Reflective urban / dry ground

Require radiation-shield evidence, ventilation strategy, surface metadata, and field validation against aspirated references.

Cold snow and ice

Require heater-state reporting, snow/ice recovery behavior, albedo sensitivity evidence, and winter service access.

Hot humid / tropical rain

Require wetting recovery, corrosion resistance, high-rain QA, biofouling control, and condensation management.

Coastal salt

Require corrosion materials, connector sealing, lightning/surge protection, and maintenance procedures.

Arid dust

Require dust ingress protection, shield cleanability, solar-sensor fouling plans, and power derating for dirty panels.
