ProVision Solar Inc. was incorporated as ProVision Technologies, Inc. in 1998 under Hawaiian Electric Industries to take advantage of the growing market for photovoltaic (PV). In 2003, Marco Mangelsdorf, one of ProVision’s original employees, and his childhood friend, Douglas Bath, purchased ProVision from HEI and have been at the helm ever since. ProVision is headquartered in Hilo on the Big Island of Hawai’i. Today, ProVision Solar serves the Hawai’i community by providing premier solar electric products for homes, businesses and government applications.

Since 2005 ProVision has been a Premier Dealer for SunPower Corporation in Hawai’i. SunPower produces the world’s most powerful solar with the highest efficiency solar electric modules in mass production on the planet. Our SunPower line includes 250 Watt, 327 Watt, 335 Watt and 345 Watt modules with industry leading efficiencies of 20 to 21.5%. We also offer Japanese-engineered Kyocera Solar modules.

We are proud to be the only solar electric firm in the state operating our work vehicles on 100 percent reclaimed bio-based biodiesel from our friends at Pacific Biodiesel. Bob and Kelly King and the crew at Pac Bio have been pioneers in the field of producing B-100 biodiesel by reclaiming waste cooking oil around the state. With operations on O’ahu, Maui and the Big Island, Pacific Biodiesel ( is leading the way toward greater energy independence for our Aloha State and ProVision is very pleased to be able to run our fleet on this Hawai’i-based renewable fuel.

The ProVision staff, which includes industry leaders who have been working in the renewable energy field since the 1970s, is committed to providing our customers with the highest quality products and unparalleled service. We are a fully licensed and insured electrical contractor (C-13), the only Hawai’i state contractor license classification which can obtain the necessary electrical permits to install PV systems from start to finish.
