Solar Power Systems (PV)

Water Heating Systems



Over 8000+ Systems Installed…

I originally called Solar Kauai for problems with my old solar water heating system which they repaired. I decided to go for a PV system. I’ve had my PV system for four years and I can’t believe I didn’t do it sooner. It works trouble free and has saved me so much on my electric bills....not to mention all the tax credit savings. It’s the thing to do if you live here on Kauai.

Installed or new system very quickly and efficiently also gave us the right recommendations about what was needed for our vacation rental!

Very responsive on system scoping and pricing. Pricing was very competitive, and they didn’t over-specify the system, which some competitors did do. Were flexible on doing installation during a tight window of availability at my home, they handled all permitting and utility interactions without any snags. The system has been working without incident for 2 months, generating output that is in line with what was promised. Elliot was an excellent communicator as the project lead. Definitely recommended.
