Shenzhen High-tech Primary School's BIPV project generates over 300,000 kWh annually with its 'five-sided photovoltaic' system

 

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

 

Located in Yuehai Street, Nanshan District, Shenzhen, Shenzhen High-tech Primary School is scheduled to officially open in September 2025. It is a key livelihood project of Nanshan District and notably, the first near-zero energy consumption school in South China.

 

 

This livelihood project, planned by the Nanshan District Architectural Engineering Office and with EPC general contracting by China Construction Science and Technology Group, not only sets a new low-carbon record for Shenzhen's educational buildings but also transforms the campus into an 'electricity-generating ecological classroom' through its innovative 'five-sided photovoltaic' design, generating over 300,000 kWh annually and reducing carbon emissions by over 140tCO2 ₂ , equivalent to afforestation of 150,000 square meters.

 

Shenzhen High-tech Primary School boasts a unique architectural style, characterized by its light, smooth, simple, and elegant design, with a rational and comprehensive functional layout. Within the campus, courtyard spaces and urban greenery interpenetrate and integrate, creating a unique atmosphere that is technologically advanced, open, inclusive, and ecologically vibrant, fully showcasing the unique characteristics of a Bay Area campus. The teaching building serves as a prime example of the successful application of photovoltaics in the field of architecture, with photovoltaic components cleverly utilized on the roof, railings, and sunshades, adding a unique touch of green technology to the campus.

 

 

Hongke Green Energy, leveraging its core technological strength and extensive BIPV experience, has infused green energy into this educational livelihood project, contributing to Shenzhen's low-carbon city construction.

 

01


The perfect fusion of technology and nature

 

Near-zero energy consumption design

 

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

 

 

Five-sided photovoltaic system

High-efficiency power generation area on the roof: Utilizing 358 pieces of 635Wp monocrystalline silicon components + 282 pieces of 125Wp cadmium telluride components, the 2% roof drainage slope precisely optimizes light energy capture.

 

To balance the dual needs of daylighting and power generation efficiency, an innovative approach combining crystalline silicon photovoltaic components and thin-film photovoltaic components was adopted. Crystalline silicon components, with their high power generation performance, are scientifically and rationally laid out to fully capture sunlight and convert it into a continuous supply of electricity; while thin-film components, with their excellent light transmission properties, meet the indoor lighting needs while generating electricity. The two complement each other, providing the teaching building with stable and sufficient power support.

 

 

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

East and West railings: Deployment of 24 pieces of 170Wp cadmium telluride components, whose light transmission characteristics serve both 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 of the building surface.

Material Selection Wisdom

A mix of monocrystalline silicon (high efficiency) and cadmium telluride (strong weak light performance) components, balancing power generation efficiency and architectural aesthetics, improving shadow loss resistance by 30%.

 

 

Energy storage and flexible power consumption

Total installed capacity of 328KW, equipped with a 300kWh lithium iron phosphate energy storage device, a low-voltage DC power distribution system, and DC air conditioners, DC sockets, and DC lights, realizing flexible power consumption in the building.

Hongke Green Energy's "Photovoltaic Storage Direct Flexible" full-chain service practice

 

 

Intelligent operation and maintenance system

Integrating "photovoltaic storage direct flexible" technology, dynamically regulating photovoltaic power generation and power consumption load to ensure stable energy supply to the campus and responding to Shenzhen's BIPV policy requirements.

 

Full-cycle service guarantee

From equipment supply to construction and installation, Hongke Green Energy participated in the entire project implementation, relying on the EPC general contracting model for efficient collaboration, solving the cross-professional integration problems of BIPV, and ensuring seamless integration of the photovoltaic system and building structure.

The "Shenzhen Model" of green buildings

 

Transforming from "energy consumer" to "energy producer", every photovoltaic panel in High-tech Primary School is writing the future of green education. It is not only a hall of knowledge but also a vibrant laboratory for a city's progress towards carbon neutrality.

 

 

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

 

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