happy with my decision

I found the team at Wattson Home Solutions to be very professional. Very friendly people. Installers did a fantastic job and did not leave a mess on my property. One of the electricians also helped me with a few light switched in my kitchen. Great team. Also they helped me install minisplits as part of the project.

Let the savings begin

Just had the team here at Wattson Home Solutions perform my install last month. So far the first month has been pretty good. I did have snow covering the panels for most of the month but I came on here because I was very happy with the install crew. Nice guys who did great work. The whole process with this company was very straight forward.

Awesome service

Energy Monster guys (Kyle in particular) were great with the coordination, transparency. They did a great job with the solar roof panel installations. Step by step they guided me throughout the process. I had a smooth sail and got a good response even after the installations. I strongly recomend Wattson Home solutions (previously known as Energy monsters) to all the new solar enthusiasts! Good luck.

After chatting with multiple companies I ended up going with Wattson Home Solutions. I worked with Kevin who was very helpful and informative. He was able to answer all of my questions in a very clear manor that I was able to understand easily. I was also able to package a ductless minisplit system with Wattson Home which was a big plus for me. These guys can do it all at a very fair price. I have already referred them to some family members.

Very happy

I was referred to Wattson Home Solutions from a few of my neighbors who also went solar with them. We were originally approached by a door knocker and were immediately turned off on solar. We thought they were all douchebags. After our neighbor recommended Wattson to us we were relieved after the first conversation. It just felt like these guys werent just trying to make a sale but wanted us to be completely happy and educated about our system here. They made us feel very confident about our decision. Even after the install our initial point of contact - Kevin - is still able to offer us help and information for whatever we are looking for. At this point almost our entire street has used these guys.

Easy communication

Very happy with the team at Wattson Home Solutions. They did what they said they would do - without ever being annoying like alot of these other solar companies. There was a few weeks in between when the system got activated and the installation - but these guys gave me a heads up on that delay which was much appreciated. They kept me in the loop at every step. I feel super comfortable with these guys and would recommend them to anyone.
