Or have you wondered what makes one deep cycle battery greater than another?  If so, this article will answer these questions and give you specific things to check on before buying your new battery (to make certain you get the most bang for the buck)!

When picking a battery (or batteries) to your solar panel system, there are three categories of batteries which work best.    We’ll do this in 2 parts:

Part 1)   Instantly compare the three chief types of solar batteries (lead acid, saltwater, and lithium).   And,

Part 2)   Compare the elements of batteries, such as: depth of discharge, capacity and power, efficiency, battery life, and maker.

By the end of this article you will know just how to pick out the best battery to your own solar panel system!

So let’s begin…

Part 1) The Three Best Types Of Batteries For Solar Panel Systems: The best type of battery for your solar panel system will depend on what you’re looking for. So the first decision to make is the type of battery that will fit your system.

Lead acid batteries are the most commonly used rechargeable battery in the world. They’re also among the longest-used and most reliable batteries in existence.  When compared with the other batteries we will discuss in this report; they’re the cheapest option but you exchange price for some battery life and depth of discharge.  But for homeowners needing lots of storage for a lower price, or if you are just making the transfer to a solar panel system, lead acid batteries might be a very good option.  They’re the type of battery we use in the majority of the battery banks in our solar panel systems.

Saltwater batteries are more expensive than lead acid batteries, but also have a better lifespan.  Unlike lead acid batteries, saltwater batteries are basically brand new to the industry and stay both somewhat untested and more difficult to come across.  Of the three kinds of batteries, saltwater has the best depth of discharge, which means you’ll find the most output per charge before needing to recharge.

Lithium batteries are the most expensive and the longest lasting of the three kinds of solar batteries.  Their depth of discharge is less than that of a saltwater battery, but more than that of a lead acid battery. Comparing all three choices, the lithium ion battery may be the highest rated, but also the most expensive.  A good example of a lithium battery is the Tesla Powerwall.

Part 2) Compare the elements of batteries.  Once you’ve chosen the best battery type for your solar panel or off-grid system (that meets your system’s needs), there are components to research to find the perfect battery for your system.  

Cost

Price is probably one of the more obvious components.  But the old saying,”you get what you pay for” holds true when purchasing batteries as well.  In some instances though, certain batteries may be overkill for your system so the most expensive battery may not be the best choice always.

Battery Life and Warranty

For many systems, a battery will cycle every day, meaning it is going to charge and drain regularly.  With each cycle, the battery’s ability to maintain the identical charge lessens slightly.  So one component to consider is the warranty on the battery that guarantees a certain number of cycles of useful life.  But keep in mind that if you use the maintenance and reconditioning methods we teach you at the EZ Battery Reconditioning application, you can extend the life of your batteries.

Length of Discharge

Length of release is how much you can drain the battery before needing to recharge the battery without damaging its life.  Particular solar batteries can be depleted farther than others, allowing for more use between charging.  Essentially, a battery with a 90% depth of discharge per cycle will provide more battery power per charge compared to a battery with less.

Ability and Power

The more capacity a battery has, the more power it can save.   Power is how much energy that a battery can provide at a certain moment.  A battery with a high capacity and high power can run a large system for several hours; a battery with low capacity and higher power can run a large system but just for a brief time.

Efficiency

Efficiency is the amount of energy used compared to the quantity of energy it took to store energy.  Batteries require power to control and efficacy compares the energy taken to charge a battery together with the amount of energy that the charged battery generates.  The higher the efficiency, the more cost-effective the battery.

Manufacturer

This might not be a component most would consider, but it’s something to focus on.  As with other technologies, there are both reputable brands and start-up brands.  A trusted brand includes known flaws and advantages; a startup brand can perhaps have better technology, but could also have unknown technological difficulties.  Depending upon your system needs, you might decide to go with a well-reviewed company or one that is brand new to the market.
