Why Bunney’s Inc.
-
Desert-proven methods: Built for high UV index, thermal cycling, and monsoon dust.
-
Right-fit materials: UV-stabilized polymers, fluoropolymer/PU topcoats, and corrosion-resistant fasteners.
-
Low-disruption work: Planned around operations with clear QA/inspection reports.
-
End-to-end support: Audit → specification → installation → monitoring.
What is “solar erosion”?
Sun, heat, and airborne grit gradually degrade exposed materials. The result: chalking paints, embrittled plastics, crazed sealants, faded finishes, softened cable jackets, and accelerated corrosion—especially on assets that live outdoors year-round.
Typical impacts
-
Reduced solar output from soiling, micro-cracks, or weathered coatings
-
Premature failures of backsheets, junction boxes, gaskets, and cable insulation
-
Loose or corroded hardware from thermal expansion and galvanic mismatch
-
Aesthetic and safety issues on buildings, fences, and traffic assets
Assets we protect
-
PV arrays: Modules, racking, wire management, combiner boxes, and foundations
-
Facilities & sites: Roofing, façades, doors, handrail, bollards, and perimeter fencing
-
Civil works: Equipment pads, barriers, signage, and exposed concrete/steel
How we combat UV/heat degradation
-
Material upgrades: UV-stabilized polymers, 316 stainless or HDG + isolation washers, FRP components where appropriate
-
Protective coatings: High-build epoxies, polyurethane or PVDF topcoats, elastomeric sealants rated for thermal movement
-
Dust & soiling control: Wash plans, anti-soiling coatings, stabilized access roads, and wind fencing where permissible
-
Design detailing: Shading/vent gaps, drip edges, proper cable bend radius, and hardware torque specs for thermal cycling
-
Monitoring & testing: IR thermography, torque checks, coating DFT readings, and photo-logged inspections
Our process
-
Site assessment: Condition grading, UV/heat exposure mapping, and risk ranking
-
Specification: Product-agnostic recommendations matched to service environment
-
Execute: Surface prep, coating/retrofit, wire-management cleanup, and hardware upgrades
-
Validate: Adhesion/DFT tests, torque logs, and punch-list closeout
-
Maintain: Seasonal inspection and wash schedule with ROI tracking
Benefits
-
Higher, steadier energy production
-
Fewer field failures and truck rolls
-
Longer asset life and cleaner audits
-
Better curb appeal for public-facing facilities
The Role of Technology in Combating Solar Erosion
Advancements in materials science and engineering are improving resistance to solar erosion. Some notable innovations include:
- Nano-Coatings: Ultra-thin layers that enhance UV resistance and protect surfaces from degradation.
- Self-Healing Materials: These materials can repair minor damage caused by UV exposure, reducing the need for frequent maintenance.
- AI Monitoring Systems: Artificial intelligence is being used to monitor solar installations for signs of erosion, enabling proactive maintenance.
- Enhanced Solar Panel Design: Modern panels incorporate UV-resistant materials and improved coatings to withstand harsh conditions.
FAQs
What’s the biggest driver of material breakdown here?
A mix of high UV exposure, large day-night temperature swings, and abrasive dust acting like sandpaper over time.
Can coatings really extend panel performance?
We don’t coat active cell glass, but anti-soiling/topcoat systems on frames, racking, and balance-of-system parts reduce corrosion and soiling that indirectly hurts output.
How often should arrays be washed?
It’s site-specific. Many desert sites benefit from quarterly cycles, increased after dust storms or nearby earthwork.
Do you work on live sites?
Yes. We stage work around production, follow lockout/tagout where required, and keep strings online whenever safe and practical.
What documentation do we receive?
A concise report with photos, test results (DFT/adhesion/torque), materials used, warranties, and a maintenance plan.
