North Carolina pollen does not stay on your car. It stays on your panels too.
Why Raleigh-area panels get dirty fast
The Triangle gets long pollen seasons, humid summers, dust from growing suburbs, and enough tree canopy to keep rooftop glass under constant pressure. That means even clean-looking arrays can lose clarity.
When pollen and grime combine, rain often spreads the problem instead of removing it.
Why the math still matters
If a dirty array drops production by even a modest amount, the loss adds up across the season. On some systems, a badly neglected surface can approach a 25% efficiency hit.
Cleaning is not about chasing perfection. It is about removing an obvious barrier between the sun and the panel.
