We have installed lots of pole mounted systems and we stay with what is recommended by the racking manufacturer.
I have witnessed several different top of pole solar arrays and solar-powered street lights that had been installed by others that were swaying 2 to 3 FEET at the top, and twisting almost 90 degrees of rotation during brief very gusty winds. Yes, these were tall poles which allowed more twisting and bending than a typical 8 to 10 foot hight pole, but I can guarantee you if these were made of cast iron they would have snapped off in minutes.
Its hard to believe just how far steel can twist and bend when supporting a large surface area in high winds without damage. I say you should tell your client to install a nice basketball net on his pole and then you should run as fast as you can and don't look back.
