Being verified. We could not confirm this on an official source yet. Details are held as unknown.

Trackers report Hawaii plug-in solar bills in 2026 (SB 2902, and HB 2486 with a registration requirement) that did not pass. The Hawaii Legislature's website blocked our requests, so we have not confirmed their final status.

The rules

Hawaii has no enacted plug-in solar law. There are no state rules to list; your utility's interconnection rules apply.

What could it save?

For an 800 W panel kit at Hawaii's average residential price of 44.27¢/kWh (September 2025 – August 2026 (12 months)):

Ideal tilt (20°, south): 1,298 kWh a year: about $396 typical (69% used at home), up to $574 best case (100%)
Vertical railing (90°, south): 558 kWh a year: about $171 typical (69% used at home), up to $247 best case (100%)

"Typical" uses HTW Berlin's model for an 800 W system without a battery; exports are assumed to earn nothing. Solar data: NREL PVWatts for Honolulu (capital). Try your own numbers · Is it worth it? · Railing vs tilted
