工商業(yè)屋頂光伏并網(wǎng)方式主要有以下幾種：

　　There are several main ways to connect industrial and commercial rooftop photovoltaics to the grid:

　　自發(fā)自用余電上網(wǎng)模式 ：

　　Self use surplus electricity grid connection mode:

　　定義 ：光伏系統(tǒng)產(chǎn)生的電能優(yōu)先供企業(yè)自用，多余的電量則并入電網(wǎng)。

　　Definition: The electricity generated by photovoltaic systems is prioritized for the enterprise's own use, and excess electricity is incorporated into the power grid.

　　適用場景 ：適用于白天用電量較大的廠房，自用比例越高，成本回收周期越短。

　　Applicable scenarios: Suitable for factories with high electricity consumption during the day, the higher the proportion of self use, the shorter the cost recovery cycle.

　　優(yōu)點 ：能夠減少企業(yè)的電費開支，并充分利用光伏電能在用電高峰時段。

　　Advantages: It can reduce the electricity expenses of enterprises and fully utilize photovoltaic energy during peak periods of electricity consumption.

　　全額上網(wǎng)模式 ：

　　Full internet access mode:

　　定義 ：光伏系統(tǒng)產(chǎn)生的所有電能全部賣給電網(wǎng)公司。

　　Definition: All electrical energy generated by a photovoltaic system is sold to the power grid company.

　　適用場景 ：適用于大型集中式光伏電站，尤其是自身用電需求較低的情況。

　　Applicable scenarios: Suitable for large centralized photovoltaic power plants, especially those with low electricity demand.

　　優(yōu)點 ：企業(yè)可以節(jié)省電費，且管理維護相對簡單。

　　Advantages: Enterprises can save electricity costs and have relatively simple management and maintenance.

　　全部自用模式 ：

　　All self use mode:

　　定義 ：光伏系統(tǒng)產(chǎn)生的所有電能全部供企業(yè)自用，不并入電網(wǎng)。

　　Definition: All electrical energy generated by photovoltaic systems is for the sole use of the enterprise and is not integrated into the power grid.

　　適用場景 ：適用于特別偏遠、交通不方便且用電量較大的地區(qū)，如農(nóng)業(yè)和養(yǎng)殖業(yè)。

　　Applicable scenarios: Suitable for particularly remote areas with inconvenient transportation and high electricity consumption, such as agriculture and animal husbandry.

　　優(yōu)點 ：確保企業(yè)能夠完全自主地使用所有產(chǎn)生的電能，但需要配備較大容量的儲能設備。

　　Advantages: Ensure that the enterprise can fully autonomously use all generated electricity, but requires larger capacity energy storage equipment.

　　并網(wǎng)流程

　　Grid Connection Process

　　提交并網(wǎng)申請 ：

　　Submit grid connection application:

　　企業(yè)需要向當?shù)仉娋W(wǎng)公司提交并網(wǎng)申請，并提供必要的材料，如企業(yè)營業(yè)執(zhí)照、稅務登記證、土地證等。

　　Enterprises need to submit grid connection applications to the local power grid company and provide necessary materials, such as business license, tax registration certificate, land certificate, etc.

　　現(xiàn)場勘查 ：

　　On site investigation:

　　當?shù)毓╇姽緦才湃藛T到項目現(xiàn)場進行勘查，確定接入系統(tǒng)的具體方案。

　　The local power supply company will arrange personnel to conduct an investigation at the project site to determine the specific plan for connecting to the system.

　　制定接入系統(tǒng)方案 ：

　　Develop an access system plan:

　　供電公司根據(jù)勘查結(jié)果和國家相關(guān)技術(shù)標準，制定接入系統(tǒng)方案，并通過書面形式回復企業(yè)。

　　The power supply company shall develop an access system plan based on the survey results and relevant national technical standards, and reply to the enterprise in writing.

　　安裝設備 ：

　　Installation equipment:

　　企業(yè)需要安裝逆變器、計量裝置等并網(wǎng)設備，并確保設備符合相關(guān)標準和規(guī)范。

　　Enterprises need to install grid connected equipment such as inverters and measuring devices, and ensure that the equipment complies with relevant standards and specifications.

　　簽訂并網(wǎng)合同 ：

　　Sign the grid connection contract:

　　企業(yè)需要與售電公司簽訂并網(wǎng)合同，明確發(fā)電量、電價、補貼等條款。

　　Enterprises need to sign grid connection contracts with power sales companies, specifying terms such as power generation, electricity prices, subsidies, etc.

　　系統(tǒng)調(diào)試與運行 ：

　　System debugging and operation:

　　完成設備安裝后，進行系統(tǒng)調(diào)試，確保所有設備正常運行，并與電網(wǎng)進行正式并網(wǎng)。

　　After completing the installation of the equipment, perform system debugging to ensure that all devices operate normally and are officially connected to the power grid.

　　建議

　　Suggestion

　　根據(jù)用電需求和條件選擇合適的并網(wǎng)模式 ：企業(yè)應根據(jù)自身的用電量、用電時間和電價等因素，選擇最適合自己的并網(wǎng)模式。

　　Select the appropriate grid connection mode based on electricity demand and conditions: Enterprises should choose the most suitable grid connection mode based on their own electricity consumption, electricity consumption time, electricity price, and other factors.

　　咨詢專業(yè)公司 ：在實施并網(wǎng)項目前，建議咨詢專業(yè)的光伏系統(tǒng)集成商或電力公司，以確保項目的順利實施和運營。

　　Consulting a professional company: Before implementing the grid connection project, it is recommended to consult a professional photovoltaic system integrator or power company to ensure the smooth implementation and operation of the project.

　　關(guān)注政策變化 ：不同地區(qū)的并網(wǎng)政策和補貼可能有所不同，企業(yè)應及時了解并遵循當?shù)卣摺?/p>

　　Pay attention to policy changes: The grid connection policies and subsidies may vary in different regions, and companies should promptly understand and follow local policies.

　　通過以上方式，工商業(yè)屋頂光伏電站可以實現(xiàn)高效、經(jīng)濟的能源利用，為企業(yè)帶來顯著的經(jīng)濟效益和環(huán)境效益。

　　Through the above methods, commercial rooftop photovoltaic power stations can achieve efficient and economical energy utilization, bringing significant economic and environmental benefits to enterprises.
