Why Honolulu Homeowners Choose Solar

Honolulu residents on HECO's residential rate schedule pay an average of $0.40+/kWh — more than triple the U.S. mainland average. With strong year-round sunshine averaging 5.2 peak sun hours per day, a properly sized solar system can eliminate 90–95% of your electric bill.

Many Honolulu neighborhoods — Manoa, Kaimuki, Hawaii Kai, Makiki, and Aina Haina — feature older homes with south-facing rooflines ideal for solar. Homes in these areas typically install 8–14 kW systems with 17–30 REC or Hyundai panels and one or two Tesla Powerwall 3 batteries.

Honolulu Permitting & HECO Interconnection

Honolulu permits are processed through the City & County of Honolulu Department of Planning and Permitting (DPP). Residential solar PV installations typically require a building permit and an electrical permit. AEI handles all permit applications, city inspections, and HECO interconnection paperwork — you never have to visit a permit office or call HECO yourself.

Under the current SRE Export program, Honolulu homes receive $0.329/kWh for energy exported during peak evening hours (5–9pm) — making battery storage especially valuable for maximizing your return.
