In this article, we will discuss how to pick the best battery for a home solar panel system. so you are looking for batteries for your off-grid energy set up and you're wondering which batteries perform the best. which ones last the longest how do I get the best view out there in the market and which kind of battery should really look out for or not Buy well? In this article, I will give you a few basic principles that you can use to compare any kind of battery that you're looking at aside. On a side basis, before we go ahead let me introduce myself my name is Keyani I'm a renewable energy engineer. I'm specialized in off-grid battery-based solar energy systems in the design and installation of off-grid solar energy systems.
I founded the company sold a solution through which I provide articles such as this. I share my knowledge and experience through articles and I provide personal direct support through services on my website. So let's get started, I'll keep this article fairly short and I'll divide it into only two sections. First the section we'll look at the actual capacity of the battery so what kind of consequence does it have when you're looking at two-volt six-volt 12-volt batteries. What does it actually means the M power rating of the water or a kilowatt-hour rating? And last but not least what about the discharge rating the EC rate etc. what does it all mean in the second section we'll look at what kind of life.
Lead Acid Batteries
You can actually expect certain batteries to look at the depth of discharge figures and how you can use this to your advantage and of course the cycles. What does it mean? what kind of cycles are you looking for? and how does it affect the lifetime of your battery? So let's start by looking at the capacity of the batteries. I want to mention something about the voltages so the typical voltages that you can find out, there are 2 volt 6 volt and 12 volts. The main reason why at different voltages is because they're all built of individual battery cells. One battery cell existing of let play submerge into electrolyte creates. 2 volts you combine three cells in series you make six volts. You can bind six cells in series, you make it 12-volt battery.
Saltwater Batteries
So that's the basic difference between these batteries. So the other figure of How to pick the best battery for a home solar panel system. I want to mention is the M power rating of a battery. So the M power rating indicates the number of amps the amount of electricity that can withdraw from a battery during the amount of time. So for example, if a battery has a hundred amp-hours the rate, you can withdraw a hundred amps during one hour and it will be empty or you withdraw ten amps during ten hours and then it will be empty.
So that is the empower rating and it's a very important number for a battery. Now the other value closely related to the M power rating is the C rate or the discharge rate. So what is important for you to understand is that if you would empty a battery in a small amount of time then the total amount of energy that would you be able to get out of the battery is less. And if you take the same battery but empty it over a longer amount of time it quickly low energy. Empty it slowly more energy so the C rate indicates the amount of Empowered amount of energy that you can withdraw out of the battery. If you completely emptied the battery in a certain amount of time so a C rate of C- indicates the amount of empowers.
What happens when your solar batteries start to die?
what this means if you have established that you're using half of your battery's capacity on a typical day 50% depth of discharge. For example, a thousand cycles then if you would discharge and charge your battery once a day to $0.50 you can do this a thousand days in a row before you reach the end of the lifetime of the battery. But if you discharge to 50% and charge it back up and do this twice a day you can do it for 500 days in a row before you reach the end of the lifetime of the battery. But now here's an interesting thing for you to remember the battery industry worked with this term, battery end-of-life time but what does it actually mean.
Well, they
consider that a battery has reached is end-of-life time when the usable capacity
of the battery has been reduced by 20%. So now a question for you if there's something else that you'd like to learn more about let me know in the comments
below and I use this as inspiration to provide more articles for you. If you like the article is always nice to hear so give me a thumbs up.
Conclusion: In the end, we conclude that how you can pick the best battery for a home solar panel system by using the above methods. So keep all my important points in your mind while buying solar panels for your home. So that's is all for now and I'll see you in the next article.
Cheers
