For most of the outdoor enthusiasts, the solar power bank is an essential gadget. It is an excellent option for charging your cell phones, cameras, and other gadgets. With the help of it, you can charge your devices even when there is no availability of power source. These ones are very convenient and portable as well. These chargers that come with one panel have a compact design. But these recharge themselves slowly using the Sun’s energy. Chargers that come with multiple panels increase the charging speed.
How Does Solar Power Bank Work?
Solar energy is an Eco-friendly way to generate electricity. The solar power bank is equipped with a small built-in panel that helps to charge a rechargeable battery. The panel is usually a photovoltaic cell. Here, phosphorus replaces the silicon and then creates a negative charge. And, boron replaces silicon to the other end that creates a positive charge. It helps to create an electrical field.
Due to the electric field, electrons can move around easily within the cells. When sunlight (a stream of photons) hit the panels, the photons strike the free electrons. And then, these knock it out of the circuit. Then, a conductive plate collects the electrons to create electricity and recharge the battery.
Most people prefer to choose Lithium based batteries. It is because Lithium has a high tendency to lose electrons. It indicates that electrons can move from one terminal of the battery to another terminal easily. These ones are ideal for charging your phone.
Benefits of Using a Solar Powered Battery Charger
The solar powered battery charger helps to store energy. And it allows the user to use the energy when it is a cloudy day. It is the primary benefit of this charger. You can even charge your cell phone battery without taking them out in the Sun.
The essential benefit of solar powered battery is that these ones don’t need external electrical sources to recharge your batteries. As there is no need for using an electrical source, you can get a few subtler benefits. The solar cells create no emissions, waste or byproducts. The photons pass through the silicon. And here, the electricity comes from the transfer of energy from photon to an electron. During the process, it frees the electron and allows it to flow. Electricity is an energy carrier, not a form of energy. You can generate electricity through the photoelectric effect.
What are the Types of Solar Energy Chargers?
You can get three types of chargers that are available in the market:
- Simple 1 or 2 stage controls
- PWM (pulse width modulated)
- Maximum power point tracking (MPPT)
Simple 1 or 2 Controls: It comes with shunt transistors. These ones help to control the voltage in one or two steps. Its function is to short the solar panel while a certain voltage will arrive.
PWM (Pulse Width Modulated): It is a traditional type charger. Anthrax, Blue Sky, etc. are some examples of it.
Maximum power point tracking (MPPT): MPPT solar charge controller is very famous in today’s market. These ones can identify the perfect working voltage and amperage of the solar panel exhibit easily. The output you can get from this one will be more than 10-30% compared to a PWM controller.
Solar Power Bank Buying Guide
Multiple factors are there that you need to consider before buying the best solar power bank. Here, we have given a few tips that can help you to choose the right one as per your needs.
- Battery Capacity
- Solar Panel Specs
- Portability
- Charging Ports
- Battery Type
Battery Capacity
You need to determine the battery capacity first. The battery stores energy. It is measured in mAh (Ampere-Hour) or Wh (Watt-Hour) units. It lets you know about the amount of power that the battery can put out at a certain duration.
Usually, we want to know how much charge our device is draining. How much we can charge a full battery depends upon the mAh number on the power bank. That’s why you should determine for which purpose you will use the solar power bank.
Solar Panel Specs
Usually, these banks can be charged with a standard power outlet. You don’t need to rely upon the power grid entirely. It allows you to store power using the Sun. While you’re going to determine the quality of the solar panels, you need to examine both the panel cells. Besides, you also need to test the panel size. The larger panel will collect more energy from the Sun. You need to look for the specs also of all solar panels that you are purchasing. And then, you need to find out the power output. Sometimes, you may need to pay a little bit extra for achieving the highest efficiency. Besides, you also need to consider the size of the solar power bank you are charging via these panels.
System Portability
As soon as you decide for which purpose you will use it, you need to consider its portability. You should buy lightweight ones that you can carry anywhere. In case you want a power source for a camper-van, then try to buy those things that you can move around. A few higher-capacity power banks are available that are slightly larger than a car battery.
Usually, panels are fold-able. And a few banks are there that come with panels built onto the battery.
Charging Ports
When it comes to the battery capacity and portability, the number of charging ports required depends upon you. A few users want to charge multiple phones or tablets at the moment. In this case, you can look for those banks that have multiple USB ports. The larger ones have numerous plug-in options ranging from USB, standard outlet prongs, to additional option. If you are looking for backup at home in emergency times, then try these ones. Families who are searching for an off-grid car camping solution can also use it.
Battery Type
Lithium-ion polymer power bank batteries are mostly available in the market. However, many variations are there, such as lead-acid or saltwater batteries. And plenty of factors are also there to consider before deciding the appreciate battery type. You need to know the depth of discharge and the entire lifespan of the battery.
The depth of discharge means the full storage capacity of the battery. Actually, it indicates the battery’s state of charge.
On the other hand, the Lead-acid batteries are traditional off-grid solar solutions. These ones have a shorter lifespan compared to the other battery types. Usually, these have a lower depth of discharge. Most people prefer to use lead-acid batteries while converting the entire household energy system to solar. And these are budget-friendly also.
Again, the Saltwater batteries are a homemade DIY solar solution. It is a perfect Eco-friendly option as the battery depends on saltwater electrolytes. There is no heavy metal. But the drawback is that there is no information available regarding its longevity.
Lithium-Ion Polymer batteries are the prevalent battery available in the market. These ones have a longer lifespan and a higher depth of discharge compared to other battery types.
How can I speed up my solar power bank?
Here, we have given you five easy ways to speed up the solar bank.
Charge outdoors
If you place it in a hotter place, then the charging speed will get slower. It is the most important thing that you need to know at first. The high temperature usually decreases the efficiency of solar cells. Therefore, if you want to increase the charging speed, you have to charge it outdoors. And the place should be well ventilated. When the solar panels are inside the backpacks, these can offer faster performance. And it will work a bit faster when you take these out from the backpacks.
Open windows if charging outdoors are not possible
While you are charging a solar power device, the efficiency reduces from 20% to 50%. Windows don’t allow the cells to get activated. Even, these can stop the activation state for some time. But it happens when the windows contain UV protection. That’s why it is better for you to open the windows while charging.
Make sure that solar cells are facing towards the Sun
Most of the time, we keep the solar panels flat on the table. And we think that it will work properly. But it is not going to happen. It can get merely half-power compared with tilting the panel towards the Sun. That’s why always make sure that you placed the solar panels facing towards the Sun. However, the charging speed can be reduced a little bit. It is because the inclination of the Sun in relation to your device changes constantly.
Every solar panel doesn’t have a similar efficiency
All panels are not similar although these look the same. You can choose the Crystalline panels that can charge two times faster than the thin-film panels. However, both come in the same size. Usually, the rigid ones are quicker and more durable than the flexible ones. Therefore, you need a flexible one that is 2× larger than the rigid panels. Thus, the same amount of power can be gotten.
Try to use shorter cables
If you’re using a shorter cable to connect the panel and your device, then it doesn’t increase the charging speed. However, always try to use a long cable for the panel so that it can reach full sunshine.
Solar Power Bank vs. Solar Charger
Here, we have given a perfect comparison between these two. The first one has portable chargers and internal batteries. The batteries store electrical energy and then power your phone. But it weighs lighter than the solar chargers. On the contrary, these chargers use solar panels and turn solar power into electricity to power your device.
Pricing
The price range of these portable chargers are from $30 to $250. However, it depends on the brands, the amount of energy in watts, and the charging capabilities. A few high-end chargers can provide power up to 200 watts. And these ones can charge car batteries. You can carry the banks from one place to another. You can choose the expensive ones also if you require large ones. But those who have a lower-end price range can offer approx 7-14 watts of power. A few chargers are there that need more than six hours of direct sunlight for charging your device completely. But it depends upon the exact watts number and the brands.
If you want to charge your device only, then you don’t need an expensive power bank. Portable ones are convenient in this case. The price range of these portable ones is from $20-$125. Hence, the price depends upon the brand and energy storage capacity.
Sizing
The size of chargers differs according to the brands.
Weight
If you want to buy lightweight ones, then you can choose lower-watt chargers. These are lighter than a pound. However, you can use a RAVPower 24 watt charger that weighs 1.65 pounds. A few models are available that have a larger capacity. These ones can weigh up to 13-14 ounces.
