Who is the “invisible escort” behind the PV lab? - Datang Project Chronicle

Background

In July 2024, Zealwe Technology undertook the project of installing photovoltaic test equipment in Datang Laboratory. As the core construction content of the laboratory, the project covers the whole process of 20 items of equipment delivery, installation, commissioning, metrology and training services, with the aim of providing high-precision testing support for scientific research in the field of new energy.

The project started on July 16 and all orders were delivered on December 4, a time span of 4.5 months, according to the contract. Actual construction period 1 month

Delivery results:  

1. Efficient fulfillment: 100% on-time delivery of 20 sets of precision equipment 

2. Precise implementation: all equipment intermodulation tests meet the standard at one time 

3. Compliance delivery: all equipment passes the metrological certification, and all kinds of technical documents are delivered in full 

Four major challenges and professional responses

Challenge 1: equipment into the field shifting difficulties 

 Problem: the customer laboratory floor has been paved with floor leather, and part of the equipment volume, weight is huge, can not use the traditional lifting, pushing and pulling and other handling solutions, at the same time, pay attention to, to meet the laboratory precision level layout positioning 

Solution: 

using the bottom seamless steel tube rolling pan, the technical team to monitor the whole process. Segmented lifting strategy to avoid equipment damage and laboratory facilities to protect the integrity of the collision. Ground protection layer without indentation residue.

Challenge 2: Tight Installation Manpower 

Problem: Shortage of skilled workers during peak construction periods affects progress. 

Solution: Optimized the construction process by adopting a “modular division of labor” model, staggered operations, and a significant increase in installation efficiency.

Challenge 3: Delay in the peripheral progress of water, electricity and gas 

Problem: The lagging of supporting works led to the obstruction of the commissioning program. 

Solution: 

1, set up a special coordination team, and water, electricity and gas suppliers actively detailed docking, pipeline installation process and flow rate ratio calculation, to provide process diagrams and pipeline installation requirements and equipment the rest of the peripheral needs; daily docking site engineering to ensure that the project can be efficiently advanced according to the plan.

2、Prioritize the completion of independent commissioning of key equipment to reduce the impact of overall delays.

Challenge 4: Insufficient testing time 

Problem: Some equipment performance tests have not reached the expected duration. 

Solution: 

1. Extend the debugging cycle, and after communicating with the customer, increase the night test function verification; 

2. Introduce a remote monitoring system to analyze the equipment operation data in real time to ensure the integrity of the test.

Service value and customer recognition 

1. Scientific research capacity enhancement: after the equipment is put into operation, the laboratory testing accuracy reaches the industry standard. Support the multi-dimensional testing needs of PV modules.

2. Long-term service guarantee: provide 3-month free operation and maintenance support, establish equipment operation files, and commit to 24-hour response mechanism.

3. Customer evaluation: The person in charge of Datang Laboratory said: the whole process of the project is efficient, technically in place and responsive; the documents are complete, detailed and easy to use and access. Overall satisfaction!

The practice of Zealwe Tech service concept 

1. professional-oriented: strict compliance with IEC61215, IEC61730 and other international standards, to ensure that the equipment installation and commissioning compliance; 

2. good faith performance: strict adherence to the terms of the contract, the key nodes in advance to confirm with the customer, to avoid the difference in information; 

3. the service is paramount: the project is delivered to continue to follow up after the completion of the operation of the laboratory personnel to assist in completing the training.

Conclusion: 

The successful implementation of the Datang project confirms Zealwe Tech's comprehensive service capability in the field of new energy testing. In the future, we will continue to provide customized solutions to our global customers with “Precision, Reliability and Efficiency” as our guideline, and help new energy industry technology innovation.

From the author, Li Zhibin: 

Since joining Zealwe Tech in May 2022, I have gradually grown from an after-sales assistant to an after-sales engineer. In the past three years, I have been actively involved in the construction and implementation of many important projects, including the National Quality Supervision and Inspection Center for Photovoltaic Equipment (Luoyang Quality Inspection Institute), Datang Laboratory, TTL Lab in Jiaxing, Jianhu Runda Laboratory, and European customers, etc. These experiences have not only improved my teamwork, communication and technical support skills, but also enabled me to work closely with our customers.

These experiences have not only enhanced my project management skills, but also allowed me to accumulate rich experience in teamwork, customer communication and technical support. In the future, I will continue to maintain a high level of professionalism and consistently provide quality services to our customers.
