Hello everyone. I have two strings of 545W panels consisting of 6 each for now.
Panels are 1.1m wide and 2.2m tall roughly. One string is on an IBR roof, and the other on a tile roof.
Question is how many rail mounting brackets do I really need? Obviously its expensive, but how much do you realistically need to secure them?
I want to have space for a 7th panel on each string, so I figured 8 brackets each (4 top and 4 bottom rail) should be enough?
Thanks in advance
