What do El Cajon solar arrays need?
East County brings desert dust from the I-8 corridor and Anza-Borrego pull-throughs. Panels here pick up the most visible soiling in the county — production drops of 20–25% are not unusual without quarterly cleaning. Hard-water spotting from sprinkler overspray is also common in El Cajon and Santee.
