Yes, solar panels can exceed their rated wattage. Think about their environment. Have you ever been driving and experienced temporarily blindness by a reflection from a highly polished surface like an oncoming windshield or a stainless steel trailer panel? The same thing happens to a solar panel. Hopefully your charge controller acts quickly enough to prevent electrical system damage.
Parking near a high rise building clad in reflective glass positioned . . . . just right . . . . can be brutal.
