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.
