Thanks for posting your experience and breaking it down Barney style.
If I was patient the square tubing would have been bolted as well, but i didn't take the time to think of a bracket and didn't want to spend time on a ladder trying to match drill through thick metal.

From my memory, new solar panels are warrantied for like 25 years with guarantee of 80%. 5-7 years is a huge delta from that. I should be able to tell you after a year if the efficiency is dropping as bad as you are saying, that is approximately 10%/year, should be pretty obvious.
So far i am achieving exactly what i estimated. Ill update next week after 1 month operation.
The federal tax credit is easy, you enter the total you spent on one line on tax form. I imagine this stupid inflation reduction bill is going to add additional credit.

This all the way. Hard to know u til I see this kind of detail.
