If you will list specs of your controller, such as is it 12/24v, 20 amp, MPPT or just PWM type. If you'll list specs I think I can help, but to start with, a single panel rated 100w is not enough for an 80w pump unless you are wiring it direct to pump (DC) but your pump is AC so you can't do that.
If your setup is 12v you have to be very careful about wire size, 24v-not so much.
It's not too bad figuring all of this out, we just need some info on your controller.
