Wondering what a home battery is, and how it can revolutionize the way you use energy in your home? You&#;re in the right spot. Not only is Swell Energy all about hooking people up with their own, battery-fueled energy fortress, but we love telling people about home batteries, and why no home energy system is complete without them.
In short, a home battery is an in-home energy storage unit that has the ability to store energy either straight from the power grid, or power generated from renewable energy resources like wind and solar. Households can install single batteries, or couple them together for even more storage capacity. Using lithium-ion technology, home batteries charge and discharge just like any rechargeable battery, only on a much larger scale. You can use a home battery to power most anything in your home, depending on how much power it demands, and how much storage capacity you have. The benefits of owning a home battery are pretty amazing. Keep reading to learn about how a home battery can transform the way you think about, and use energy in your home.
Everyone wants energy security.
Every single American home relies on electricity to work creatively, communicate effectively, nourish our bodies, and regulate the temperature of our homes. We need power to keep up our lifestyle, and we need to know that it won&#;t shut off, especially when we need it the most. Most people take for granted that utility companies can meet the electricity demand of the public, but this is becoming less and less true. The power grid is an aging, fragile system that breaks down frequently, without notice, in the wake of strong winds, flooding, or a simple mishap with a squirrel (yeah, you heard the right. Squirrels actually disrupt the power grid on a pretty regular basis.) Grid-connected power customers can no longer count on the electricity utility companies to provide power whenever they need it.
With a home battery, you can take the power back into your own hands.
Home batteries give households a secure power source that they can use anytime they need it. Many households complete their home solar system with a home battery, so they can use the energy they store from their solar panels at night, after the sun goes down. Some consumers choose to keep their home batteries connected to the grid, so they can store back-up power in the event of a power outage. Either way, home batteries give their owners peace of mind, knowing that they will have electricity available to them, whenever they need it, whether the grid is up or not. That&#;s a great feeling.
Wish you could pay the bare minimum for electricity?
With a home battery, you can always take advantage of the very lowest electricity rates. Many states are beginning to implement peak demand power rates, or price hikes during the hours of the day when more people are sucking energy from the grid. Instead of paying a premium price for electricity when they need it the most, home battery owners can store energy from the grid when it&#;s at its very cheapest (usually in the middle of the night), and discharge their batteries during peak demand hours, so they&#;re essentially disconnected from the grid when rates are high. People refer to this as &#;time of use shifting,&#; a method many home battery owners use to slash their electricity bills down to the absolute lowest cost possible.
Want to say goodbye to your power bill entirely?
Storing grid energy in a home battery when it&#;s cheap can definitely save you money, but storing the clean, free energy from the sun can save you even more. Homes equipped with both a home battery and solar panels can soak up the sun all day, and store up the energy they&#;re not using in a home battery to be used after the sun goes down. Most households with solar panels feed their generated power back into the grid on a daily basis, since they&#;re not able to use the energy during the daytime hours when many people are out of the house. Wouldn&#;t you rather put your generated energy to work for you? With a home battery, you can keep solar energy stored up in you battery energy bank to use whenever you want. The best part about it? The sun offers its energy for free.
Solar + Battery Storage is an Option&#; Anywhere.
So, say you don&#;t live in sunny southern California. We get it. Not everyone can be so lucky. But that doesn&#;t mean you can&#;t set up a home battery, with or without solar panels. You may be more familiar with an older, less-awesome form of batteries: lead acid batteries. If you know anything about lead acid technology, you probably know that it struggles in really high or really low temperatures. Does this make you want to shy away from using a battery to store power where you live? After all, most people use a decent amount of the energy they demand from the power grid to either cool their homes during high temps, or heat their homes when it&#;s cold. Well, fear not. Lithium ion batteries don&#;t struggle with extreme temperatures the same way lead acid batteries do. Even when a home battery gets cold, it can still store and discharge almost as much energy as it would on a sunny day in LA. On the flip side of things, batteries can also withstand some serious heat. Though super high temps may cause you battery to drop some percentage points performance-wise, your battery isn&#;t going anywhere, and neither is your power. You can rely on battery capacity to be there for you, no matter the weather. Oh, we forgot to mention that batteries are virtually maintenance-free, and can charge and discharge thousands of times without losing function. It&#;s pretty awesome.
Cleaning Up the Power Industry
Clean, green energy has been making major headlines&#; not just lately, but for a long time now. Renewable energy is taking over more and more of the power industry, and it&#;s leaving behind an impressively small carbon footprint. Many people predicted that renewable energy would never fully take over because of the problem of intermittence: both wind and solar energy generation depend on a resource that isn&#;t constantly there; the wind dies down periodically, and the sun checks out at least once every day. Energy storage, like home batteries, completely solves the problem of intermittent renewable energy. By storing solar and wind energy, it can be made available consistently and reliably. Now, the only major barrier between us and a complete renewable energy takeover is&#; us.
There&#;s never been a better time to install a home battery.
If you&#;re still on the fence about the greatness of home batteries, you might be ready to take the leap after you hear about the funding available for households who install on-site energy storage. Californians can take advantage of SGIP, the Self-Generation Incentive Program that virtually pays homeowners to upgrade their home energy systems, and many others have local and federal funding available for battery installation as well. At Swell, we take it upon ourselves to know what&#;s out there, so we can get you as much money as possible to put towards a home battery. Hit us up if you have any questions.
So&#; what is a home battery? It&#;s an energy-storing, money-saving, security-giving powerhouse that you can set up in your own home, putting your power back into your hands. Need we say more?
With energy bills soaring and people getting tired of relying on fossil fuels, home energy storage is experiencing a growth in popularity in the UK.
These storage systems, most likely in the form of lithium-ion batteries, are also becoming an important component in enabling our transition to cleaner, greener energy.
Understanding the basics, benefits and scenarios of use when it comes to storing energy at home is a key step for homeowners considering this technology. This guide will help you get started on energy storage.
Home energy storage involves using a system to store energy for later use. You can store different types of energy, for example heat, but the most common type of home energy storage system uses a battery to store electricity. This article will concentrate on this type.
The idea with a home battery energy storage system is that you&#;ll be able to charge it up using either your own electricity generated from solar panels or from cheap energy acquired from the grid. Once stored, you&#;ll use this lower cost stored energy to power appliances in your home.
The use of home battery storage is growing in the UK and is becoming more commonplace with solar PV panel installation &#; as it should do in our eyes. You can read more on battery storage market trends here.
Setting it up isn&#;t too complicated for a professional. Most installers can fit and commission a domestic battery within a day.
The main components of a battery energy storage system is the battery itself, an inverter and a control centre. These shouldn&#;t take up too much space in your home, but you can get an idea of how big battery storage systems are here.
Simply put, the battery will store electrical energy when there&#;s a surplus and discharge that energy when it&#;s needed around the home.
It&#;s most common for a storage battery system to exist with a solar panel array. During the day, and particularly when the sun is shining, solar panels will generate electricity.
Some of that energy can be used immediately around your home, for example to power your fridge freezer or your lights. However, when there&#;s no or little energy demand from your house, such as when it&#;s empty in the middle of the day, the electricity being generated from your PV panels can go one of two ways:
Sometimes it can go both ways, such as when the battery is already fully charged. In terms of a hierarchy of using solar generated energy, it&#;s most efficient to use it in this way:
This is because it&#;s a lot cheaper to use your own renewable energy than it is to buy it from the grid. If you have solar panels without a storage battery, it&#;s likely you&#;ll be sending energy to the grid at a much lower price than you&#;ll have to buy it back at.
We go into more detail on storing energy from solar panels here.
Yes, you can store energy without solar panels. It&#;s not as effective as using a storage battery with solar PVs, but it can still be done.
Essentially, a battery can store energy from any source. Be it energy generated from solar and wind or coal and gas. Of course, we should be aiming for clean energy generation from renewable sources, but the electrical energy generated in the end is the same.
In homes without solar panels, battery storage systems can be charged by drawing power directly from the grid. This is particularly advantageous when combined with effective variable tariffs which make the price of electricity much cheaper during off-peak hours, such as in the early hours of the morning. This cheap power that&#;s been stored in your battery, can then be used during busy peak hours when the cost price of electricity is much higher.

Even without solar integration, energy storage systems can still help lower energy bills whilst providing back-up energy in the event of power cuts.
Battery storage without solar panels does have some drawbacks though. There&#;s a high initial investment, long pay back times, plus your house is still dependent on the grid and exposed to potential price fluctuations.
The most popular type of storage battery at the minute is lithium-ion. These batteries have leapfrogged their predecessor lead-acid battery cousins and haven&#;t looked back. Lithium-ion technology has taken the market by storm and is set to continue its growth into the future &#; the lithium-ion battery supply chain is expected to make huge growth of 30% every year from to .
Li-ion batteries offer better energy density, a longer lifespan, lower maintenance requirements, a higher depth of discharge and the prices are coming down quickly.
The growth of lithium-ion tech has made batteries more accessible to everyday households and businesses looking to make good, energy efficient progress that also makes sense from a cost-effectiveness perspective.
There are plenty of good brands out there with high quality batteries and long-lasting warranties of up to 15 years. Many modern batteries now reach 100% depth of discharge, like the ones available from GivEnergy, Tesla and Huawei. It&#;s also possible to &#;stack&#; modular batteries so you can improve and increase your storage capacity over time. Huawei do a good job of this.
Home battery energy storage systems offer several advantages to homeowners.
Financial
One of the most significant benefits is the potential to reduce electricity bills. Even without solar panels, batteries can be used to store energy from the grid during off-peak hours when rates are lower and used during peak hours when rates are higher. This is provided that you have a suitable variable tariff.
When combined with solar panels, battery storage can lead to even greater savings. Some estimates suggest that solar panels plus battery storage can reduce your annual electricity bill by up to 70%. In fact, our calculations show that a battery storage system can save you around £800 a year.
This is because battery storage with solar PV allows you to maximise the use of your own generated energy. Although you can export excess solar energy to the grid, it makes more financial sense to save this energy for your own use. At the same time, you&#;re also increasing your self-reliance and the overall efficiency of your renewable system. Read more on the benefits of solar battery storage here.
Environmental
In addition to the financial benefits, home battery storage contributes to a cleaner environment by reducing dependence on fossil fuels. If you&#;re storing your own renewable energy, you know it&#;s come from a clean, sustainable source &#; it doesn&#;t come much better than straight from the sun!
As the world continues its clean energy transition, investing in a home battery storage system can help future-proof your home and prepare you for upcoming developments in the energy sector. Additionally, the presence of green technology like battery storage is increasingly attractive to homebuyers, potentially adding value to your property and increasing its saleability.
In theory battery storage could supply enough energy to power a house, but it depends on a few critical factors, such as:
Whilst most people invest in battery storage to reduce their reliance on the grid and save money on energy bills, it&#;s essential to have realistic expectations about the system&#;s capabilities.
A solar battery can provide as much electricity per day as it can store and safely discharge. This is determined by its capacity (measured in kilowatt-hours or kWh), power output and depth of discharge (DoD).
In the UK, the average household uses between 6-10kWh of electricity per day. A well-sized 10kWh residential solar battery can theoretically provide enough electricity for a standard day in a three-bedroom home, powering lights, appliances and even a dishwasher or washing machine. However, energy sapping appliances like electric heating systems or electric vehicle chargers can quickly drain the battery, leaving it unable to power the rest of the house.
Additionally, seasonal weather variations greatly impact the efficiency of solar panels and battery storage. In the summer, a home with solar panels and battery storage may be able to go several days without using grid electricity. But in the winter, solar generation can drop to around a quarter of its summer output, making it less likely for the battery to fully power the home.
The cost of buying and installing a residential battery storage system will vary from manufacturer to installer. However, to give you a general idea, homeowners can expect to pay between £4,500 and £10,000 for a well-sized home battery storage system. The minimum cost for a small battery is around £2,500.
A helpful rule of thumb is to budget approximately £900 per kWh of storage capacity. For instance, a 5kWh system would cost around £4,500, whilst a 10kWh system might be around £9,000.
It&#;s important to note that installing battery storage separately from solar panels or retrofitting an existing solar setup with batteries tends to be more expensive. To maximise cost-effectiveness, it&#;s generally recommended to install batteries at the same time as solar panels.
The table below provides a estimate of the expected costs for a lithium-ion battery based on its capacity:
Battery size (kWh)Battery price3-5£2,500 &#; £5,-7£3,500 &#; £7,-9£5,000 &#; £10,-12+£8,000 &#; £13,000+Although lead-acid batteries are cheaper than lithium-ion, we don&#;t consider them to be a viable long-term solution. They have a short lifespan (< 5 years) and a lower performance compared to lithium-ion batteries.
There&#;s a marginal amount of financial support available from the government for installing battery storage in the average home. As of February , battery storage will be exempt from VAT, effectively providing a 20% discount on the cost of the system. This exemption applies even without investing in solar panels or other green technology. Aside from that, there aren&#;t any grants available like there are for installing heat pumps under the Boiler Upgrade Scheme.
The idea of home energy storage sounds great. But before investing you need to consider factors such as upfront costs, available space and long-term savings.
If your energy consumption is already low or you have limited space for a storage system, a battery may not be the most practical solution.
Additionally, the upfront costs of battery storage systems can be a barrier for some households, with prices ranging from around £4,500 to £10,000. Although long-term savings can be significant, those on a tight budget or facing long payback periods may find it challenging to justify the initial investment.
Practical considerations aside, there are certain scenarios where energy storage is definitely worth considering.
For example, if you have solar panels and your home is usually quieter during the day, a battery would be hugely beneficial. It&#;s during the day when you&#;ll be generating most of your energy, and without a battery, almost all of this will be sent to the grid.
Installing a battery at the same time as solar panels is often the most cost-effective and energy-efficient approach, but this may not always be feasible. If an immediate installation isn&#;t possible, retrofitting solar battery storage at a later date is still an option.
