Changsha Huanghua Airport Comprehensive Bonded Park 3.76MW Distributed Photovoltaic Project Case

I. Project Overview

Changsha Huanghua Airport Comprehensive Bonded Park Distributed Photovoltaic Project is the first logistics park PV demonstration project with integrated supply chain in Hunan Province, with a total installed capacity of 3.76MWp, 13,420 pieces of high-efficiency monocrystalline silicon photovoltaic modules, and an average annual power generation capacity of 3,511,300 kWh. Relying on the concrete sloped roof resources of the bonded park, the project achieves a 15% reduction in kWh cost through the configuration of first-line brand products and supply chain synergy optimization, providing an innovative sample for the green transformation of the logistics industry.

Ⅱ.Technical Solutions and Core Advantages

1. Customized design adapted to concrete sloped roofs

In view of the structural characteristics of the sloping concrete roof in the park, the project evaluates and decides to adopt a lightweight bracket system and non-slip fixing technology to ensure that the roof load safety and wind resistance meet the standards.

The layout of PV modules optimizes the matching of slope and orientation to reduce shadow shading and increase the power generation efficiency per unit area to 18.8%.

2. Full chain integration of first-tier brands

LONGi Hi-MO 5 series 550Wp high-efficiency modules, the PV conversion rate of 21.3%, in addition to the use of Huawei intelligent inverters and sunlight power distribution system, to ensure that the power station 25 years of stable operation of the whole life cycle.

It also integrates an AI monitoring platform to realize power generation prediction, fault diagnosis and remote operation and maintenance, with a system availability rate of over 99.5%.

3. Supply Chain Collaboration for Cost Reduction

Through centralized procurement and strategic cooperation, the company locks the price of equipment, shortens the logistics cycle by 30%, and reduces the comprehensive cost of EPC to RMB 3.8/Wp.

Ⅲ.Economic Benefits and Environmental Value

1. Energy Benefits

The average annual power generation of this bonded park project is 3,511,300 kWh, and the self-reliance ratio of the park reaches 85%, which saves more than 2.45 million yuan in electricity costs annually.

The total power generation capacity is estimated to be 87.78 million kWh during the 25-year operation period, which is equivalent to a reduction of 85,000 tons of CO₂ emissions.

2. Industrial Synergy

The PV power supply in the bonded park prioritizes the supply of high-energy-consuming links such as cold chain warehousing and intelligent sorting in the bonded zone, which reduces the energy cost of logistics enterprises by 12%. The project and the airport PV parking shed form a regional energy complementary network to enhance the green power consumption capacity of the area.

Ⅳ.Industry Promotion Value

1. Standardized model output

The bonded park PV project has formed the “Logistics Park Concrete Roof PV Technical Guidelines”, which provides standardized solutions for similar scenarios, such as component selection and load accounting.

2. Demonstration of government-enterprise cooperation

Combined with Hunan Province's “New Energy Unified Market” policy, the project explores the tax incentives and green power trading mechanism of “Free Trade Zone + New Energy”.

Through brand integration, supply chain optimization and scenario adaptation, the airport comprehensive bonded park PV project achieves a balance of “high yield-low cost-low risk” for the logistics park PV project, and provides replicable experience for energy upgrading of bonded zones nationwide.
