Sure the amph is just the storage capacity. If you use a higher storage capacity it just means you can store more energy.
To do a proper caculation you have to know what the amperage of the gate motor is. The amperage of the load is what governs the size of the wire. There are two ways to power a Gate opener DC OR AC. Smaller units and residential units are generally DC. Larger commercial are usually AC or use a combination of DC and AC technologies. I will assume it is a DC operator being powered off a battery, with the solar panel maintaining the battery. As for the solar panel the panel was probably a 5 watt not a 5 amp, as a 5 watt panel is generally the smallest panel you would want to use to supply power to a gate operator. This supplies a trickle of power at 12V which charges a 12V battery. These panels generally charge at or less than 500 milliamps.Generally #16 would be fine for such a length.
Left front faring panel, small compartment panel within this panel. Battery lays on it side in this compartment.
Tn On Garage Door Opener
The battery is located behind the LEFT plastic panel that says SHADOW. The panel is below the seat.

There is a panel (held on with 4 screws) on the floor between where your feet rest. The battery is under the panel.
Normally its several screws on bottom panel and in the handles and surclip on the window winder handle if they have them. Then the whole panel should pull of and lift up over door opener
It' the fuse for your Instrument Panel Battery
The fiberglass panel at the side of the battery has to be removed and the battery is removed sideways.
Put the solar panel in the sun;Attach the red wire of the panel to the positive terminal of the battery;Attach the black wire of the panel to the negative terminal.
The fiberglass panel at the side of the battery has to be removed and the battery is removed sideways. I wouldn't remove the panel entirely,I would remove the top bolts on the side panel and remove the ones on the fender weld. At the bottom of the side panel where the gap is,I would just loosen it so the panel can fall outwards, this will allow you to work the battery outwards, may have to tip it to get out and tip it again to get it back in.
The battery on a Ferrari F430 is located in the front trunk compartment, underneath the carpeted panel on the passenger side. You can access it by removing the panel and then disconnecting the terminals to replace the battery.
