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

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

Part 1)   Quickly 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 manufacturer.

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

So let’s begin…

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

They are also one of the longest-used and most reliable batteries in existence.  Compared to the other batteries we will discuss in this report; they are the cheapest option but you trade price for some battery life and depth of discharge.  But for homeowners needing a great deal of storage for a lesser cost, or if you are simply making the transfer to a solar panel system, lead acid batteries might be an excellent option.  They’re the type of battery we use in most 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 essentially brand new to the industry and stay both somewhat untested and more difficult to come across.  Of the 3 types of batteries, saltwater has the best depth of discharge, so you’ll find the most output per fee 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 battery is probably the highest rated, but also the most expensive.  A good example of a lithium ion battery is the Tesla Powerwall.

Part 2) Assess the elements of batteries.  As soon as you’ve picked the best battery type for your own solar panel or off-grid system (that meets your system’s needs), there are components to research to find the ideal battery for your system.  

Cost

Cost is probably one of the more obvious elements.  But the old saying,”you get what you pay for” holds true when buying batteries also.  Sometimes though, certain batteries could 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 is going to drain and charge regularly.  With each cycle, the battery’s ability to hold the identical charge lessens slightly.  So 1 component to consider is the guarantee on the battery which guarantees a certain number of cycles of useful life.  But bear in mind that if you use the maintenance and reconditioning methods we teach you in 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 down before needing to recharge the battery without damaging its life.  Certain 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 provides more battery power per charge than a battery with less.

Capacity 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 save.   Power is how much energy that a battery can provide at a certain moment.  A battery with both a high capacity and higher 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 short time.

Efficiency

Efficiency is the amount of energy used compared to the quantity 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.  The higher the efficiency, the more cost-effective the battery.

Manufacturer

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