Checking truckfridge.com average usage on their basic 12v compressor unit is 2 amps/hr that's 48 amp hours a day. Under the best sun conditions, no clouds, no trees, panels perfectly aligned to the sun, the Go Power! GP-PSK-120 would only produce 53.6 amp hours of replacement energy with 8 hours of sunlight, at 6.7 amps output (data per the Amazon page). That would be cutting it pretty close even if you had no other loads.
Before you go looking for solar panels determine what your expected daily amp hour load is, then you can make a better decision on panel and battery requirements.
