It may seem obvious but all of these factors will effect how much power your 100 watt solar panel can bring in.
Solar panel for fridge lights and tv.
Inverter if you have an inverter it will need to handle about twice as much as the maximum load so a 2 200w inverter should work for this example.
The solar panels will charge the battery and keep it ready to supply power to your fridge.
The fridge has a standard run time of 24 hours and the tv and lights 5 hours.
The coach and chassis electrical systems on our coach are completely separate.
I want to use an inverter in the kitchen for the microwave and anything else that would run on 110 as point of use inverter turned on only when needed to run it.
It will be fully charged the next day.

We currently have 300 watts of solar panels on the roof.
These are run through the factory installed combiner and are integrated through a 40 amp solar charge controller from zamp.
This is a real life example of someone who has been using the exact solar power kit i recommend here on this site.
I will be running the whole house on 12v cellphone laptop fridge lights tv projector.
We started off with one 100 watt panel.
A device called a charge controller will smooth the flow of power from the panels to the battery.
It is this that makes the answer to the question not all that straightforward.
Here are a couple panels that would be good options though with varying wattage levels.
Batteries are needed to store the power that the refrigerator will use at night or when clouds block the sun.
A bit of quick math and conversion to kwh will tell us that each solar panel produces about 30 kwh per month.
The solar kit comes with the following.
Solar kit to run tv laptop fridge mobile or lights worst case scenario.
Divide that by 30 kwh per month per solar panel and you get 3 8 solar panels.
3 140 watt solar panels 4 65ah batteries 1 30a pwm regulator 6 led lights 1 19 flatscreen led tv.
If we assume a 5 5 x 3 foot solar panel 200 to 250 watts would generate about 0 75 kwh per day it would take three of those panels to power a fridge that uses 46 wkh per month.
The average refrigerator found in the united states uses approximately 57 kwh per month while the average freezer uses 58 kwh for a combined total of 115 kwh.
You work backward from the panels you ve got.
A solar power setup suitable for refrigerator use requires several devices in addition to solar panels.
