Manufacturing Process

1. Absorber sheet fabrication: welding copper tubes to coated plate

2. Glass and frame assembly: sealing with high-temperature adhesive

3. Insulation foaming to minimize thermal losses

4. Hydrostatic and pressure leakage test

5. Surface corrosion resistance treatment

6. System assembly and thermal performance testing

7. Export-grade packaging to withstand long-distance transportation

Industry Comparison Table

Application Scenarios

• Hotels, hospitals, dormitories

• Residential villas and apartments

• Industrial hot water processes ≤95°C

• Swimming pools and sports centers

• Government / EPC energy conservation projects

Core Pain Points & Engineering Solutions

• Limited roof space → Higher efficiency per area than tube collectors

• Uneven solar resource → Modular design allows scalable system configuration

• Corrosion & water quality issues → Closed-loop heat exchange protection

• High heat loss in old buildings → PU insulation and optimized pipe routing

• Wind and seismic challenges → Certified structural mounting system

Risk Warning & Mitigation Advice

• Poor sealing → Water leakage → Ensure certified testing reports

• Improper bracket installation → Safety risk → Follow engineering standards

• Insufficient freeze protection → Pipe cracking → Use glycol antifreeze loop

• Oversizing → Waste investment → Follow actual flow demand calculation

Procurement Selection Guide

1. Confirm daily hot water consumption

2. Evaluate local solar radiation level

3. Select forced circulation for multi-floor buildings

4. Check absorber coating type and efficiency test data

5. Review installation structural drawings and accessories

6. Verify certifications: ISO, CE, Solar Keymark

7. Assess supplier engineering support and after-sales service
