The distribution network welcomes a "new role": the distributed energy revolution driven by BIPV technology

Distribution network revolution: BIPV technology reconstructs the energy infrastructure ecosystem

Chapter 1 Policy Windfall: Top-level Design of New Power System Construction

1.1 Analysis of National Strategic Framework

The release of the National Development and Reform Commission's "Guiding Opinions on the High-Quality Development of Distribution Networks under the New Situation" in 2024 marks the entry of China's distribution network construction into the 3.0 era. The document clearly proposes the core goals of "two transformations":

• Transformation of form: from a unidirectional radiation network to a multidirectional interactive network

• Transformation of function: upgrading from a distribution service provider to a resource allocation platform

In this context, the Ministry of Housing and Urban-Rural Development simultaneously released the "Guidelines for the Construction of Building Photovoltaic Systems", emphasizing: "By 2027, the installation rate of BIPV in new industrial buildings should not be less than 60%, and the installation rate of retrofitted existing buildings should not be less than 30%." The policy combination has opened up a market space worth hundreds of billions for photovoltaic metal roofing technology.

1.2 Local Practice Sample: Zhejiang Model Innovation

As the first provincial-level demonstration zone for the new power system in the country, Zhejiang Province issued the "Guidelines for the Construction of Smart Distribution Networks" in 2024, innovatively proposing a "three-integration" development path:

• Building energy transformation: transforming buildings into energy production units

• Intelligent distribution network: building a millisecond response digital twin system

• Market-oriented trading: establishing a distributed resource aggregation trading mechanism

Data shows that Zhejiang has formed three major industrial clusters through policy guidance:

1. Hangzhou Qiantang New District BIPV Intelligent Manufacturing Base (annual production capacity of 5GW)

2. Ningbo Photovoltaic Metal Materials R&D Center (143 patented technologies)

3. Wenzhou Distributed Energy Trading Platform (annual trading volume exceeding 2 billion kWh)

Chapter 2 Technological Breakthrough: Five Innovative Dimensions of BIPV Solutions

2.1 Structural Innovation: Deep Integration of Architecture and Photovoltaics

The "three high pain points" (high load, high leakage, high maintenance) existing in traditional distributed photovoltaics are being solved by the new generation of metal roofing BIPV technology:

• Load revolution: using aerospace aluminum-magnesium alloy frames to achieve an ultra-light structure of 7.8kg/㎡ (60% lighter than traditional solutions)

• Waterproof breakthrough: a four-fold sealing system passed the ASTM E331 heavy rain test, ensuring zero leakage for 25 years

• Operation and maintenance upgrade: intelligent cleaning robot systems reduce the power generation efficiency decay rate to 0.3%/year

Typical case: a 120,000㎡ roof renovation project for an automobile manufacturing plant

• Using XX company's third-generation BIPV system

• Installed capacity of 15MW, annual power generation of 18 million kWh

• Construction period of only 45 days (60% shorter than traditional solutions)

Midday flat period	100%	0%	50%	50%
Evening peak	5%	70%	25%	0%

2.5 Management Innovation: Digital Twin Operation and Maintenance System

Build a "three-dimensional visualization management platform" to achieve:

• Component-level monitoring (accuracy ±1%)

• Automatic diagnosis of hot spots (accuracy rate 99.2%)

• Dust loss prediction (error <3%)

• Automatic drone inspection (efficiency increased by 20 times)
