Haleakala Solar & Roofing

Haleakala Solar & Roofing is one of Hawaii’s longest-running solar companies, established in 1977. The company’s Oahu office is located at 99-1265 Halawa Valley St in Aiea, serving homeowners and businesses across the island. Haleakala also maintains offices on Maui and the Big Island, making it one of the few solar companies with a physical presence on multiple Hawaiian islands. The company was reorganized under local ownership in 2020 and continues to serve residential and commercial customers.

The company combines solar PV installation with roofing services, a pairing that benefits homeowners who need roof repairs or replacement before installing solar panels. Haleakala installs panels from REC and Panasonic, paired with Enphase and SolarEdge inverters. Battery storage options include the Tesla Powerwall. The team is available seven days a week from 7:00 am to 9:00 pm, offering more flexible scheduling than most competitors.

Haleakala Solar & Roofing holds a 4.0-star rating on Yelp from 121 reviews and maintains an A+ BBB rating with accreditation since 2020. The company’s decades of experience in Hawaii’s unique roofing and solar environment gives them institutional knowledge of local building codes, weather conditions, and utility requirements that newer companies may lack.
