Why bother with roof-top solar?
Rolling into a pitch only to discover the hook-up sockets are full—or worse, paying £5 a night just to keep the lights on—gets old fast. A dedicated solar array means your 12 V leisure battery stays topped up while you wild-camp at the beach or run that laptop for one more Netflix binge. No more idling the engine, no more frantic campsite hunts.☀️

Installation & Mounting Tips
- Rigid panels → Z-brackets + Sikaflex 252
Clean, key and degrease the roof, then bed each bracket into a 5 mm bead of polyurethane adhesive and run four stainless M6 bolts. Sikaflex bonds like epoxy but remains slightly elastic for vibration —stronger than VHB tape on uneven GRP roofs. DIY Solar Power Forum Wild Camping for Motorhomes - Flexible panels → VHB tape perimeter + vent gap
Flexible laminates can “print” heat onto the roof if stuck flat. Leave a 10 mm bead-line round the edge only; this forms a spacer so air can wash underneath and keep temps < 80 °C. FacebookVW T4 Forum - Think tilt for winter
A simple hinge-and-prop kit lets you lift the south-facing edge by 40–50 °. Expect up to 25 % more yield on short December days—just remember to drop it before driving! Mowgli AdventuresMotorhomeFun - Cable glands & fusing
Use a double M20 IP68 gland, 4 mm² UV-resistant cable and a 20 A inline MIDI fuse within 150 mm of the battery. That keeps you onside with BS 7671 and NEC 690 guidelines. The Van Conversion
How We Chose
We cross-checked Amazon UK’s top-rated camper-solar kits (≥ 4 ★ & 50 reviews), filtered out plastic-framed cheapies prone to hotspots, and weighed output per pound. Hands-on testing with a 40 L compressor fridge and laptop charger confirmed the wattage claims. Pricing shown is Amazon UK list on 19 Jul 2025 and may fluctuate.
Frequently-Asked (Quick-Fire)
- PWM vs MPPT? —MPPT squeezes 10-30 % more amps in British shoulder seasons; worth the extra £50 if you’re touring spring/autumn.
- Can I mix panel brands? —Yes if the voltage & current match within 10 %; otherwise the lower spec drags the array down.
- Drilling horrors? —Stick-on options exist, but a proper cable gland with butyl tape is a 15-minute job and won’t void most van roof warranties.
