Remember when computers were too heavy to lift? Depending on how old you are, maybe not. Either way, now they can fit into a pocket and the weight is barely noticeable. The same thing has happened with solar technology. First presented as heavy solar panels – that needed a lot of muscle to get them onto the roof –we are now at the other end of the spectrum. Solar panels called ‘Solar Paper’, due to their small size and weight, can now be used to charge a whole host of small appliances such as mobile phones or laptops.
Solar Paper fits into the pages of a book rather like a bookmark, only it’s a bit bigger than most bookmarks at 19x9cm and just 4mm thick. At the top end there is a USB charging port 11mm thick. Each ‘page’ of this solar panel device provides 2.5W of power. At 128gm you can easily stick two or three together and use them to charge up your phone, external battery, camera and other devices. In fact, four solar panels can be joined together to juice a larger device such as a laptop. And don’t worry, the devices are embedded with magnets so you won’t lose them.
Solar Paper is ideal for the person on the go who does not have time to take their phone home and wait for it to recharge. You don’t even have to find a power point to plug in your usual phone charger. Solar Paper means you can get power from the sun while you’re walking down the street, enjoying a coffee at an outdoor cafe, waiting to play tennis or riding a horse. It’s also ideal for camping, when there’s often no power available.
A nifty feature of Solar Paper is that it turns on automatically. Previous models switched off whenever a cloud hid the sun or if you walked through a shadow. They had to be rebooted manually. This could be annoying and frustrating, especially if you were busy and didn’t notice the shadow.
Another feature is the LCD screen that tells you how much power is being delivered at any one time. The advantage of this is that you can easily choose the correct angle of orientation to the sun for the best result. It also helps you understand how different kinds of weather will affect its ability to charge your device.
It’s water resistant, which is handy if a sudden shower strikes when you are out and about, or if your little brother sneaks up with a water pistol. There are also grommet holes, allowing you to attach it to things such as the outside of your backpack. So you can put it to work charging your phone while you are out on the go.
Many devices such as this that are already available don’t work because they’re too small to generate the amount of power needed. Others are too bulky to carry around easily. The new Solar Paper works well on just one panel and you can boost its power by adding up to three more panels, depending on the device you need to use it for most. These panels can still fold over for ease of transport when you are not using them; the magnets ensure that the parts will stay together.
Solar Paper solar panels are easy to carry around due to its compact size and light weight; you’ll hardly notice it. It certainly fills a niche, giving us a product we can trust to do the job we bought it for. And talking of buying – it is very affordable, given the usefulness it provides. You will no longer have to worry about your phone battery running out just when you need it most.
Three panels are advised for charging a Smartphone; this will be enough to charge it even in cloudy weather. The single panel will charge an external battery, iPhone 6 or Samsung Galaxy while four will be needed to charge an iPad Air 2.
Being able to decide on the amount of power – and therefore pages – you will need gives added versatility to this device. If you start off with the smaller size and find it is not quite enough, it is a simple matter to upgrade by adding another panel to the original. When the design of anything has obviously been well thought out, the result is something that almost everyone finds practical. Maybe one day something smaller and better will come along, but for now this has filled the niche, admirably ticking all the boxes of size, weight, affordability, ease of use and reliability.
