Top was about $5600.00 installed you may notice in the picture I had them cut the hole for the max fan, the top is curved side to side I will be working on solar panel install hopefully next weekend
@John S, I have the same Maxx Fan to install as you. I wasn't sure where I wanted it located so didn't have Fiberine cut it. Also, keep me posted on your solar install. I'm on the fence between rack and roof mounting.
