The best types of batteries for solar energy:
In order to know the best solar batteries suitable for you, you must know their types first. It is very important to choose the right batteries for your solar systems because different batteries have varying levels of energy efficiency, storage capabilities, and cost effectiveness. There are also some challenges related to choosing the right solar battery, such as ease of installation. Cost, storage space, battery life, and so on. In this paragraph, we help you learn how to choose the best battery for the solar panel system, by knowing the types in detail. The types of solar energy batteries are divided into two parts, one in terms of its immersion, and the other in terms of the shape of lead slices :
First in terms of age:
1- FLA – Flooded Lead Acid Battery:
This type of solar battery is the best in which the lead plates are completely immersed in an electrically ionizable liquid, so it was given this name because it has a liquid that must be changed every certain period, like car batteries.
Flooded lead batteries are the oldest and most widely used type.
The capacity of flooded batteries ranges from 100 to 500 AH.
Its shelf life may be up to 10 years.
2- Non-flooded batteries VRLA – Valve Regulated Lead Acid
The difference between this type of solar energy battery and the first type is that the liquid inside should not be changed.
Flooded batteries do not require maintenance, and they release a negligible amount of hydrogen gas, which makes them easier to transport and install, and handling them is not considered dangerous.
This type of battery comes in three main types:
Wet This type is characterized by the fact that it can perform approximately 500 deep discharge operations for approximately 50% of its cargo. It is originally designed for navigational purposes, but it can be used in photovoltaic systems, and it is considered an economical solution.
AGM – Absorbed Glass Mat, which means electro-ionizable liquid absorbed into a sponge mat.
Gel – Lead immersed in a liquid that has been converted into something similar to jelly, meaning that it has become less fluid and more cohesive.
It must be clarified that the two types AGM or Gel are very good and can work in any circumstance and under any pressure.
As for the Gel type, it is better, more efficient, and has a longer life span, and it can perform a deep discharge cycle in which it may reach 60% of the charge in it.
Second in terms of lead chips:
1- Flat Plates
And the lead plates are in the form of compact slices, and their life expectancy ranges from 10 to 12 years.
2- Tubular plates
The bullets are in the form of overlapping cylinders, and their life expectancy ranges from 20 to 25 years.
It is possible to distinguish between the two types by simply looking, as batteries with cylindrical plates are significantly longer than those with flat plates.
How can you choose the best solar batteries
To choose the best solar batteries, there are some factors to consider:
battery capacity
One of the most important things to consider before purchasing any solar battery is its capacity and the suitability of its capacity for your needs.
Battery capacity is usually measured in -Amp-Hour -Ah, and it shows how much energy the battery can hold under specific conditions. For example, a 12V 18Ah battery can deliver one hour of 18A of current at 12V.
Shipping time
If you’re worried about the amount of sun and the time it takes to charge the solar battery in question, you’re probably better off with gels, as they charge very quickly, and lithium-ion batteries don’t take long to charge, usually around 3 hours.
Ease of installation
Another thing you should consider before buying a solar battery is how easy it is to install.
your budget
The initial cost of the solar battery itself is another thing to keep in mind, generally the more expensive the solar battery, the better and longer it will perform.
A lithium-ion battery, for example, may cost many times more than an AGM or flood-lead acid battery, but it also requires much less maintenance, is easier to install, and has better overall performance in almost every way.
battery life
Generally keep in mind that as the days go by, your battery’s ability to hold a charge will decrease, and that every battery has a certain number of hours, days, years that can be used until it becomes more or less useless or can no longer hold a charge well, it depends on Battery type, size, and brand name, but in general, the longer you want to own a battery that lasts longer, the more its price, and you can rely on knowing this information clearly from the information written on the battery.
Factory warranty
The last thing you need to know before buying is how good the battery manufacturer’s warranty is, the more you spend on your battery and the more popular the brand name, the better the warranty.
In general, a 20- or 30-year warranty is popular among companies.
