Are Solar Panels Impervious Surface

In addition to these impervious surfaces all solar panels in the array should also be considered effective impervious cover for the purposes of calculating the wqv.

Are solar panels impervious surface. The vegetated area receiving runoff must be equal to or greater in length than the disconnected surface e g width of the row of solar panels. This method will be used to determine the total water quality volume that must be treated for permitting requirements. In order to determine the total impervious surface area for the project the z dimension should be used. Solar panels are considered a disconnected impervious surface when water running off a panel is discharged to a pervious surface e g.
