How to Choose the Best Solar Blanket for Camping & Touring Australia

Are you looking for the best solar blanket in Australia? There are many factors to consider when purchasing one. Our guide will give you a comprehensive overview of how the best solar panel blanket work what they can do and the best ones on the market.

Solar blanket technology has progressed over the years, and now there are a ton of different options for caravanners and campers who want to be totally off-grid while on their adventures. It’s always important to consider your own needs before choosing which panels work best for you, some will best suit your needs, and some won’t.

Most of these panels work best for that extra boost when caravanning and reliable power is one of the key considerations when planning a Big Lap or driving around Australia long-term. You may be parked up in the shade, have endless cloudy days (we hope not!) or simply not have enough solar on your roof. Even though we have 4 x 210w solar panels on our van’s roof we will still carry a solar blanket for those days when the sun doesn’t want to come out and play.

A solar blanket generates DC electricity from sunlight. In most caravan and camping setups, that solar power is fed through a compatible solar regulator, DC-DC charger or portable power station, which then uses it to charge a battery.

Your fridge, lights, pumps and other 12V gear normally run from the battery rather than directly from the solar blanket. Think of the blanket as another way of putting energy back into your battery system while you’re camped.

How long you can stay off-grid has very little to do with whether you are away for two days or two weeks. It comes down to the balance between how much energy you use and how much you can put back into your batteries.

A solar blanket might be enough to keep a modest setup going indefinitely in good conditions, or it might barely make a dent in a power-hungry setup running large inverters and appliances.

Battery capacity, total solar input, weather and your daily power use all matter.

Solar blanket technology is improving every year, so it’s best to keep a close eye on the best solar blanket for camping has to offer.

Not every popular solar blanket is included here. We prioritise models we trust, and can actively support with up-to-date pricing and availability for Aussie caravanners and campers.

When A Solar Blanket Actually Makes Sense

Solar blankets are a top-up, not a full power system

For most caravanners, a solar blanket works best as flexible additional solar rather than being chosen in isolation.

Some simple camping setups can run entirely from portable solar, but long-term caravanners usually have fixed solar or vehicle charging as their base and use a blanket when they need extra input or when the roof is shaded.

Why roof solar plus a blanket is common for long-term touring

Most long-term caravanners rely on fixed roof solar as their base, then use a blanket to boost charging when needed. This combo gives you flexibility without permanently adding more weight or panels to the roof. It’s one of the most common setups we see among full-time lappers.

Why shade matters when travelling Australia

Shade is great for keeping your van cool, but it’s terrible for roof solar. In hot parts of Australia, you’ll often choose shade over sun to stay comfortable. A solar blanket lets you park in the shade and still chase the sun by placing the panel out in the open.

Why solar blankets suit caravanners who move camps

If you move regularly, a solar blanket makes sense. You can pull it out, plug it in, and pack it away quickly without committing to permanent changes. It’s especially handy for short stays, overnight stops, or topping up batteries between longer drives.

Camping Solar Blanket Vs Camping Solar Panels

Most big lappers use fixed roof solar as their base system and a solar blanket as backup when conditions aren’t ideal.

Choosing between portable solar panels vs portable solar blankets comes down to how often you travel:

If it’s weekly or monthly, then use either depending on which will save money, of course, the weight will always be a consideration.

If you are touring Australia and doing the Big Lap then you’ll definitely be looking for the lightest and easiest setup option.

If you’re a weekend camper, portable solar panels are the best option. They’re less expensive and give you flexibility in where to move them while still giving off enough power for your needs. Plus they work well if all of your necessities fit inside one bag! The downside is that these panels can be bulky and heavy but only an issue when carrying more than just what’s necessary with you when you camp.

When it comes to campers, solar blankets really are the best option as you don’t want something bulky or too expensive on your roof rack. The great thing about these is they’re lightweight and easy to store when it’s not in use.

With the rise in popularity of nomads and full-time caravanners, many people are opting to invest in a solar panel system. Fixed panels can be cost-effective for those who plan on staying put, but they lack flexibility as you will need to park your vehicle near direct sunlight so that it is charging at all times. Portable solar panels for camping might be best for your situation and needs.

However, these panels have other benefits such as being easily set up (no equipment required) and simple to use. If this doesn’t suit you then maybe an option would be fixed with portable solar blankets or extra panels when needed as mentioned above.

How To Choose The Best Folding Solar Blanket 

Types

As you can see in the above comparison chart, many different types of solar blankets for camping are on the market today. Each blanket uses a form of solar technology known as photovoltaic cells (PV).

A solar blanket typically comprises of many photovoltaic cells, best known as solar panels, which convert the sun’s energy into electricity for powering devices such as batteries and camping fridges.

What Type of Solar Blanket Should You Choose?

Most of the solar blankets we now recommend use monocrystalline cells. They provide a good balance of efficiency, size and weight, which is particularly useful when storage space and payload matter in a caravan or 4WD.

You may also see newer cell technologies such as PERC, N-type and TOPCon. These can improve efficiency, but I wouldn’t choose a solar blanket based on the cell name alone.

For caravanning and camping, I’d look at the complete package:

• Rated wattage
• Weight and packed size
• Open-circuit voltage (Voc)
• Connectors
• Whether a regulator is included
• What type of regulator it is
• Battery compatibility
• Weather resistance
• Warranty
• How easy it is to position towards the sun

The most efficient panel on paper is not necessarily the best one for your setup if it is too heavy, difficult to store or incompatible with your existing charging system.

Size

Solar blankets are much easier to transport and store than old hard-frame solar panels. They’re also more convenient for Lappers and campers because they take up less space in storage. They are less prone to breakage when accidentally dropped or struck with an object.

The glass-free cells allow them to resist accidental damage that would otherwise occur through impact, such as dropping or scraping against other objects. These solar blankets have many benefits compared to older versions: easy transportation/storage, durable construction (resistant even if it is bumped around), etc.

Weight

Solar blankets weigh less than half the weight of the older style solar panels, making them ideal for caravanning and camping. Depending on your blanket, they can weigh anywhere from a couple of kgs to a whopping 16kg.

Naturally, the best solar blanket is lightweight with great output.

Quality

Quality to look for when buying a solar blanket is the quality of the cells, as mentioned above. In addition, the quality of the material and the anti-reflective coating is also important.

Common Solar Blanket Mistakes

• Buying based only on advertised wattage
• Assuming a 200W blanket will constantly produce 200W
• Using a solar regulator that does not support your battery chemistry
• Running the blanket through its portable regulator when your DC-DC charger expects unregulated solar input
• Plugging solar into an Anderson connector without confirming what that connector actually feeds
• Exceeding the maximum solar input voltage of a DC-DC charger or portable power station
• Connecting two regulators in series without confirming the system supports it
• Assuming every solar blanket is waterproof
• Leaving the blanket flat or partly shaded and wondering why output is low
• Buying more solar without first knowing how much power you use each day

---

Solar Blanket Questions

How Do You Use a Solar Blanket While Camping?

First, work out where the solar input is going.

That might be:

• Your caravan’s solar regulator
• A DC-DC charger with a solar input
• A portable solar regulator connected to the battery
• A battery-management system
• A portable power station with a dedicated solar input

Then check that the solar blanket’s voltage, wattage, connectors and regulator arrangement are compatible with that system.

Once connected correctly, place the blanket in direct sunlight and aim it towards the sun. If it has adjustable legs, use them rather than leaving the blanket flat when the sun is lower in the sky.

Move the blanket during the day if practical. Even partial shade across part of a solar blanket can substantially reduce output.

If your caravan is parked under a tree, one of the biggest advantages of a portable blanket is being able to run a lead out into full sun while keeping the caravan itself in the shade.

Avoid connecting a solar blanket to random 12V sockets simply because the plug fits. Use the solar input specified by the manufacturer of your battery or charging system.

Will a 200W Solar Blanket Actually Produce 200 Watts?

Sometimes you may get close, but you shouldn’t build your power budget around seeing the advertised wattage continuously.

The wattage printed on a solar blanket is its rated output under standard test conditions.

Real-world output changes throughout the day because of:

• Sun angle
• Cloud
• Shade
• Panel temperature
• Dirt and dust
• Cable losses
• Regulator efficiency
• Battery state of charge
• How the blanket is positioned

A blanket lying flat in the morning may produce considerably less than the same blanket aimed directly at the midday sun.

Also remember that watts and daily energy are different things.

A 200W panel tells you its maximum rated power. What matters to your off-grid setup is how much energy it can put back into the battery over the whole day.

That is why I would size your solar system from your actual daily power use rather than simply deciding that “200W should be enough”.

Should I Run My Fridge Directly From a Solar Blanket?

Generally, no.

In a caravan or 4WD setup, your solar blanket is normally used to charge a battery through a compatible regulator or solar charger. Your fridge and other 12V equipment then run from that battery.

The battery acts as a buffer when a cloud passes over, the panel is shaded or solar production falls late in the afternoon.

Some portable power stations accept solar directly because the solar regulator is built into the power station. In that case, connect the solar blanket to the designated solar input and stay within the manufacturer’s voltage and current limits.

Don’t bypass the charging equipment or connect an unregulated blanket directly to a conventional battery unless the battery system is specifically designed for that connection.

PWM vs MPPT Solar Regulators: What’s the Difference?

A solar regulator controls the power coming from your solar blanket before it reaches the battery.

The two common types are PWM and MPPT.

A PWM regulator is the simpler and generally cheaper option. It effectively pulls the solar panel voltage down closer to the battery charging voltage. It can work perfectly well in a correctly matched smaller 12V setup.

An MPPT regulator is more sophisticated. It allows the solar panel to operate closer to its maximum power point and converts excess panel voltage into additional charging current. This can extract more usable power from the panel, particularly when panel voltage is well above battery voltage or conditions are less than ideal.

That doesn’t mean everyone needs to throw away a perfectly good PWM controller.

The bigger question is what regulator is already installed in your caravan or vehicle.

If you already have a DC-DC charger or battery-management system with an MPPT solar input, you may be better connecting the solar blanket directly to that solar input and bypassing the portable regulator supplied with the blanket.

Do not assume that connecting one regulator through another is correct. Check the instructions for your specific charging system first.

Will Any Solar Blanket Charge a Lithium Battery?

The solar blanket itself usually isn’t the deciding factor. The charging system between the blanket and the battery is.

If you have a lithium LiFePO4 battery, the solar regulator, DC-DC charger or battery-management system needs to have a suitable lithium charging profile.

Do not assume a regulator is lithium compatible just because it has an Anderson plug or came packaged with a solar blanket.

Some controllers can be configured for different battery chemistries, while others cannot.

Before connecting a new solar blanket, check:

• Your battery chemistry
• The regulator or charger’s supported battery profiles
• Maximum solar input voltage
• Maximum solar wattage/current
• Required connectors and polarity

If you are unsure, check with the battery-system manufacturer or a qualified auto electrician.

Can I Plug a Solar Blanket Into My Caravan’s DC-DC Charger?

Sometimes, and for many modern caravan and 4WD systems this is actually the preferred setup.

Many DC-DC chargers have a dedicated solar input and their own MPPT solar regulator.

If your system works this way, you generally want the solar blanket feeding the charger as an unregulated solar source, rather than passing through the blanket’s portable regulator first.

But there is an important catch: the blanket’s voltage must remain within the charger’s solar-input limits.

This is why you should never assume that any solar blanket can simply be plugged into any Anderson connector.

Check:

• Which Anderson connector is actually the solar input
• Acceptable solar open-circuit voltage
• Maximum solar wattage/current
• Whether the input expects regulated or unregulated solar
• Connector polarity

Are Solar Blankets waterproof?

It depends on the model.

Do not assume every solar blanket can be left out in the rain simply because it is designed for camping.

Look for the manufacturer’s stated IP rating and check whether that rating applies to the solar blanket itself, the junction box, connectors and the included regulator.

Some models have strong water and dust resistance, while others require the controller and electrical connections to be kept dry.

We have used our EcoFlow portable solar panel in wet weather, but I would still follow the manufacturer’s instructions for whichever model you own rather than treating all solar blankets as waterproof.

However, Ecoflow makes this waterproof solar blanket. We’ve tested it in the rain and it works!

What’s the difference between Monocrystalline solar cells & Polycrystalline solar cells?

Monocrystalline solar cells are best for the long term. They have a higher wattage, so they will produce more energy, and their lifespan is longer than polycrystalline.

Polycrystalline panels, on the other hand, may not be as efficient, but they’re cheaper to buy upfront and can withstand harsher weather conditions.

Are solar blankets worth it?

YES, a solar blanket is worth it if:

• You free camp regularly and rely on solar to stay off-grid
• You often camp in shade but still want to capture sun
• You move camps frequently and want flexible power input
• Your roof solar struggles in winter, cloud, or shorter daylight hours
• You want a backup option without permanent installation

NO, you probably don’t need one if:

• You don’t want to unpack, move, or reposition panels
• You mostly stay in powered caravan parks
• Your roof solar and batteries already cover your daily power use
• You rarely free camp for more than a night or two
