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 buying your new battery (to make certain you get the most bang for the buck)!
When picking a battery (or batteries) for your solar panel system, there are 3 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 components of batteries, such as: depth of discharge, capacity and power, efficiency, battery life, and manufacturer.
By the end of the article you will know exactly how to pick the best battery to your solar panel system!
So let’s get started…
Part 1) The Three Best Types Of Batteries For Solar Panel Systems: The best type of battery for your solar panel system will be dependent 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
They are also one of the longest-used and most dependable batteries in existence. When compared with the other batteries we’ll discuss in this report; they’re the cheapest option but you trade price for some battery life and depth of discharge. But for homeowners needing lots of storage for a lesser cost, or whether you are simply making the move to a solar panel system, lead acid batteries may be an excellent option. They’re the type of battery we use in most 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 essentially brand new to the market and stay 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 fee before needing to recharge.
Lithium batteries are the most expensive and the longest lasting of the three kinds of solar batteries. Comparing all three choices, the lithium ion battery may be the highest rated, but also the most expensive. An example of a lithium ion battery is the Tesla Powerwall.
Part 2) Compare the components of batteries. Once you’ve chosen the best battery type for your solar panel or off-grid system (that meets your system’s needs), there are elements to research to find the ideal battery to your system.
Price is probably one of the more obvious components. But the old saying,”you get what you pay for” holds true when purchasing batteries also. In some instances though, certain batteries could be overkill for your system so the most expensive battery may not be the ideal choice always.
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 hold the identical charge lessens slightly. So one component to consider is the guarantee on the battery that 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 at the EZ Battery Reconditioning program, you can extend the life of your batteries.
Depth of Discharge
Length of release is how much you can drain the battery down before needing to recharge the battery without damaging its life. Particular 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 compared to a battery with less.
Ability and Power
The more capacity a battery has, the more power it can store. Power is how much energy that a battery can provide at a certain moment. A battery with a high capacity and higher power can run a large system for many hours; a battery with low capacity and higher power can run a large system but just for a short time.
Efficiency is the amount of energy used compared to the quantity of energy it took to store said energy. Batteries require power to charge and efficacy compares the energy taken to charge a battery together with the amount of energy that the charged battery generates.
This may not be a part most would consider, but it’s something to focus on. Like other technology, there are both reputable brands and startup brands. A trusted brand includes known flaws and advantages; a startup brand can perhaps have better technology, but can also have unknown technological difficulties. Based upon your system needs, you may decide to go for a well-reviewed company or one that is brand new to the market.
