Delaware solar permitting
Grade distribution
Overview
Every Delaware county is scored on the SitePath solar permitting index. More than half sit in the C range — moderate risk with meaningful process uncertainty. A sizeable minority are rated D or F — high to very high risk, often due to active moratoria, restrictive setback ordinances, or strong local opposition.
The most favorable jurisdictions in Delaware include New Castle County (grade C), Kent County (grade C), Sussex County (grade D). The most challenging include New Castle County (grade C), Kent County (grade C), Sussex County (grade D).
Delaware's RPS framework (RPS 40% by 2035) has a mixed effect on local solar permitting: state incentives can accelerate projects, but county boards often act independently of state policy direction. No Delaware counties currently have an active utility-scale solar moratorium.

Every U.S. county is scored 0–100 on solar permitting risk (lower is friendlier to development). The grade is a weighted composite of compliance stringency, market saturation, regulatory trajectory, and data uncertainty. Every figure traces back to a primary government document.
