Solar Installation and Review

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. Since installation, the system has exceeded our expectations. This past year (2022) was our first full calendar year with the system. The system has covered all our electrical needs since April, including excess kilowatt hours it created during the summer and fall months that have carried us thru the winter months thus far. We highly recommend Mike (Green Prepper) and would encourage anyone considering solar to contact him regarding a consultation and evaluation.

Local support and cheeep

We decided to get solar in 2020. I got 3 estimates, despaired at the cost of 2 of them, couldn't get a callback from the 3rd , and then found Green Prepper online. Mike and his team were not only the best deal by far but also were prompt and very professional. The prices were so competitive that I asked them to do my parents' house, too. Careful workmanship and super service after the sale. Even a couple of years later he alerts me if he sees anything unusual in our power production (I allow him to track it remotely). I'm going to get him to add to our production capacity so we can run our heat pump from it! Excellent company, great, honest guy to know.

Highly recommended

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!

Ted and Barb’s Ground Mount System

Mike from Green Pepper did a great job with our project - it was a large ground mount system built in Jan 2022 - during build - Mike and folks communicated well with us. Mike told us what days he was coming and how project was progressing - we went live 2/1/22 - our system had an issues that he found monitoring it after it went live and he proved to manufacturer it was their issue to fix - a software one - and they did - highly recommend this company

Green Prepper experience

We purchased an array of solar panels from Green Prepper in July 2021. Mike and his group were courteous and hard working, even in extreme heat. Everything Mike spoke with us about was on point and he has been invaluable in helping us any time we have reached out to us. He is prompt and precise to his word. Our panels are working wonderfully even better than we had anticipated.
