Hawaii solar leads

Sunlight on an Oahu array

Hawaii’s reference point is the Urban Honolulu census-designated place on Oahu, which stands in for the largest city because the Census Bureau counts Honolulu as a census-designated place rather than an incorporated city. For that point, the PVWatts calculator, developed by NREL and now run by the National Laboratory of the Rockies, gives 5.65 kWh per square meter per day of solar radiation on an array (checked October 9, 2026).

How it was produced: the version 8 default system, a fixed open-rack array tilted 20 degrees toward due south, placed at the gazetteer coordinates of Urban Honolulu and run with typical-year weather from the National Solar Radiation Database. Windward and leeward sides of each island, and other roof angles, give other results, so the number is a shared yardstick rather than a figure for any single roof.

How Hawaii’s utility commission handles rooftop solar exports

Hawaii’s Public Utilities Commission sets the programs under which customer solar and batteries connect to Hawaiian Electric’s grid. Its DER Programs page (last updated August 2025, checked October 9, 2026) explains that Decision and Order No. 40418 finalized two long-term tariffs. The Smart DER Tariff launched for enrollment on April 1, 2024 with two riders: an Export Rider that pays time-varying rates for energy sent to the grid, and a Non-Export Rider with a streamlined interconnection process for customers who use all of their own output. The initial export rates and incentives are to be updated every three years.

The Bring-Your-Own-Device (BYOD) Tariff layers on top of a basic tariff and pays customers, initially those with batteries, for grid services. Its Level 1 rider opened on April 1, 2024; Levels 2 and 3 were to launch later. According to the commission’s frequently asked questions, the interim tariffs (Customer Grid Supply, Customer Grid Supply Plus, Interim Smart Export, Customer Self Supply and the Standard Interconnection Agreement tariff) closed to new enrollment in early 2024, and customers on the first three move to a Smart DER rider seven years after they enrolled.

Two limits follow from the same FAQ. The DER docket programs do not apply to customers of the Kauai Island Utility Cooperative, which offers its own programs, and building permits for DER systems are reviewed by city and county agencies, not the commission. A buyer covering more than one island can treat Kauai as a separate set of utility rules.

Hawaii’s renewable energy tax credit in 2026

The Hawaii State Energy Office’s tax credit page (checked October 9, 2026) reports that the Legislature passed SB 3125 in 2026, signed into law as Act 24. Act 24 changes the state’s Renewable Energy Technologies Income Tax Credit for taxable years beginning after December 31, 2026, adding new eligibility requirements, certification provisions, aggregate credit limits and a future sunset of the credit. The office states that Executive Order 26-02 preserves the credit for 2026 while the legislative changes apply to 2027 and later years, and that guidance and filing instructions will be posted on the same page.

The page gives no credit amount, and this section states none. How the credit applies to a given household is a question for a tax professional. Separately, the commission’s FAQ lists the Hawaii Green Infrastructure Authority’s GEM$ on-bill program, which offers financing for rooftop solar to low and moderate income customers of Hawaiian Electric.

Hawaii counties by owner-occupied detached homes

Each Hawaii county is an island or a group of islands. The table lists the four counties with owner-occupied homes, ranked by owner-occupied single-family detached homes, with each county’s owner-occupied homes and the detached share; Kalawao County shows no owner-occupied homes in the data. Source: ACS 5-year 2020-2024, table B25032 at county level. The table describes housing only and says nothing about where leads come from.

Honolulu County, which is Oahu, has the most owner-occupied detached homes but the lowest detached share, 64.0%: the other 36.0% of Oahu owner homes are attached houses, apartments or other types. On the island of Hawaii, 90.4% of owner-occupied homes are detached houses in the 2020-2024 ACS county data.

What Hawaii solar buyers filter on

Solar buyers in Hawaii usually narrow requests with a short list of lead fields, each tied to the facts above:

• Homeowner status: an owner signs for a system, and owner homes on Oahu include many condominiums.
• Project type: the kind of solar work the homeowner asked about, in general terms; the exact options are set when the solar form is finalized.
• Timeframe: whether the homeowner wants work done soon or is still collecting information.
• ZIP code: the islands and districts an installer serves, set ZIP code by ZIP code.

The filters for Hawaii solar leads are agreed with each buyer during onboarding. Exclusive or shared routing for solar leads is agreed with each buyer during onboarding. See the sample solar lead for the field list.
