸ど虡I(yè)建筑。

High flexibility: Distributed photovoltaic power generation systems can be flexibly designed and installed according to site conditions and user needs, suitable for various scales and scenarios, from household rooftops to large industrial and commercial buildings.

　　環(huán)境友好：光伏發(fā)電過(guò)程中不產(chǎn)生溫室氣體排放，是一種真正的清潔能源。在平均日照條件下，1千瓦分布式光伏系統(tǒng)每年可減少約1噸二氧化碳排放。

Environmentally friendly: Photovoltaic power generation does not produce greenhouse gas emissions and is a truly clean energy source. Under average sunlight conditions, a 1 kW distributed photovoltaic system can reduce approximately 1 ton of carbon dioxide emissions annually.

（1） In the field of industry and commerce

　　工商業(yè)建筑的屋頂面積大，光照條件好，是分布式光伏發(fā)電的理想場(chǎng)所。例如，義烏城投金福源停車樓屋頂分布式光伏發(fā)電項(xiàng)目，通過(guò)在停車樓屋頂安裝光伏板，不僅為車輛遮陽(yáng)擋雨，還為停車樓提供了綠色電能。該項(xiàng)目預(yù)計(jì)年均發(fā)電量達(dá)66.3萬(wàn)千瓦時(shí)，每年可減少碳排放量498.26噸。

The large roof area and good lighting conditions of industrial and commercial buildings make them ideal places for distributed photovoltaic power generation. For example, the Yiwu City Investment Jinfuyuan Parking Building Roof Distributed Photovoltaic Power Generation Project installs photovoltaic panels on the roof of the parking building, which not only provides shade and rain protection for vehicles, but also provides green electricity for the parking building. The project is expected to generate an average annual power of 663000 kilowatt hours and reduce carbon emissions by 498.26 tons annually.

（2） Rural and Family

　　農(nóng)村地區(qū)和家庭住宅也是分布式光伏發(fā)電的重要應(yīng)用場(chǎng)景。通過(guò)安裝小型光伏系統(tǒng)，用戶可以實(shí)現(xiàn)自發(fā)自用，余電上網(wǎng)。這種模式不僅降低了用戶的用電成本，還為電網(wǎng)提供了額外的清潔能源。例如，山東某村莊通過(guò)安裝防逆流并網(wǎng)箱，將50戶家庭的光伏發(fā)電系統(tǒng)連接到電網(wǎng)，顯著提高了家庭對(duì)光伏發(fā)電的自消納能力。

Rural areas and residential homes are also important application scenarios for distributed photovoltaic power generation. By installing a small photovoltaic system, users can achieve self use and connect surplus electricity to the grid. This model not only reduces users' electricity costs, but also provides additional clean energy for the power grid. For example, a village in Shandong Province connected the photovoltaic power generation systems of 50 households to the grid by installing anti backflow and net cages, significantly improving the self consumption capacity of households for photovoltaic power generation.

（3） Public facilities

　　分布式光伏發(fā)電系統(tǒng)還可以應(yīng)用于公共設(shè)施，如學(xué)校、醫(yī)院和污水處理廠等。溫嶺市某污水處理廠通過(guò)安裝分布式光伏發(fā)電系統(tǒng)，不僅滿足了自身部分用電需求，還降低了運(yùn)營(yíng)成本。

Distributed photovoltaic power generation systems can also be applied to public facilities such as schools, hospitals, and sewage treatment plants. A sewage treatment plant in Wenling City has installed a distributed photovoltaic power generation system, which not only meets some of its own electricity needs but also reduces operating costs.
