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 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 your 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 two parts:

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

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

By the conclusion of the article you will know just how to pick the best battery to 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 type of battery that will fit your system.

Lead Acid Batteries

They’re also one of the longest-used and most reliable 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 simply making the move to a solar panel system, lead acid batteries might be an excellent option.  They’re the type of battery we use in the majority of the battery banks in 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 remain both somewhat untested and more difficult to come across.  Of the three types of batteries, saltwater has the greatest depth of discharge, so you’ll get 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.  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 may be the highest rated, but also the most expensive.  A good example of a lithium ion battery is the Tesla Powerwall.

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

Cost

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

For many systems, a battery will cycle daily, meaning it is going to drain and charge 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 specific number of cycles of useful life.  But bear in mind that when 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 may be depleted further 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 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 massive system for many hours; a battery with low capacity and high power can run a large system but just for a brief time.

Efficiency

Efficiency is the amount of energy used compared to the amount of energy it took to store said energy.  Batteries require power to control and efficiency compares the energy taken to control a battery together with the amount of energy that the charged battery generates. 

Manufacturer

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