Q.

What kind of wind speed can solar panels withstand on roof installs?

A.

All solar installations in our area must be permitted, which means they must show the ability to withstand wind speeds of 90 mph.  This is the basic national standard, with higher requirements in  hurricane areas (125+ mph). It is actually the racking system attachment or the amount of ballast that is required to meet these standards. The panels will be fine.
