Project Overview

As China accelerates its carbon peaking and carbon neutrality agenda, renewable energy enterprises are expected not only to deliver green products but also to establish comprehensive low-carbon operational models and demonstrate practical, scalable pathways toward carbon neutrality for customers, partners, and the public.

Conventional corporate showrooms primarily focus on product displays, offering limited opportunities to showcase real-world energy system operation or integrated sustainability practices. Moreover, most buildings still rely on conventional AC power systems, resulting in limited renewable energy utilization and operational flexibility. These limitations make it difficult to demonstrate the collaborative benefits of integrated energy systems or provide an immersive low-carbon experience.

To address these challenges, GoodWe developed the Eco Smart Home within its Guangde National Net-Zero Industrial Park. Serving simultaneously as a technology validation platform and corporate showcase, the project deeply integrates photovoltaic generation, energy storage, DC power distribution, flexible loads, EV charging, PV-driven air-source heat pumps, and intelligent energy management into an operational building.

Centered on the concept of Generation, Grid, Load, Storage, and Intelligence, the project achieves high renewable energy utilization, low-carbon building operation, and intelligent energy dispatch in a unified system. It also embeds the Company's dual-carbon strategy throughout management, operation, communication, and public engagement, providing a replicable model for sustainable industrial parks and green buildings.

项目背景

随着“双碳”目标持续推进，新能源企业不仅需要提供绿色产品，更需要建立覆盖企业运营全过程的绿色发展模式，并向客户、合作伙伴和社会公众展示可复制、可体验、可推广的零碳实践。然而，传统企业展厅多以产品展示为主，缺少能源系统真实运行场景，无法充分体现企业在绿色治理、低碳运营及技术创新方面的综合能力；同时，建筑自身仍普遍依赖交流供电体系，新能源消纳率和柔性调节能力有限，难以验证源网荷储协同运行效果，也难以形成公众可感知的绿色低碳体验。

基于此，固德威依托广德国家级零碳园区建设源网荷储智小屋，以真实建筑作为技术验证平台和品牌展示窗口，将光伏、储能、直流配电、柔性负荷、充电桩、光伏直驱空气源热泵、智慧能源管理等技术深度融合，打造集绿色办公、技术研发、客户接待、行业交流、公众科普于一体的零碳示范空间。项目以“源网荷储智”协同运行理念为核心，实现绿色能源高比例利用、建筑低碳运行和智慧能源调度同步推进，并将企业双碳理念贯穿管理、运营、展示和传播全过程，为园区和建筑绿色低碳发展提供可复制的实践样板。

Project Implementation

To establish a centralized platform for demonstrating the Company's low-carbon practices, GoodWe formed a cross-functional project team led by senior management and involving the Sustainability Research Institute, R&D Center, Product Center, Brand & Marketing Department, Administration, and Information Technology Department. The Eco Smart Home was designated as a strategic sustainability initiative, supported by a cross-departmental coordination mechanism covering technology development, engineering, operations, and brand communication throughout the project lifecycle.

To improve renewable energy utilization and reduce building energy consumption, the project installed a 108.6 kWp building-integrated photovoltaic (BIPV) system together with a 300 kWh battery energy storage system. An AC/DC hybrid distribution architecture was established, combining a 380 V AC network with 750 V, 375 V, and 220 V DC bus systems. This enables local renewable energy generation, on-site consumption, and flexible energy balancing while significantly improving overall system efficiency through coordinated optimization of electricity and thermal energy.

To minimize energy losses caused by repeated AC/DC power conversion, the project deployed an innovative DC building system. DC lighting, DC EV charging, and DC HVAC equipment are directly connected to the DC bus, reducing conversion stages and improving energy efficiency. Meanwhile, a hybrid AC/DC microgrid integrating photovoltaic generation, energy storage, flexible DC distribution, and intelligent control enables real-time coordination among generation, grid, load, and storage resources, providing a practical demonstration for future power systems.

To enhance operational efficiency, GoodWe independently developed an Energy Management System (EMS), integrating indoor environmental sensors, weather stations, and various energy assets into a unified management platform. Based on weather forecasting, load prediction, and electricity pricing strategies, the EMS dynamically optimizes photovoltaic generation, battery charging and discharging, HVAC operation, lighting, EV charging, and flexible loads. The system maximizes energy efficiency while maintaining occupant comfort and is designed with Virtual Power Plant (VPP) compatibility to support future demand response and electricity market participation.

To strengthen sustainability communication, the Eco Smart Home serves as a dedicated demonstration center for GoodWe's dual-carbon strategy. Interactive exhibition areas present concepts such as renewable energy, carbon neutrality, and integrated PV-storage-DC technologies through digital twin visualization and real-time operational dashboards displaying power generation, battery status, carbon emission reductions, and energy flows. Since its completion, the facility has become an important venue for customer visits, technical exchanges, professional training, and academic tours, significantly enhancing GoodWe's green brand communication.

Internally, the project also functions as a sustainability education platform. GoodWe organizes green office campaigns, Energy Conservation Week, Low-Carbon Day activities, employee training, and guided tours to foster low-carbon awareness. Together with digital initiatives such as the enterprise carbon management platform, product carbon footprint management, and Battery Passport solutions, the project extends sustainability principles across product development, manufacturing, procurement, and supply chain collaboration, forming a closed-loop green governance model spanning technological innovation, corporate management, and industrial collaboration.

项目实施

针对企业绿色低碳实践缺乏集中展示平台的问题，固德威成立由公司管理层统筹，可持续发展研究院、研发中心、产品中心、品牌市场、行政后勤及信息化等部门共同参与的项目团队，将源网荷储智小屋纳入公司绿色发展战略重点项目，建立跨部门协同推进机制，明确技术研发、工程建设、运营管理和品牌传播职责，实现项目全过程管理。

针对建筑运行能耗较高、可再生能源利用率不足的问题，项目建设108.6kWp建筑光伏系统，结合BIPV技术实现建筑与发电系统深度融合，并配置300kWh储能系统，构建交流380V与直流750V、375V、220V三级直流母线相结合的交直流混合配电架构，实现建筑能源就地生产、就地消纳和柔性调节。通过冷热、电能协同优化，大幅提升新能源消纳比例和系统运行效率。

针对传统建筑存在多次交直流变换造成能量损失的问题，项目创新部署直流建筑系统，将直流照明、直流充电、直流暖通等设备直接接入直流母线，减少电能转换环节，提高供电效率。同时构建“光储交直柔”建筑微电网，实现源侧、网侧、荷侧及储能设备实时协同运行，为未来新型电力系统建设提供应用验证。

针对建筑运行依赖人工管理、能源调节效率不足的问题，项目自主研发智慧能源管理系统（EMS），集成室内环境传感器、室外气象站及各类能源设备，实现光伏、储能、暖通、照明、充电设施及柔性负荷统一接入。系统结合天气预测、负荷预测和电价策略，对发电、储能充放电及用能设备进行动态优化调度，在保障室内舒适性的同时实现能源利用效率最大化，并预留虚拟电厂接入能力，为未来需求响应和电力市场参与提供支撑。

针对企业绿色文化传播不足的问题，项目将小屋打造为企业双碳展示窗口，在展示空间系统布置绿色能源、碳中和、光储直柔、能管平台等内容，结合实时能源运行大屏和数字孪生平台，动态展示发电量、储能状态、碳减排量、能源流向等数据，使参观者能够直观了解绿色能源运行全过程。项目建成后已成为客户接待、行业交流、技术培训及高校参访的重要场所，有效提升企业绿色品牌传播能力。

针对绿色低碳理念向企业内部延伸的问题，公司结合项目持续开展绿色办公、节能宣传周、低碳主题日、员工培训及开放参观等活动，将源网荷储智小屋作为员工绿色教育基地，引导员工参与节能降碳实践。同时结合企业碳管理平台、产品碳足迹、电池护照等数字化建设成果，推动绿色理念向研发设计、生产制造、采购管理及供应链协同延伸，形成从技术创新到企业治理再到产业协同的绿色发展闭环。

Project Outcome

The Eco Smart Home successfully integrates green corporate governance, low-carbon operations, technological innovation, and sustainability communication into a unified demonstration platform.

Equipped with a 108.6 kWp PV system, the building generates approximately 107,000 kWh of renewable electricity annually, achieving a generation-to-consumption ratio of approximately 1.25:1, sufficient to meet its annual operational demand. Supported by a 300 kWh energy storage system, coordinated dispatch across Generation, Grid, Load, Storage, and Intelligence further improves renewable energy utilization. Based on China's national grid emission factors, the project is expected to reduce approximately 94.2 tonnes of CO₂ emissions annually, transforming the building from a conventional energy consumer into an integrated renewable energy producer and consumer.

The project establishes an innovative integrated technical architecture based on Generation, Grid, Load, Storage, and Intelligence, combining hybrid AC/DC distribution, DC building technologies, intelligent energy management, and multi-energy optimization within a real operational environment. The self-developed EMS continuously optimizes PV generation, battery dispatch, and building loads, providing intelligent energy scheduling while supporting future Virtual Power Plant applications and next-generation power systems.

Beyond being a net-zero building, the Eco Smart Home serves as a comprehensive platform showcasing GoodWe's sustainability achievements. Through public tours, customer engagement, technical exchanges, and educational activities, the project effectively integrates sustainability communication, product demonstration, and industry collaboration into a continuous model of exhibition, experience, training, and knowledge sharing. Its successful implementation has already been replicated across additional buildings and customer applications, demonstrating strong scalability and industry-wide applicability.
