What dirties solar panels in Valrico
Agricultural dust
Field work east of Valrico raises fine soil that drifts west on dry-season afternoons. It is heavier and more mineral than road dust and settles in a visible tan layer.
Mature tree canopy
Established oaks and camphor on Valrico's larger lots drop leaf litter and sap directly onto arrays, and shade patterns change the whole soiling picture panel to panel.
Well-water irrigation
Many Valrico properties run on private wells with high iron content. Overspray leaves rust-tinted staining that requires pure water and patience, not scrubbing.
Pollen
The same spring oak and pine load as the rest of east Hillsborough, amplified by the tree density on these lots.
