From Diamond Head to Salt Lake, Honolulu homeowners pay some of the highest electricity rates in the nation. AEI has been helping Honolulu families cut their energy costs for over 33 years — with licensed, in-house crews for solar, battery, AC, roofing, and electrical.
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.
REC 460W and Hyundai 440W panels with Enphase microinverters. Custom-designed for your roof, shade conditions, and energy goals.
13.5 kWh backup per unit. Critical for Honolulu homes during hurricane season and HECO outages. Eligible for BYOD+ payments.
Up to 33.1 SEER efficiency — ideal for Honolulu's year-round warm climate. Wall-mount, ceiling cassette, and ducted options.

35% state tax credit still available. Reduce water heating costs by 70–90% with a solar thermal system designed for Honolulu conditions.
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.
