PV Combiner Boxes in Harsh Environments: Design and Deployment Tips
Environmental Challenges
- High heat → faster degradation
- Salt air → corrosion risks
- Dust and sand → ventilation issues
Design Solutions
Use stainless steel or polycarbonate enclosures with pressure relief valves and coated internals.
Real Case Example
A Middle East solar plant used custom sand-proof combiner boxes with no failures after 5 years of operation at 50°C+ temperatures.
Conclusion
With proper material choice and layout, your combiner box can survive and perform even in extreme conditions.
