Nowadays numerous people use sunlight as a source of free energy. Using batteries like that you can charge various devices that require electrical energy. Modern batteries that turn solar energy into electrical energy can also be used in automobiles as well. Portable panels for vehicles work according to the same principles as the bulky solar panels that are used to seeing in solar power plants. The models offered on the market are similar and differ only in the amount of electricity that they can produce. A lot of vehicle batteries have a regulator that prevents overcharging.

Advantages of using Solar Battery Chargers for cars

green energy

Using solar energy has many advantages. Firstly, it is a free source of energy that can be found almost everywhere. In order to charge such gadgets, you need only one source — the sunlight. Secondly, this gadget does not harm the environment. Recently, a lot of people have switched to sources of electricity that don’t harm the environment. Solar energy is one of the most popular eco-friendly sources of electricity and it’s suitable for people who strive to live eco-friendly lifestyles. Moreover, solar battery chargers for cars are perfect for people who like traveling. During long trips, when there is no way to look for sources of energy all the time, a gadget that turns sunlight into electricity will be very relevant, plus no one is safe from unforeseen situations. It may happen that your car battery runs out when you are away from another source of electricity. In such cases, chargers that use alternative energy sources will be very useful. 

Types of Solar Battery Chargers

There are different models for this gadget. They differ from each other in how much energy they can generate. Some models also have a voltage regulator that protected battery in your car from overcharging. Also, some models are weatherproofed.

How do this charger work?

Car solar battery chargers operate on the principle of converting sunlight into electrical energy or heat. Modern solar chargers consist of a chain of solar cells — semiconductor devices that convert solar energy directly into electric current. The process of converting solar energy into electric current is called the photoelectric effect.

 Do solar panels work at night?

No. Solar panels do not work in the dark. It can only be used in the daytime.

Do I need find direct sunlight to charge my solar panel?

No. There is not necessary to find direct sunlight.  But it is advisable to find the most sunlight place.

Can I use it if I have not electricity car?

It is a portable charger that converts solar energy into electrical energy. You can use it to recharge any device, including a device in your car.

How many watts it can create?

Using it, you can generate 5 watts of electricity. But there are models that can produce up to 18 watts. It depends on a lot of factors. You can find a model that will be the most suitable for your needs.

What are the differences between different models for a car?

All solar panels work on a similar principle. The difference is that some models have a regulator. A device with this regulator prevents overcharging the car battery. Using such solar battery chargers you will increase its life.

Buyer’s Guide

Solar battery chargers are the best way to prevent unexpected situations connected with the lack of electricity in the car. Choosing such a gadget, pay attention to what situation you need it. Firstly look at the maximum charge that this or that model can produce.

Pay attention to the presence of a regulator that will prevent overcharging the car battery. Models with the regulator will not only provide you with electric energy in unforeseen situations but will save the car’s battery from overcharging and prolong its life. Also, pay attention to whether it is waterproof and weatherproof as well. For installation outside the car or for vehicles such as snowplows, lawnmowers or tractors, it is certainly better to choose waterproofed models. When installing a full-night battery on the windshield inside the cabin, you can choose a non-waterproof model.
