Under the “double carbon” strategy, the construction of green factories and zero carbon parks has become a rigid requirement. In January 2026, the Ministry of Industry and Information Technology and other five departments jointly issued the “Guiding Opinions on Carrying out the Construction of Zero-carbon Plants”, and the new version of the “General Principles for the Evaluation of Green Plants” GB/T 36132-2025 was implemented simultaneously. However, many enterprises are stuck in the same link when applying for green factory certification: insufficient proportion of green electricity and substandard carbon emission data. The root cause is the lack of stable and economical green power supply, which is the scenario that industrial and commercial photovoltaic and rooftop photovoltaic can efficiently solve.
Zhongzheng Energy Technology Development (Shenzhen) Co., Ltd., as the first batch of selected units of the “Zero Carbon Park Creation Service Working Group” of the China Energy Conservation Association, provides enterprises with a clear path of “diagnosis first, investment later, zero cost and fast certification” by virtue of its professional diagnostic capability of “Green Factory Evaluation and Certification Service” and in combination with the original “5 + X” industrial and commercial photovoltaic model. Whether it is a new plant or an existing plant, the deployment of roof photovoltaic can provide enterprises with a continuous and traceable source of green electricity without occupying production space.
“invisible threshold” of green factory: where does green electricity come from?
The new edition of “General Principles for Evaluation of Green Factory” puts forward quantitative requirements on the energy structure and carbon emission intensity of factories. If enterprises want to meet the national green factory standards, they usually need to increase the proportion of green electricity to more than 30%, and complete carbon inventory and emission reduction path verification through third-party organizations. However, self-built photovoltaics often invest millions of yuan, the declaration process is complicated, and there is a lack of professional teams in later operation and maintenance. At the same time, the leasing factory building enterprises are facing a more embarrassing situation: the roof property right of the factory building does not belong to themselves, the lease period is only three to five years, the roof photovoltaic resources are idle for a long time, and the green factory certification is even more impossible. The flexible investment model of industrial and commercial photovoltaics can resolve this contradiction.

Zhongzheng energy won the first batch of “zero carbon park creation service working group member units” of China energy conservation association
Zhongzheng energy plan: do certification diagnosis first, then use the “5 + X” model to make up for the short board of green electricity
the first batch of selected units of the “zero carbon park creation service working group” of China energy conservation association
Zhongzheng energy has deeply ploughed into Guangdong, Hong Kong, Macao and big bay area, and has signed contracts to implement more than 40 distributed photovoltaic projects with a total capacity of over 60 MW, of over 30 MW, the average annual power generation exceeds 30 million degrees and the annual carbon reduction is about 30000 tons. The company strictly selected the global Top5 brand components (Aixu, Longji, Jingao) and inverters (Huawei, Sunshine Power), together with Sumida, Electric Housekeeper Group and other central enterprises, from the source to ensure the quality of power stations. As the first batch of selected units of “zero carbon park creation service working group” of China Energy Conservation Association, the company has won the honors of “national science and technology-based small and medium-sized enterprises” and “excellent enterprise of the year” of Guangdong Solar Energy Association.
Relying on the above actual combat experience and authoritative endorsement, Zhongzheng Energy forms a “certification + energy” closed loop:
The first step is professional evaluation. According to “General Principles for Green Factory Evaluation” and “Zero Carbon Factory Evaluation Code” T/CECA-G 0171-2025, complete energy efficiency diagnosis, carbon inventory and green power gap analysis, and issue customized rectification plan.
The second step is to import the “5 + X” mode.
Zhongzheng Energy fully funded the construction, operation and maintenance of roof photovoltaic, the enterprise zero investment, through the electricity share to enjoy lower than the market price of green electricity. After the first 5-year cooperation period, the enterprise can renew the contract for 3 years to enjoy the ladder electricity price, and the power station will be given free of charge upon expiration. If the contract is not renewed, it will be dismantled free of charge and restored to its original appearance, with zero risk.
The third step, certification declaration.
After the power station is put into operation and the green power data is stably output, Zhongzheng Energy will assist in sorting out the emission reduction certificates, complete the third-party evaluation and government audit, and help the enterprise to win the green factory certification and the highest one-time reward of 500000 yuan.

Shajing over the rainbow case verification: photovoltaic power generation paves the way for certification
Shenzhen shajing over the rainbow shopping mall has adopted the” 5 + X “model to build 1.2 MW roof photovoltaic, generating 1.4 million degrees of electricity per year and reducing more than 1500 tons of carbon. it has been successfully selected into Shenzhen’s near-zero carbon emission pilot project, saving more than one million yuan in electricity charges per year. This is exactly the “preview” of green factory certification “.

From Certification to Power Generation, zhongzheng Energy wants to be the” zero carbon partner “of the enterprise
For enterprises that do not meet the declaration conditions of green factories, Zhongzheng Energy also provides” pre-diagnosis “service: first, it helps enterprises install industrial and commercial photovoltaic at low cost through the” 5 + X “mode, and then starts the certification process after accumulating 1-2 years of real emission reduction data. This two-way empowerment of “promoting certification by power generation and leading power generation by certification” has completely broken the deadlock that enterprises “dare not report if they want to report, but fail to pass.
In the future, Zhongzheng Energy will continue to deepen its efforts in the Guangdong-Hong Kong-Macao Greater Bay Area, with green factory evaluation and certification services as its entrance and the “5 + X” industrial and commercial photovoltaic model as its engine, so that every manufacturing enterprise, every logistics park and every commercial complex can have green power with zero threshold and pass authoritative certification with zero anxiety. From energy investments to zero carbon certification, Zhongzheng Energy is your most trusted full-cycle partner.
