the big panel the better? volt vs Amps
"pulled" down to the battery voltage, about 15V (for a 12V battery) This is true for a 18V panel, or a 45V panel, hook both to a battery, and they both would read the voltage. It''s pretty certain the 18V panel will charge the battery faster, because it is delivering it''s watts very close to it''s power curve.

How to reduce solar panel VOC (Important!)
For example, if your solar controller has a maximum voltage of 150 volts, and each of your solar panels produces 36 volts, and you string five panels into a string, you get 180 volts. The answer is to string fewer panels; in this example, strings of three panels are ideal. If you need to string five 36volt panels together, you need a controller ...

Solar Charge Controller Sizing and How to Choose One
Solar panels output more than their nominal voltage. For example, a 12v solar panel might put out up to 19 volts. While a 12v battery can take up to 14 or 15 volts when charging, 19 volts is simply too much and could lead to damage from overcharging. Solar charge controllers aren''t an optional component that delivers increased efficiency.
