What to Consider When Buying the Best Foldable Solar Panels

Foldable Solar Panel

When buying small or large portable solar panels that you can use at home, in your RV, camping trips and other adventures, check the features.

The reason for this is that many choices might bamboozle you into buying something that is not worth the money. Therefore, here are the factors to consider before spending on one.

Wattage Depending on Usage

Solar panels with higher wattage are better. However, find out how much energy you need. In addition, there is no need to get a 120W folding solar panel while you only need 65W.

If you need this solar power system for your RV, wattage of 100 and 120 will be just fine. However, if you want one for your boat, you will need a higher wattage than that.

If you just need something to keep your mobile devices juiced so that you can catch up on email, try personal solar panels. For example, you can try the Anker foldable solar panel.

Type of Solar Panel

Without thinking too much about it, just go for monocrystalline solar panels as opposed to other types. These ones have a higher conversion rate. Therefore, they charge lead-acid batteries or your mobile devices faster.

Portability

This is the main reason why these are portable solar panels. Therefore, they need to be of the perfect weight so that you can carry yours easily.

Now, too little weight could mean that the solar has a thin-film technology. Therefore, it is best to consider weights between 2.5kg to 7kg. While the idea is to make your backpacking or camping load as light as possible, you still need the solar to be durable.

In addition, check how the portable solar power panels are packaged. For example, some come in the suitcase-style and others come with nice handles. In addition, others come with eyeholes so that you can attach them to your backpacks.

Connectivity

You do not want to buy portable solar panels for your home only for you to be unable to connect it. However, in most cases, connecting the system is so easy.

First, check whether the solar panel is compatible with solar generators. If it is, it means you will connect it directly to the solar generator, using one of the provided adapters.

However, if you want to use the solar panel with a 12V battery, check that it comes with a charge controller. Consequently, you can connect the panel to the controller and then to the battery. In addition, this is important because it protects the battery from surge, overload and short-circuiting.

Some solar panels do not come with user manuals. However, it is important that connecting the entire system be as simple as possible. Portable solar power is supposed to make your life easier and not harder.

Design and Build Quality

Some of the solar panels that we reviewed here have thin films and a fabric backing on the back. However, some are quite heavy-duty and they come with tempered glass and aluminum alloy frames. In addition, the space between the solar panel and the frame should be airtight so that water cannot seep inside.

Another thing to consider in the build quality is a stand. Most portable panels have one, but some come without so you just lay them on the ground.

It is better to get one with a kickstand whose angle you can adjust. That way, you can set the solar panels at an angle so that they can capture the most sunshine.

In addition, research shows that solar panels set at an angle capture 25% more sunshine than the ones laid flat on the ground.

Price and Warranty

The features will determine the price. Therefore, it is better to pay more for a solar panel that has fast USB charging ports, high wattage and great build quality. At least, this is better than paying less for fewer features.

However, you can expect the price of the portable folding solar panels to start at $100 and go to a few hundred.

In addition to the buying price, check the warranty. On the same note, 12 months of warranty would be great. However, if you can get one for 18 months or longer, take it.

Frequently Asked Questions

Portable Foldable Solar Panels

Here are some of the frequently asked questions and their answers. They might help you get the right mobile solar panels.

Are portable solar panels worth it?

For long-term energy needs at one place, for example, at home, the fixed solar panels that last up to 30 years are much better. However, for camping, sailing, backpacking, hiking and many other adventures, portable solar panel varieties are good. So yes, these panels are definitely worth it.

Can I connect the solar panel directly to the battery?

Yes, you can. However, if you do that, it means that your battery has no protection against the surge, overload or short circuit. Therefore, it is best to look for a solar panel that comes with a charge controller. Consequently, you can connect the charge controller to the solar panel and then connect it to the battery.

What should I look for when buying a portable solar panel?

You should look at many things. However, the most important of them include the wattage, the size and the weight. In addition, a bag or a carry handle gives “portability” more meaning. On the same note, look at the technology used. Crystalline panels are the best.

Conclusion and Recommendation

That is it for the best portable solar panel. There are so many of them, but the ten you see here might meet your needs.

If you want a solar panel to charge your devices only when you are off the grid, try the Anker solar panel. On the same note, it is made specifically for charging devices.

It also comes with the requisite charging ports to charge two or more devices simultaneously. However, please note that it does not have a battery pack to store energy.

If you need portable solar power units, try one with at least 100W rating. For instance, you might want to get the 100W Rockpals SP003. It will meet most of your energy needs when you are off the grid.
