Solar blankets offer the perfect balance of portability and power for caravanners who need flexible charging options. Unlike fixed panels, you can position them for optimal sun exposure while keeping your van in the shade, and pack them away when travelling through scrub or low branches.
The solar blanket market has evolved rapidly, with new technology delivering impressive power outputs from lightweight, foldable panels. We’ve tested the leading models to find which deliver the best performance, durability and value for Big Lap travellers.
What to Look For in a Solar Blanket
Solar blankets vary significantly in power output, build quality and features. Here’s what separates the premium models from budget options that’ll leave you frustrated:
- Power Output: Look for 200W minimum for meaningful charging. 240W+ handles most caravan needs, while 400W suits heavy power users with large battery banks.
- Cell Type: Monocrystalline cells deliver better efficiency and low light performance than polycrystalline. Avoid amorphous panels for permanent setups.
- Build Quality: Canvas backing with reinforced corners and quality zippers. Cheap blankets fail at stress points within months of regular use.
- Cable Length: 5 to 8 metres minimum to position panels away from your van. Short cables force compromised positioning.
- Weather Resistance: IP65 rating minimum for junction boxes. Look for corrosion resistant connectors and weatherproof cable entry points.
- Included Controller: MPPT controllers extract 20 to 30% more power than PWM. Some blankets include quality controllers, others force you to buy separately.
- Warranty Length: 2+ years minimum. Solar panel technology is mature, so short warranties suggest cost cutting on components.
Test your blanket’s folding mechanism before your first big trip. Stiff canvas or awkward fold patterns become frustrating when you’re setting up daily.

Position your solar blanket facing true north (not magnetic north) and adjust the angle throughout the day for maximum output. A 30 to 45 degree angle typically works best in most Australian locations.
