Or have you wondered what makes one deep cycle battery greater than another? If so, this report 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 picking a battery (or batteries) for your solar panel system, there are three categories of batteries which work best. We will do this in two parts:
Part 1) Instantly compare the three chief 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 end of the article you will know exactly how to pick the ideal battery to your own solar panel system!
So let’s get started…
So the first decision to make is the sort of battery that will fit your system.
Lead Acid Batteries
They’re also one of the longest-used and most dependable batteries in existence. Compared to the other batteries we will 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 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 may be a very good option. They’re the type of battery we use in the majority of the battery banks in our solar panel systems.
Saltwater batteries are more expensive than lead acid batteries, but also have a greater lifespan. Unlike lead acid batteries, saltwater batteries are essentially brand new to the market and stay both somewhat untested and harder to come across. Of the 3 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 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 ion battery is probably the highest rated, but also the most expensive. An example of a lithium battery is the Tesla Powerwall.
Part 2) Compare the components of batteries. As soon as you’ve chosen 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.
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 may be overkill for your system so the most expensive battery might not be the ideal choice always.
For most 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 one component to consider is the guarantee on the battery which guarantees a certain number of cycles of useful life. But keep 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 damaging its life. Certain 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.
Capacity 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 high power can run a large system for several hours; a battery with low capacity and high power can run a large system but only for a brief time.
Efficiency is the amount of energy used compared to the quantity of energy it took to store energy. Batteries require power to charge and efficiency compares the energy taken to control a battery with the amount of energy that the charged battery produces. The higher the efficiency, the more cost-effective the battery.
This may not be a part most would consider, but it is something to focus on. As with other technology, there are both reputable brands and start-up brands. A trusted brand includes known defects and benefits; a start-up 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 firm or one that is brand new to the market.
