Welcome to the RV Solar Calculator! Our customer’s unique systems are important to us at Outside Supply.

Watts Used Per Hour X Hours of Days Used = Watts Used Per Day

Solar Watts Needed / Hours of Sunlight = Solar Wattage Needed 

For Example: 300 Watts Per Hour X 5 hours of RV use = 1500 Watts of RV Use Per Day

1500 Solar Watts Needed / 5 Hours of Sunlight = 300 Watts of Solar Needed

Simple wattage calculator for devices in your RV

To calculate the wattage of an item it is important to know both the amps and the volts that the item uses. This simple calculator will give you an easy conversion to watts.
