I = current (amps)
V = Voltage
mp = Maximum Power.
oc = Open Circuit
sc = Short Circuit
You really want to watch Isc or maximum short circuit amps so you get the proper rated controller.
Generally Imp x Vmp = panel rating in watts.
1.16 & 17.4 seems like a 20w panel not 90w.
Basically you are buying amps. The I (amps) is what you will get into the battery. The controller basically clips voltage down to what is needed to properly charge and maintain the battery.
