Have you ever looked at your electricity bill and wondered why you’re still buying energy from the grid when your solar panels generated plenty of electricity during the day?
That’s where battery storage comes in. Without a battery, any electricity your solar panels don’t use immediately is usually exported back to the grid. While you may receive a payment through the Smart Export Guarantee (SEG), you’re often selling that electricity for much less than it costs to buy it back later in the evening. A battery storage system changes that.
Instead of exporting your unused electricity, it stores it safely so you can use it later, whether that’s making dinner, watching television, charging your devices or putting the kettle on after work. Think of it like cooking a big family meal and freezing the leftovers. Rather than throwing perfectly good food away, you save it until you need it. A home battery does the same thing with the energy your solar panels generate.
The result?
Capture excess solar electricity during the day and use it later, helping reduce reliance on the grid and increase energy independence.
Charge your battery on cheaper tariffs, monitor performance from your phone and reduce both electricity costs and your carbon footprint.
Battery storage can help you use more of the electricity you generate, reduce your reliance on the grid and manage your household energy more efficiently.
Without a battery, many households use only around 30–40% of the electricity generated by their solar panels. Battery storage can increase this to around 70–80% or more.
Household electricity use is often highest between 4pm and 9pm, when solar generation is lower. A battery stores excess daytime energy for use later in the evening.
Modern battery systems can include smartphone monitoring, backup power options and compatibility with existing solar installations, giving you greater control over your energy use.
Some batteries can charge overnight using lower-cost off-peak electricity, allowing you to store cheaper energy and use it during more expensive daytime periods.

At GLANtech Solar, we don’t believe in one size fits all systems. Every home is different, which is why we take the time to design a solar solution that’s tailored to your property, your energy usage and your future plans. From your first enquiry to installation and aftercare, we’re here to make switching to renewable energy simple, straightforward and stress free.

The easiest way to think about a battery storage system is like a thermos flask for electricity.
If you make a cup of tea and pour it into a flask, you don't have to drink it straight away, you save it until you need it. A home battery does exactly the same thing with electricity.
During the day, your solar panels often generate more electricity than your home is using. Instead of sending that spare energy back to the grid, the battery stores it for later. Then, when the sun has gone down or your family is using more electricity in the evening, your home can use the stored energy first before buying electricity from your supplier.
At GLANtech Solar, we design battery storage systems to help you make the most of the electricity you generate, giving you greater energy independence and helping to reduce your electricity bills.
For many households, absolutely.
Imagine filling your car with fuel, only to watch half of it pour onto the road because you couldn't store it. That would seem like a waste.
Without a battery, that's often what happens with excess solar energy. If you're out at work during the day, your solar panels may be producing plenty of electricity while nobody is home to use it. A battery allows you to keep that energy until you need it.
Battery storage can also work with smart electricity tariffs, allowing you to charge your battery overnight when electricity is cheaper and use that lower-cost electricity during the day.
We'll always explain whether battery storage makes financial sense for your home rather than recommending it simply because it's the latest technology.
Yes, in most cases you can.
It's a bit like adding a garage after you've bought your car. You didn't need both on day one, but adding one later makes life much easier.
Many of our customers had solar panels installed years ago before battery storage became popular or affordable. We can assess your existing system and recommend a compatible battery that works alongside it.
Adding battery storage often allows homeowners to use much more of the electricity they're already generating instead of exporting it back to the grid.
If your current equipment needs upgrading to work efficiently with a battery, we'll explain the options clearly and recommend the solution that's right for you.
This is probably the question we're asked more than any other, and it's easy to see why. We all know the British weather isn't famous for endless sunshine!
The good news is that solar panels don't need bright sunshine to work, they need daylight.
A simple way to think about it is a day at the beach. Even when it's cloudy, you can still come home with sunburn because the sun's rays are still getting through. Solar panels work in much the same way. They continue generating electricity on cloudy days, they just produce more when the sun is shining brightly.
A well-designed solar PV system can reduce your electricity bills throughout the year, and with energy prices changing so often, generating your own power gives you far more control over what you spend. Every home is different, so we design each system around your roof, your family's electricity usage and your future plans to make sure you get the best possible return on your investment.
Every battery installation is different because every home use energy differently.
It's like buying a water tank. A small household doesn't need the same storage capacity as a large family.
The cost depends on the battery size, the manufacturer, your existing solar system and whether it's being installed as part of a new solar installation or added to an existing one.
At GLANtech Solar, we don't believe in selling the biggest battery available. Instead, we'll recommend the battery size that best matches your electricity usage so you're investing in storage you'll benefit from.
Modern lithium battery systems are built for the long term.
Think about your mobile phone. You charge it every day and expect it to last for years. Home batteries work in much the same way; except they're designed for thousands of charging and discharging cycles.
Most quality home battery systems come with warranties of around 10 years, and many continue performing well beyond that depending on how they're used.
We only install trusted battery brands with proven reliability because we want your investment to continue working efficiently for many years after installation.
This is one of the most common questions we receive. The answer is sometimes, but not automatically.
Think of it like buying a generator. Simply owning one doesn't mean your house will switch over by itself during a power cut. It needs the correct equipment to do that safely.
Some battery storage systems include backup power capability, while others are designed purely to store solar energy and reduce electricity bills.
If having power during a power outage is important to you, let us know during your survey. We can recommend systems that include backup functionality and explain exactly what appliances they'll be able to power.
Yes, you certainly can. Many people assume batteries only work with solar panels, but that's not the case.
Think of it like charging your phone overnight when electricity is cheaper instead of during the day when demand is higher.
A home battery can charge from the electricity grid during cheaper off-peak periods and then power your home during more expensive times of the day.
While combining battery storage with solar usually provides the greatest savings, battery only systems can still be an excellent option for households using smart electricity tariffs.
Choosing the right battery is a bit like buying a fridge freezer.
If you live on your own, buying the biggest one available probably isn't the best use of your money. Equally, a small fridge isn't ideal for a family of five.
The right battery depends on how much electricity your household uses, when you use it and whether you have solar panels or an electric vehicle.
At GLANtech Solar, we'll look at your electricity usage rather than simply recommending the largest battery available. Our aim is to find the right balance between cost, storage capacity and long-term savings.
Yes, that's exactly what it's designed to do. Imagine doing your weekly food shopping when everything is half price instead of paying full price every day. That's essentially what battery storage allows you to do with electricity.
If you have solar panels, your battery stores free electricity you've generated yourself instead of buying it later from the grid.
If you're on a smart tariff, your battery can also charge overnight when electricity prices are lower and use that stored electricity during the day when prices are higher.
The result is less reliance on the grid and more control over your household energy costs.
Battery storage isn't simply about fitting a box to the wall.
It's about understanding how your household uses electricity and designing a system that genuinely works for you.
Think of it like having a tailored suit made rather than buying one straight off the shelf. Both will do the job, but one has been designed specifically to fit.
At GLANtech Solar, we take the time to understand your home, your current electricity usage and your future plans before recommending any battery system.
