Solar Panel Battery Bank: Storing The Energy From The Sun

With the quest towards being able to live in a world that is more sustainable, many people are tapping other sources of energy as an alternative to traditional electricity. In this case, one of the most popular would be solar energy. Through the use of solar panels, the energy from the sun is harnessed and used to power appliances within the household, or even in a business establishment. Having solar panels, however, is not enough. Another component that can prove to be essential would be a solar panel battery bank.

As the name implies, a solar panel battery bank is simply a battery bank that is used to store energy that is harnessed from the sun. It works like the normal batteries, which are used to provide energy to whatever they are running. The only difference is that these batteries are charged through the solar panels. They can provide stored energy that can be used when there is no supply of solar energy coming directly from the sun. Read more to find best battery for solar system

Advantages of Using Solar Battery Bank

The biggest advantage of solar battery bank is the fact that it provides energy even when the sun is out. Even at night or even when it is raining, you can still have the energy that you need to power household appliances. The battery will deposit energy sourced from the panels and will have it discharged when needed.

Another good thing about solar battery banks is that they are portable. The can be brought in different places, depending on where power needs to be supplied. Even if you are on the campsite, the solar battery bank can be brought and can provide the electricity that you will need.

Disadvantages of Using Solar Battery Bank

If there is one disadvantage of using solar power battery banks, it would be the fact that the amount of energy that it can supply will be limited. Although the energy from the sun is an infinite resource, the amount that can be supplied by the power bank will be constrained based on its technical specifications. Nonetheless, if you spare time and effort in finding a high-quality solar power bank, you can find one that can hold and supply energy for an extended period of time.

How to Use Solar Battery Bank

Using solar battery banks may differ depending on the specific brand and type of battery that you are using. Generally speaking, however, it will start with setting up the solar panels, usually in the roof. Make sure that it is positioned in an area where the supply of the heat from the sun is abundant. Next, connect the wires from the panel to the charge controller. Meanwhile, the output wires will now be connected to the batteries. More often than not, they will be attached through clamps. Once the battery bank is fully-charged, it can now be used as intended.

Some Types of Solar Battery Banks

The following are some of the most common types of solar battery banks:

  • Lead Acid Batteries: These batteries have a long history of being used in off-grid applications all over the world. They are known for their large capacity and they can also be affordable, although this will largely depend on the specific type of battery that you will choose. Lead acid solar battery banks can be further categorized into the following:
    • Flooded Batteries: If you are looking for a lead acid battery for your solar panels and if you are budget-conscious, this is the best choice for you. Nonetheless, being cheap does not come without drawbacks. Some of its disadvantages include requiring ventilation and maintenance. It is also prone to spilling.
    • Sealed Gelled: This type of battery is suspended in a silica gel. It contains a paste-like material, which is basically where electricity will flow. One of the most significant drawbacks of this type of lead acid battery is that it is costly and it has minimal power capacity.
    • Sealed AGM: AGM stands for Absorbed Glass Mat. There is a protective mat that is designed in the battery. This is known for being the best when it comes to safety and cost-efficiency. They are also known for requiring little or no maintenance at all. Lastly, this lead acid battery is spill-proof and it requires no ventilation.
  • Lithium Ion Batteries: This is the most common type of battery in different applications, not only when it comes to solar panels. Compared to lead acid batteries, they are lighter in terms of weight. In addition, they also hold charge longer and they are self-contained. They can use either organic or inorganic cells. Obviously, the better option would be the batteries that are equipped with organic cells, which means that they do not contain any toxin.
  • Vanadium Redox Flow Battery (VRFB): This may be a relatively new option for solar panel battery banks but it has quickly captivated the attention of many because of the wealth of advantages that can be considered. One of their biggest benefits is that their energy capacity is almost unlimited. They can also be left without charge for an extended period without causing negative effects on their functionality.
  • Nickel Cadmium: If you do not mind spending a lot, this is another excellent option for a solar panel battery. They are also hard to find, which explains why it is not as popular as the options that have been mentioned earlier. As long as they are not deep-cycled, they can withstand long-term use. Nonetheless, compared to other types of batteries, it requires a special kind of regulator and charger.

Conclusion

In sum, a solar panel battery bank will indeed prove to be an excellent investment. It is going to increase the availability of solar energy, even if there is no sun. Nonetheless, you have to keep in mind that not all solar panel battery banks are created equal. You need to play the part of the responsible buyer to make sure that you will end up making the right decision.
