Criteria Used for Evaluation

Capacity

When discussing solar panels, the conversation should always start here. The power they produce and the efficiency at which they do it is important, but compatibility also comes into play. One of the first specifications you will notice in solar panels is the wattage that they are capable of producing. Obviously, the higher the number the more power it can handle. However, for whatever reason, it seems to be a universal ploy for manufacturers to exaggerate the actual wattage capacity their panels have. If you find that the solar panel you invest in is not performing at the power it was advertised as it does not become defective and many others have the same issue.

The efficiency, which usually ranges in the 20s (in terms of percent), refers to the amount of energy that the panels can convert from the sun. Again, the higher the rate, the more efficiently the panels will operate. But, also take special note to solar chargers that can work under moderate sunlight. Some will be inoperable when the slightest cloud covers a portion of the sun. Finally, there is the factor of computability. Check for USB ports and DC outputs for thousands of devices including smartphones, tablets, laptops, batteries, etc.

Portability

Given that this guide is for portable solar chargers, which most are anyway, portability does come to the forefront. For this section, it all comes down to the chargers’ compactness and carrying options. As solar panels can convert energy from the sun anywhere, chances are you will utilize this convenient technology on the go. As such, if you plan on storing it in your backpack or travel bag you do not want it to be too heavy or bulky. Solar panels that fold up, or even ones that can come apart, are a nice addition as you can pack them tightly.

But, perhaps even more important than this is integrating either carabiners or eyeholes to allow you to mount the solar charger on your backpack. This is so important because you may want to charge your device without feeling the need to stop. For example, with it mounted on your back and indirect access to the sunlight you can charge your smartphone while you are hiking or walking. Of course, this is also where the issue of cloudiness can come back to the forefront.

Durability

With any type of technology that is designed to flow voltage into electronic devices, safety will always be important. However, because these types of chargers will be used outdoors manufacturers also should add durability and protection to the solar panels themselves. For instance, you may see some with a waterproof and scratch-resistant coating. Even though you probably will not get much power when it is raining, this type of coating can be useful as it adds durability to the panels. This type of weather coating can also provide a sense of protection in accidental scenarios where water is poured on the panels.

But, more important than this is the protection that the manufacturers integrate for your electronic devices. In specific, protection against surges, short circuits, and stabilizing the voltage to prevent circuit damage. Without this protection, for example in the instance of a short circuit, your device is prone to many detrimental events. Such as the device overheating and causing a fire. This will not only fry your battery and render it useless but could also affect the solar charger itself.

Features

Truthfully, the best of the best have already been documented. But, that does not mean that there are no additional features that you can look out for. After all, hiding in the shadows may be a design implementation that puts it over the top for you. Or, it could be something as simple as a backup feature. No matter, here are some other features to keep an eye out for.

Anytime you receive a manufacturer’s warranty on a product it is a bonus and solar chargers are certainly no exception. If you find that it is not performing up to the standards you expected, with a warranty you can simply return it. Also, when developers provide you with a backup battery it gives you the means to charge your devices when the sunlight is not shining bright enough. Of course, to get the best access to the sun, it is helpful when the panels are designed to stand-up at an angle. With a built-in stand or pegs, this is possible. Lastly, you may see some sellers provide you with additional accessories such as DC cables, USB cables or carabiners.
