How To Pick Out The Best Battery For a Solar Panel System, Battery Bank, or Off-Grid System

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

When choosing a battery (or batteries) for your solar panel system, there are 3 categories of batteries that work best.    We’ll do this in two parts:

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

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

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

So let’s get started…

So the first decision to make is the sort of battery that will fit your system.

They’re also among the longest-used and most dependable batteries in existence.  When compared with the other batteries we will discuss in this report; they are the cheapest option but you exchange cost for some battery life and depth of discharge.  But for homeowners needing a great deal of storage for a lower price, or if you are just making the move to a solar panel system, lead acid batteries might be an excellent option.  They’re the sort 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 greater lifespan.  Unlike lead acid batteries, saltwater batteries are essentially brand new to the market and stay both somewhat untested and harder to come across.  Of the 3 types of batteries, saltwater has the greatest depth of discharge, which means you’ll get the most output per fee before needing to recharge.

Lithium batteries are the most expensive and the longest lasting of the three types 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 options, the lithium battery is probably the highest rated, but also the most expensive.  A good example of a lithium battery is the Tesla Powerwall.

Part 2) Compare the components of batteries.  Once you’ve chosen the best battery type for your own solar panel or off-grid system (that meets your system’s needs), there are components to explore to find the perfect battery to 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.  Sometimes though, certain batteries may be overkill for your system so the most expensive battery might not be the ideal choice always.

For many systems, a battery will cycle every day, meaning it will charge and drain regularly.  With every cycle, the battery’s ability to hold the identical charge lessens slightly.  So 1 component to consider is the warranty on the battery which guarantees a specific number of cycles of useful life.  But keep in mind that when you use the maintenance and reconditioning methods we teach you in the EZ Battery Reconditioning program, 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.  Certain solar batteries may be depleted farther than others, allowing for more use between charging.  Essentially, a battery with a 90% depth of discharge per cycle provides more battery power per charge than a battery with less.

Ability and Power

Measured in kilowatt hours (kWh), capacity is the amount of energy a battery can store over time. The more capacity a battery has, the more power it can store.   Power is how much energy that a battery can provide at a given moment.  A battery with both a high capacity and high power can run a large system for several hours; a battery with low capacity and high power can run a large system but only for a short 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 efficiency compares the energy taken to control a battery with the amount of energy which the charged battery produces. 

Manufacturer

This might not be a part most would consider, but it is something to focus on.  As with other technologies, there are both trusted brands and start-up brands.  A trusted brand includes known flaws and benefits; a start-up brand can perhaps have better technology, but could also have yet unknown technological issues.  Based on your system demands, you may decide to go with a well-reviewed firm or one that is brand new to the market.
