Best Portable Solar Panel – Top Reviews for 2021

Imagine if you could just walk around with a portable solar panel that can power your devices through your trek? No more dead battery in your cell phone, GPS, MP3, tablet, or flashlight. But it can’t be that easy to carry around solar panels. Can it?

When we say solar power, we’re used to thinking of massive panels lining the roof of a home or cabin. We might then think that these require a large investment and that they are difficult to install, all of which is somewhat true. Yet not all solar power systems are the same.

Portable solar panel kits, for instance, are small, light, and easy to carry in any off-grid situation. If you’re looking for an environmentally-friendly way to solar charge your phones or small appliances on the go, these foldable solar panels are likely an ideal choice.

Portable solar panel kits work in the same way regular solar panels do, by converting sunlight into electricity with the help of photovoltaic (PV) cells. These are comprised of two thin layers of silicone, one of the most common polymers of man-made products. In the presence of light, these silicone layers create an electric charge that is then harnessed by the system and used to power some of your appliances. Alternatively, this electricity can also be stored in a battery or bank for later use. Unlike the solar power systems you see on rooftops, even the best portable solar panel kits will have a relatively small wattage.

Low wattage means that these foldable solar panels are not capable of generating as much electricity, but they shouldn’t have to. There’s a reason why these products have a smaller surface and fewer PV cells, namely that they are made for increased mobility, so you can take them with you and have electricity anywhere you go.

How much energy a solar panel can generate depends on three elements: the size of the foldable solar panel, how much time it spends in direct sun, and the panel’s efficiency or capacity to collect power. Typically, mid-range products will be able to generate from 150W to 350W per hour in standard test conditions. This may not seem like particularly much, given the fact that an average household will need about 15-20 kilowatt-hours (kWh) per day. However, during a camping or an RV trip, these foldable solar panels can be lifesavers. A small, 50W solar panel for camping is enough to charge your smartphone or a similar electronic device. Several LED lights and a small fridge or TV would need anywhere from 120W to 150W per hour. The same amount of wattage is usually found on solar panels for RVs, since recreational vehicles can usually manage with that amount of electricity.

If you’re on the hunt for the perfect portable solar panel for your adventures, take a look at the most popular items, reviewed below. You’re sure to find one that fits your needs and can help you to create your very own solar power bank.

How to Choose the Best Portable Solar Panels

How to Choose the Best Portable Solar Panels

The best solar panels for you are the ones that successfully meet your electricity needs while travelling. Things you should consider when deciding which portable solar panel kit to go with are the number of devices you need to power or charge, but also several technical specifications that vary from one product to another, like how easy it is to install the solar panel.

Solar Panels and PV Input

There are two types of solar panels: monocrystalline and polycrystalline. The second are the least effective, with a conversion rate just under 20%, but are usually easier to transport. On the other hand, monocrystalline foldable solar panels are more durable and efficient, with their downside being a slightly higher price. You’ll be able to easily tell them apart by their STC rating or module efficiency.

The PV output is what sets the best solar panels apart from the others, since it says how much electricity they can generate at a time. The higher the number, the faster you’ll be able to charge your laptop, phone, or other batteries. If you just need to power a few solar lanterns, you’ll need less power, for example.

Battery and Charge Controller

Because most portable solar panels come without a battery or bank, you’ll likely need to purchase one separately. It’s important that you find an adequate, durable, deep-cycle accumulator, as it will have to be constantly recharged and discharged. Ideally, this battery should be able to keep a charge for a long while without using electricity.

The charge controller element of your foldable solar panel is crucial to maintaining the health of your batteries, as it essentially links the panel to the battery. This mechanism is also responsible for keeping your accumulators healthy by stabilizing the charge, as well as preventing any overcharging from taking place. (And don’t forget the solar inverter, which converts the power from DC to AC!)

Durability and Portability

The durability of your solar panels for your RV or boat is another element you should pay attention to. Since you’ll be travelling in the great outdoors, weather won’t always be friendly, so you need to be prepared for it in every way possible. Although most panels are weather-proof, you should make sure that the solar kit you’re considering can withstand rain and wind, as well as generous temperature variations. Ideally, the best kits are also easy to carry. You’re outdoors for a reason so being able to move and enjoy as much of nature is likely your primary concern. Whether you’re looking for the right kit for living off-grid, or for RVs, calculating how much energy you need should always be the first thing you do. This will help you understand what type of product you’re looking for, as well as narrow down your search quite a bit.


People have successfully used solar energy for camping off-grid ever since the technology first became available a few decades ago. Since then, solar technology has grown in leaps and bounds and continues to improve every year. Following suit, solar products that used to be scarce a few decades ago are overtaking the market. Recreational activities have completely changed since involving this new equipment. In many cases, solar technology, like these portable solar panels, can save lives and make emergency situations much better. (Looking for more cool solar articles?
