Maui County Solar Installation Growth 2026: Local vs. Statewide Trends

Walk through any Maui neighborhood today and you'll spot something that wasn't nearly as common a decade ago: rooftops shimmering with solar panels. It's not just a trend, it's a quiet revolution happening one home at a time. If you've been weighing whether now is the right moment to go solar, understanding how Maui stacks up against the rest of Hawaii can help you make a smarter decision, and it's exactly why so many homeowners are searching for the best solar companies in Maui before they commit.

How Maui Compares Statewide

Hawaiian Electric's 2026 mid-year data tells an interesting story. Across the islands it serves, customers added 3,429 new rooftop solar systems in just six months. Oahu led the pack with 2,505 installations, but Maui County wasn't far behind the smaller islands, adding 434 new systems of its own.

That might sound modest next to Oahu's numbers, but context matters here.

Maui's Existing Solar Foundation

  • Maui County already has over 19,000 grid-connected solar systems installed
  • Nearly half of all single-family homes on Maui, about 47%, already have rooftop solar
  • Renewable energy, including solar and battery storage, now makes up roughly 41% of Maui County's total electricity generation

Maui isn't just catching up. It's already one of the most solar-saturated communities in the country.

Why Growth Has Slowed Slightly

Statewide demand has cooled a bit in 2026, largely because the federal residential solar tax credit expired at the start of the year. Add in rising equipment costs from tariffs and new state tax credit caps, and it's easy to see why some homeowners are pausing.

What This Means for You

Slower growth doesn't mean less opportunity. It means:

  • Less competition for scheduling installations
  • More attention from installers who have room on their calendars
  • A chance to lock in savings before utility rates climb further

Making the Right Choice

Not every installer understands Maui's unique grid, weather patterns, and permitting process the same way. That's why local experience matters so much when comparing your options.
