How we calculate these numbers: All data comes from Honolulu DPP permit records, cross-referenced with our 68,000+ permit database. Contractor permit counts are deduplicated across both the primary and electrical contractor fields. Costs reflect the value declared on the permit, which closely tracks final installed cost for residential systems.
