How this net metering layers inside Hawaii's deep stack

The Hawaii Smart Export Tariff (SET) governs how Hawaii credits excess solar generation sent back to the grid, one of the state's DSIRE-tracked solar policies. Eligibility is scoped to residential customers, with a stated benefit of Time-of-use export rates. DSIRE lists no scheduled sunset, though enabling legislation and appropriations can still be revised year to year.

That baseline is already fast by national standards. Hawaii averages 5.9 kWh/m²/day of usable sunlight and residential rates of 38¢/kWh, producing an estimated 10,337 kWh/year and $3,928 of annual utility offset on a typical 6 kW system costing $20,400. That baseline already implies a 5.2-year simple payback and a 25-year modeled net of roughly $77,800 before this incentive - every dollar this net metering delivers compresses that payback further.

Hawaii bundles a deep incentive stack, so this program rarely stands alone. Hawaii has 4 solar incentive programs indexed in DSIRE, including adjacent options like HI Solar Property Tax Exemption, Hawaii Green Infrastructure Loan (GEMS). The state's net-metering policy is classified as partial, which governs how excess generation is credited and often decides whether a given program is worth claiming for a specific household.
