In this article, we’ll explore the factors to consider when choosing a solar panel for your caravan, and provide some tips for selecting the perfect panel for your needs.
Understanding Your Energy Needs
Before you can choose the right watt solar panel for your caravan, you need to understand how much energy you’ll be using. This will depend on a number of factors, including the size of your caravan, the number of people using it, and the types of appliances you’ll be running.
Some common appliances used in caravans include:
- Lights
- Refrigerators
- TVs
- Computers
- Mobile phone chargers
Each of these appliances will have a different power rating, measured in watts (W). To calculate your total energy needs, you’ll need to add up the power ratings of all the appliances you’ll be using.
For example, let’s say you have a caravan with the following appliances:
- 2 x 10W lights
- 1 x 50W refrigerator
- 1 x 20W TV
- 1 x 10W computer
- 1 x 5W mobile phone charger
Your total energy needs would be:
2 x 10W = 20W (lights)
+ 50W (refrigerator)
+ 20W (TV)
+ 10W (computer)
+ 5W (mobile phone charger)
= 105W
Calculating Your Daily Energy Needs
Once you have a total power rating for all your appliances, you’ll need to calculate your daily energy needs. This will depend on how many hours a day you’ll be using each appliance.
For example, let’s say you’ll be using your lights for 8 hours a day, your refrigerator for 24 hours a day, your TV for 4 hours a day, your computer for 2 hours a day, and your mobile phone charger for 1 hour a day.
Your daily energy needs would be:
- Lights: 20W x 8h = 160Wh
- Refrigerator: 50W x 24h = 1200Wh
- TV: 20W x 4h = 80Wh
- Computer: 10W x 2h = 20Wh
- Mobile phone charger: 5W x 1h = 5Wh
Total daily energy needs: 160Wh + 1200Wh + 80Wh + 20Wh + 5Wh = 1465Wh
Choosing the Right Watt Solar Panel
Now that you have an idea of your daily energy needs, you can start thinking about the right watt solar panel for your caravan. The size of the panel you’ll need will depend on a number of factors, including:

- The amount of sunlight your caravan will be exposed to
- The efficiency of the solar panel
As a general rule, it’s a good idea to oversize your solar panel by 10-20% to account for any unexpected energy needs or periods of low sunlight.
Based on our previous example, let’s say you need a solar panel that can generate at least 1465Wh of energy per day. To calculate the size of the panel you’ll need, you can use the following formula:
Solar panel size (W) = Total daily energy needs (Wh) / Peak sun hours (h)
Peak sun hours refer to the amount of time the sun is shining at its strongest. This will vary depending on your location and the time of year.
For example, let’s say you’re traveling in an area that gets an average of 5 peak sun hours per day. To calculate the size of the solar panel you’ll need, you can plug in the numbers as follows:
Solar panel size (W) = 1465Wh / 5h
= 293W
So, in this example, you would need a solar panel with a minimum rating of 293W. However, to account for any unexpected energy needs or periods of low sunlight, you may want to consider a panel with a higher rating, such as 300-350W.
