49% of Oahu's single-family homes now make their own electricity — 118,841 systems across five island grids. The utility that has to absorb it publishes no figure for how many of its own meters can see them.
what does this mean?
The strongest source is the operator's or the city's own reporting — an official report, dataset or press release. It grades who did the looking — not how well the project went.

Hawaiian Electric's grid-modernization programme had connected 118,841 solar systems across its five island grids by the end of September 2025 — enough that an estimated 49% of Oahu's single-family homes now have rooftop solar, 47% in Maui County, 30% on Hawaii Island and 45% systemwide. The company's answer on the network side is the advanced meter, which records interval consumption and is meant to support future dynamic pricing and energy alerts; customers may opt out and keep a monthly meter reader.
📊 Impact
118,841 grid-connected private solar systems across Hawaiian Electric's five island grids by the end of September 2025; an estimated 49% of Oahu single-family homes have rooftop solar, 47% in Maui County, 30% on Hawaii Island, 45% systemwide, with the share of residential customers with solar more than doubling over the previous decade (utility figures).
🎓 Lesson
The number the utility publishes is the one it collects at the interconnection desk. Adoption is counted to the individual system; what the grid then did with that power — curtailment, exports, voltage — is not reported in any of these pages, and neither is the advanced-meter rollout the entry's network story depends on: no count of meters installed, no coverage share, and an opt-out that means the coverage can never be complete by design. A saturation figure and a visibility figure are different claims, and only the first one exists here.

Known limits of this passport
- Publisher names and source languages have not yet been classified; domains are recorded without guessing.
- Existing source notes are descriptive locators, not page- or paragraph-exact citations.
- A missing archive, publication date or content hash is shown as null rather than inferred.
- The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
