Hawaii has the highest electricity rates in the country — which is why solar isn’t just a luxury, it’s a necessity for many island homeowners. With consistent sun, strong incentives, and a grid that’s evolving toward self-sufficiency, solar systems (especially with batteries) offer real freedom. It’s no surprise Hawaii leads the nation in solar adoption.
Choosing the right installer matters just as much as choosing to go solar in the first place — the difference between a company that’s licensed, experienced with Hawaii’s Customer Self-Supply and Grid-Supply programs, and backed by a real workmanship warranty and one that isn’t can add up to thousands of dollars over the life of your system. Below, you’ll find Hawaii’s solar companies compared side by side, including which ones have completed EnergyScout’s verification process, so you can start your search with a shorter, more confident list.
EnergyScout tracks local and national solar companies serving homeowners throughout the state. Use the directory below to compare installers based on experience, service area, products, certifications, and other company information.
Companies displaying the EnergyScout Verified badge have completed an additional review process that includes a direct interview, screening customer feedback, and providing evidence of completed installations. Verification provides another layer of information when comparing solar companies, but homeowners should still evaluate multiple installers to find the right fit for their home.

Hawaii’s Solar Leadership and Necessity:
Hawaii ranks #15 in residential solar installations and generates over 21% of its electricity from solar — one of the highest percentages in the nation. The state’s high solar adoption is driven by economic necessity: Hawaii has the nation’s highest electricity rates, often exceeding $0.35-$0.40 per kWh, because nearly all fuel must be imported. Hawaii employs over 2,400 solar workers, and the solar industry has become a critical part of the state’s economy and energy independence strategy. From Oahu to Maui to the Big Island, solar infrastructure is well-developed and widely adopted.
Economic Imperative and Grid Evolution:
With electricity rates 2-3 times the national average, Hawaii homeowners see solar payback periods of just 5-8 years — among the fastest in the country. The state’s Customer Self-Supply (CSS) program replaced traditional net metering, requiring new solar customers to include battery storage and limiting grid exports. This policy shift makes batteries essential rather than optional for most new installations. While this increases upfront costs, it also provides maximum energy independence and protection from Hawaii’s expensive grid power. Solar + battery systems in Hawaii often offset 80-100% of electricity costs, delivering massive long-term savings.
Island Living and Energy Resilience:
Hawaii’s isolated island grids are vulnerable to disruptions from tropical storms, high winds, and equipment failures. Extended power outages can be serious, particularly in rural areas or on outer islands. Solar + battery systems provide critical energy security, keeping homes powered even when the grid fails. Hawaii’s consistent year-round sunshine means solar panels produce excellent energy in all seasons, and modern battery systems can store enough power to run a home through overnight hours and cloudy periods. For Hawaii residents facing the nation’s highest electricity costs and island grid vulnerabilities, solar + storage isn’t just smart economics — it’s essential for energy independence and financial stability.
