Buying Guide for the Best Batteries for Solar Lights

Solar lights are quite popular these days since they are quite easy to use and offer a great way of using green power at your home. But if you want to use these solar lights, you will need to have a battery installed along with it.

If you want to know more, we are here with a buying guide just for you. You can essentially consider the following points to buy the best batteries for solar lights:

Capacity

As you would know, the batteries of your solar light are there to make sure that it keeps working even at the night. But if you want to ensure that it can last throughout the night without running out, checking the capacity of your batteries becomes quite important.

This capacity rating is given in mAh and includes various ratings like 600 mAh, 1200 mAh, and even 2800 mAh depending on the batteries that you get. Out of all these options, the 2800 mAh battery capacity rating is the highest which will result in a pretty long battery life.

Number of Batteries

Those of you who are going to install solar lights around their home are most likely going to be using multiple lights. Because of this, you will need a lot of batteries since each light itself will also require multiple batteries.

As a result, all batteries for solar lights available out there come in a pack of multiple batteries. This includes different pack sizes like 6 batteries, 8 batteries, 12 batteries, 16 batteries, and even 20 batteries. And just as you would expect, a larger pack size of 20 batteries or so will result in a high value for money.

Warranty

The first thing to check to ensure this is to check the number of charge cycles offered by them. While some come with 500 charge cycles, others might offer 1000 charge cycles for better longevity.

Although, the most important thing to consider while buying reliable batteries for your solar lights is the included warranty. While some of them might offer a 1 year or a 2-year warranty, there are a few batteries out there that also offer a 3-year warranty for better longevity and your peace of mind.

How do solar batteries work?

Typically, with a solar panel system, you export the excess solar energy you produce back to the grid, and the utility pays you for it – this is called “net metering.” Additionally, during a power outage, most standard solar systems cannot work – the National Electric Code prohibits it. However, a battery can store your excess energy, and provide that power both during the night (when the system is not producing) and during an outage.

There are multiple advantages to this. First, the comfort of having power in an outage cannot be overstated. Secondly, in areas where the utility charges more for peak hours or does not offer “net metering,” having the battery store your solar energy can be a massive financial boon.

There are multiple batteries available on the market. By far the most powerful energy storage solution is the Tesla Powerwall, which holds 13.5 kWh of power – this is enough to power the full usage of a family for a full 24 hours.

New Advances in Solar Batteries

Solar batteries like Tesla Powerwall have made great advancements. Such battery systems provide seamless backup power during utility outages. In certain instances, you can even run your home from solar and Powerwall indefinitely. Another feature that seems to be going around is that you can monitor your home energy. This way you get to keep track of your solar, Powerwall, and home energy in real time on your mobile app.

Energy storage is quite a young industry, and there are many states and municipalities that encourage the installation of these solar batteries. For example, Ohio used solar and storage to expand for its municipal utility. It was confirmed that the benefits projected for the utility exceeded expected projection in the first 18 months.

If you’re interested in a quote on a Tesla Powerwall or battery, let us know! 2019 is a great time to get a battery due to the 30% federal tax credit still available. Make a sound investment with solar panels in Chicago and anywhere else in the United States!

1. How Do Solar Batteries Work?

Types of Inverter Batteries And Their Various Pros & Cons

Since solar panels only produce electricity during the day, they cannot power night-time electricity usage on their own. Thus, many homeowners simply use grid energy at night – though they still pay lower electricity bills overall, since feed-in tariffs credit solar houses with all the extra electricity their panels fed into the grid during the day.

Other homeowners prefer to keep their solar electricity for their own use, so they connect their solar systems to storage batteries. These batteries store solar energy generated throughout the day, so that homeowners can take advantage of free electricity at any time of the day or night:

Are you not able to deal with the unbearable summers and numerous power cuts in your region? Time to buy an efficient and robust inverter and inverter battery for your worry-free summers. Talking about just the battery, a battery is a vital part of an inverter. The performance and life of an inverter largely depend on its battery.

Although there are many brands available in the market, it is important to know the various types of inverter batteries and their pros and cons. The various classifications of inverter batteries are:

  • Lead-acid batteries: These are the most common types of inverter batteries used. They are one of the oldest types of rechargeable batteries. The lead-acid batteries consist of two electrodes dipped in the electrolyte solution. The electrodes are lead and lead dioxide, hence the name lead-acid batteries. These two electrodes immersed in sulphuric acid causes the chemical reactions that generate DC current.

Their main positive features are:

o Rechargeable
o Lightweight
o Economical
o Produces a large amount of current

Some of their cons are:

o Needs regular maintenance
o Need water toppings regularly
o Releases harmful gases during charging and discharging
o Needs regular electrolyte check

  • Maintenance-free batteries: As the name suggests, they are sealed batteries that overcomes certain drawbacks of lead-acid batteries. The electrolyte inside it is completely absorbed in the separator and does not require water to be added. The most significant benefit of the sealed design is that no service attention is required, other than just keeping the battery clean and fully charged. Maintenance-free batteries tend to lose electrolyte at a much slower rate than maintenance models.

The positives are:

o Do not require electrolyte check
o No need for water toppings
o Safer
o No maintenance needs
o Faster charging
o No battery emissions
o Can be placed in any orientation

Like its counterpart, they also have few drawbacks, such as:

o Costly
o Have a shorter life

  • Tubular batteries: They are the most efficient inverter batteries and are quite popular as well. The pencil-type armoured tubular plates are designed for uninterrupted power delivery in case of long power cuts. The tubular inverter battery for home comes in abrasion-resistance, leak-proof tower type, which ensures lower maintenance and better safety. These batteries are safe for the environment, and their efficient working makes them an ideal buy for the homes.

Their positives are:

o Great efficiency
o Highly reliable
o Longer operational life
o Low maintenance
o Suitable for heavy-duty applications and frequent power cuts

Negatives are:

o Complex design
o Costly

It is always advisable to go for branded inverters and batteries to ensure a great performance, and warranty span. Local batteries have many downsides like poor efficiency, less safe, poor operational life and high maintenance. Also, they affect the performance of the inverter as well. So, don’t kill your inverter as well the smooth working of your household by going for non-branded inverter batteries.

Livguard is amongst one of the best inverter battery manufacturers in India. Our batteries are well designed to suit the needs of all appliances. It’s efficient performance and robust design lessens the worry of a continuous power supply in case of long power cuts.

Different Types Of Solar Batteries

Before we do anything else here, we want to help you understand what to look for when choosing a solar battery. A part of this is knowing the differences between the varying kinds of batteries to use. Let’s take a look at the 4 types of solar batteries that you can use for your solar panel system.

Flooded Lead Acid Battery

Trojan T-145 6V 260Ah Flooded Lead Acid Golf Cart Battery

The flooded lead acid battery is one of the most common ones used for off-grid setups. These batteries are also known as wet cell batteries.

Some of the benefits associated with these batteries are that they have a fairly low upfront cost, they are quite safe, and fairly reliable too.

When it comes to drawbacks, flood lead acid batteries tend to be very large and take up a lot of space, plus they also tend to suffer from corrosion. 

This type of battery needs a fair bit of maintenance and monitoring, as they need to be kept in a well-ventilated environment, and they need to be kept upright to prevent leaking. If you don’t mind some regular maintenance and monitoring, this is one of the best options to go with, but if you don’t want to engage in regular monitoring, the AGM battery may be a better choice for you.  Trojan is one of the few well-known brand that still carry flooded lead acid batteries. 

AGM (Sealed Lead Acid) Battery

The next type of battery to go with is the AGM battery, which stands for Absorbent Glass Matt. This is a type of lead acid battery, but one where the electrolytes are absorbed into a glass matt. The plates in an AGM battery can be flat or they can be wound into a spiral.

One of the advantages is that this type has a lower internal resistance than flood lead batteries, plus they are better at handling temperatures, and they do not discharge as slowly as some other battery types.

Mighty Max Battery 12V 100AH Battery for Solar System

Other advantages include that AGM batteries hold static charges for a long time, they are not inclined to heat up, they can handle the cold quite well, they are lightweight, and non-hazardous too. They also do not require as much maintenance as flood lead batteries. With that being said, they come with quite a hefty price tag.

Gel Batteries


Mighty Max 12V 35Ah Gel Type Battery

Most people probably won’t go with gel batteries, as they have more drawbacks than most of the other options, and their advantages are fairly minor when compared to other battery types. Gel batteries used fumed silica to thicken the electrolyte, which makes these cells sturdier. What is also convenient is that the viscous nature of the electrolyte prevents leaking when damage occurs.

Other advantages of the gel battery are that it does not require much maintenance at all, and they are quite durable, as well as resistant to shock and vibration. Moreover, they are great both for extreme heat and cold, plus they have excellent life cycles.

With that being said, gel batteries have narrow charging profiles and it is not hard to damage them through improper or over charging. These also don’t have the greatest amp-hour capacity, but they still cost quite a bit.

Lithium-Ion Battery (LiFePO4)

When it comes to the best in solar batteries, lithium-ion batteries are definitely up there. To get the disadvantage out of the way, they are expensive, up to 4 times as expensive as any other solar battery. However, they do have great performance.

For one, their capacity and life cycle, when compared to their very small and lightweight design, is very good. You can check out this large capacity 12V 170Ah Lithium-ion battery from Renogy on Amazon.

Renogy Lithium-Ion Phosphate Battery 12V 170Ah 

They have great efficiency and really long lifespans and are also very safe and stable; they barely require any maintenance, and don’t require any attention for at least 15 years after installation.

They also do not lose as much capacity as other batteries when they are idle. All in all, for more or less every single reason, lithium ion batteries are the best, but they are also by far the most expensive ones to go with.

Things To Consider When Choosing a Solar Battery

You don’t want to just run out and buy any solar battery. There are some considerations you should keep in mind before making a purchase, so let’s talk about these right now.

1. Battery Capacity

One of the most important things to consider before buying any solar battery is how big it is. Here we are not really referring to physical size, although this is another consideration you might want to keep in mind based on your own spatial requirements. However, by size, what is meant is how much energy the battery in question can store.

what-is-amp-hour

Battery capacity is typically measured in unit of Amp-Hour (Ah), it states the amount of energy that a battery can hold under specified conditions. For instance, a 12 volt 18 Ah battery can delivery one hour of 18 ampere of current at 12 volt.

Keep in mind that if you get stackable batteries, you can use multiple batteries at once. One thing to think about is that a battery with a low capacity and high power rating can run your whole home, but for just a few hours, whereas one with a high capacity and low power rating can only power a few important appliances, but for a long time. Generally speaking, the higher the capacity and the higher the power rating, the better off you are.

2. Charging Time

If you are worried about how much sun and time it takes to charge the solar battery in question, you are probably best off going with gel, as they charge really fast. Lithium-ion batteries also do not take long to charge, usually around 3 hours or so, maybe a bit longer.

Flooded lead acid batteries can take up to a whole day to charge, if not longer. Of course, the faster the battery charges, the better off you are because it doesn’t take as much light or time for charging, and you can get to using that solar power much faster too.

3. Ease of Installation

Something else to keep in mind before you go out and buy a solar battery is how easy the one in question is to install. Now, while this isn’t rocket science, it is also not something you want to do if you haven’t dealt with a solar panel system before.

When it comes down to it, you will most likely want the help of a professional for this. Although, with that being said, if you want something that is space friendly, maintenance free, and relatively easy to install, you might want to go with a lithium-ion battery.

4. Your Budget 

Of course, the upfront cost for the solar battery itself is something else you should keep in mind. One thing we want to note here is an old adage – you get what you pay for. Generally speaking, the more expensive the solar battery, the better it will perform and the longer it will last.

Something like a lithium-ion battery might cost many times the amount of an AGM or lead flood acid battery, but it also requires much less maintenance, is more resilient, easier to install, and features better overall performance in pretty much every way.

5. Battery Lifespan

Another important consideration is how long the battery will last. Keep in mind that as the days go on, your battery will have less of an ability to hold a charge. Each battery you can buy will come with a certain number of hours, days, and years that it can be used until it becomes more or less useless and can no longer hold a charge well.

This will depend on the type of battery, the size, and the brand name, but generally speaking, the longer you want it to last, the more you will have to pay. You always want to pay attention to the rating on the packaging in regards to this.

6. Manufacturer’s Warranty

The other really important thing you want to look for is how good the manufacturer’s warranty for the battery is. Of course, you don’t want to spend thousands on one of these batteries, only to have it break in a few years, just to learn that it is not covered under warranty anymore.

Of course, the more you spend on your battery, and the more reputable the brand name is, the better this warranty will be. When it comes down to it, a 20- or 30-year warranty is great, a 10-year warranty not so much, and of course, the lifetime warranty is always best.

Solar Battery Maintenance

The type of maintenance required for a solar battery depends on the battery type.

Flooded lead-acid batteries contain a liquid electrolyte and are the most prone to corrosion and require the most maintenance. Using a sealant like petroleum jelly on all terminals significantly reduces corrosion.

Washing the top of batteries helps remove dust which can lead to a small amount of energy loss between the terminals. Be sure to locate the batteries where you can easily wash them.

Batteries deteriorate more quickly when the temperature fluctuates to extremes. The best place for solar batteries is an insulated location where the temperature stays as close as possible to 77ºF (25ºC).

You can also reduce the need for solar battery maintenance by installing more batteries in series and increasing the overall capacity of your system.

The Best Solar Batteries for Your Home

Solar replacement battery systems come in many shapes and sizes from small Duracell solar batteries for charging a mini solar battery for outdoor landscaping to medium-sized flooded lead-acid batteries ideal for off-grid locations to large lithium batteries for powering a big house with high energy needs.

Which of the top 10 batteries are best for your home depends on your specific electrical needs, how willing you are to do maintenance on batteries, and your budget for upgrading your solar energy system.
