Solar panel Amp rating vs Charge Controller Amp rating

Hi All,
I'm in the process of swapping out an old single solar panel on my roof with two bigger panels: 140W rated at 8amps.

The van currently has an older SCI PWM Charge Controller rated at 15Amps.

Will I need to get a new charge controller to? or is this close enough that I can get by without having to replace the controller?

I'd switch just to get the extra power from a mppt. I actually did that two years ago. But I'd up the unit to safely handle the power difference.
