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 greater than another?  If so, this report will answer these questions and give you specific things to check on before purchasing your new battery (to make certain you get the most bang for the buck)!

When choosing 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 kinds 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 conclusion of the article you will know exactly how to pick the best battery for your solar panel system!

So let’s get started…

There are three battery types that work exceptionally well; however, each battery type has pros and cons. So the first decision to make is the sort of battery that will fit your system.

Lead Acid Batteries

They’re also one of the longest-used and most dependable batteries in existence.  Compared to the other batteries we will discuss in this report; they’re the cheapest option but you trade cost for some battery life and depth of discharge.  But for homeowners needing lots of storage for a lower cost, or if you are simply making the move to a solar panel system, lead acid batteries might be a very good option.  They’re the sort of battery we use in most of the battery banks within our solar panel systems.

Saltwater Batteries

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

Lithium Batteries

Lithium batteries are the most expensive and the longest lasting of the three types of solar batteries.  Comparing all three choices, 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) Assess the elements of batteries.  As soon as 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 ideal battery to your system.  

Cost

Cost is probably one of the more obvious components.  But the old saying,”you get what you pay for” holds true when buying batteries also.  Sometimes though, certain batteries may be overkill for your system so the most expensive battery might not be the best choice always.

For most systems, a battery will cycle every day, meaning it will drain and charge regularly.  With every cycle, the battery’s ability to hold the identical charge lessens slightly.  So 1 component to consider is the guarantee on the battery that guarantees a certain number of cycles of useful life.  But keep in mind that when you use the maintenance and reconditioning methods we teach you at 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 further 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 compared to a battery with less.

Capacity and Power

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

Efficiency

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

Manufacturer

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