Why choose ESE for your Solar Battery Storage

With the rising climate crisis and cost of energy, solar power has become more popular than ever. People all over the world are installing panels so that they can harness the power of the sun. However, once the sun sets, you won’t be able to rely on the panels any longer. That’s why many people make use of solar batteries – which can be added to an existing solar panel system.

A solar battery storage system can store energy and make a tremendous difference when it comes to the efficiency of the system. An energy storage system completely changes how much energy is available to you, and a home battery storage system really increases the usable capacity for your family. So, if you want to make your solar panels more energy efficient, then solar battery storage might be for you…

Some of our most popular battery products available to you

Solar Battery Overview

Solar panels can only generate power while the sun is out. That means you won’t be able to produce any energy at night.

That’s where solar batteries come into play. A battery system is able to store energy from the panels in the morning. Then, once the sun sets, your battery storage systems can release the power when needed. This allows people to use solar energy even when it’s pitch black outside, making their energy usage more effective, too.

Solar battery storage systems have been around for quite a while. Yet, their popularity has rocketed in the past few years. That’s because the need for sustainable energy grows by the day, and solar panel battery storage is becoming more essential if you want to get the most out of having solar panels installed at home or work.

Solar Battery Types

There are a few different types of solar batteries that are suitable for your solar panels. Each one has specific advantages and disadvantages.


One of the most common solar batteries for solar panel systems is the lead-acid variety. This device has been around for decades and is popular in industrial applications.

A lead-acid solar storage battery is reliable and doesn’t require that much maintenance. That makes them incredibly easy to use for a long time. On top of that, this solar battery system is cost-effective. This means you won’t need to break the bank to install the home solar setup.

Sadly, lead-acid batteries have a low energy density. So, they won’t be able to hold much energy per kilogram of weight – making their energy storage capabilities a little disappointing. However, lead acid batteries still remain one of the more popular batteries installed in a battery storage system because its stored energy is still impressive, it just means the batteries are a little larger.


The operation of flow batteries depends on chemical reactions. Inside the storage container, you’ll find electrolytes flowing between two chambers. One of the best features of these devices is that they have a high depth of discharge (DOD). That means they should be able to release most of their stored capacity and provide a more efficient power transfer. Because of that, they offer an incredibly efficient operation.

The only drawback is that flow batteries have a low energy density. You’ll need a massive chamber to store enough energy to power your home. Plus, they can be expensive, making them an impractical option for small spaces.


Lithium-ion batteries have only been around for a few years. Yet, lithium batteries have had a major impact on the power storage market. These devices have an exceptionally high energy density. That means even small batteries can hold a sizable amount of power – and smaller battery systems are much more convenient for homeowners.

While lithium-ion batteries have many advantages, they also come with a few drawbacks. For starters, these are the most expensive options on our list, and a solar PV system can already be expensive enough, so adding expensive solar battery storage can feel overwhelming. Besides that, the devices are tricky to install. When set up incorrectly, the batteries can catch fire because of thermal runaway.

Thankfully, ESE Solar are experts at installing solar panels and battery systems, so you can rely on us to make your solar batteries work in a safe and reliable way.


Nickel-cadmium batteries are arguably the most durable variety on our list. They don’t require much maintenance and can handle extreme temperatures, meaning green energy from your solar panels year-round, without risk of downtime due to issues with your solar battery storage.

On top of that, they have a higher energy density than lead-acid batteries. That means the nickel-cadmium variety is more efficient and cost-effective. This makes them ideal for industrial applications. Yet, since cadmium is toxic, the batteries aren’t all that suitable for a home installation.

Solar Battery Advantages

Use More Renewable Energy

Solar panels can only generate power during the day. Once the sun sets, the energy in the panels will dissipate even if you don’t use it. That means you’ll waste some solar energy, and will have to pull energy from the national grid. So installing one of our batteries can help you avoid this issue.

Since you’ll be able to store excess solar power, you won’t need to rely on the grid as much. This, in turn, should reduce your overall carbon emissions.

Gives You Energy Independence

When the power goes out, all the solar panels in the area will stop working. That’s in an effort to prevent feedback to the grid. However, that means you won’t have access to any solar energy. Thankfully, with a battery that’s going to change. Since the panels have a location to send excess power, they’ll keep running through blackouts.

Provides You With Quiet Operation

Many of us are familiar with conventional gas generators. These are devices that can supply extra power to your house in case of a blackout. While these generators are reliable, they have many drawbacks. Not only do they rely on fossil fuels to operate, but they can also be incredibly noisy. They’ll grunt and hum as long as they’re running and this can be a major nuisance if your area experiences frequent blackouts.

Luckily, with solar battery storage, you won’t have to deal with this issue. The devices are exceptionally quiet and you can have them running in the background all day and night.

Helps You Save on Energy Bills

Since you won’t have to rely on the grid as much, you can save money on energy bills. You can choose to use the power in the batteries to reduce your dependence on utility providers. A larger battery capacity means more savings on your electricity bills.

Besides that, if your panels generate excess energy, you can sell that power back to the grid. Although this will depend on the net metering system you follow.

Solar Battery Disadvantages

Has a Limited Capacity

With solar energy, you don’t get to decide how much power you store. The levels of sunlight will determine the amount of electricity the panels generate. That means you’ll only have a limited supply of power. Even with plenty of sunshine, the batteries can only hold so much energy. Because of that, you’ll waste some of the solar power you produce.

To increase the capacity, you’ll either need more batteries, or larger devices. Both solutions aren’t ideal. More batteries will mean the solar setup is more complex. As for the large storage containers, they’ll be tricky to move around and install. Finding the perfect energy storage system can be hard work when you install solar panels, a battery and panel inverters on top!

Requires Regular Maintenance

Solar power systems can operate for a long time, some even last for over 10 years. Although, for that to happen, the setup will need constant maintenance. That includes monitoring battery charge levels, regular check-ups, and replacing batteries. These all seem simple enough, but after a while, the process can become tedious.

You can call in a professional to take care of the maintenance. ESE Solar provides a maintenance package for your solar panel and solar battery storage system – meaning your entire solar installation can be cared for effectively, from solar PV panels to your DC battery systems.

Tricky to Install

When adding batteries to your solar power system, you have to be careful with the setup. The devices are a bit finicky and can pose a safety threat. That’s because the batteries can overheat quite easily. You need to ensure that the energy stores have the correct ventilation.

Ignoring this factor may cause the devices to deteriorate rapidly. Other than that, if you don’t install them properly, or the outer casing gets damaged, then they can catch fire. This can be a major health hazard and may lead to serious injury. With expert installers like ESE, we can ensure your solar battery is fitted to new or existing solar PV systems without issue!

Can Be Expensive

One of the most notable disadvantages of solar batteries is the cost. If you factor in the price of the solar battery and the installation, the service can be pretty pricey. This high initial solar battery cost makes setting up a solar power system a bit tricky. That’s because the expenses may outweigh any potential savings on energy bills. On top of that, the batteries don’t last forever. That means you’ll have to replace them every so often.

For that reason, relying on solar energy may prove to be more expensive than using the grid in some circumstances. Contact us for a solar quote today, and we’ll look closer at whether a solar panel and battery system will work for you.
