1. Choosing Mounted or Portable Solar Panels for your Caravan, Camper or RV

Solar panels come in two categories - mounted or portable – with both options having advantages and disadvantages. The main difference between mounted solar and portable solar panels is that portable panels allow you to chase the sun whereas a caravan with panels mounted on the roof often needs to park in the sun to receive enough sunlight. For more information, you can have a look at our previous blog post about Choosing a Portable 12V Solar Panel for Camping

2. Solar Power requires Solar Batteries - Caravan Solar Panels and Battery Setup

To store the energy generated by your solar panels, it is important to have batteries that are large and sturdy enough to do so. Solar batteries are designed to do just that. They are not disturbed by frequent charging and discharging, require very little maintenance, and have a high cyclic life. Generally, solar systems for caravans use AGM deep cycle batteries. Larger systems used for off grid living, require larger tubular gel batteries.

The size of your solar batteries is important and depends on several factors, such as the length of your trip, how much power autonomy you want, and how many appliances you want to use at once. To find out which battery size you need to run your gear, you can have a look at our battery guide here. Or Check out our great range of  solar kits for caravans and camping.

3. Running 240V appliances with Solar Power - Getting the Best RV & Caravan Solar Panel Setup

There are several ways to power your appliances when you’re camping or caravanning, but solar power is becoming increasingly popular. Solar panels generate more than 12V and will need a solar regulator to ensure your deep cycle batteries won’t overcharge and get damaged. From the batteries, you can then run any 12V item. Most appliances though need 240V, such as fridges and TVs. In this case, you will need an inverter to safely convert the 12V power to 240V power.

4. Be prepared for bad weather conditions and emergencies

Best Solar Panels for Camping, Caravans, Motorhomes and Recreational VehiclesIf there is one thing you cannot control while you’re on a holiday it’s the weather. When weather conditions are bad for an extended time, your solar panels may not be able to generate enough power. As such, it’s best to always have a backup plan prepared. Generators can do the trick, or you can set up a dual battery system with a DC charger. Standard dual battery systems exist of two batteries (your vehicle’s battery and a secondary battery), but they can have as many batteries as you want – within reason, of course. Adding a DC charger to this system will allow you to charge your secondary battery back up to full which increases its battery life. This device also boosts the voltage going to the auxiliary battery, so no voltage loss occurs. Read our ‘Beginner’s Guide to Vehicle Chargers’ for more information on dual battery systems and DC chargers.

Alternatively, if you prefer to keep using solar power, you can also add solar panels to your caravan setup or replace your smaller portable solar panel with a larger one.

5. Ensure you don’t run out of power - Get the Best Solar Setup for Caravans or Camping

Before you leave on your camping trip, consider how long you want to be away from mains power. The longer you want to stay off grid, the larger your solar system needs to be. As such, it’s important to take enough batteries, or the right size of battery, to ensure you have enough power to last through your trip. Estimating the right size of battery for your setup is as simple as a four step calculation:

1) Estimate the running time of each camping appliance you wish to use over a time of one day.

2) Multiply the wattage of each camping item by its estimated running time.

3) Add the watt hours for each device together to reach an estimate of your total power consumption.

4) Convert the total watt hours to amp hours and discover which battery size you need.

Once you know this, you can double the battery size to consider a 50% depth of discharge. During camping trips where you don’t have the option to re-charge your battery, it is best to time the battery size by the number of days your camping trip will last.
