ProVision Technologies, Inc

September 19, 2007

Woodbury Inspection Group Inc. has a reputation for being very particular with all aspects of construction and related installations. Photovoltaic systems are no exception. We expect the best and settle for nothing less. It is for this reason that we chose Provision Technologies to install a net metering system on one our
personal residences in Kamuela.

Three things sold us on Provision.

Product:
Provision’s product was far superior to that of other competitors. The Sunpower equipment installed was a huge selling factor. It was more efficient that other brands, had better warranties, and provided more installation flexibility.

Service:
Douglas Bath, Marco Mangelsdorf and Jessica Shweig ensured that our questions were answered in a timely manner and definitively. Through every aspect of the transaction Provision was professional and conscientious.

Installation:
As consulting inspectors we know what defines a good installation. Provision kept the site clean and organized and ensured that every aspect of the installation was meticulous. The workmanship of the installing electrical sub-contractors that Provision used exceeded our expectations. The performance of our system tells the rest of the story. We have had 9 months of continuous total offset of our electrical usage. We expect to have full return on our investment in roughly 5 years and have added value to our home while doing our part to offset our carbon foot print. Go green! Go Solar! Go Provision!

Respectfully,

Alex Woodbury

Last year I installed a ProVision Technologies solar electric system on our auto dealership, Island Dodge in Kahului and I'm very glad I did so. ProVision provided skilled design work, top quality components and coordinated the installation with the electrical contractor. I was very impressed with the professionalism of the staff at ProVision, and would recommend you highly to those who may be considering solar electric for their home or business.

I was quite satisfied with the 32 kW system I installed in 2003. So satisfied, in fact, that I decided to expand the system to 52 kW this year. The decision to install a solar electric system not only made sense from an environmental standpoint, it also made good financial sense. This an investment that will pay for itself in a short number of years, and continue to provide clean, green power to our business for decades to come.

I can tell you that I carefully considered this investment, and I am completely confident that I made the right choice. I would certainly recommend ProVision Technologies for their competent staff and commitment to customer satisfaction. If a business owner is interested in pursuing an excellent investment, they should consider installing a ProVision solar electric system.

Sincerely,
Roy Kitagawa

Dear Marco:
I would like to thank you for assisting Roberta and I in the purchase and installation of a solar photovoltaic net metering system for our home in Hilo. We were very satisfied with all aspects of the transaction. We found your staff to be extremely knowledgeable, professional, and committed to our satisfaction. ProVision was conscientious in designing the system, selecting the best quality components, coordinating the installation with the electrical contractor, and ensuring our complete satisfaction with the system once it was installed.
We are extremely happy with the performance of our system, and enjoy its many benefits, especially when we receive our monthly electric bill that shows our savings. We would not hesitate to recommend ProVision to others who are interested in experiencing the benefits of solar electricity. As I mentioned to you before, I would be pleased to speak with others who are considering a solar photovoltaic electric system.

Shine on ProVision!
Very truly yours,
Newton J. Chu

Dear Mr. Mangelsdorf:
This letter of recommendation is to acknowledge the service and attention, which the personnel at ProVision Technologies provided to Hawaii Electric Light Company during and after the installation of a 5.4 kW grid-connected photovoltaic system on our Engineering Building in Kailua-Kona. The system was installed in December 2001.

As this system is installed at a highly visible location at our Kailua-Kona baseyard, the quality of the system and installation, provided by ProVision recommended electrical contractor, needed to be exemplary.
ProVision Technologies provided the major components and design for the system in a timely and professional manner. Though the inverter, which was selected for the installation had some new product problems, ProVision was very responsive in addressing the situation with the manufacturer and in satisfactorily resolving the inverter problems. Moreover, after the installation was complete, ProVision personnel worked closely with us to make sure that the PV system was operating at its peak efficiency.
I can wholeheartedly and without reservation recommend ProVision Technologies as an eminently qualified and professional solar design firm.

Sincerely,
Clyde H. Nagata, P.E.

Dear Marco:
I m taking this opportunity to let you know how pleased we are with the ProVision solar electric system that was installed on our facility last year. As a business owner here on the Big Island, I'm looking for investments that make good economic sense and offer high value. Our grid-connected photovoltaic system made for a great investment and has dramatically lowered our electric bill. Over each of the past several months our net kilowatt-hour bill has been reduced to zero.

I also want to commend you and ProVision for providing us with detailed responses to our questions when we first considered installing a solar electric system, the prompt follow through in arranging for the installation and ProVision's supervision of the project from to start to finish.

Being one of the first Net Energy Metered solar electric pioneers here in the state, we were excited to take advantage of this new program. Our ProVision system has exceeded our expectations and we can heartily recommend ProVision Technologies as a solar electric system provider.
Aloha,

To Whom It May Concern,
This letter is wholly unsolicited. After my 3rd purchase at ProVision, it really came home to me how pleasant and positive the experience has been each time, and how on all countsservice, price and cordiality, I've been well taken care of by everyone in the office.

In particular, Marco mapped out a complete solar-electric system for me, even though my purchase amounted to just a few panels and components. He spent considerable time on several occasions both advising and helping me understand how things work. He even told me where to purchase certain components he didn't sell. I had complete confidence that he had my best interests in mind at all times.
I know there's lots of other small-volume solar consumers like myself that do not as yet know about ProVision, and I'll not hesitate to recommend ProVision to them when asked about a place to buy solar-electric systems.

I hope this letter is passed on up the corporate hierarchy so that the efforts of ProVision to expand their market-share in the community are fully supported by HELCO decision-makers.

Dear Mr. Bath:
We have always had exceptionally high electric rates here on Kauai. We began thinking about a solar electric system and found ProVision Technologies, Inc. You provided timely and high quality information that allowed us to fairly assess that merits of the technology.

When we decided to go ahead with project, ProVision supplied us not only with the main components for the system, you also provided all engineering services, vendor relations, and a competitive bid between contractors for the installation. The installation process seemed well coordinated and did not cause significant disruption of our normal business.

In this past year following the installation, ProVision had stayed in contact with us and showed a real interest in assuring the proper performance of our system. Frankly, I was a little hesitant as you're located in Hilo and it's a difficult journey to get to Kauai from there, but you've been more than responsive.
I am very pleased with the service and competence of ProVision and highly recommend you to anyone interested in joining our efforts towards a sustainable energy future.

Aloha,
Charles C. King
President, King auto center

To Whom It May Concern:
Last year we purchased a photovoltaic solar electric system from ProVision. ProVision and Marco Mangelsdorf in particular, listened to our wants and needs, studied our structure, did a good careful design, brought in competent skilled subcontractors, delivered on time and in budget, and followed up well after the installation. We remain very satisfied customers after several months of use.
We're happy to be saving a couple hundred dollars a month on the electric bill, and we're continually finding ways to conserve electricity inside the office, so we can get that bill down to around zero.
We're pleased to recommend ProVision to other clients on the Big Island, and would be glad to answer questions about our system.

Sincerely,
Thomas Plum

Dear Messrs Lee, May and Clarke,
I am taking the liberty of writing to you in this fashion in my capacity as a HELCO customer and a stockholder in HEI. I have enclosed this letter in another one addressed to ProVision (in Hilo) and asked that they forward it to your respective offices.

Last month we had a 3kW photovoltaic system (grid-connected, net-metered) installed at our home in Kailua- Kona. It has been in operation for three full weeks now and we are very happy with it. We have not yet received our monthly HELCO bill and so we do not yet know how it is effecting the bill financially. But, we have now produced 189 kWh of electricity and we are very happy about that.

The particular reason for this letter is to compliment your staff at ProVision, most especially Mr. Marco Mangelsdorf. Marco was very helpful and very professional. He answered all of our questions, provided us with literature and product information, and oversaw the installation of the system. We are aware of the fact that other companies claim that they can do it cheaper but we felt more comfortable dealing with a thoroughly professional (and professionally through) company. We were not as knowledgeable about electrical contracting and the installation of PV systems as perhaps some other people may be. But, we feel very confident that we avoided many possible pitfalls and were happy that the permitting and inspections proceeded so smoothly. We really do feel that Mr. Mangelsdorf saved us a lot of potential problems and eased the whole project considerably. This system represented a considerable investment for us Over $23,000.00 so we were very anxious to have it done well. We think that is was, and that Marco is a valuable asset to your (our!) company.

We look forward to many years of production from our PV system.

Sincerely,
Larry & Kathy Riggs
Kailua-Kona

Dear Marco:
I want to take this opportunity to thank you for all the help we received in choosing a complete solar system for our home. Every one of your staff members was helpful and very knowledgeable. You all took the time to make sure that every aspect of the system matched our particular needs. When we needed specific electrical engineering plans, you also referred us to Donald McLemore, an excellent electrical engineer. Your prices were very competitive as I shopped around a great deal. It was not only the price but the great customer service that made our decision easy.

I had many questions throughout the process of choosing and installing our unit and you never failed to provide technical support in a very positive and friendly manner. You spoke in a language that I could understand! My husband and I both felt that you went above and beyond the call of duty to insure that our job ran smoothly. It was our first experience with solar and you made it very easy and understandable for us.

We know we made the right choice coming to ProVision Technologies Inc., as we have been using our system for over a year now and it is providing reliable power for our home. We also appreciate the fact that ProVision has been there for us and will continue to be there for us should we have any questions in the future. We recognize that you are not the type of company that makes the sale and then leaves people high and dry. That is a commodity in today's solar market!

We have referred you to many friends and will always highly recommend you to anyone who is looking to provide solar energy for their home. Thanks again for your outstanding products and service.
Regards,

Debra Romeo
