Thinking about going off-grid with your caravan in the UK? A solar panel kit is one of the smartest upgrades you can make. Whether you’re wild camping in the Highlands or parked up in the Lake District, a good solar kit keeps your leisure battery topped up—no mains hookup needed.
In this guide, we’ll walk you through the best caravan solar panel kits in the UK, what to look for, and how to choose the right one based on your travel style, power needs, and setup space.
Why You Need a Solar Panel Kit for Your Caravan
A solar panel kit provides clean, quiet, and free energy wherever you park.
If you’ve ever had a flat leisure battery or been stuck without power at a remote campsite, you know how frustrating it can be. A solar kit changes all that by:
-
Charging your leisure battery daily
-
Powering lights, water pumps, TVs, laptops, and more
-
Supporting off-grid stays and wild camping
-
Reducing reliance on generators or hookups
It’s the ultimate freedom tool for modern caravaners.

What to Look for in a Caravan Solar Panel Kit (UK Edition)
Before you buy, here’s a quick checklist of what to consider:
| Feature | What to Look For | Why It Matters |
|---|---|---|
| Panel Type | Monocrystalline or polycrystalline | Mono offers higher efficiency, especially in low light |
| Wattage | 80W – 200W | Choose based on your daily power needs |
| Controller | PWM or MPPT | MPPT is more efficient, especially in cloudy UK weather |
| Mounting Type | Fixed, portable, or flexible | Pick based on your roof setup and installation preference |
| Cables & Connectors | Prewired kits save time | Ensure compatibility with your leisure battery |
| Build Quality | Weatherproof and UV-resistant | UK weather can be harsh, especially in winter |
How Much Solar Power Does Your Caravan Need?
Here’s a rough guide based on daily usage:
| Power Usage | Suggested Wattage | Typical Setup |
|---|---|---|
| Light use (lights, phone charging) | 80W–100W | 1 leisure battery |
| Moderate use (lights, pump, laptop) | 120W–160W | 1–2 batteries |
| Heavy use (TV, fridge, inverter) | 180W–250W+ | 2+ batteries or MPPT system |
Pro Tip: Use a power audit to calculate your exact needs. Tally up all your devices and how long you use them daily. Add a 20–30% buffer to account for cloudy days.
Installation Tips for Caravan Solar Kits
-
Always seal roof mounts with waterproof sealant
-
Angle your panels if possible—even a 10° tilt improves winter performance
-
Install the controller close to the battery
-
Use MC4 connectors for secure, waterproof connections
-
Label your wiring and test everything before final installation
If you’re not confident with 12V electrics, it’s worth hiring a professional installer—especially for permanent roof-mounted kits.
