Walter Smith Jr.

Commercial Foreman

My name is Walter Smith Jr. I am 24 years old, engaged with two kids and a dog. My hobbies include wood working and home theater/ car audio projects, when I’m not spending time with the family. As a kid, I would take toys and electronics apart to see how they worked, however I was usually not too good at putting them back together (good thing I have gotten better at it, as I do a lot of that these days). I like to troubleshoot and problem solve anything that tests my brain and cognitive thinking. I also like to think of myself as a bit of a comedian (most others would probably disagree though).

Mark French

Senior Sales Consultant

Outside of my interest in renewable energy, I like to spend my time with my wife of 20 years and my 3 daughters. We live on a small horse farm which accounts for a lot of quality time together. What I enjoy most, however, is the time I spend coaching and watching my girls play the various sports that they are into, especially basketball. For me, this is a short-lived part of my life and I plan to enjoy it as much as possible.


Matt Kaczor

Solar Technician

My name is Matthew Kaczor. I am an outdoor enthusiast who loves hunting and fishing. My love for the natural environment pushed me to attend Paul Smiths College where I graduated with a degree in Biology. Today I continue showing my appreciation for the environment by installing solar.


Dan Ives

Solar Technician

Outside of work I spend most of my time rock climbing. Climbing has been my hobby for a decade now and I spend about every weekend outside doing some sort of activity. I enjoy kayaking, mountain and road biking, as well as hiking and snowshoeing.
