Project Case 丨 "Five-Sided Photovoltaic" Annual Power Generation Exceeds 300,000 kWh: Shenzhen High-tech Primary School BIPV Project

 

In July 2025, Shenzhen High-tech Primary School's Building Integrated Photovoltaic (BIPV) project officially passed the completion acceptance.

 

Shenzhen High-tech Primary School is located in Yuehai Street, Nanshan District, Shenzhen, and is scheduled to officially open in September 2025. It is a key livelihood project built by Nanshan District. It is worth mentioning that it is also the first new school in South China with the design concept of "near-zero energy consumption".

 

 

This livelihood project, which is planned and constructed by the Nanshan District Construction Works Department and EPC general contracted by China Construction Science and Industry Group, not only broke the low-carbon record of Shenzhen's educational buildings, but also used the innovative design of "five-sided photovoltaic" to transform the campus into a "power-generating ecological classroom" with an annual power generation of over 300,000 kWh and a carbon reduction of over 140tCO ₂ , equivalent to planting 150,000 square meters of trees.

 

The architectural style of Shenzhen High-tech Primary School is unique, with an overall light and smooth, simple and generous design, and a reasonable and complete functional layout. Inside the campus, the courtyard space and urban greening penetrate and integrate with each other, creating a unique atmosphere full of technology, openness, inclusiveness, and ecological atmosphere, fully demonstrating the unique campus characteristics of the Bay Area. The teaching building has become a model of successful application of photovoltaics in the field of construction. Photovoltaic modules are cleverly used in different areas such as roofs, railings, and sunshades, adding a unique green technological color to the campus.

 

 

With its core technological strength and rich BIPV experience, Hongke Green Energy has injected green energy into this educational livelihood project, helping Shenzhen build a low-carbon city.

 

01


The perfect integration of technology and nature

 

"Near-zero energy consumption" design

 

The project integrates high-performance envelope structure, efficient equipment, and BIPV technology, with a comprehensive energy saving rate of 84.32%, reaching the near-zero energy consumption standard. The photovoltaic system simultaneously realizes power generation and building energy saving optimization, providing a systematic solution for low-carbon transformation of public institutions.

 

 

Five-sided photovoltaic system

High-efficiency power generation area on the roof: 358 pieces of 635Wp monocrystalline silicon components + 282 pieces of 125Wp cadmium telluride components are used, and the 2% drainage slope of the roof is accurately optimized for light energy capture.

 

In order to balance the dual needs of lighting and power generation efficiency, an innovative method of combining crystalline silicon photovoltaic modules and thin-film photovoltaic modules is adopted. With its efficient power generation performance, crystalline silicon modules can fully capture sunlight and convert it into a continuous source of electricity through scientific and reasonable laying; while thin-film modules, with their good light transmittance, meet the needs of indoor lighting while generating electricity. The two complement each other and jointly provide stable and sufficient power support for the teaching building.

 

 

East, west, south and north facades: 228 pieces of 270Wp monocrystalline silicon components are deployed.

East and west railings: 24 pieces of 170Wp cadmium telluride components are deployed, and their light transmission characteristics take into account the dual functions of shading and power generation.

 

 

A hybrid energy matrix of "monocrystalline silicon high-efficiency power generation + cadmium telluride weak light supplement" is formed to achieve all-year energy coverage on the building surface.

Wisdom in material selection

Hybrid monocrystalline silicon (high efficiency) and cadmium telluride (strong weak light performance) components take into account power generation efficiency and architectural aesthetics, and the anti-shadow loss capacity is increased by 30%.

 

 

Energy storage and flexible power consumption

With a total installed capacity of 328KW, it is equipped with a 300kWh lithium iron phosphate energy storage device, a low-voltage DC power distribution system, and DC air conditioners, DC sockets, DC lights and other power equipment to achieve flexible building power consumption.

Hongke Green Energy's "PV Storage Direct Flex" full-chain service practice

 

 

Intelligent operation and maintenance system

Integrate "PV Storage Direct Flex" technology to dynamically regulate photovoltaic power generation and electricity load to ensure stable energy supply to the campus and respond to Shenzhen's BIPV policy requirements.

 

Full cycle service guarantee

From equipment supply to construction and installation, Hongke Green Energy participates in the project implementation throughout the entire process, relying on the EPC general contracting model to efficiently coordinate and solve the problem of BIPV cross-professional integration, ensuring seamless connection between the photovoltaic system and the building structure.

 

03


The "Shenzhen Model" of green building

 

From "energy consumer" to "energy producer", every photovoltaic panel in Gaoxin Primary School is writing the future of green education. This is not only a hall of knowledge, but also a vivid laboratory for a city to move towards carbon neutrality.

 

 

The dance of sunshine, greenery and technology makes Gaoxin Primary School a vivid classroom for green education. Here, every photovoltaic panel is a footnote to ecological civilization, and every kilowatt-hour of electricity is the hope of the future.

 

In September 2025, this "power-generating campus" will welcome its first students, and its story has just begun.
