Is Solar Still Worth It in 2026? Read the Definitive Master Guide to Oahu Solar Incentives 2026

The federal residential tax credit (25D) may have sunset, but for Oahu homeowners, the savings are just shifting. Learn how to leverage Hawaii’s 35% State Credit and the OBBB program to keep your electric bill at $0.

Navigating the New Solar Landscape on Oahu

If you’ve been watching the news, you know that 2026 marks a turning point for renewable energy. With the expiration of the 30% federal residential solar tax credit on December 31, 2025, many Honolulu homeowners are asking: “Did I miss the boat?”

The short answer: No.

While the federal landscape has changed, Hawaii remains the most aggressive state in the nation for solar adoption. Between the One Big Beautiful Bill (OBBB) and the most generous state tax credit in the U.S., solar isn’t just a “green” choice—it’s a financial necessity as HECO rates continue to climb.

What’s Inside the 2026 Master Guide?

Our team at Hi-Power Solar has audited every available incentive for 2026. In this free guide, we break down:

  • The 35% Hawaii State Tax Credit: How to maximize the Renewable Energy Technologies Income Tax Credit (RETITC)—which remains one of the strongest in the country.

  • The OBBB Strategy: A deep dive into the One Big Beautiful Bill (OBBB) program, explaining how it allows Oahu residents to pay for solar through their utility bill with no upfront cost.

  • The TPO Loophole: Why 2026 is the “Year of the Lease.” Learn how Third-Party Ownership (PPA/Lease) allows you to still benefit from federal credits (Section 48E) that are no longer available to direct homeowners.

  • HECO Grid Services: How to get paid by Hawaiian Electric to share your battery power during peak Oahu demand.
