在“雙碳”目標(biāo)驅(qū)動下，工商業(yè)光伏發(fā)電已成為企業(yè)降本增效、綠色轉(zhuǎn)型的重要路徑。其合作模式呈現(xiàn)多元化特征，企業(yè)可根據(jù)自身資源稟賦、用電特性及投資偏好，選擇最適宜的參與方式。

　　Driven by the "dual carbon" goal, commercial and industrial photovoltaic power generation has become an important path for enterprises to reduce costs, increase efficiency, and undergo green transformation. Its cooperation mode presents diversified characteristics, and enterprises can choose the most suitable participation method based on their own resource endowment, electricity consumption characteristics, and investment preferences.

　　一、自發(fā)自用+余電上網(wǎng)模式

　　1、 Spontaneous self use+surplus electricity grid connection mode

　　該模式由企業(yè)自主投資建設(shè)光伏電站，所發(fā)電量優(yōu)先供自身生產(chǎn)使用，多余電量并入電網(wǎng)獲取收益。某制造業(yè)企業(yè)案例顯示，其屋頂光伏年發(fā)電量中，75%用于沖抵生產(chǎn)用電，剩余25%通過“全額上網(wǎng)”獲得電價(jià)收入。此模式核心優(yōu)勢在于：

　　This model involves the independent investment and construction of photovoltaic power stations by enterprises, with the generated electricity being prioritized for their own production and use, and excess electricity being incorporated into the power grid to generate revenue. A case study of a manufacturing enterprise shows that 75% of its annual rooftop photovoltaic power generation is used to offset production electricity, while the remaining 25% earns electricity price income through "full grid connection". The core advantages of this model are:

　　用電成本直降：光伏發(fā)電成本普遍低于工商業(yè)峰谷電價(jià)，某園區(qū)企業(yè)測算表明，自發(fā)自用比例每提升10%，綜合電價(jià)下降。

　　Direct reduction in electricity costs: The cost of photovoltaic power generation is generally lower than the peak and valley electricity prices of industry and commerce. According to calculations by a certain park enterprise, for every 10% increase in the proportion of self use, the comprehensive electricity price decreases.

　　碳資產(chǎn)管理價(jià)值：通過綠證交易及碳減排量核證，企業(yè)可額外獲得環(huán)境權(quán)益收益。某出口型企業(yè)通過CCER項(xiàng)目年增收。

　　Carbon asset management value: Through green certificate trading and carbon emission reduction verification, enterprises can obtain additional environmental equity benefits. A certain export-oriented enterprise has increased its annual revenue through the CCER project.

　　二、合同能源管理模式（EMC）

　　2、 Contract Energy Management Model (EMC)

　　能源服務(wù)公司（ESCO）與企業(yè)簽訂節(jié)能服務(wù)合同，全額投資建設(shè)光伏電站，雙方按約定比例分享節(jié)能收益。典型合作周期為15-25年，期滿后電站無償移交企業(yè)。某物流園區(qū)項(xiàng)目數(shù)據(jù)顯示，ESCO通過電價(jià)折扣模式收取服務(wù)費(fèi)，企業(yè)實(shí)際用電成本降低。此模式特點(diǎn)為：

　　Energy service companies (ESCOs) sign energy-saving service contracts with enterprises, fully invest in the construction of photovoltaic power plants, and both parties share energy-saving benefits according to the agreed proportion. The typical cooperation period is 15-25 years, after which the power station will be transferred to the enterprise free of charge. Data from a logistics park project shows that ESCO charges service fees through electricity price discount models, resulting in a reduction in the actual electricity costs of the enterprise. The characteristics of this mode are:

　　零投資啟動：企業(yè)無需承擔(dān)初期建設(shè)成本，適合資本預(yù)算緊張的企業(yè)。

　　Zero investment start-up: Enterprises do not need to bear initial construction costs, suitable for enterprises with tight capital budgets.

　　專業(yè)運(yùn)維保障：ESCO負(fù)責(zé)全生命周期運(yùn)維，某第三方機(jī)構(gòu)監(jiān)測表明，專業(yè)運(yùn)維使系統(tǒng)效率提升。

　　Professional operation and maintenance guarantee: ESCO is responsible for the entire lifecycle operation and maintenance. Monitoring by a third-party organization shows that professional operation and maintenance improve system efficiency.

　　三、融資租賃+經(jīng)營性租賃模式

　　3、 Financial leasing+operating leasing model

　　通過金融工具降低企業(yè)投資門檻，常見方式包括：

　　Common ways to lower the investment threshold for enterprises through financial instruments include:

　　直接租賃：企業(yè)選定設(shè)備后，租賃公司采購并出租，企業(yè)分期支付租金，期末獲得設(shè)備所有權(quán)。某食品加工企業(yè)采用該模式，初始投資僅占項(xiàng)目總投資的。

　　Direct leasing: After the enterprise selects the equipment, the leasing company purchases and leases it, and the enterprise pays the rent in installments, obtaining ownership of the equipment at the end of the period. A certain food processing enterprise adopts this model, and the initial investment only accounts for a proportion of the total project investment.

　　經(jīng)營性租賃：企業(yè)按使用電量支付租金，租賃公司享有設(shè)備所有權(quán)及補(bǔ)貼收益。某商業(yè)綜合體案例顯示，該模式使企業(yè)資產(chǎn)負(fù)債率降低。

　　Operating leasing: Enterprises pay rent based on electricity usage, and leasing companies enjoy ownership of equipment and subsidy income. A case study of a commercial complex shows that this model reduces the asset liability ratio of the enterprise.

　　四、隔墻售電+虛擬電廠模式

　　4、 Wall mounted electricity sales+virtual power plant mode

　　在分布式發(fā)電市場化交易試點(diǎn)區(qū)域，企業(yè)可通過“隔墻售電”將電量直接售給周邊用戶，或參與虛擬電廠聚合交易。某工業(yè)園區(qū)實(shí)踐表明，點(diǎn)對點(diǎn)交易電價(jià)較標(biāo)桿電價(jià)上浮，顯著提升項(xiàng)目收益率。此模式需關(guān)注：

　　In the pilot area for market-oriented trading of distributed power generation, enterprises can directly sell electricity to surrounding users through "wall sales" or participate in virtual power plant aggregation trading. Practice in a certain industrial park has shown that peer-to-peer transaction electricity prices are higher than benchmark electricity prices, significantly improving project profitability. This mode requires attention to:

　　輸配電價(jià)核定：需明確過網(wǎng)費(fèi)分?jǐn)倷C(jī)制，避免交易成本過高。

　　Determination of transmission and distribution electricity prices: It is necessary to clarify the mechanism for sharing network fees to avoid excessive transaction costs.

　　電力市場準(zhǔn)入：需符合當(dāng)?shù)亟灰滓?guī)則，某試點(diǎn)省份要求單體項(xiàng)目容量不低于。

　　Electricity market access: It must comply with local trading rules, and a pilot province requires that the capacity of individual projects be no less than.

　　五、產(chǎn)業(yè)園區(qū)綜合能源服務(wù)模式

　　5、 Comprehensive energy service model for industrial parks

　　在產(chǎn)業(yè)園區(qū)層面，通過“光伏+儲能+充電樁+智慧能源管理”一體化方案，實(shí)現(xiàn)多能互補(bǔ)與需求響應(yīng)。某高新區(qū)示范項(xiàng)目數(shù)據(jù)顯示，通過峰谷套利及需求側(cè)響應(yīng)，綜合能效提升。此模式關(guān)鍵要素包括：

　　At the level of industrial parks, the integrated solution of "photovoltaic+energy storage+charging piles+smart energy management" is used to achieve multi energy complementarity and demand response. Data from a demonstration project in a certain high-tech zone shows that comprehensive energy efficiency has been improved through peak valley arbitrage and demand side response. The key elements of this model include:

　　微電網(wǎng)建設(shè)：構(gòu)建局域電網(wǎng)實(shí)現(xiàn)能源自平衡，某園區(qū)微電網(wǎng)使光伏消納率提升。

　　Microgrid construction: Building a local power grid to achieve energy self balance, and a microgrid in a certain park to increase the photovoltaic consumption rate.

　　碳足跡追溯系統(tǒng)：通過區(qū)塊鏈技術(shù)記錄全生命周期碳數(shù)據(jù)，助力企業(yè)綠色認(rèn)證。

　　Carbon Footprint Traceability System: Using blockchain technology to record carbon data throughout the entire lifecycle, helping enterprises achieve green certification.

　　模式選擇的核心考量

　　Core considerations for mode selection

　　企業(yè)決策需綜合評估：

　　Enterprise decision-making requires comprehensive evaluation:

　　用電負(fù)荷特性：連續(xù)型負(fù)荷（如24小時(shí)生產(chǎn)）適宜高自發(fā)自用比例，間歇型負(fù)荷需配套儲能。

　　Power load characteristics: Continuous loads (such as 24-hour production) are suitable for high spontaneous self use ratios, while intermittent loads require energy storage.

　　屋頂資源條件：彩鋼瓦屋頂需采用柔性支架，混凝土屋頂適合BIPV/BAPV方案。

　　Roof resource conditions: Color steel tile roofs require flexible supports, while concrete roofs are suitable for BIPV/BAPV schemes.

　　政策合規(guī)性：需核查建筑荷載、消防規(guī)范及電力接入要求，某企業(yè)因未辦理并網(wǎng)手續(xù)導(dǎo)致項(xiàng)目延期。

　　Policy compliance: It is necessary to verify the building load, fire safety regulations, and power access requirements. A certain enterprise caused a project delay due to failure to complete grid connection procedures.

　　工商業(yè)光伏發(fā)電合作模式正從單一投資向綜合能源服務(wù)演進(jìn)，企業(yè)需結(jié)合戰(zhàn)略定位、財(cái)務(wù)狀況及能源需求，選擇最優(yōu)化方案。隨著電力市場化改革深化及綠色金融創(chuàng)新，光伏發(fā)電將深度融入企業(yè)ESG體系，成為實(shí)現(xiàn)碳中和目標(biāo)的核心抓手。

　　The cooperation mode of industrial and commercial photovoltaic power generation is evolving from single investment to comprehensive energy services. Enterprises need to choose the optimal solution based on their strategic positioning, financial situation, and energy demand. With the deepening of electricity marketization reform and innovation in green finance, photovoltaic power generation will be deeply integrated into the corporate ESG system, becoming the core lever for achieving carbon neutrality goals.
