If you want more freedom when touring in 2026, a caravan solar panel is one of the most effective upgrades you can make. It allows you to generate your own power, extend off-grid stays, and reduce reliance on campsite hook-ups.
In this guide, we break down what to look for in a solar setup and how to choose the right panel based on your power usage, caravan size and travel style.
Why Add Solar Panels to Your Caravan?
Solar panels convert daylight into usable power, charging your leisure battery throughout the day. This helps keep your lights, fridge, devices and other equipment running without needing constant access to mains electricity.
For UK touring, where you may not always rely on consistent sunshine, choosing the right system size and battery setup is key.
What Size Solar Panel Do You Need?
The size of your solar panel depends on how much power you use daily.
-
50W to 100W: Suitable for light use such as lighting and phone charging
-
100W to 150W: Ideal for regular touring with moderate appliance use
-
150W to 200W+: Best for off-grid setups with fridges, TVs and extended stays
If you are running higher demand systems, your solar setup needs to be paired with the right battery capacity.

Rigid vs Flexible Solar Panels
There are two main types of caravan solar panels.
Rigid panels:
More durable and typically more efficient. Best suited for permanent roof installations.
Flexible panels:
Lightweight and easier to install on curved roofs. Ideal for campervans or temporary setups.
Can Solar Panels Power a 12V Air Conditioner?
This is one of the most common questions from caravan owners.
Solar panels alone will not directly power a 12V air conditioner. However, they can recharge your leisure battery, which then supplies power to your system.
For cooling setups, you need a combination of:
- High-capacity lithium battery
- Adequate solar input
- Efficient power usage

- Leisure battery
- Charge controller
- Power management system

Final Thoughts
Solar panels are one of the best upgrades for caravan and motorhome users looking to extend their time off-grid.
For light users, a smaller panel may be enough to maintain battery charge. For regular touring or longer trips, a larger setup combined with a lithium battery will give you the most flexibility.
