Energy costs in Honolulu, HI
Energy prices are published by state, not by city, so the rates and bills below are Hawaii figures and apply to Honolulu the same as anywhere else in the state. The solar production is different: that is modelled for Honolulu's own coordinates, and it varies a lot within a single state.
Solar at Honolulu's coordinates
9,513kWh a year from 6 kW
That is 10% less than the Hawaii average, which is the sort of gap that makes a state figure the wrong one to plan with. At 52.00¢ a kilowatt hour it pays back in about 2.5 years with full net metering.

Common questions
What is the electricity rate in Honolulu?
52.00¢ per kilowatt hour. That is the Hawaii residential average from the EIA — rates are published per state, not per city, so it applies across Honolulu and the rest of Hawaii alike.
What is the average electric bill in Honolulu?
About $215 a month for a typical Hawaii household. Again this is a state figure: EIA reports revenue and customer counts by state, so a city-level bill would be an invention.
Is solar worth it in Honolulu?
A 6 kW system at Honolulu's coordinates is modelled at about 9,513 kilowatt hours a year, which pays for itself in roughly 2.5 years at Hawaii electricity prices with full net metering. This one is genuinely local — production is modelled for this point, not the state.
