I hope I'm expert enough to qualify!

Upon first glance it appears your controller will allow 24v input.

What's important now is to determine if the controller's amperage rating divides in half for 24v input. It probably does, meaning that at 24v your controller's max is 15/2 or 7a. You could see 10 on a good day.

At least that's what I'd be questioning.

MPPT controllers take the input voltage and current and convert it to the output voltage and current. He can possibly get 17A output, but not likely. But since this panel exceeds the controllers limit caution is the name of the game.
