Ultimate Off-Grid Solar

Company History

Started in 2015 but over 20 years of experience in designing and installing off grid systems on the Big Island of Hawaii. We have designed and installed thousands of electrical systems and over 300 dedicated offgrid solar power systems here on the Big island.

    • We don’t just sell solar panels and off grid systems, we live on them. We have an active off grid solar system at the store and can tell you what it’s is like to live off grid. For the do-it-yourselfers we can teach you how to setup your own system. Living off-grid is easier than you think.
    • We can help you design a system that is custom sized for your needs. This will help you save money by not purchasing unneeded equipment or having to repurchase and upgrade later.
    • Systems are installed by Mattos Electric licensed electricians. Mattos Electric is a locally owned and offers reliable electric contractors to the homes and businesses in Hilo, HI and throughout the Big Island.
    • Each year Ultimate off grid systems attends several forums, trade fairs, training seminars to keep up to date with the best off grid technology.
    • We carry the best brands that are designed and tested specifically for Hawaii and its unique climate, including Outback, Morningstar, Midnite, Hyundai, Solar World, Outback batteries, Brightway, Interstate, SunDanzer, and Steca.
    • We are friendly and easy to work with and have installed systems for just about every type of off grid power need/situation.
