Solar Erosion in Arizona

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

1. Site assessment: Condition grading, UV/heat exposure mapping, and risk ranking

2. Specification: Product-agnostic recommendations matched to service environment

3. Execute: Surface prep, coating/retrofit, wire-management cleanup, and hardware upgrades

4. Validate: Adhesion/DFT tests, torque logs, and punch-list closeout

5. 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.
