To accurately determine the power requirements of your RV, the first step is to make a comprehensive list of all the electrical appliances and devices you plan to use. This includes everything from lights, furnaces, TVs, water pumps, slides, and any other appliances or devices that will require electricity.

Once you have a list of appliances, you need to determine the wattage required to run each appliance or device. You can usually find this information in the owner’s manual or on the device itself.

Next, estimate the number of hours you plan to use each appliance or device per day. This step is crucial in determining how much power you will need to generate every day.

For instance, if your refrigerator requires 120 watts to operate, and you plan to use it for 8 hours per day, you will need to generate at least 960 watts daily (120 watts x 8 hours).

After calculating the total wattage for all your appliances and devices, you can use this information to determine the size of the solar system required to generate enough power to meet your needs. However, it’s recommended to add some extra capacity to your solar system to account for cloudy days or any other factors that might impact the efficiency of your solar panels.
