Everything You Need to Know About Solar Battery Chargers
Solar energy is the conversion of sunlight into usable energy forms. Solar photovoltaics (PV), solar thermal electricity and solar heating and cooling are all well established solar technologies.
These technologies are becoming more common. Although solar power currently accounts for only around 3% of the world’s energy generation, its use is growing rapidly.
China currently has the largest solar energy capacity, at 130 gigawatts, with the United States at more than 62 gigawatts. Yet many other countries are also working on expanding their capacity for solar power generation rapidly.
How does solar charging work?
To catch the energy coming from the sun and to convert it into electrical energy, there are several steps involved.
Photons from sunlight carry enough energy to push electrons from their orbit in some elements, especially silicon, the material used in most solar cells. The ability of photons to disentangle electrons is called the photoelectric effect.
The first step is creating an imbalance between positively charged and negatively charged particles in the silicon. This is done by adding boron and phosphorus. The imbalance created by adding these impurities creates an electrical field in the silicon. When photons strike the silicon, the electrical field pushes the electrons toward the front of the solar cell, creating a negatively charged side. The protons that are left behind on the other side of the cell surface create a positive charge.
When the two sides are connected, using an indirect circuit like the terminals of a solar battery charger, the electrons flow into the load and create electricity.Solar battery chargers don’t directly charge the lithium-ion battery in your cell phone or iPad. Instead, they usually charge an internal rechargeable battery. This is charged through the solar modules, and their charge is, then, redistributed to your gadget so that an external electrical source is not required.
Are solar battery chargers effective?
It is easy to see the benefits of solar battery chargers – they allow you to recharge gadgets and even car batteries without an external electrical source.
There are also some subtler benefits. For example, once manufactured, solar cells do not generate any emissions, waste, or byproducts.
Although solar chargers function very well, they do have some limitations. Firstly, the power of a solar battery charger cannot be compared to a regular battery charger. These chargers are not as powerful, so it takes more time to charge the batteries.
Secondly, a solar charger gives out minimal current, so it is more useful for maintaining a charge rather than charging a completely dead battery. So, you must be careful if you are thinking of relying entirely on a solar battery charger.
Using solar battery chargers in smaller devices is still more comfortable than using them in bigger ones.
Solartab is an excellent example of such a product. It has a 13,000 mAh battery, which is more than any average smartphone and has an output power which is the minimum amount that a smartphone uses. This advanced solar charger stores enough power to be used later. The device can be carried around easily because it is flat and can easily fit next to an iPad. Moreover, the Solartab solar phone charger is so good that it only takes two hours to charge a fully discharged iPhone 6 completely.
However, you’ll need to feed the charger with 12 hours of direct sunlight to charge it completely.
Solartab is efficient as a solar phone charger, but for charging a 12 Volt battery, things work slightly different. To charge a 12 Volt battery, you require around 10 amps of DC input every time there is an output of 100 watts.
A 10 amp charger will need about 6 hours to recharge a completely dead battery. Similarly, the requirements will be higher for a 24 Volt battery.
Nevertheless, there are many advantages to solar chargers too. One of the best things about them may be that they are low-powered, so they work well as maintenance chargers.
A solar battery charger can also be a lifesaver in case of sudden battery discharge. It can help in prolonging the battery life of a stationary vehicle. And of course, they are also eco-friendly so they can help you reduce your carbon footprint.
So, it can be worth the investment, after all.
Some of the best12 Volt battery chargers are DuraVolt 20W Marine Solar Battery Charger, Battery Tender Solar Charger, DuraVolt Magnetic Battery Maintainer, and some others. Other good ones are NOCO Battery Life 2.5-Watt and ALLPowers Portable Solar Battery chargers for cars.
How to choose the right solar charger?
With so many solar chargers available in the market, it can be hard to choose a good one. Some specifics that you should look for when choosing the solar charger for your power requirements are:
An efficient battery charger harnesses the solar energy quickly, so you don’t have to worry even if there is not enough sun. Hence, they are useful in winters as well when you have comparatively less sun.
Solar chargers are available in different sizes. However, the more power you need, the bigger the size of the charger. If you’re looking to charge your car battery, you can go for a 12 Volt battery charger because it is lightweight and usually easy-to-carry.
They can be kept easily inside a car, and you can carry it around easily. Moreover, it has enough capacity to sustain bigger things like cars, bikes, boats, etc.
Usually, solar battery chargers have power between 2 to 18 volts. The ones with higher powers can be charged quickly, but the ones with lower powers don’t pose a risk to overpower your battery.
Cables & Connectors
Having a solar battery with multiple connectors gives you various options to choose from. You must also choose the size of the power cable.
If it is too small, you might find it hard to plug it into your charger.
The solar battery charger is a great invention that can help us become more eco-friendly by harnessing solar energy. So, investing in it can be the right move towards reducing your carbon footprint and making the most out of the sun.

What Is A Solar Battery Charger?
A solar charger is a device that uses sunlight to generate electricity.This electricity is then used to charge electrical devices which can include but are not limited to: cell phones, laptops, car batteries, reading lights and personal fans. Because these chargers do not have the ability to directly expel electricity into the devices, an extended-life battery pack is included within the device. This way, the electricity that the solar cells generate are stored in the battery and available to discharge through the use of a charging supercapacitor at a later time. This charging supercapacitor is the key to being able to charge devices on demand even if the charger is not in direct sunlight at the time of use. These solar chargers can range in size from fitting into the palm of your hand all the way up to the size of a picnic table to be used for charging larger things such as an RV battery.
How Does A Solar Charger Work?
A battery charger bank works very similar to both a solar photovoltaic system and a more traditional battery storage system. First, sunlight strikes the surface of the device. This sunlight is then absorbed by the individual solar cells which make up the entirety of the solar device.
Next, photons from the sunlight excite the electrons within the material, usually silicon, to create an electric field. This electric field is the force by which electrons travel to a solar battery charger kit. This battery then stores the electricity until you are ready to charge any device that is compatible. Next, a charge inverter, which is in charge of switching electricity from direct current (DC) to alternating current (AC), turns the electricity back into a more usable form. It is important to note that certain devices use DC electricity to charge their batteries while other devices primarily use AC electricity and thus some devices do not require the use of charge inverter. Finally, the electricity is expelled out of the extended-life battery and poured into the desired electrical device. Although this process appears to be rather complicated, consumers need nothing more than clear sunlight and a few seconds to begin to see the benefits of these devices.
What Kind Of Devices Can A Solar Charger Charge?
In theory, any electrical device can be charged using a solar build battery pack as long as you are willing to wait long enough. In practice however, only certain devices can be realistically be charged with a solar charger. Typically, these devices include but are not limited to: cell phones which are only used once or twice per day, laptops that are given sufficient time to fully charge, vehicle and RV batteries which can be given multiple days to charge, and a variety of other small devices which rely on exclusively electrical power such as reading lights and personal fans.
Many view these devices as being especially useful when going camping or when living an extremely nomadic lifestyle on the go which does not always afford an electrical outlet. A peak power supply is ideal for charging any device. This means that the battery within the small solar device is at maximum capacity. This way, it can fully discharge into the device you wish to keep electrified. This is because batteries, in order to extend their usable life, should regularly be discharged all the way. This ensures that it can continue to fully store its rated amount of electricity over time. Finally, it is important to consider how often you may need to use the devices that you are intending to charge with a solar charger. This is because small solar chargers may not be capable of meeting these more rigorous demands.
Who Are Solar Chargers Best Suited For?
Solar chargers can be useful for anyone hoping to charge electrical devices while entirely off the grid.
Small solar energy devices are small enough to be stored and convenient enough to use anywhere that the sun is shining regardless of how far away you are from modern civilization. The only determining factor of the charger is usually its size. This determines the rate at which certain electrical devices will charge. If you are able to be patient and only use the device once or twice per day, ,a small handheld battery charger bank may be appropriate. On the other hand, if the device is needed frequently or needs to be able to be charged in a shorter period of time, the solar battery charger kit should be much larger. Common uses for solar chargers are camping trips, those who choose to live a more nomadic lifestyle out of an RV, or simply those seeking to reduce their carbon footprint without giving up many modern day amenities.
