Or have you wondered what makes one deep cycle battery better than another? If so, this report will answer these questions and provide 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 that work best. We will do this in 2 parts:
Part 1) Instantly compare the three main kinds of solar batteries (lead acid, saltwater, and lithium). And,
Part 2) Compare the components of batteries, such as: depth of discharge, power and capacity, efficiency, battery life, and manufacturer.
By the conclusion of the article you will know just how to pick out the ideal battery for 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
Lead acid batteries are the most commonly used rechargeable battery in the world. 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 exchange price for some battery life and depth of discharge. But for homeowners needing a great deal of storage for a lesser cost, or whether you are just making the transfer 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 greater lifespan. Contrary to lead acid batteries, saltwater batteries are basically brand new to the industry and remain both somewhat untested and harder to come across. Of the three types of batteries, saltwater has the best depth of discharge, which means you’ll get 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 options, the lithium ion battery may be the highest rated, but also the most expensive. An 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 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 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 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 daily, meaning it will charge and drain regularly. With every cycle, the battery’s ability to hold the identical charge lessens slightly. So one component to consider is the warranty on the battery which guarantees a certain 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.
Depth of Discharge
Depth of discharge 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 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 save. Power is how much energy a battery can provide at a given moment. A battery with a high capacity and higher power can run a massive system for many hours; a battery with low capacity and higher power can run a large system but only for a short time.
Efficiency is the amount of energy used compared to the amount of energy it took to store energy. Batteries require power to control and efficacy compares the energy taken to control a battery with the amount of energy which the charged battery produces. The higher the efficiency, the more cost-effective the battery.
This might not be a component 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 comes with known flaws and benefits; a startup brand can perhaps have better technology, but can also have yet unknown technological issues. Depending on your system demands, you might decide to go with a well-reviewed firm or one that is brand new to the market.
