They are great. The guys at Progressive Power Group are just so nice and they did a wonderful job. They answered everything honestly and professionally. I recommend them to a lot of people. I have had several estimates and Progressive's are always the most honest and reasonable. And I can call 24/7 if I have a problem, which they almost always solve over the phone.
I had originally installed 12 panels and I added another 6 this last winter. My electric bill has gone way down. They are a great company, and I love all of them.
