Solar Panels: how to prep roof surface for 3M tape
For those of you who used 3M tape to secure the panels to the roof - can you share any tips and/or lessons learned? I'm planning to mount four GS100 panels purchased from AM Solar this weekend and would appreciate any thoughts.
For now, my plan is to thoroughly wash the roof sections under each of the rocker feet with biodegradable all-purpose cleaner. Wondering if I should be using something more potent such as rubbing alcohol or other chemical cleaning agent? I'm concerned about anything too strong doing damage to the roof surface.
Thanks in advance for any comments.
