I had ad energy install my panels about 2 years ago and I couldn't be happier with them. From the start I could tell they were honest about what they do and not just salesman trying to push as many panels as they could... When install day came the crew that showed up were super friendly and professional. You could tell they all enjoyed what they did and installs were a kind of art to them. I was very clear I wanted to see no wire runs on the exterior of the house and I wanted a clean look. They went to extremes to run everything through attic space and threw walls so I had no visible conduit on the outside. One of them even crawled through a 12"x12" hole to achieve this. When the panels were finished installing I ended up not liking the clips on the outside ends of the panels because I could see them and the rails slightly (I'm very particular and hard to please) so I told them how I felt about it and they ordered new clips for me, and a week later came back took off the end panels, cut back the rails so they'd be invisible and put the panels back on with the new clips. I was very happy with the new clips and they didn't charge me a dime for the change. They were happy I was happy. Over the years I've had a few critter guards come lose and I simply contact my salesman Mike and a truck comes out and fixes it no problem. Now I need them to come remove the box that's located on the outside of my house so I can replace siding and then reinstall the box and they are coming to help me for a super fair price. Some companies I've seen come and put the panels up as fast as they can to get to the next job, conduit running down the sides and even across the roof sometimes. These guys are true craftsman and take pride in what they do. Many of my installers said they came from other companies that they hated working for because they hated just throwing panels up super fast regardless of how good of a job they do. Ad energy allows them to take their time and do a good job. I appreciate that and wish more companies worked like them.
