The Many Uses of Portable Solar Panels
Powering electronic devices and batteries on the go is an ongoing challenge. Power banks are one way to solve power issues on the go but these will run out and can take a while to charge.
When power sources are finite, there remains one reliable source of power – the sun!
If mains power is limited or you don’t have time to charge devices fully then a solar charger is an excellent option. They are perfectly suited to charging devices when you are ‘off-grid’ for long periods of time.
Portable solar panels can charge a huge array of devices including:
- Phones and other USB-powered devices
- 12v car and vehicle batteries
- Laptops via 19v DC current
- Power stations and power banks via 12v or 19v DC
Portable Solar Panel Guide
Portable solar panels come in many shapes and sizes and have various power ratings (measured in watts)/outputs.
There are quite a lot of features to look out for bear in mind when buying a portable solar panel.
Power is the most important and most confusing variable when it comes to portable solar panels. It can be difficult working out what solar panel you’ll need for the job/requirements you have in mind.
Portable Solar Panels for Portable Devices
Smaller portable solar panels designed for travel by foot or other lightweight travel are likely powerful enough to charge portable devices like phones via a USB port.
They will be typically rated at a maximum of around 25w.
This is easily powerful enough to charge two devices at once using fast-charge technology (on compatible phones).
They will be optimised for portable devices and will contain an intelligent chip that moderates output voltage based on the device(s) that is/are plug-in. These lightweight solar panels are very convenient and make effective chargers for portable devices and power banks, even in lower light conditions. They are ideal for lightweight travel.
Portable Solar Panels for Heavier-Duty Applications
Larger portable solar panels have a much wider array of uses. They can be used to charge 12v vehicle batteries, very high-capacity power banks and can even run inverters.
They will be typically rated up to some 100 – 150w or more.
Inverters take DC current and convert it to AC current. AC current is used for the vast majority of electronic appliances.
With a powerful solar panel, you can feed the power into an inverter that can then be used as a standard mains socket. You can plug in different devices or appliances into an inverter as you would into the mains – as many as the solar panel’s wattage can accommodate.
Don’t expect to be able to run loads of devices off of one portable solar panel from an inverter.
Even hairdryers and microwaves are very power-hungry, typically drawing some 500 to 800w. Still, running laptops, phones, or even a small TV or games console (like a Nintendo Wii) from an inverter-powered portable solar panel is definitely possible in brighter sunlight.
Note that you will not always need an inverter – you’ll only need one if you wish to run AC electronics from your solar panel. Some powerful solar panels are equipped with DC outputs that allow you to charge laptops directly, etc.
These more powerful models will also have your standard USB outputs for connecting USB devices and power banks.
Some portable solar panels are incredibly small and designed to be carried whilst trekking, cycling, etc. These can even fit over the back of trekking bags for powering devices whilst moving.
Larger portable solar panels are instead best used whilst stationary. They’re ideal for camping trips, fishing trips, or even outhouses, small holiday homes and other outdoor uses where power is needed.
Some awesome solar panels here. For portability, it’s very hard to beat the BigBlue 28W Solar Charger with its very healthy 28w dual USB outputs. The Anker PowerPort Solar is a great alternative from a trusted brand.
If you need a heavier duty solar panel for charging car batteries or running inverters then both the DOKIO 100W 12V Foldable Solar Panel Kit and TP-solar 120 Watt Foldable Solar Panel are outstanding options for the price.
