Client Testimonials

Mike and his team were very easy to work with and did a fantastic, clean installation of my solar roof panels and components. I would definitely recommend them over any of the "big companies" that are around. The quality of work is high and the pricing makes more sense with Mike.
--Brett Fisher
Michael Purnell was expert and thorough in developing a plan for 32 solar panels. Since this was my first experience with solar, he was patient and responsive in walking me through the process and options. He and his crew was professional in the installation, which required reinforcing the shed and placing complex electronics, which passed inspection without issue. Michael also had to navigate the process with the utility company, and did so with persistence until the paperwork was processed. Afterwards Michael diligently followed up with me and even made a video about how to access online reports. I was uncertain at first about solar, but am now very happy with it when I see the daily kwh production. I would not hesitate to recommend Green Prepper to anyone considering working with him.
--Jeff Rosen
This was an experience like all contracting projects should be. Mike was very accommodating when we were deciding on what we wanted and even more impressive when we made a significant change after the project started. He kept us informed every step of the way even when weather or traffic delayed him for an hour. I would recommend Green Prepper without hesitation.
--Cliff Jarrett
I was very pleased with the professionalism and low key manner of Mr Purnell. He answered my questions in a timely manner. The work was completed as he promised.
--Linda Mellon
It was a pleasure to work with Mike and the crew at Green Prepper for our solar project. Mike was very patient during the process and truly evaluated our needs and designed our system to meet those needs. There was never any pressure, just pure interest in making sure we got what we needed. Our process took almost two years because of some structural improvements needed to our house. Mike continually updated our design based on our needs and requirements and kept us informed about the solar market. He is extremely knowledgeable and thinks of the client first. I HIGHLY recommend them for your solar project. We couldn't be happier with the result, and look forward to years of harvesting energy!
--Jason Carbaugh
We got a quote quickly with a walk-around and information about our options. From there, once we signed on, things moved quickly. Now, we like to make occasional trips to the electric meter or online to see what's happening with the array. It was nice to feel like even though we're a small array, our business was important.
--April Leese
I'm so glad we went with Mike to install our system! Such a nice guy and extremely knowledgeable about the equipment and process. He did a really careful job of explaining the setup and his craftsmanship on the install was top notch. I have no idea how the national companies are getting business. They're literally much more expensive for the same equipment, and they use subcontractors who may or may not have ever done the work before. Mike is punctual, good communicator, honest, and nice to deal with. Highly recommend.
--Tom Thorne
Greenfield Technologies (Green Prepper) installed our system in a hassle free and timely manner. Mike walked us thru the process from the initial consultation to completion with a pressure free demeanor. He took the time to explain the steps of the process and completed all the necessary paperwork. All we had to do was agree to move forward with the project. Since installation, the system has exceeded our expectations. Although the system was installed after the prime producing months of the year, it still managed to cover 97 percent of our electrical usage during the month of October, this in spite of extended periods of gloomy weather. With this in mind, we can't wait to see what the system can do next summer. We highly recommend Mike (Greenfield Technologies) and would encourage anyone considering solar to contact him regarding a consultation and evaluation.
