Power outages are common in Hawaii and some last over 6 hours and even days. Even if you have a solar PV system, you’ll be in the dark unless you have battery storage. Today batteries are also for self-supply which saves you even more money.

Testimonials
“I am very please with the solar AC system installed by STI Solar. When I considered solar AC, STI Solar’s owner Devin Ruiz was responsive and knowledgeable – answered my questions, promptly scheduled an on-site visit to assess my requirements/discuss options and provided detailed equipment stat sheets to include warranty info. He even put me in touch with his CPA to ensure my solar tax credit questions were answered accurately. The cost for the 12K BTU and 18K BTU split system installed was lower than other estimates received and there was never any sales pressure. Plus, STI Solar is a local business supporting many local organizations, so it is satisfying knowing my solar investment helps both the environment and the Hawaiian community.”
“Mahalo to STI Solar for our solar PV and solar hot water systems. My wife and I were very pleased with their professionalism and customer service. They did what they said they would do and more. They offer a great value and their finance programs are really saving us a lot of money on our energy bills. Nice to see professional contractors like STI on Kauai. We will be referring them to our friends and business colleagues at our real estate office.”
“STI Solar delivers an amazing experience for all your solar needs. It starts with dedicated time explaining the how and why of what would be done and the different possibilities, maintained communication thru the permitting and installation process, owner personally validated quality of work and they followed-up after system startup to ensure everything was working. Overall a wonderful experience where we felt great about our decision to install solar and the company we chose. We have already referred STI Solar to several friends.”

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!
