ProVision Solar was founded in 1988 under Hawaiian Electric Industries to take advantage of the growing market for photovoltaic solar systems. In 2003, it was purchased from HEI by Marco Mangelsdorf and Douglas Bath. We are now headquartered in Hilo on the Big Island of Hawaii and we are committed to providing our communities with premier solar-electric products and services for homes, businesses, and organizations.
Originally 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) applications across the Hawaiian Islands. 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.

Had (2) Tesla batteries installed to an existing solar system at my home in Kona, Hawaii. I cannot say enough good things about ProVision Solar company out of Hilo, Hawaii. They took care of everything from permitting to installation and support and were so helpful and professional along the way. Houston and his crew were the most impressive group of workers we’ve ever had here. Would highly recommend them to anyone thinking of installing any type of solar system!

Recently had a residential system installed at our house using 17 panels and a Tesla Powerwall, could not be happier with the system and overall experience. It took a few months from start to finish but that’s to be expected given the circumstances of 2021 and we were kept informed every step of the way. The system powers our whole house, charges our Tesla battery generator and electric vehicle, and sends power back to the grid. If on Big Island, I would totally recommend this company to get you exactly what you want for solar. The crew was very friendly and experienced during the whole process

The entire team at Provision Solar was always pleasant during interactions (phone or in-person), provided thorough information/answers to questions, and provided timely responses to questions or install/service calls. When initially investigating adding additional PV generation and battery backup to our existing PV system I engaged a different vendor, but quickly determined Provision had far superior customer satisfaction and reputation locally. Provision easily accommodated adding the electrical service for an EV charger to the install and kept me updated regarding all permit, equipment ordering

ProVision Solar is the first choice if you are looking for a Solar installer on the Big Island. Professional, customer friendly, work was performed in time as estimated. They took care of all permits and inspections. The most we had to do is to sign the contract. The price we paid was in line with the contract.

Showed up on time, communicate what was being worked on and completed. Very respectful and appreciative. Completed panel installation and connections of electrical panels in less time than originally expected. I would recommend their services. Office staff has been superb, they communicate well and keep in contact of progress. They worked to accommodate payment and needs. Requested to come and install panels earlier than originally scheduled

Hi Kathryne, sorry I haven’t posted this review online yet, but think of
this as the first draft.
Please feel free to share with your prospective customers.
I was looking for a long-standing Big Island-local solar company mostly
because I wanted someone who would be there to service the system instead of
just install and run.
From the first call with Kathryne, I knew I was dealing with a
first-class, professional outfit. No hard sell, just a lot of useful
information about the product, the process, and what it would be like
post-install. I can’t think of any part

We selected ProVision Solar after an extensive review of options followed by 5 proposals. All were competetive on price, experience, appraoch to design and installation, etc. We had a number of good choices. ProVision exceeded our expectations.on all dimensions. Tools for modeling system designs, ROI, expected performance metrics, were excellent and well supplemented by Charlie Fasano, our sales rep who stayed in touch throughout the project. I cannot identify a single needed improvement in project management, communications with us and coordination among the many agencies,, contractors and suppliers

I purchased solar panels from ProVision in 2012 and this year added a few more panels and installed a TESLA wall (back up solar battery). Everyone I have ever dealt with, from the sales person to the installers, was professional, friendly, and invested in the success of the project. There were a few technical issues related to getting the older system and the new system to communicate properly, and both Keaka and Keone spent many hours working out the problem. Throughout my association with ProVision, I have been extremely pleased not only with the product but also with the continuing service

Amazing! I couldn’t be happier! Professional throughout the entire process. Sales, management and the installation was second to none. I couldn’t believe how well the entire team worked together. I was so impressed with all aspects of ProVision Solar, not to mention the equipment which is also spectacular. I highly recommend ProVision Solar and would buy again from them any day! Mahalo!

Just completed having ProVision Solar install our solar electric system...without a doubt, ProVision's reputation for professional, quality work was outstanding! Zach our salesman, Emily, Reesha and everyone I communicated with were always personable and helpful. Danny and his team of installers were informative, friendly, and hard working especially during some really rainy days...they were committed in doing a great job. It was a pleasure working with the "ProVision Solar Team" from start to finish and would highly recommend their outstanding and professional services.Much Mahalo

After receiving a glowing recommendation from our insurance agent, we began discussions with ProVision Solar in March 2019. With EVERY email and phone call, all personnel consistently presented themselves as supportive, knowledgeable and timely (my questions were answered within 24 hours, usually within 3!). I was treated as a valued customer, not a numbered account; the company practices and values personalization.
It is now November 2019 and our NEM PLUS system is installed and running. I can quote neither specs nor savings at this point BUT I can commend their professionalism and highly recommend

So far only 2 stars because of poor communication. I will update once the job is complete. Sales people responded right away when I called. We thought it over for a day or two, then decided to proceed. We provided all the required paperwork and the $1000 deposit. Then we heard nothing. I called a month later to see if they were waiting on anything from me. The guy on the phone asked if I turned in all my paperwork (which is what I was asking him), then he told me he would turn it over to our salesperson. Got a call later in the day and they're suddenly ready to do a home inspection right away

Picked Provision after doing research, in other words my words went on line and found several companies, Provision had very good reviews and the Tesla Powerwall. I was told from the beginning it would be a lengthy process and I was kept informed all along the way. The technicians have done an excellent job with the installation and now just waiting for the final inspections so we can turn it on!

Our new solar system came online today and every step of our interactions with ProVision has been a great pleasure. Everyone from Zachary, our salesperson, to Emily the office manager, and Matt and Houston the installers, to every person on their crews was competent, friendly, professional and just plain nice. We were informed what to expect at every step of the way and their estimates about the timing for each step was spot on. When HELCO came out to do the inspection they asked who had done the work. When we told them it was ProVision they said, "Oh yeah, they're great." I

I was new to the Island, just purchased a house and heard horror stories about getting solar, however I knew it was a necessity. I met Kim at ProVision through business and when I talked with her about solar I could tell she was very knowledgeable, passionate and confident that her company and products were the best. All the staff were fantastic and very helpful during the entire process. I am very satisfied with my service and recommend that anyone looking for solar give ProVision a call.
