We have smartphones, microwave dinners, and instant online payment methods. In this world of endless conveniences, there’s a quick solution for every problem.
Portable power is no exception! Years ago, the only way to get electricity while camping was to bring a generator or stay at an RV park. But now, you can charge your devices literally anywhere the sun shines–with portable solar panels.
What is Portable Solar?
Portable solar is electricity from the sun–on the go! Unlike large rooftop solar setups, you can take portable solar panels anywhere (hiking, backpacking, boating, you name it!)
Here’s how solar panels work:
Solar panels have solar cells made of silicon that harness the sun’s rays. They have positive and negative layers that create an electric field. You can channel this electricity (DC) through a charge controller and into a battery. Next, you’ll use an inverter to change DC power into AC power to charge your electronic devices.
However, some portable solar panels don’t need an inverter or charge controller. This type of panel is often called “plug and play”. You simply set up the solar panel and connect your device to the USB output.
Types of Portable Solar Panels
These are the main types of portable solar setups:
- Solar phone chargers. These small, foldable panels produce 5 to 20 watts.They’re great for backpackers and campers.
- Flexible panelsThese generate 20 to 100 watts of power.
- Rigid panels with a kickstand.(Usually 50 watts or more).
To figure out what type of panels will work for you, there are two main things to consider. Where are you taking your panels? How much power do you need?
Calculate your energy requirement by making a list of the devices you want to power (phone, small fan, lights, etc). Then add up the power consumption of each device (measured in watts). For example, if you only want to charge a cell phone (around 10W) or two, a 20 watt panel will be perfect.
Tip: Choose panels that provide slightly more energy than you need in case sunlight is sporadic. You can also get more than one panel to cover your total energy requirements.
Advantages of Portable Solar
You already know that portable solar is all about convenience. But let’s shine a light on a few more benefits:
- Easy to set up. No roof mounting needed. Place anywhere there’s sun.
- Stash in a backpack, pack in your suitcase, toss it in your boat. (Many panels are water resistant).
- Won’t take up space.Portable panels are lightweight and small. If you choose a foldable style, they won’t be the reason why you had to leave your extra snacks at home.
- Emergency backup power.Generator failed? RV park too far away? Use your portable solar panels as backup.
- Place them where needed.Ever park your van/RV with rooftop panels, only to have to move it an hour later when the sun shifts? Portable panels aren’t stationary, so they can “follow the sun”.
- Unlike generators, solar power doesn’t pollute the airwaves and scare away the critters.
- Clean Energy. Especially when paired with environmentally-friendly lithium batteries, portable solar panels provide clean, renewable energy.
- Grid Independence.Go ahead, travel far from the power grid. With portable solar, your only limit is a cloudy day.
- Supplement rooftop panels.Great for when you need a little extra power, but there’s no more room on the roof!
