Using a solar panel system has become increasingly popular due to rising energy prices as well as the destruction that fossil fuels inflict upon the world. Renewable energy is starting to become more cost effective, and the low environmental impact is a definite plus point. However, if you want to utilize solar energy, you will have to invest in energy storage as well. This energy storage can be achieved through the use of solar batteries.
That said, the sheer number of options in the solar battery market can make it difficult for you to make a decision. This is why we have provided a list of solar battery brands, as well as a buying guide featuring a number of qualities that you should be looking for in solar batteries. Once you have educated yourself on how the best solar batteries work, making a decision will be far easier.

Depth of Discharge
Even if your solar battery is fully charged, you might not be able to use the entire amount of energy that it contains. Depth of discharge refers to how much solar power storage you can utilize without damaging the battery. This depends on the battery types that you are looking into. Flooded lead acid batteries will have a very different discharge depth from gel batteries. The best batteries often use a deep cycle which means that you can use most if not all of the energy that is stored within. Deep cycle batteries such as AGM batteries should be preferred because you will have a greater amount of energy that you can utilize.
Level of Maintenance Required
Some solar batteries require far more maintenance than others. A sealed lead acid battery would generally require more care than a maintenance free gel battery. Lithium ion batteries are also great but they can damage the environment due to a lack of disposal options. A deep cycle battery tends to require less maintenance due to the lack of an arbitrary limit to how much it can be discharged. It is important to note that some solar batteries can self discharge which is useful because it can lead to lower maintenance requirements since an important maintenance activity is being taken care of automatically.
Type of Installation
This depends on a number of different factors. The number of solar panels, the type of solar battery and the size of your battery bank are all factors that affect whether or not your solar battery is easy to install. Flooded lead acid batteries can often be a nightmare in this respect though they do have other benefits that can be useful in their own way. The best battery for solar system would be relatively compact so get something that can obtain and store a lot of energy without taking up too much space.
Efficiency of Power
One thing that a lot of people don’t know is that some solar batteries waste a lot of energy. Lead acid battery can perform reasonably well here, but lithium ion batteries are known for being particularly wasteful. Before you make a purchase, check the power rating of the product. This will help shed some light on how much energy you would actually be able to use and how much would be wasted during the energy delivery process.
If you want a solar battery that lasts ages, you should probably get a deep cycle battery. Because these batteries can be discharged a higher percentage of their total energy storage capacity, the chances of damage occurring is much lower than might have been the case otherwise. Generally, you want a solar battery that lasts at least five years, with ten years being a healthy number and fifteen being indicative of a truly excellent product.
All batteries for solar system have some considerations that need to be made. For example, you should think about how much heat the battery might generate. This would affect where you can place this battery in your home. Price is a factor as well, but it’s not the whole story. How much money the battery will save you in the long run is perhaps more important for obvious reasons. Try to get a balanced view of the product you want to buy before making any final decisions.
Which solar batteries last longest?
Opting for something that has a high percentage discharge would do you well here. While most solar batteries have similar life spans, lithium batteries tend to last longer which is why they are often preferred in spite of their potential environmental drawbacks. They are also quite cost effective when you see how many extra cycles you are getting for the price, so try to take this into consideration as well when looking for solar battery storage.
Are deep cycle batteries good for solar power?
These types of batteries are excellent for a number of reasons. They have a far higher life span, and they are more efficient at distributing energy as well. Another point that people often miss is that they are more durable. By virtue of their design, batteries for solar system that use this type of technology don’t have the same physical limitations. They usually don’t have liquid inside of them which means that they can be placed on their side and moved around without too much trouble. All in all, the combination of benefits you receive from this new technology are hard to ignore. Some people avoid these products because of the additional cost but we think that they are more than worth it when you factor in life expectancy, efficiency, ease of use as well as a lack of maintenance costs.
