Alternate Energy Hawaii has been headquartered in Pearl City since 1993. Our office, warehouse, and in-house installation crews are all right here at 96-1276 Waihona St — which means faster response times, same-day site visits, and a neighbor you can trust with your home.
Pearl City is our backyard. We drive past the same Longs Drugs, the same Pearl City Shopping Center, and the same neighborhoods where many of our crew members live. When you call AEI, you are calling a neighbor — not a sales office on the mainland.
Pearl City homes along the ridgeline areas — Pacific Palisades, Pearlridge, and the streets above Kamehameha Highway — get excellent solar exposure. Most homes install 8–12 kW systems. Lower-elevation homes near Pearl Harbor may have more shading, which is why we do a thorough site assessment using satellite imagery and on-site evaluation before recommending a system size.
REC 460W and Hyundai 440W panels, Enphase microinverters, custom roof layout. Most Pearl City installations complete in 1–2 days.
Tesla Powerwall 3 with 13.5 kWh backup. Pearl City homeowners can maximize SRE peak credits by storing daytime solar for evening export.
Mitsubishi mini-split systems up to 33.1 SEER. Pearl City homes without central air benefit most from ductless installations — quiet, efficient, room-by-room control.
CertainTeed 5-Star certified. Many older Pearl City homes need roof work before solar — we bundle both projects under one contract and one crew.
Panel upgrades, rewiring for older Pearl City homes, EV charger installation, and code-required upgrades for solar-ready electrical systems.
Perfect complement to PV. Reduce water heating costs up to 90%. The 35% Hawaii state tax credit (up to $2,250) still applies in 2026.
Pearl City falls under the City & County of Honolulu permitting jurisdiction. Solar and roofing permits are filed with the DPP. We handle every step — permit applications, DPP inspections, and HECO interconnection — so you never have to take time off work to visit a permit office.
Our office at 96-1276 Waihona St #114 is minutes from any Pearl City address. Same-day site visits, fast warranty service, and a team that knows your neighborhood.
Electrical (C-13), AC (C-52), roofing (C-42), general contractor (C-26041). One company handles your solar, battery, AC, roof, and wiring. No subcontractors, no finger-pointing.
Founded in 1993, headquartered in Pearl City every year since. 10,000+ Hawaii homes powered. We are not going anywhere.
