In Hawaii, the average commercial electricity rate is about 39.2¢/kWh — above the U.S. average of roughly 17.6¢. Because a solar system's payback is driven mostly by the utility rate it offsets, Hawaii's high rates make business solar a strong bet in 2026.
Hawaii uses net billing — exports are credited below the retail rate. That lengthens payback versus full net metering and makes pairing solar with a battery (to use more of your own production) materially more attractive.
Businesses use the Section 48E commercial credit (≈30%, up to ~50% with adders) plus first-year bonus depreciation — together typically recovering ~45–55% of project cost. Construction-start timing matters; verify before acting.
For a typical Hawaii business spending about $1,500/month on electricity, our model estimates a 32.8 kW system costing roughly $47,568 after incentives, paying back in about 2.6 years, with on the order of $402,448 in 25-year savings. These are estimates built from Hawaii's real electricity rate — get a quote to confirm your numbers.
Businesses in Hawaii should weigh construction-start timing for the commercial credit and confirm whether the project qualifies for the domestic-content or energy-community adders, which can lift the credit toward 50%.

Yes — Hawaii businesses use the commercial pathway: the Section 48E credit (≈30%, up to ~50% with domestic-content and energy-community adders) plus first-year bonus depreciation.
Hawaii uses net billing (exports below retail). That affects how the power you export is credited and, in turn, your payback — full retail-rate crediting is most favorable, while net billing makes pairing solar with a battery more attractive.
At about 39.2¢/kWh, Hawaii's commercial electricity rate strongly favors solar economics in 2026. Run your address through the calculator above for a source-backed estimate of system size, net cost, and payback.
