“I’ve known Dan, the owner of HNu Energy, for 18 years now. We actually started working together selling lighting products, so I already knew he was a very dedicated and knowledgeable guy. HNu Energy is a family business with a solid reputation. Their dedication has been recognized with a Maui County APEC award, and they have even worked with prestigious organizations like NASA and the US Military.

When I decided to check out solar options for my home, I got three offers on the table. But let me tell you, HNu blew the competition away! The other offers couldn’t match the flexibility and choices that Dan’s company brought to the table, especially with their awesome Franklin battery option. So, naturally, I went with HNu Energy.

What sets HNu apart is its engineering-based approach compared to other companies that are primarily focused on sales. This distinction ensured that I not only got the best price but also the highest quality of service. I had had a disappointing experience with another company previously that had installed solar panels on top of cracked tiles without letting me know. This negative encounter made me appreciate the educational and hands-on approach of HNu Energy even more. During the installation process, the team went above and beyond, even fixing broken tiles and repairing a damaged gutter. They not only installed the system but also took the time to educate me about how it works. These additional services were unexpected but greatly appreciated and are a testament to their integrity. I could not recommend these guys enough! Go green, go HNu!”
