ProVision Solar, Inc. Your Trusted Solar Experts since 1998
Proudly serving the Big Island, Maui and now in Oahu! License #: C-26351 Call or stop by our office on Railroad Ave.

ProVision Solar, previously ProVision Technologies, was incorporated in 1998 and focuses exclusively on solar electric applications in Hawai‘i. Initially a subsidiary of Hawaiian Electric Industries, ProVision was purchased by Marco Mangelsdorf, one of the company’s original employees, and Douglas Bath in 2003. As a fully licensed electrical contractor (C-26351), ProVision specializes in offering

grid-connected photovoltaic systems to homeowners and businesses. Our current focus is on the Big Island, but we also have many satisfied customers on Maui, Moloka‘i and Kauai. Locally owned and operated, ProVision Solar’s staff includes renewable energy veterans with decades of experience, licensed electrical and structural engineers, and skilled sales and customer service personnel. We do not sub out any of our installations; our crews are all ProVision Solar employees. We provide our customers with the highest quality commercial and residential PV packages available. In light of the highest electricity costs in the nation, the abundant sunshine across our Aloha State and substantial tax credits available, the reasons to go solar electric have never been more compelling. We can provide you with the full details on the latest incentives that make solar electric affordable. ProVision Solar has the experience to jump through the County and HELCO hoops so you don’t have to. Contact us and let us design a solar electric system for you. We’re a local business with a great reputation for helping Hawai‘i residents and business owners transition to reliable and sustainable solar electricity. We have hundreds of satisfied customers who are enjoying the benefits of a reliable PV system like lowered electricity costs with clean energy from the sun.
