Alternate Energy Hawaii installs on Oahu from our Pearl City headquarters. For neighbor island homeowners, we provide comprehensive resource guides with island-specific rates, production data, incentives, and contractor selection advice — plus free tools that work for any Hawaii island.
We serve all Oahu communities with in-house licensed crews for solar, battery, AC, roofing, and electrical. Select your area for location-specific information.
