Solar panel usage has developed significantly throughout the world over the past 12 years. Solar power is nowadays the most prevalent form of a new generation of electricity out of everything.
Besides, solar systems have come a long way as well over that time period. And now they are more efficient than they ever were, this is because of the introduction of the solar rechargeable batteries. Let’s talk about the types of solar rechargeable batteries first.

Different types of solar rechargeable batteries
There are four main kinds of solar rechargeable batteries storing solar power:
1- Lithium-ion Battery
The lithium-ion battery is used by several auto manufacturers for the industry of electric cars. This type of battery is the same as you see on your laptops, as well as cell phones. They are becoming the most popular selection of batteries for home-usage.
They are so extensively used, as they have a longer lifespan as compared to the lead-acid battery, usually lasting about 15 years.
2- Lead-acid Battery
The lead-acid battery is frequently stated as the deep cycle battery; it has been utilized in solar applications. These batteries usually cost a lot as compared to a lithium-ion battery; however, they are less efficient as well. They are famous for having a low life cycle, with a normal life of about five years on average.
3- Flow Battery
This type of battery consists of generally Zinc Bromide & it is one of the latest additions to the industry of battery storage. Flow batteries are gaining reputation because they hold a 100% depth of discharge rather than lead-acid batteries, which have a 60% depth of discharge, & lithium-ion batteries have around 80 to 90%.
The main drawback of flow batteries is that their life is not as better as lithium-ion batteries have. Usually, they last for almost 4000 cycles having 100% depth of discharge, against the 5000 to 6000 cycles with 80% depth of discharge that lithium-ion batteries can regulate.
4- Sodium Nickel Chloride Battery
Sodium nickel chloride battery is a new entrance to the world of batteries. They are also providing lithium-ion batteries with a run for their cash as they are very eco-friendly & are fully rechargeable.
Their one drawback is that they last for about 3,500 cycles having 80% depth of discharge. The second drawback of these batteries is that they are very costly as compared to lithium-ion batteries.
How do solar rechargeable batteries work?
Solar batteries work through taking the AC energy that is generated by the solar panels & stores it as DC power for usage afterward. If the capacity of the battery is higher, then the more solar panels can charge it more.
Having a solar battery comprised as part of a solar panel system lets you save extra electricity that is generated. If your solar panels are not gathering as much voltage, you can mostly use what has been put in the storage of the battery. In this way, you will only send energy back to the grid when the battery is completely charged.
And offering you a place to store your surplus solar energy, you can use them as a temporary way out to power your goods throughout an outage.
Benefits of using solar rechargeable batteries
There are several benefits of using solar rechargeable batteries. Here are some examples:
1- Cleaner source of energy
Widely used lithium-ion solar batteries nowadays are much kinder to our environment as compared to other types of batteries. Although they still need a certain amount of lithium, less material is required in these batteries rather than other battery types, and so have less impact on the earth.
2- Performance
Solar rechargeable batteries do well, whatever the circumstances. During 0 degrees Fahrenheit, solar batteries only lose about 10 percent performance. They have to perform a bit harder in warmer temperatures of about 86 degrees Fahrenheit & above; then, there will be around a 20% drop in their efficiency.
3- Savings
You want to save your money for a long time whatever sort of solar battery you have to use. After the primary cost of purchasing your battery, harvesting solar energy can save you a significant amount of cash on your utility bills for a longer time.
4- Smart technology
Nowadays, smart technology is using batteries for more efficient work. These smart batteries can learn different weather as well as energy patterns allowing them to store extra energy when not required and use it when needed. This helps to reduce energy wastage.
5- Peace of mind
You will have a back-up in the form of these batteries during a power outage. With these solar batteries, you will have peace of mind that you would be fine for at least a few hours.
The technology of solar batteries is one of the best discoveries to appear in the past decade. Nowadays, you can take control of your life, help the earth with the use of fewer fossil fuels and by decreasing your carbon footprint, & save a lot of money while doing so.
