How to Pick the Best Nine-Factor Solar Battery

Today Article is about Best Solar Battery we guide you about which is the Best solar battery? How do I choose the correct battery for my solar system?

These are the most common questions I get from clients when sizing their solar system.

We all want the best solar panels available in Pakistan. However, choosing the “best” panel depends on many factors. Stay tuned as we talk about everything related to How to Choose the Best Solar Battery.

First, should I install the battery or not?

Do you require a battery for your solar system?

Whether you need solar depends mainly on your specific circumstances, goals, and priorities.

I have some simple advice.

• Solar panels can significantly benefit you as a backup power source if you live in an area with frequent power outages (load shedding). You will install a hybrid solar power system connected to the grid via net metering and batteries. During outages, these batteries will ensure that essential appliances continue to operate.
• If your utility does not have a net metering program, use batteries. These devices store the excess energy your solar panels produce, preventing it from going to waste. Also, even if they have a net metering program, I would recommend installing batteries if you are not eligible for it. What about the leftover energy your solar panels make each day?
• If you want to install an off-grid system, you will, of course, need batteries. However, sometimes going off-grid becomes necessary, for example, in remote areas with limited grid power.
• If you have no budget concerns and want to get the most out of your system, consider installing solar panels. where you live, then you might not need to spend extra on batteries. You can install an on-grid solar system, which may suit you best. 

Are you still trying to decide? Don’t worry—call us, and we’ll give you more information on whether you need a battery.

But if you decide that you need batteries, then go ahead.

1. Assess your energy needs

First, assess your energy needs. If you are in an area that experiences frequent and prolonged power outages, you will need a good battery backup. This will ensure uninterrupted power during these outages, increasing your overall comfort and safety.

Next, ask yourself a few questions. Do you plan to power your entire home, including all appliances, or are you primarily interested in keeping only essential devices running during power outages? This distinction is crucial in determining the appropriate size for your battery system.

The battery pack should be more significant for those looking to power all their appliances, especially in off-grid scenarios. This ensures a constant power supply, even during cloudy days or extended outages. Off-grid installations require a larger battery capacity to maintain a continuous power flow.

1. Battery type

Once you have determined your energy needs, the next question is what type of solar plates you should choose.

Many types of batteries are available, with different chemistries offering specific advantages and disadvantages.

Lead-acid batteries

Lead-acid batteries have been a tried-and-tested energy storage solution for decades. They’re both cheap and long-lasting. There are two subtypes: flooded lead-acid and sealed lead-acid.

Flooded Lead Acid (FLA) Batteries:  These batteries require regular maintenance, including checking the electrolyte level and adding distilled water. They are economical but have a shorter lifespan than sealed lead acid and lithium-ion batteries.

Sealed Lead Acid (SLA) Batteries: Also known as Valve-Regulated Lead Acid (VRLA) batteries, these are maintenance-free and come in two forms: Absorbed Glass Mat (AGM) and Gel Batteries. Sealed lead acid batteries are less prone to spills and can be installed in a variety of positions. They have a longer life than flooded lead acid batteries but generally have a shorter life than lithium-ion batteries.

Lithium-ion batteries

Lithium-ion batteries have gained popularity in recent years due to their impressive performance characteristics. They are known for their high energy density, longer life, and ability to discharge more deeply without affecting longevity.

• Longer life:  Lithium-ion batteries typically last longer than lead-acid batteries, meaning fewer replacements and long-term cost savings.
• Deeper discharge:  They can be discharged deeper without reducing life and performance, making them a reliable choice for high-power consumers.
• Compact and lightweight:  Lithium-ion batteries are compact and lightweight, making them suitable for small spaces or mobile applications.
• Higher efficiency: They are more efficient in both directions, meaning they use more of the stored energy efficiently.
• Maintenance Free:  Require minimal maintenance, reducing hassle and expense over time.

1. Dimensions and capacity rating

One of the first factors to consider when choosing a solar battery is its size and capacity. This number shows how much electricity the battery can hold. Think of it like the gas tank in your car – it tells you how far you can drive before you need to refuel.

This rating is usually given in kilowatt-hours (kWh) and ampere-hours (Ah).The bigger the battery, the longer it can power your appliances. For home solar systems, we typically use lead-acid batteries that can last for around 5 to 6 hours on a full charge.

Some batteries may have different usable capacities, but you can customize this by connecting multiple batteries if necessary to meet your energy needs.

1. Battery rated power

Power rating refers to the maximum amount of electrical energy a battery can deliver at any given time and is typically measured in kilowatts (kW) or amperes (amps).

Typically, within the nominal power, two categories are distinguished:

1.      Peak Power:  This is the maximum power the battery can deliver for a short period. It’s like a sprinter’s burst of power – a quick, intense burst of power.

2.      Continuous Power Rating:  Measures the amount of power the battery can deliver continuously. Think of it as the battery’s endurance to provide a constant energy flow over time.

For example, if you have power-hungry appliances like air conditioners that require a high power level, you will need a battery with a higher power rating. Generally, a higher power rating battery can quickly provide power to your devices. However, it is essential to note that a higher power rating does not necessarily mean that the battery will stay charged for longer. It is like a powerful but short-term burst of energy.

Now, you may wonder if rated capacity and rated power are the same. They are not.

Here’s a simple way to tell the difference: A battery with a high power rating and low capacity may temporarily keep your appliances running. On the other hand, a battery with a low power rating but high capacity can provide a longer, more consistent power supply, making it suitable for long-term energy needs.

1. Depth of Discharge (DoD)

DoD stands for Depth of Discharge. It basically means how much of the battery’s energy you can safely use without hurting the battery itself. For example, lead-acid batteries used in solar systems usually have a DoD of around 50%. This means you can use about half of the stored energy before you need to recharge it. Using more than half can shorten the battery’s lifespan

Sealed lead acid batteries can reach a 75% discharge level, while lithium-ion batteries can typically be discharged to 90-95%. Because of this, lithium-ion batteries get more use out of their stored energy compared to lead-acid batteries

1. Efficiency of circular motion

For example, if a battery has a 70% efficiency, the remaining 30% of energy is either lost or consumed by the battery’s operating system. You can only use 70% and no more.

Lithium-ion batteries have a higher circular efficiency than lead-acid batteries. To be precise, lead-acid batteries have a 65-80% circular efficiency. In contrast, the efficiency of lithium-ion batteries can reach 95% and not less than 80%.

However, it is essential to note that these figures can vary depending on the lead-acid or lithium-ion battery used, how well it is maintained, and how it is used. Factors such as temperature, depth of discharge, and charge and discharge rates can also affect the battery’s cycle efficiency.

1. Life expectancy

When choosing the Best Solar Battery bank, consider the service life. A battery’s service life refers to how long it can operate effectively before it needs to be replaced. Different types of batteries offer different service lives, which affects their long-term value.

For example, lead acid batteries typically have a lifespan of 3 to 7 years, depending on factors such as maintenance and usage patterns.

In contrast, lithium-ion batteries offer a longer lifespan, typically 10 to 20 years or more, depending on the specific chemistry and usage. Lithium iron phosphate batteries (LiFePO4) are known for their durability and often outperform other lithium-ion options. So, while lithium batteries may cost you more, they are more of a long-term solution.

1. Warranty

Different types of batteries come with different warranty options to provide peace of mind. Lead-acid battery warranties typically last anywhere from half a year to 3 years. Some manufacturers may offer extended warranties, especially for high-quality sealed lead-acid (VRLA) batteries, which can extend the lifespan to 10 years.

On the other hand, lithium-ion batteries typically come with more extended warranties, often spanning 5 to 15 years or more. The exact length can vary depending on the specific chemistry and brand. Due to their high durability, high-quality lithium iron phosphate (LiFePO4) batteries often offer warranties at the higher end of this range.

Also, some warranties extend beyond a fixed term to cover the battery’s performance or lifespan. For example, a warranty may guarantee a certain percentage of the battery’s original capacity for a certain number of cycles (one battery cycle is when the battery is charged and discharged). 

1. Battery cost

The last step in choosing a solar battery is the cost. Based on the above, we all want to buy batteries with high capacity, power, better CR efficiency, higher DoD, and longer life.

But it all comes down to the cost of the battery. The lithium-ion battery is considered the best for working with solar systems but is also expensive. Some of them can cost around PKR 600,000 for a single battery. On the other hand, you can develop a lead-acid battery of comparable size for around PKR 300,000.

Long-term costs should also be considered when calculating costs. For example, lead-acid batteries may seem cheaper at first. But after a few years, they will need to be replaced — after about 15 years, their cost will be almost the same as lithium batteries. So keep that in mind.
