    Awesome experience working with STI Solar Hawaii, they installed Solar PV, AC, and battery backup. The installation went very smoothly and work was high quality, no issues after installing. For Oahu residents I would definitely recommend their services!

    I stopped by the condo late afternoon after the install was completed, when the condo is usually getting quite hot - and boy, does the attic fan help! Looks great, and is also so quiet. Thank you for a job well done, and for being so conscientious about making sure it was going to be a good fit for that location and also that I was aware of the potential drawbacks. Much appreciated!

    STI Solar put together an Enphase off grid system for my tiny home on the island of Kauai.Devin and Chris from STI answered all my questions and concerns about my system.Matt & Graham from STI Solar/Kauai installed it and walked me through the instructions and the phone app. They were professional and got the job done. The Enphase system is awesome and meeting all of my power needs.I would highly recommend them.Thank you STI Solar, Roofing & Air conditioning.Steve

    STI was absolutely fantastic!! Graham came out on time and was a great help. He was very personable and at the same time he was very professional. Graham was super helpful with different opinions I should consider but was in no way pushy.My phone calls to STI were answered promptly.STI is the real deal!!Todd

    Great job installing our 26 panel PV system, along with solar water heater panels. We recently had Tesla backup batteries installed as well. The service cost was reasonable and the PV reduced my electric bill substantially.

    I love my solar and power wall!! Chris was wonderful to work with. He immediately addressed our concerns and was always available to answer questions. It is because of him I give this company 5 stars.

    “I had a good time with your crew. I have never had a “contractor” work at my house, I would handle any thing myself. My biggest concern was having a “crew of laborer’s” show up to bang out an install, but your crew was very professional and gave me the feeling that we were friends and working together. They did not seem to mind my standing over there shoulder and asking questions, it was a great experience.

     

    Should you ever need any resources please feel free to call me, I am always happy to help.

     

    Thank you again Devin and please express the same Chris and you crew.”
