I think you'll find that you would need a very large solar panel and equally large bank of batteries to run a fridge 24 hours.
The majority of people opt for running fridge on gas when off grid.......as I do.
I use a 60W folding panel which can be positioned to collect the sun's rays effectively.
I can easily go for 7 days powering led lights, water pump, charging phones and tablets and a bit of TV via a 300W invertor. Still enough left in the leisure battery to use the motor mover to get off the pitch.
