Photovoltaic curtain wall as a set of architectural aesthetics and energy production in one of the high-tech products, the installation and construction process of the technology and details of the requirements are very high. This paper elaborates the installation and construction solutions of photovoltaic curtain wall, including construction preparation, construction process, safety and quality control, system commissioning and acceptance criteria.

 

Construction preparation

Before construction, it is necessary to ensure that all design documents are complete, including construction drawings, design instructions, calculations, etc. At the same time, professional training is required for construction personnel to ensure that they are familiar with the characteristics and installation requirements of photovoltaic curtain walls.

Construction process

1. Site setting out and blanking

Technician according to the design drawings in the field of accurate lofting, and prepare the material sheet.

2. Factory processing

According to the blanking list, the manufacturer processes the photovoltaic modules and the required profiles.

3. Material mobilization and hoisting

After the material processing is completed, it will be transported to the construction site and hoisting operation will be carried out.

4. Installation of supporting framework

Install the supporting skeleton of the photovoltaic curtain wall to ensure the stability of the structure.

5. Place the wiring sheath

Install the routing sheath to prepare for subsequent electrical wiring.

6. Install the panel and thread the wire

Photovoltaic panels shall be installed according to the design requirements, and electrical wiring shall be threaded.

7. Glue and check

Complete the sealing glue between the panel and the frame, and do a full inspection.

8. Inverter installation and indoor sealing repair

Install the inverter and complete the sealing and repair of the indoor part.

Safety and Quality Control

Safety is the primary consideration in the construction process. It must be ensured that all construction personnel comply with safe operating procedures and use qualified safety equipment. Quality control involves strict inspection of photovoltaic modules, electrical equipment, connecting lines, etc. to ensure accurate installation, firm connection and good sealing.

System commissioning and operation

After the system is installed, debug and run, including:

1. Grounding and equipotential bonding inspection

Ensure that the earthing system is satisfactory and that the equipotential bonding is correct.

2. Component inspection

Confirm that the PV module is not damaged, the heat dissipation is good, and the wiring is tight.

3. Inspection of electrical equipment

Check whether the inverter, combiner box and other electrical equipment work normally.

4. Test before grid connection

Prior to grid connection, perform necessary electrical tests to ensure that the system meets grid connection requirements.

Acceptance Criteria

The acceptance of photovoltaic curtain wall should follow the following standards:

1. Design Document Compliance

Ensure that the construction results are consistent with the design documents.

2. Installation quality

The installation quality of photovoltaic modules, brackets and electrical equipment is up to standard.

3. System performance

The power generation efficiency and safety performance of the photovoltaic system meet the design requirements.

4. Document Integrity

Construction records, test reports, acceptance documents and other documents are complete.

5. Training and Maintenance

Provide operational training to users and provide detailed maintenance manuals.

Conclusion

The installation and construction of photovoltaic curtain wall is a systematic project, involving design, materials, construction, commissioning and acceptance. Through a professional construction team, strict quality control and comprehensive system testing, the efficient operation and long-term stability of the photovoltaic curtain wall system can be ensured. With the popularity of green building and the concept of sustainable development, photovoltaic curtain wall, as an innovative building integrated solar energy solution, has a broad market prospect and will become an important part of the future construction industry.
