When it comes to off-grid solar power for your campervan or motorhome, small 100W kits just don’t cut it anymore. A few lights and USB charging? Sure. But what about your 12V fridge, TV, water pump, laptops, internet and all those other electronic gubbins we forget about... TV projectors, fairy lights, even power-hungry “portable” packs like Jackery, EcoFlow or Bluetti, plus mobility scooters and e-bikes?

At Solar Shack, our 325W solar kit is the most popular choice. It gives you the freedom to run everything you need off-grid, without worrying about draining your leisure battery.

With solar, one rule always holds true:

Many online suppliers still promote 100W to 140W solar panels as “standard kits.” While they can trickle charge a leisure battery and run a few lights or USB sockets, they fall short for real-world van life.

It’s like the difference between your 2-hour fast phone charger at home and that painfully slow 8-hour USB charger at the airport. Small solar kits get the job done eventually, 

but why wait, when you could have all the power you need right now?

The 325W single-panel kit is the sweet spot for most van owners:

• Enough power for 12V fridge, lighting, TV, pumps, phones, laptops and internet.
   
• Single-panel design — no messy roof clutter, just one clean, high-output panel.
   
• Compact & efficient — fits neatly on most campervans and motorhomes.
   
• Futureproof — no need to upgrade later.
   

Installed price: £748 including MPPT controller (Victron or Epever, your choice).

A solar kit is only as good as its charge controller:

• Victron SmartSolar MPPT – premium brand, Bluetooth monitoring, exceptional reliability.
   
• Epever 30A MPPT + Display – solid, proven performance with an easy-to-read display.
   

At Solar Shack, both controllers are just £99, no hidden “premium upgrade” fees.

For those with high power demands (larger motorhomes, compressor fridges, laptops, electric scooters), we also fit:

• 390W single-panel kit (Victron or Epever MPPT) – ideal for extended off-grid trips.
   
• 450W single-panel kit (Victron or Epever MPPT) – maximum power from a single panel.
   

For most UK campervan and motorhome owners, the 325W MPPT kit is the best balance of cost, power, and practicality:

• Stronger than 100W–185W “starter kits.”
   
• Cheaper and simpler than multi-panel setups.
   
• Fully fitted for just £748 at our North East workshop (Ashington, near Newcastle upon Tyne).
   

If you’re asking “what is the best solar kit for my camper or motorhome?”... this is it.

Yes, but only if you go big enough. A 100W solar panel will struggle to keep up, but our 325W solar kit provides more than enough power to run a 12V compressor fridge, along with lighting, pumps, TV and chargers.

Most installs take around 4–6 hours at our Ashington workshop. We use high-end fast-curing adhesives, so your camper or motorhome is ready to go the same day.

Both are excellent MPPT charge controllers.

• Victron SmartSolar offers Bluetooth monitoring and premium build quality.
   
• Epever is a solid, proven option with a digital display.
  At Solar Shack, both are £99, so you can choose freely.
   

For most UK van owners, the 325W single-panel kit is the perfect balance of cost, power and roof space. It’s stronger than 100W–140W starter kits, yet more affordable and compact than multi-panel setups.

At Solar Shack, our 325W fitted kit costs £748 including controller (Victron or Epever). Larger options, like 390W or 450W kits, are also available for extended off-grid power.
