Hawaii has programs available to offset the costs of purchasing and installing a solar collector system, including the most cost-effective, rebates. There are many additional programs available through the federal government.
Hawaii rebates are available through the public utility companies (HECO and subsdiaries) in the amount of $1000 for a residential solar water heater, and $125kWh for commercial applications. Kauai Island’s rebate is $800 for residences and 50-80% of costs for commercial buildings.
Hawaii Tax Credits
Hawaii offers businesses and residences alike a 35% tax credit to install a solar energy system. Hawaii also offers a 100% tax credit to any equity investments made in Qualified High Tech Businesses.
