Haleakala Solar has been in business for over 40 years and has installed over fourteen thousand solar energy systems with satisfied customers all over the state of Hawaii. They believe servicing systems is just as important as installing them. They are a one-stop shop and service anything solar energy related. Haleakala Solar truly stands behind their work, and are one of the few solar companies in the state to have been around long enough to actually back up a 25 year warranty.
