Frequently Asked Questions: Solar Chargers
What are the advantages of a solar charger over a normal charger?
You can get electricity without solar energy, but there is not always a socket nearby. The solar charger offers you the possibility to generate electricity with the help of the sun, without a socket.
In addition, solar energy can provide a better ecological footprint. Here, the energy is generated emission-free, as no by-products are created during manufacture that could pollute our climate.
Thanks to the solar panels, the chargers can be used almost anywhere with the help of the sun, giving you absolute mobility.
Who should use a solar charger?
A solar charger is particularly suitable for people who like to go to festivals or generally go camping. But solar panels can also be an asset at home.
At festivals there is the possibility to get a solar charger with an integrated battery.
You can leave it outside during the day to charge the battery. When you come back to your tent, you can use the stored energy to e.g. charge his cell phone at night.
At home there is the possibility of getting a large solar panel and setting it up in the garden, as there is often no socket available there.
In strong sunlight it is then possible to connect a small music system or even a small refrigerator to the solar panel.
For which devices can a solar charger be used?
Almost all devices can be connected to it, depending on the connection options and current strength of the solar panels.
Smaller solar panels often have USB connections, which can then be connected to common USB devices. Examples of this are: smartphones, tablets or other small gadgets.
Large solar panels can also have the right socket connections, so it is also possible to connect larger devices such as systems or fans. The prerequisite for this is that enough electricity is produced.
There are also other options for using the solar charger. So you can e.g. Charge your car battery with solar panels if they have the right connection.
Another cool option is to attach solar panels to an e-bike and then connect them to the electric motor. This allows the bike’s electric motor to be charged ecologically, which is of course perfect for a bike.
How does a solar charger work?
Using a solar charger is very easy. You can use it as long as the sun is shining. The installation angle has to be right so that the panels can produce enough solar energy.
Now all you have to do is use your end devices such as connect a cell phone to the panel to start the charging process.
Can you use a solar charger without the sun?
If we look at the small solar chargers with the small solar cells, it is basically not possible to use the charger without the sun, because then there is no energy source. But of course there are solutions for charging a device without the sun.
For this purpose you should get a solar battery charger, as this can temporarily store the solar energy. You can use it even when the sun is no longer shining.
Another similar option is to connect an external power bank to the solar panels. This has the same effect and can temporarily store the solar energy in the power bank.
But large solar systems that can be installed at home can also produce electricity without the sun. Each system works differently all year round, depending on its type, size and conditions – some can even work at night.
Types of Solar Chargers
Basically, one can differentiate between two different types of solar charging stations:
- Solar chargers with power bank
- Solar chargers without power bank
The two types are very similar, but have some differences.
Depending on the purpose for which you need a solar battery, we would like to introduce you to the two solar charging stations. With an overview of the various solar charging stations, we would like to help you make the right decision.
We will send you information about the respective solar charging station and then attach them with their respective advantages and disadvantages.
Solar Charges with Power Bank: Advantages & Disadvantages
The particular advantage of a solar charger is obvious: you can always charge your device where the sun is shining. So theoretically you have an infinite source of energy.
Charging the cell phone is now part of our everyday life. It gets particularly annoying when there is no power outlet in the immediate vicinity. A solar charger can help here. Battery chargers are not so dependent on the sun because they can temporarily store the energy in the battery.
- Easy to use
- Generate electricity ecologically
- Can be used anywhere
- Temporary storage thanks to the power bank
- Compact form factor
- Usually only USB interface
- Slow loading speed
Solar panels mostly smaller, therefore lower energy consumption
These solar batteries are ideal for festivals or other activities where you sleep in a tent. You can leave the solar battery on the tent during the day and charge it throughout the day. The energy is stored in the battery and is then available in the evening.
Solar Charges without Power Bank: Advantages & Disadvantages
Not only the smartphone can be charged with solar energy. There are also other application examples that may be relevant to you. Solar chargers without a battery may make more sense here.
These solar panels have a wide range of uses for the user. The stationary use of these solar panels is particularly suitable for generating electricity. So you can e.g. set up in the garden to have a power source there.
The larger form factor offers the possibility of using the solar panels for e-bikes or car batteries.
- Generate electricity economically
- Larger solar panels that can produce more electricity
- Depending on the device, other connection options may also be available
- Often robust and waterproof
- Depending on the sun
- Chunky form factor
- More expensive than devices with batteries
Solar Charges: Purchase Criteria
In the following we would like to show you which factors you can use to compare and evaluate solar chargers. This will make it easier for you to decide whether a particular device is right for you or not.
In summary, these are:
- Dimensions & Weight
- Battery Capacity
- Maximum Charging Current
- Charging Voltage
- Energy efficiency of the solar panel
- Simultaneous charging and quick charge function
- Weather suitability
In the following paragraphs you can read about what the individual purchase criteria are and how you can classify them.
Dimensions & Weight
Depending on the intended use, the dimensions and weight are one of the most important purchase criteria for a solar charger. It depends on whether you want to use the charger mobile or stationary.
If you need a solar charger for on the go, then it is certainly advantageous if you have a small, compact one with you. These are mostly solar battery chargers. But you have to keep in mind that the solar panel is also very compact and therefore cannot produce that much electricity.
For stationary use of the solar chargers, the large ones are best suited for this. You can then set up these in the garden or when camping, e.g. at festivals, as you usually have a permanent campsite there.
Thanks to the larger shape, there are also larger solar panels here. These therefore also have a stronger performance.
If you choose a mobile solar battery charger, you should definitely keep an eye on the capacity. This shows you how much energy you can store in the battery charger.
This factor is very important, especially with the small, compact solar chargers. Due to their small form factor, the solar panels have a lower performance than the larger devices. It is therefore important that these solar battery chargers can store the energy.
Here you can e.g. Before you want to be out and about, first fully charge your solar charger at home. The solar panel can then provide energy on the go, if the need arises.
The solar charger should have a capacity of at least 10000 mAh.
The charging power plays a very important role, especially for solar panels without a battery. Depending on the purpose, these devices should be able to deliver a certain amount of power.
The mobile solar battery chargers usually have an output of 1 to 2 watts. This is due to the compact form factor and the resulting smaller solar panel. Therefore, the charging performance is not an important criterion for this type.
The following table shows the typical performance of the mobile solar chargers:
Charging small devices, e.g. Smartphone, small power bank
Charging slightly larger devices, e.g. Tablets, newer smartphones, digital cameras
Charge from all your USB devices in a relatively short time
However, the charging power is all the more important for large solar chargers without batteries. Because of their stationary properties, they should also be able to generate electricity quickly.
At least 21 watts should be in here, but there are also some devices that can create well over 50 watts. We definitely recommend using a higher wattage here. Because even if the device says that it could theoretically manage 50 watts, in practice it is always a little less than stated.
Maximum Charging Current
A higher charging current means that you can get your end devices charged faster. The maximum charging current can be seen from the amperage of the respective interfaces.
We recommend at least an ampere output of 2. This corresponds to a charging current of 2000 mA. If this can be achieved, it is called a fast charging port. You can then quickly recharge your smartphone and other devices.
If possible, you should avoid devices with a lower ampere output than 2, as these are no longer up to date.
Of course, there are also devices that can generate an even higher ampere output; these can make the charging process even faster.
Depending on the end device, you have to pay attention to the charging voltage of the solar charger. Because some can only be charged with a certain voltage. Caution: An incorrect charging voltage can damage the end device.
Smartphones, tablets and devices in general that are charged via USB always have a charging voltage of 5V.
If you need a solar charger to charge your car battery, you have to make sure that the charging voltage is 12V.
You can of course also charge laptops with a solar charger, the voltage must then be between 18 and 20V.
So you see, depending on the device type, a different charging voltage must be available.
Energy efficiency of the solar panel
As you probably know, the solar panels need solar energy to generate electricity. But not every solar panel can convert the same amount of solar radiation equally well.
Therefore, you should make sure, especially with the large solar chargers, that they have good energy efficiency. A good value here is around 21-23%. In addition, you should make sure that the angle of installation is correct.
Since the small solar chargers do not have enough power to absorb a lot of solar energy anyway, no information on energy efficiency is given here. So you don’t need to worry about anything here.
Simultaneous charging and quick charge function
These two convenience functions should be in every charger.
In our day and age, it should be part of the fact that chargers can charge multiple devices at the same time. In addition, all connections should have a quick charge function so that you can use them to charge your devices faster.
We recommend that you take a closer look at the devices that allow simultaneous charging and that have a fast charge function.
The interface allows you to connect your devices that you want to charge with the solar charger. Depending on the intended use, you have to pay attention to certain interfaces.
Most solar chargers are equipped with USB ports. You then have the option of charging all common devices such as smartphones, tablets, etc.
But if you also want to be able to charge devices such as laptops, then you have to make sure that the solar charger has a DC connection. You should also pay attention to the respective charging voltage, which we have already explained to you above.
Of course, there are also other connection options for the respective purposes. So first think about what you want to use your solar charger for and then read the article descriptions carefully.
Solar chargers should be weatherproof, as these devices are mainly used outdoors.
Most solar chargers are robustly weatherproof. This means that most of them are protected from rainwater. They also have dust and particle protection. A small solar battery charger also has a shock protection.
What you should pay attention to are the respective interfaces of the solar panels, as these usually have no protection against water or dust. Often these have “caps” with which you can then close the connections and thus protect the entire device. So always remember to put these “caps” on.
Facts about Solar Chargerss
What is photovoltaics?
This means the direct conversion of light energy, mostly from sunlight, into electrical energy using solar cells.
It has been used in space travel since 1958. It is now mainly used on earth to generate electricity and is used, among other things, on roof surfaces, parking ticket machines, in pocket calculators, etc.
For a long time, photovoltaics was considered to be the most expensive form of electricity generation using renewable energies. But thanks to significant cost reductions in the plant components, this view is no longer correct. In the meantime, the costs in certain regions of the world are at the same level or even lower than those of fossil fuels.
What is the ecological footprint?
The potential of solar energy is enormous. The amount of energy that hits is around 10,000 times higher than the energy needs of all of humanity per year. It offers us an infinite source of energy, which is very important nowadays, as the fossil fuels are slowly but surely all being used up.
So it is certainly a good idea to invest in solar energy. You can also improve your ecological footprint. This measures how much each and every one of us pollutes the earth.
The optimal angle for solar panels
The mathematical best energy yield of a solar system is greatest when the sunlight hits the solar cells at a right angle.
But the position of the sun also changes due to the different seasons. That is why the optimal angle of installation is closer to 28 ° – 30 °. This information is especially important for fixed solar systems, with mobile solar cells the installation angle is not so extremely important, since they cannot absorb as much energy anyway.
Are there cell phones with integrated solar cells?
Yes, such cell phones actually already exist. These are very geared towards outdoor use and can withstand a lot.
These cell phones start at US$50 and offer basic functions such as calling, texting, flashlight and of course a solar cell to charge the cell phone.
Unfortunately, these cell phones are not very modern and can be compared to older cell phones from the year 2000. The major smartphone manufacturers such as Apple or Samsung have not yet launched any solar cell phones on the market.
