Solar panels vs solar blankets; what’s best?

Solar technology has come in leaps and bounds, and there is some truly awesome gear on the market today.

If you haven’t already seen one, you can get solar blankets which fold out and act as solar panels. They are similar to a picnic blanket, although a fair bit heavier and with a cable you run to a regulator and then your batteries, to keep the power flowing in.

They are super impressive, and do an amazing job at charging batteries, and I can’t wait to see how technology improves things in the next decade. The real question though, is what’s better now; solar panels, or solar blankets?

What’s better; solar panels or solar blankets?

What’s good about a solar blanket?

If you are looking for a solar blanket review, you’ll find lots of people are very happy with them. Solar blankets are very portable, less fragile than normal panels, can be packed much easier and work extremely well as a backup or extra panel as the conditions require it.

They are also portable, so you don’t have to worry about shade and where you camp – you can just move them into the sun.

What’s not good about solar blankets?

There are a couple of things that I don’t like about solar blankets:

Easy to steal

Unfortunately, we live in a world where some people don’t feel the need to work for their gear; they just take someone else’s. Solar blankets are super easy to steal. They are relatively light, can be folded up under your arm and have no way of being secured.

I’ve seen a few of them laid out at camp sites, and wondered how often they get nicked. Normal style panels can be locked to drawbars or tow bars if you have to leave them, and they are also much harder to tuck under your arm and walk away with!

What makes things even worse is they are extremely expensive when compared to your average monocrystalline panels, so if they do get taken you are going to feel a lot worse off than if it was just a cheap, solid panel.

Hard to hang in a good position

You can get all sorts of different size solar blankets, but I’ve yet to see a way of hanging them in a decent manner. You can put them on your wind screen, bonnet, roof or the floor. None of those solutions work flawlessly.

Panels work best when they are facing the sun; how many hours a day does your wind screen face the sun? Probably an hour or two, if you park the car in the right direction. What happens in 2 hours time when the suns moved? Do you turn your car around?

I’ve seen these used on wind screens, and you are forever ending up with shadows from snorkels and antennas on your solar, which dramatically reduces their output.

If you put it on your bonnet, and you’ve been through mud and grit then you are likely to scratch the paintwork, and on the floor it doesn’t face the sun either, and is at risk of being stood on, or driven over.

Now, I understand that these are pretty good at absorbing sun in what ever position they are in, but they can only do so much.

We’ve been laying ours on the floor often, but they tend to get leaves or dust on them pretty quickly, and I’ve even had my kids run over them!

If you can, get ones that have legs to stand them up; they are far easier to use and far more efficient. I don’t like the idea of trying to hang or lay these; they are just annoying. These are more like folding solar panels, but they are blanket style and tend to be really wide, and not very tall.

Seriously pricey

When the cheapest 120W solar blanket you can buy is about $180 (with questionable quality), you’ve got to wonder about whether solar blankets are good value for money.

If we look at the top end of the scale, you’ll pay $2350 for a 112W Redarc Solar Blanket. No doubt these are some of the best solar blankets on the market, but you pay for it!

For that price, you can get 15 and a half 200W normal 12V solar panels. Obviously, you probably don’t need that, but it gives you an idea of how much more expensive they are.

Now, you can buy a kings solar blanket at 200W for around $240, so there is a big difference in pricing if you are prepared to look at other brands. We’ve actually done a Kings Solar Blanket Review, and I’m not sure I’d get another.

Speaking of price, if you are looking at solar panels on eBay, take a read of this – eBay solar panels; how to avoid getting ripped off.

How durable are they?

Another area that I am keen to see information on is the durability. Folding solar panels and fixed normal panels have proven themselves.

I’ve had 600W of panels mounted on top of my 4WD and camper trailer for several years now, and with some decent bracing they’ve copped with some truly terrible 4WD tracks without any issues.

I do wonder how long a solar blanket will last if you are opening and closing it on a regular basis, or using them in normal conditions? I’ve found some cheap solar blankets tend to get moisture ingress very quickly, and you get bubbles under the surface which can’t be good for anyone. Only time will tell.

They require you to work for your power

If I’m completely honest, I prefer a solar system that does its thing without you touching it, ever. If you can, a fixed solar system that is oversized is the way to go; you never have to set anything up, you never have to monitor battery voltages, and you never have to move anything around to follow the sun.

Solar blankets are a bit more user friendly in terms of setup time than a folding panel set, but they certainly don’t involve doing nothing at all.

Who sells solar blankets?

If you are in the market for solar blankets, you can get them from a heap of different companies:

Adventure Kings (4WD Supacentre







Allspark from Offroad Living


Portable or fixed panels?

There are pro’s and con’s for portable and fixed solar panels. If you want a comprehensive list of things to think about, read this – Fixed or Portable solar panels; which is better?

Going forward

The future is very bright; these will come down in price like normal solar panels have done, and soon you’ll be able to add one to your camping arsenal for a much cheaper price.

For some people, they work very well. For us, we’ve gone with permanently mounted panels on the Reconn R2 and Dmax, and have a folding solar panel and a Kings Solar Blanket as backup, or for when we park in the shade. 

If you move regularly, and would be getting folding solar panels anyway, check the solar blankets out; they are pretty amazing bits of kit.

We will shortly be installing lithium batteries and a much bigger solar array on the Reconn R2, and I can’t wait!

  1. Hey Michael,

    I’ve noticed that as well; and our kings one had water underneath just from condensation over night; pretty average!

    Cheers for the extra information, and have a good one!


  2. Michael B says:

    When they get wet, the backs of some fill up with water (Kings 200W, Ebay 120W) and they weigh 5-10kg extra and don’t dry out easily. They still produce power once they do dry out but are fat and less easy to fold. Only buy the ones that have no “canvas” but are a hard plastic or metal with minimal fabric as joiners. The ones like the semi-flexible panels but with the ability to fold are the best.
    And most are way over-rated – just like most panels are.

  3. Hey Graeme,

    You aren’t the first person to mention this, and I’ve seen them get damaged just leaving them out overnight and the condensation getting onto them. I’d like to know if the high end ones are waterproof. That said, I reckon I’d go for a panel any day of the week, especially seeing how many people struggle to set a blanket up in a way that points remotely towards the sun and doesn’t scratch anything nearby.

    All the best

    I bought a solar blanket, 200 watts, it worked well for a week, then after a shower of rain it stopped working. I’m now told that solar blankets are NOT waterproof! If your camping outdoors, and it rains when your out hiking, you’ve just lost your $200 solar blanket like I’ve just done! Stick to glass solar panels unless you stick to the suburbs and keep your solar blanket in the shelter of the porch alongside your 240 bolt power outlet where you don’t even need a solar panel!! Stick to the glass panels! Ie. If you’re camping outdoors!
