Hawaii Net Metering and Solar Export Credits

Fact-checked by Sorted & Saved data desk
Updated Data verified Nov 5, 2026

Net billing (exports credited below retail). Net energy metering is closed to new customers; Hawaiian Electric customers now use the PUC's Smart DER Tariff, either a Non-Export option or an Export Rider paying time-varying export rates (highest 5-9 p.m., lowest 9 a.m.-5 p.m.). Earlier programs like Customer Grid-Supply Plus closed in 2024.

What Hawaiian Electric pays for exported solar

For a new rooftop system, Hawaiian Electric credits exported energy at about 13.50¢ per kWh[1], against an average Hawaii residential price of 46.41¢[2]. Every kWh you send to the grid earns this rate; power you draw is billed at retail.

Other Hawaii utilities, co-ops and municipal utilities set their own rates; check your utility's current tariff.

State rules that apply

  • What the rule says: “an export option that allows customers to connect to the grid and receive time-varying compensation for exporting energy”[3]

What it means for sizing and batteries

When exports earn much less than retail, each kWh you use at home as it is produced is worth more than one you export. Size to your daytime and evening use, shift loads (laundry, dishwasher, EV charging) to sunny hours or the plan's off-peak window, and price a battery against the gap between the retail and export rates.

The calculator uses the statewide rule until we add utility rates. See what solar costs in Hawaii.
