"I have installed two of these double panel units on a three story addition to our superinsulated home. The instructions were clear and the included template made locating the intake and outlet holes easy. The panels are very well constructed. I only needed to purchase screws to attach the mounting brackets to the wall; everything else was included in the kit. I am quite happy with the output of the panels. Let the sun shine!"
