Strategic Advancement of Key Photovoltaic Projects by the Survey and Design Institute

Focused Development: The Survey and Design Institute Accelerates Key Photovoltaic New Energy Projects

Date: 2025-09-22

In response to the urgent need for transformation and upgrades within the industry, the Survey and Design Institute has consistently adhered to an innovation-driven development philosophy. This approach aims to enhance core competitiveness and strengthen essential functions while actively engaging in the exploration and construction of strategic emerging industries such as photovoltaic (PV) new energy. Through scientific planning, precise construction, and comprehensive management, the institute has made significant strides in various areas including rooftop distributed photovoltaic systems and large-scale ground-mounted power stations, leading to notable progress in multiple projects.

The Guangning County Public Rooftop Distributed Photovoltaic Project (Phase I) serves as a key demonstration project for distributed photovoltaic power generation in Guangning County. The Design Institute guarantees efficient power generation and safe operation through its professional capabilities, assisting Guangning in establishing a benchmark for green energy and promoting energy transformation and sustainable development within the county. Since its launch, the project has had profound implications across several dimensions, including energy supply, industrial upgrading, ecological protection, urban image enhancement, and improvements in social welfare.

This project effectively utilizes the rooftops of government public buildings, employing an innovative dual-mode system of “sunshade + array support.” It has constructed a green energy power station with a total installed capacity of approximately 6.6 MWp across various locations, including Phase II of the High-tech Industrial Park, the Maternal and Child Health Hospital, the Sports Training Center, and the County Traditional Chinese Medicine Hospital. Operating under a “self-consumption + surplus grid connection” mechanism, the solar power station utilizes public rooftops. Currently, installations have been completed in Phase II of the High-tech Industrial Park, with 315.06 kWp installed in Area A2 and 784.11 kWp in Area A7, awaiting grid connection. This model provides a replicable “Guangning Sample” for the green transformation of industrial parks in the county, creating a synergistic effect of “photovoltaics + buildings” to assist in achieving carbon peak and carbon neutrality goals.

The Korqin Left Wing Banner 35.91 MW Photovoltaic Assistance Power Station is a comprehensive project that integrates clean energy development, ecological protection, and rural revitalization, precisely aiding 3,591 people. The Design Institute has conducted precise quantitative design and scientific planning for the layout of photovoltaic installations in Korqin, ensuring efficient power generation and laying a solid foundation for the project’s successful advancement, making it a green engine for ecological governance and rural revitalization in the Tongliao region. Located in the Korqin Left Wing Banner of Tongliao City, Inner Mongolia, the project has a total installed capacity of 37.35 MW, with a rated capacity of 35.91 MW on the AC side. By utilizing 615Wp and 620Wp bifacial modules along with string inverter technology, it operates under a multi-dimensional development model of “on-panel power generation, below-panel sand control, and industry benefits for the people.” The project is constructed in two plots, and the first-year power generation is expected to reach 52.86 million kWh upon completion. The Design Institute will continue to support the advancement of remaining construction work for the Korqin photovoltaic assistance project to ensure full-capacity grid connection and power generation at the earliest opportunity.

The Xianyang City Wugong County Henglian Zhongyi and Meinong Technology 5.94 MW Commercial Rooftop Distributed Photovoltaic Power Generation Project marks the first distributed photovoltaic EPC project obtained through independent marketing by Shaanxi Jianghe Water Conservancy Hydropower Civil Survey and Design Co., Ltd. This project is significant for promoting the local industry’s green and low-carbon transformation and establishing a sustainable development ecosystem. The project is located within the sites of Shaanxi Henglian Zhongyi Industrial Co., Ltd. and Shaanxi Meinong Network Technology Co., Ltd., effectively utilizing a total rooftop area of approximately 56,695 square meters to construct a system with a total capacity of 5.94 MW (installed capacity of 7.127 MWp). It employs N-type 580Wp monocrystalline mono-glass solar modules, using fixed brackets for a flat layout. The orientation of the modules is adjusted according to the buildings, with each string comprising 24 modules. It operates under a “self-consumption, surplus electricity grid connection” model, and calculations indicate that the theoretical power generation in the first year will be 7,181 MWh, with an annual utilization of 1,008 hours. Over a 25-year operating period, the total grid-connected electricity generation is expected to reach 167,378 MWh, with an average annual grid-connected electricity generation of 6,695 MWh and an average annual utilization of 939 hours. The project has now been completed, effectively easing the local power supply pressure and injecting green momentum into regional development.

In the journey of developing the new energy industry, the Design Institute actively responds to national strategic calls, closely following major company decisions and contributing to photovoltaic new energy projects. From deeply participating in the Jia Yu Guan 770 MW Large-Scale Photovoltaic Power Generation Project to independently handling various small and medium-sized photovoltaic EPC projects such as the “High-Efficiency Photovoltaic Array” at the Wugong plant, the “Photovoltaic Blue Sea” in the Korqin sandy area, and the “Sunshine Matrix” on the rooftops of Guangning, the Design Institute consistently upholds its professional spirit. By taking practical actions, it promotes the efficient construction of photovoltaic new energy projects, demonstrating significant strength and comprehensive planning capabilities in both the small and medium-sized photovoltaic EPC sector and large-scale project surveying and design. Moving forward, the Design Institute will continue to delve into new strategic fields, relying on high-quality projects to overcome technical bottlenecks, optimize service chains, proactively serve the market, and continuously shape new momentum and advantages for development, thereby making a solid contribution to the high-quality advancement of new energy for both the company and the industry.
