How many solar panels do you need for an RV?

The number of solar panels required for an RV depends largely on the following factors:

daytime peak hours

Peak sunshine hours are the most important aspect of determining the number of solar panels you need.

GHI (peak solar hours) is the amount of solar irradiance hitting the Earth's surface taking into account different weather conditions. Every country in the world has different peak sunshine hours, and without this information, it's impossible to calculate how many solar panels you need for your RV.


energy consumption

Find out how much electricity your RV solar system size consumes and determine how much solar energy you need to generate to keep your RV equipment running smoothly.

On average, an RV will use between 4 and 15 kWh per day. This is approximately 124 – 465 kWh per month or 1,488 – 5,580 kWh per year. All the devices used in the RV, their power and how long each device has been used. A table as shown in the table below,
