Customer Testimonials

“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.”

“We are extremely satisfied with our solar system from STI Solar. The team was very knowledgeable, kept us informed, cleaned the worksite each day and maintained a friendly demeanor even with my dog barking at them every time they passed the back door. We will definitely recommend STI Solar to our friends and family. Mahalo.”

“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.”
