Are you searching for the best batteries for solar panels? You are at the perfect site. If you have a classy solar system, it’s cool. But if you don’t have an excellent battery of solar system, your solar system will shut down soon, and I am sure you would not like it.
There are clear statements you should consider when assessing the whole range of solar batteries like,
- What is the best battery for solar energy storage?
- How long will it work?
- How much power will it deliver?
This post will serve you with the best solar batteries of the year. Just stay with me and enjoy the full guidance regarding the solar battery.
Well, this is the time to discuss all suitable batteries for the solar panels.
Features to consider before purchase solar panel battery
Solar panel deserves better storage. You should always check the key features in solar panel battery before you made the final decision. Let’s discuss these features one by one that make your choice easier and perfect.
Budget is obviously the very first feature you should consider. If you would have the clear cut budget range in your mind, then it will definitely save you from a huge confusion. You pay for whatever you buy. So, if you pay big; you will get more features and if you pay small; you will get less features.
In short, fix your budget range first and then list down the features you want, priority vise.
As lithium ion battery would cost you higher but if your budget is not high you may consider the AGM or lead acid battery type covering the maximum features at the top priority of your list.
2- Battery Storage Capacity
Always keep in mind that you should have an eye on the storage capacity of solar panel battery. I will definitely say that you would get the best battery for solar storage in your budget range, if you focus on this feature. Ah (Amp-Hour) is the unit in which battery capacity is generally measured.
I would like to tell you one very good point that a solar panel battery with high power and less capacity can be enough for your full home energy requirements, but for the limited hours. Alternatively, battery with less power and high capacity would be enough for the longer time but for the limited applications.
In short, always try to get a solar panel battery with high capacity and high power.
3- Time of Charging
How long a battery would take to charge is another question that can’t be ignored at any cost. In my opinion, gel batteries get charged in a small time. Lithium ion batteries also charged within 3 hours or more. If battery charging time is your main concern with low budget, gel batteries (see solar panel battery types below) are best for you.
As far as the concern of flood acid battery, it takes almost a full day to be fully charged. At this point if you feel easy to allow it to be charged for a whole day and want to enjoy the minimum maintenance, this type of battery is definitely for you (check the next section to know more).
4- Lifespan of Battery
Another very important consideration is the lifespan of the battery. Get the correct information about the lifespan of the battery in question. As different batteries hold different lifespan before become less functional.
All this depends upon the battery technology, brand, and type. In a nutshell, you have to pay high to get this feature. The best practice is that keep in check the customer’s reviews and rating about the battery in question. This will surly help you to get the final decision.
5- Warranty by manufacturers
Most people normally don’t bother about the warranty given by the battery manufacturers. But this practice should not be ignored. If you pay more for a good solar panel battery, you should enjoy its long warranty time.
More trustworthy brand always charge high and gives you long span of warranty time. The duration of 20 or 30 years is good for warranty. So, always try to get the battery with highest warranty time.
Buyer’s Guide: Pick the Best Solar Panel Battery
Finding the right solar panel battery is really crucial and at the same time, it is a hard job to find the best one. Multiple factors take part in this scenario such as capability, efficiency, performance, energy storage capacity, etc. But at the same time, you can not ignore your budget. Among multiple choices available, to choose the best one, you should have a clear cut idea about the various types of solar panel batteries available in the market.
To save your time, we have highlighted all the available types of solar panel battery in the market with their pros and cons that would help you to find the best choice according to your budget. Let’s check it out.
Solar Panel Batteries Types
Before we start reviewing top solar panel batteries, I want you to get know about the different solar panel battery types. Consequently, you would have a clear idea about what to buy and what not to buy.
Generally, four types of solar panel batteries are there. Just have a look at these batteries and pick your demand wisely.
1- AGM Sealed – Lead Acid Battery
Absorbent Glass Matt is a type of solar battery in which Glass Matt absorbs the electrolytes. Flat and spiral are the two major forms of the plates present in the AGM battery type.
With lower internal resistance, it offers the advantage of exceptional conducting temperature. Moreover, like other types of batteries, these batteries do not discharge casually.
Plus, AGM batteries grasp constant charges for a long duration of time. These charges do not prone to agitate. Additionally, this lightweight and non-dangerous battery can manage the cold very well. As compared to other types of battery, it requires less maintenance, as a result, it is pricey.
2- Flooded Lead Acid Batteries
Flooded lead-acid enjoys the status of the most familiar battery. Commonly known as wet cell battery, flooded lead-acid generally use for an off-grid system. With a very low cost, these batteries are safe to use and reliable. If I zoom in its dark side, it develops corrode very quickly plus, these are very large in size.
These batteries demand constant monitoring and repeated maintenance. Additionally, it has a tendency to leakage, so always place it upright in the environment with healthy ventilation.
If you guys don’t mind regular monitoring and maintenance, this type of battery is a good option to pick. But if you don’t want you to be involved in regular monitoring, no problem, AGM batteries are available as the best alternative. Trojan, a famous brand, proudly uses Flooded lead-acid type batteries.
3- Lithium-ion Battery
If I talk about the best choice, Lithium-ion battery is definitely here to fulfill your demand. One of the best features is that it delivers amazing performance, so it is really expensive. Plus its life cycle and capacity is very good. Including its high efficiency and stability, it is really stable and safe to use.
You will be really amazed to know that Lithium-ion battery demands maintenance really seldom.
Is it not that cool?
Just install Lithium-ion battery with the solar system and take a gap for at least 15 years before first maintenance. If your budget allows to buy this expensive battery, then you must get this product.
4- Gel Batteries
The last type of battery we will discuss is Gel Battery, an additional type of lead-acid battery (sealed). Specifically designed for deep cycle operations, gel batteries work with a fumed form of silica to generate the factor that makes the electrolyte dense.
You know what?
In addition to durability, gel batteries demand zero maintenance. Moreover, these kinds of batteries offer you an excellent feature of shock resistance.
Enjoy its life cycle in the range of environmental conditions (both cold and hot climates). The gummy electrolyte of this solar panel battery makes it less liable to seep in case of a scratch.
However, if I highlight its cons, gel batteries share greater part of it in contrast of other types. They have stronger behavior towards self discharge as compare to the flooded type of batteries. Small charging design is one of its most typical negative points. They are prone to sudden over charged due to its small voltage of charging. This expensive solar panel battery produces different amounts of electricity that make them prone to over charge.

How do the batteries of the solar system work?
In the day time, solar panels generate solar energy stored in solar batteries. An inverter converts this DC energy into the AC form to be used in the dark time. The charge controller is another main component that prevents the overcharging the battery during the whole day. Plus, it hinders the backflow of solar energy produced back to the panel from the solar battery.
