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

Have you ever wondered how to pick out the best battery(s) for your solar panel system (or off-grid energy 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 make certain you get the most bang for the buck)!

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

Part 1)   Quickly compare the three main types 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 exactly how to pick the ideal battery to your 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 sort of battery that will fit your system.

Lead acid batteries are the most commonly used rechargeable battery in the world. They are also among 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 lesser price, or whether you are simply 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 within our solar panel systems.

Saltwater batteries are more expensive than lead acid batteries, but also have a better lifespan.  Contrary to lead acid batteries, saltwater batteries are basically brand new to the industry and remain both somewhat untested and more difficult to come across.  Of the 3 types of batteries, saltwater has the greatest 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 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.  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 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 buying batteries as well.  In some instances though, certain batteries may be overkill for your system so the most expensive battery may not be the ideal choice always.

Battery Life and Warranty

For most 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 same charge lessens slightly.  So one component to consider is the warranty on the battery which 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 program, you can extend the life of your batteries.

Length of Discharge

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

Capacity 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 given 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 operate 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 save energy.  Batteries require power to control and efficacy compares the energy taken to charge a battery 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 technologies, there are both trusted brands and startup brands.  A trusted brand comes with known defects and benefits; a start-up brand can perhaps have better technology, but can 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.
