When considering a solar charger, we always have some questions like, what is solar battery and why use a solar charger.
Having a solar charger during trip, means you can keep your USB devices full of juice all the time with a sustainable source of power. Solar charger costs more but also more eco-friendly than a normal portable power bank by comparison.
Here we collected 5 top solar chargers for you, you may find the best solar charger for iPhone or best solar battery charger.
Although a new wave of chargers has come onto the market, just like ultra-portable, pocket-sized or other solar charger with larger solar panel which is essential for camping trips or anywhere where mains electricity is hard to come by. But when you’re looking for the right solar charger, consider what you’re charging with it. Camping on a whim, mountain hiking for several days, road trip with all big family, which one is your favorite?
And also take the devices in the consideration. If you just want to charge your smartphone, maybe a portable solar charger is enough, but will you also want your camera, tablet, Bluetooth speaker full of juice when you need it outside? This time the larger solar charger with larger solar panel can be the first option. What good is, there are also solar chargers which combine portable power bank with LED light and solar charger function.
With all these solar chargers, real sunlight is required. But it doesn’t matter if it’s overcast – it’s the UV rays which give the chargers life.
But knowing more about the solar panel, which is the most important part of a solar charger, is a good way to choose a suitable solar charger. Solar panel refers to a panel designed to absorb the sun’s rays as a source of energy for generating electricity or heating. Solar panels seem simple, but using one to charge a battery takes more than just leaving one out in the sun. These devices perform best in direct sunlight on a clear day, which sometimes left us at the mercy of the local weather.
On the most basic level, a panel left in a well-lit area converts light energy into electricity that charges an internal Lithium Polymer (LiPo) battery. The battery then stores the energy from which you can charge your phone or other mobile devices. Here to check out our articles about solar phone chargers for more information.
What Is Important in Selecting a Solar Phone Charger?
The efficiency of a module determines the area of a module given the same rated output – an 8% efficient 230 watt module will have twice the area of a 16% efficient 230 watt module. There are a few solar panels available that are exceeding 19% efficiency.
Solar Panel Details
Efficiency is a good indicator of quality, and the efficiency in part depends on the type of panel the solar charger uses. Most commercially available solar chargers for cell phones are first-generation crystalline silicon, which is known for having higher efficiency ratings than second-generation panels. These panels do better at generating electricity, even in low-light conditions. And the latest cell of solar panel is Polycrystalline silicon, which is with higher efficiency and conversion rate.
