Project Case | "Five-sided Photovoltaics" Annual Power Generation Exceeds 300,000 kWh: Shenzhen High-tech Primary School BIPV Project

In July 2025, the Shenzhen High-tech Primary School Building-integrated Photovoltaics (BIPV) project officially passed the completion acceptance.

 

Shenzhen High-tech Primary School is located in Yuehai Subdistrict, Nanshan District, Shenzhen. It is planned to officially open in September 2025 and is a key livelihood project in Nanshan District. Notably, it is also the first new-type school in South China designed with a "near-zero energy consumption" concept.

 

 

This livelihood project, coordinated by the Nanshan District Construction and Public Works Bureau and EPC contracted by China State Construction Engineering Corporation, not only sets a new low-carbon record for educational buildings in Shenzhen but also, with its innovative "five-sided photovoltaic" design, transforms the campus into an "eco-classroom that generates electricity," producing over 300,000 kWh annually and reducing carbon emissions by more than 140 tons of CO2. ₂ Equivalent to afforestation of 150,000 square meters.

 

The architectural style of Shenzhen High-tech Primary School is uniquely crafted, with an overall light, smooth, and simple yet elegant design, reasonable and comprehensive functional layout. Inside the campus, courtyard spaces and urban greenery interpenetrate and interact, creating a unique atmosphere full of technology, openness, inclusiveness, and ecological vitality, fully highlighting the distinctive campus characteristics of the Bay Area. The teaching building has become a model for the successful application of photovoltaics in architecture, with photovoltaic modules cleverly applied on roofs, railings, sunshades, and other areas, adding a unique touch of green technology to the campus.

 

 

Hongke Green Energy, leveraging its core technological strength and rich BIPV experience, injects green momentum into this educational livelihood project, supporting Shenzhen's low-carbon city construction.

 

01


The perfect integration of technology and nature.

 

"Near-zero energy consumption" design.

 

The project integrates high-performance envelope structures, efficient equipment, and BIPV technology, achieving a comprehensive energy-saving rate of 84.32%, meeting near-zero energy consumption standards. The photovoltaic system simultaneously optimizes power generation and building energy savings, providing systematic solutions for low-carbon transformation of public institutions.

 

 

Five-sided photovoltaic system.

High-efficiency rooftop power generation area: Using 358 pieces of 635Wp monocrystalline silicon modules and 282 pieces of 125Wp cadmium telluride modules, the roof has a 2% drainage slope precisely optimized for solar energy capture.

 

To balance lighting and power generation efficiency, an innovative combination of crystalline silicon photovoltaic modules and thin-film photovoltaic modules is adopted. The crystalline silicon modules, with their high power generation efficiency, are scientifically and reasonably laid out to fully capture sunlight and convert it into continuous electricity; the thin-film modules, with good light transmittance, meet indoor lighting needs while generating power. The two complement each other, jointly providing stable and sufficient power support for the teaching building.

 

 

East, West, South, and North facades: Deployed 228 pieces of 270Wp monocrystalline silicon modules.

East and West railings: Deployed 24 pieces of 170Wp cadmium telluride modules, whose light transmittance balances shading and power generation functions.

 

 

Forming a hybrid energy matrix of "high-efficiency monocrystalline silicon power generation + cadmium telluride weak light supplementation," achieving year-round energy coverage on building surfaces.

Smart material selection.

Mixing monocrystalline silicon (high efficiency) and cadmium telluride (strong weak-light performance) modules to balance power generation efficiency and architectural aesthetics, improving shadow loss resistance by 30%.

 

 

Energy storage and flexible electricity use.

Total installed capacity of 328KW, equipped with a 300kWh lithium iron phosphate energy storage system, building a low-voltage DC distribution system, equipped with DC air conditioners, DC sockets, DC lights, and other electrical devices to achieve flexible electricity use in the building.

02


Hongke Green Energy's full-chain "PV-Storage-DC-Flexible" service practice.

 

 

Intelligent operation and maintenance system.

Integrating "PV-Storage-DC-Flexible" technology to dynamically regulate photovoltaic power generation and electricity load, ensuring stable energy supply for the campus and responding to Shenzhen's BIPV policy requirements.

 

Full-cycle service guarantee.

From equipment supply to construction and installation, Hongke Green Energy participates throughout the project implementation, relying on the EPC general contracting model for efficient collaboration, solving BIPV cross-disciplinary integration challenges, and ensuring seamless connection between photovoltaic systems and building structures.

 

03


The "Shenzhen Model" of green buildings.

 

From an "energy consumer" to an "energy producer," every photovoltaic panel at High-tech Primary School is writing the future of green education. This is not only a temple of knowledge but also a living laboratory for the city’s journey toward carbon neutrality.

 

 

The dance of sunlight, greenery, and technology makes High-tech Primary School a vibrant classroom of green education. Here, every photovoltaic panel is a footnote of ecological civilization, and every kilowatt-hour is a hope for the future.

 

In September 2025, this "electricity-generating campus" will welcome its first students, and its story is just beginning.
