Over at the Wind-Sun Forums they almost launched a posse after me when I told them I was going to drill the frame in different places than the original locations. All kinds of doom and troubles were forecast. Of course, I went ahead and drilled. I have added aluminum angle pieces along he sides of the original frame.
An easy recovery from a misplaced hole is to fill it with bolt and nut. It should make it stronger in that location.
I used three aluminum channels to support the tilt struts, you probably don't have the luxury of that material in Mexico. Using a full length piece of material will be stronger than just drilling a mount bracket into the roof, though. The torque of the wind affected module will be spread along the length of the strut bracket.
