I looked up the hours of sun and somewhere I read I have the equivalent to 4-5 hours of sun a day.
So, if I use 175 watts per hour for my refrigeration, that is 4.2kW/day.
So to supply that much power (or more), and assuming I get about 4 hours of usable sun a day, I need about 1000 watts? Is that right?
Am I anywhere close to calculating this correctly?

Your calculations are off, if your refrigeration is consuming about 135w each (aprox) that would be for three fridges, around 400w @ 3-5 minutes per hour , on average.
You need to find the yearly consumption of your fridge / freezers then size a solar system to support it, according to the needed sunlight hours.
