How dirt and soiling reduce your solar output in Virginia
Panel soiling — the accumulation of dust, pollen, bird droppings, and other debris — is one of the most common and fixable causes of solar energy loss. In arid regions, soiling alone can reduce output by 5–15%. Here's what you should know.
How Virginia's climate affects this issue
Moderate soiling risk — periodic cleaning is recommended, especially during low-rainfall seasons.

Related issues
Panel soiling
Dust, pollen, bird droppings, or debris accumulation reducing light absorption. More severe in arid or agricultural areas.
Typical loss: 2–15%
Self-check tip:
Visually inspect panels from ground level. If you can see a visible film or debris, cleaning may restore 2–7% production.
