Store Your Power. Use It When You Need It.
Solar panels generate electricity during the day. You use most of yours in the evening. Without a battery, you’re giving away free power and buying it back at five times the price.
Works with new solar installations or existing systems.
You're Generating Free Electricity. Then Giving It Away.
Here’s what happens without a battery:
Your solar panels generate power all day while you’re at work. You’re not there to use it. So it goes back to the grid. The energy company pays you a few pence per unit.
Then you come home. Cook dinner. Run the washing machine. Watch TV. Charge your phone. Now you need electricity — but the sun’s gone down.
So you buy it back from the grid. At 30-40p per unit.
You generated it for free. Sold it for pennies. Bought it back for pounds.
A battery fixes this. Store your free daytime electricity. Use it whenever you want. Stop subsidising the energy companies.
Simple Technology. Massive Impact.
During the day, your solar panels generate more electricity than you’re using. Instead of exporting it to the grid for pennies, that excess power charges your battery.
In the evening, when the sun goes down and your usage goes up, your battery kicks in. You run on your own stored electricity instead of buying from the grid.
Some systems can even charge from the grid overnight when rates are cheapest, then power your home during expensive peak hours. That’s savings on top of savings.
It’s your electricity. You should get to use it.
Why Add Battery Storage.
Use Your Solar Power 24/7
Generate during the day, use at night. Finally get the full value from your panels.
Slash Your Evening Bills
Evening electricity is the most expensive. Battery power is free.
Protection From Price Rises
The more you use your own stored power, the less exposed you are to grid price hikes
Backup During Power Cuts
Some systems keep your lights on when the grid goes down. Peace of mind included.
Maximise Export Payments
Store when export rates are low, export when rates are high. Smart systems do this automatically.
Future-Proof Your Home
As energy prices rise and time-of-use tariffs become standard, battery storage becomes more valuable every year.
Battery Options To Suit Every Home.

Already Got Solar? Add A Battery.
You don’t need to start from scratch. Batteries can be retrofitted to almost any existing solar system.
If you installed solar a few years ago and skipped the battery — now’s the time. Battery prices have dropped significantly, and electricity prices have gone the other way. The maths makes more sense than ever.
We’ll check your existing setup, make sure everything’s compatible, and integrate the battery seamlessly.
Same installer. Same warranty support. Simple.
Not Just Storage. Smart Storage.
Modern battery systems aren’t dumb boxes. They’re smart energy managers.
Time-Of-Use Optimisation
Uses weather data to predict tomorrow's generation and adjusts storage strategy accordingly.
App Monitoring
See exactly what's happening in real time. Generation, storage, usage, savings - all on your phone.
Grid Services
Some systems let you earn money by helping balance the national grid. Your battery works for you even when you're not using it.
Backup Mode
Keep critical circuits running during power cuts. Fridge, lights, internet - whatever matters most.
We’ll set it up to maximise your savings automatically. You don’t need to think about it.
The Payback Is Faster
Than You Think.
A few years ago, batteries were expensive and payback took forever. Not anymore.
Battery costs have dropped. Electricity prices have soared. The gap between what you’d sell power for and what you’d buy it back for has never been wider.
For most homes with solar, a battery now pays for itself in 5-7 years. After that, it’s pure savings for another 10-15 years of battery life.
And if you’re on a time-of-use tariff like Octopus Go or Intelligent Octopus, payback can be even faster.
We’ll run the numbers for your specific situation. No guesswork.

for quick, reliable guidance.
How much can I actually save with a battery?
Depends on your solar system size, your usage patterns, and when you use electricity. Most customers increase their self-consumption from around 30-40% to 70-80%. We’ll give you realistic projections based on your actual situation.
How long do batteries last?
Most modern batteries are warrantied for 10-12 years and will keep working beyond that at reduced capacity. Think of it like a phone battery – it doesn’t die suddenly, it just holds a bit less charge over time.
Can I add a battery to my existing solar system?
Almost always yes. We’ll check your inverter compatibility and electrical setup. Some systems need a small upgrade, but most can just add a battery directly.
Will the battery power my whole house during a blackout?
Depends on the setup. Standard installations don’t provide backup. If you want blackout protection, we can configure specific circuits to stay live — but it costs a bit more. We’ll discuss options.
Is it worth getting a battery if I don't have solar?
It can be, if you’re on a time-of-use tariff. Charge overnight when electricity is cheap (often 7-10p/kWh), use during the day when it’s expensive (30-40p). But honestly, batteries work best paired with solar.
How big should my battery be?
Depends on your evening usage. We’ll look at your consumption patterns and recommend a size that actually makes sense – not the biggest one we can sell you.
Where does the battery go?
Most are wall-mounted in garages, utility rooms, or sometimes outside. They’re about the size of a small suitcase. We’ll find a spot that works.
What about fire risk?
Modern lithium batteries from reputable manufacturers have excellent safety records. We only install certified products with proper thermal management and protection systems.
What Our Battery Customers Say
Battery Customer:
Added a battery to our two-year-old solar system. Our evening usage from the grid has dropped to almost nothing. Should’ve done it when we got the panels.

Battery Customer:
The app is brilliant. I can see exactly when we’re using stored power versus grid power. We’re using about 80% of what we generate now instead of 35%.

Battery Customer:
We’re on Octopus Go. The battery charges overnight at 7p and powers us through the expensive hours. The savings are
ridiculous.
