Hawaii Incentives & Rebates

Hawaii has the highest electricity costs in the US (making solar highly cost-effective even without incentives). Property tax exemption for solar. Net metering replaced by Customer Grid-Supply/Self-Supply programs. Note: The federal 30% residential solar tax credit expired December 31, 2025 for customer-owned systems. Solar leases and PPAs may still offer indirect savings from the commercial tax credit. Check with a tax advisor for current eligibility. Source: DSIRE, EnergySage.
