SOLAR ATTACHMENT SURPRISE--NEED SUGGESTIONS
All set to attach the 1st of 2 solar panels. Aluminum roof. Very sturdy. At a vent opening, looked like about 1 1/2 inch plywood. Put a lag screw in and it spun and spun and spun, etc. No grab. Knock...

I attached our 185W panel with 3M VHB tape. Surface prep and enough contact area are critical. Advantage no holes.
