Portable solar panels: what they are, features, applications

Portable solar panels are an independent source of energy. They are often used by tourists during their stay out of town. This is a great solution to recharge your phone and other gadgets. The devices are charged by the energy of the sun.

Types of portable solar panels

Mobile solar panels are usually classified into two main categories, each variety has its own features, pros and cons. Portable solar panels are:

• thin-film;
• crystalline;
• made on the basis of silicon.

Thin membrane is a solar cell type with photovoltaic material imprinted on the surface. The key advantage of this variety is flexibility. Such batteries can be placed on a variety of materials and are affordable.

Flexible versions of solar panels are obtained by placing photovoltaic cells between polymer layers. The cheaper varieties use PET polymer, the more expensive ones use ETFE. The second type of solar panels has improved light transmission when compared to PET. It is stronger and more reliable, which is especially important when the battery is exposed to high temperatures and precipitation.

Crystalline modifications are made on the basis of silicon. Manufacturers offer versions with polycrystalline and monocrystalline elements. Silicon solar cells are not as flexible, but they can be used on inclined surfaces, for example, on the roofs of motorhomes. This variety is more durable compared to film solar panels.

Recommendations for selection

At the stage of selecting mobile solar panels, attention should be focused on several parameters:

• power;
• voltage;
• The availability of cables in the original package;
• moisture resistance.

A battery with a rating of 100 watts will not be able to deliver more than 75 watts. If a more powerful version is required, multiple panels can be combined. It is allowed to combine in parallel and in series.

The operating voltage refers to the limit value, under the nominal one that will be applied. This is one of the key characteristics.

You should also take into account that to connect the panel to the battery or consumer will need a cable. It is desirable that it is included in the package, this information is on the packaging.

Mobile solar panel must be robust, to withstand wind and snow loads. Water resistance is equally important, especially for travelers. Most models of portable solar panels satisfy this requirement.

It is recommended to buy modifications that are equipped with a charge controller, a battery and a set of wires. Travel models are better used in conjunction with the battery.

Pros and cons of portable solar panels

The key advantage of portable solar panels is their versatility, they are able to power any gadgets. Such devices do not create a heavy load when traveling. They are easy to install and operate, just find a well-lit place.

The minuses of mobile solar panels are associated with a decrease in performance in insufficiently lit weather. It is advisable for travelers to stock up on batteries capable of storing a charge for use on cloudy days and in the hours of darkness.
