This can depend on the size of the fridge itself.
What solar panel do i need for camping.
Flexible solar panels have an amazing advantage on curved surfaces where traditional modules would represent problems due to the fixed mounting structure.
Why do i need a regulator.
How many solar panels do i need to run a fridge.
The general rule of thumb is that a 100 watt solar panel can produce about 30 amp hours per day so you can use this guideline to determine about how many panels you need.
A 100 watt solar panel produces approximately 6 amps per hour in direct summer sun without clouds.
By using the battery your fridge keeps running even if the voltage output of the solar panel drops severely due to cloud cover.
For our experiment 5 hours of direct sunlight without clouds x 6 amps generated per hour 30 amp hours per day that the solar panels are generating to.
Tips for estimating rv solar panel needs although actual output may vary based on the factors mentioned above you can get yourself to a ballpark figure using a couple of tips.
What the sun will provide.
Assuming we get 5 hours of direct sunlight we know a 100 watt solar panel will produce 30 amp hours per day.
The renogy 50 watt flexible monocrystalline solar panel is an excellent choice for boats rv or camping purposes.
On average a system that consists of two one hundred and twenty volt panels should provide more than enough power to run a small rv fridge.
A 12v battery needs at least 13 6 volts to charge therefore under worst case conditions a solar panel needs to output at least 13 6 volts.
