Switching to solar power in Oahu isn’t just about going green — it’s about protecting yourself from rising electricity costs and maximizing your home’s energy efficiency. But with so many solar companies in Hawaii, how do you choose the right one?
Here’s your guide to finding the best solar companies in Oahu — and why local experience matters more than you might think.
Why Going Solar in Oahu Makes Sense
Hawaii has some of the highest electricity rates in the United States, averaging over 40 cents per kilowatt-hour. Combine that with year-round sunshine, and it’s no surprise that more homeowners are investing in solar.
Benefits of going solar in Oahu include:
-
Lower utility bills (often 60–80% savings)
-
Energy independence from HECO rate hikes
-
Increased property value
-
Hawaii state & federal tax credits
What to Look for in a Solar Company
Choosing a solar installer isn’t just about who offers the lowest price — it’s about long-term reliability and performance.
A. Licensing & Certification
In Hawaii, legitimate solar contractors must be licensed with the Hawaii Department of Commerce and Consumer Affairs (DCCA) and meet electrical & construction requirements. Look for NABCEP certification for additional credibility.
B. Warranties & Guarantees
Top solar companies offer:
-
Product warranties (25 years for panels)
-
Performance guarantees (ensuring your panels produce as promised)
-
Workmanship warranties (covering installation quality)
C. Local Experience
Hawaii’s salty air, tropical storms, and high humidity can damage poorly installed systems. Local installers understand corrosion prevention, hurricane-rated racking, and HECO’s net metering rules.
