A solar blanket suits campers who want light weight and a small pack size. A hard frame panel suits those who want maximum durability and a panel they can mount or prop up at camp. A flexible panel suits a low profile, set and forget setup on a canopy or roof. For most weekend trips, the right pick comes down to what you can carry, how you will position the panel at camp, and how many watts your fridge and devices draw over two or three nights.
What to look for in camping solar panels
Before comparing formats, get clear on the basics.
Heat changes the numbers
Australian heat, red dust and UV are tough on gear. Panels are rated at a 25°C cell temperature, and output drops as they heat up, which happens all the time in an outback summer. It is worth sizing slightly above your bare minimum and choosing a brand with local warranty support.
Solar blankets vs hard frame panels vs flexible panels
Solar blankets
Best when boot space is the limit
Solar blankets are the go to folding solar panels for camping. Their lightweight fabric design folds flat into a slim bag, which is ideal when the boot is already full. A foldout stand lets you angle the cells toward the sun.
Hard frame panels
Best for charging while you drive
Hard frame panels are the toughest option. They are usually mounted on a roof or canopy so they charge while you drive, and they can also be propped up at camp. They are heavier and do not pack down.
Flexible panels
Best for curved roofs and canopies
Flexible panels are just 3mm thin and bend to fit a canopy, bonnet or curved roof, at less than half the weight of a hard frame panel. Because they sit flat with no air gap, they can run hotter and lose some output.

The big advantage of a portable blanket is that you can park in the shade while the panel sits in full sun.
What wattage do you need for a 2 night trip
Work it out before you leave instead of guessing at camp.
Worked example
A setup using 600Wh a day with 4 sun hours needs around 150W. Add a 25% buffer and you are in the 200W class. Over two nights you will use around 1,200Wh, so a 100Ah lithium battery gives you a day's reserve if the weather turns. If you are only charging phones and a head torch, a 20 to 50W panel will do.
Where a 400W solar blanket fits
A 400W blanket suits campers running a fridge and several devices off a larger lithium battery bank. It is overkill for a weekend of charging phones.
Do not expect a steady 400W. On a clear day, portable panels generally deliver around 75 to 85% of their rated output, so treat the rated figure as a best case ceiling. Always check your power station's maximum solar input before buying a panel this size.
Setting up at camp
Never wire a panel straight to a battery
Always use a charge controller. MPPT is the better choice for anything over 100W, delivering up to 20 to 30% more usable power than PWM.
Check compatibility
Match voltage, current and connector type (MC4, Anderson, XT60) to your power station or DC-DC charger.
Connect first, unfold second
Plug in while the panel is still folded, then angle it to the sun.
Reposition through the day
A panel nudged toward the sun a few times a day will beat the same panel left flat from breakfast to dinner.
Choosing the right panel for your camping style
Hikers
A light 20 to 100W panel for phones, GPS and power banks, like the 650g 20W Solar Blanket Compact.
Weekend car campers
A 200W solar blanket, light enough to carry and big enough to keep a fridge and devices topped up.
Caravan and off grid tourers
300W or more, with an MPPT controller and a correctly rated battery. Many pair a mounted hard frame or flexible panel with a portable blanket.
When two panels look similar on paper, Australian backed warranty and support is a smart tie breaker. Compare iTechworld's solar blankets, hard frame panels and flexible panels against the sizing above before you commit to a wattage.
Quick FAQs
How many watts of solar do I need for a camping fridge
A typical 40 to 60L compressor fridge uses around 18Ah a day. Aim to generate 25 to 30Ah for some margin.
What size solar panel do I need to charge a caravan battery
A 100Ah bank can usually be maintained with a 100 to 200W panel. Larger 200 to 300Ah banks need a bigger panel or multi panel array. Remote tourers often carry a generator or spare power station for long overcast stretches.
How long does it take to charge a battery with a solar panel
Divide your battery's Wh by the panel's realistic output. Angle, cloud and shade all change the result, so treat it as an estimate.
Can portable solar panels get wet
Most are splash and rain resistant, not waterproof. iTechworld's solar blankets are IP rated for splash resistance, while its hard frame and flexible panels are IP67. Dry the connectors before reconnecting, and disconnect before a heavy storm.
