Earn £1 per kWh From Your Solar Battery With Axle Energy
Most solar export tariffs in the UK pay around 15p per kWh when you send electricity back to the grid.
But what if you could earn £1 per kWh instead?
That’s exactly what Axle Energy is offering homeowners with compatible battery systems. Through their Virtual Power Plant platform, Axle pays homeowners £1 per kWh when their battery exports energy during short periods when the grid needs extra support.
At Sunbright Energy, we’ve partnered with Axle Energy to help homeowners get even more value from their solar battery systems. If you already have a compatible battery, you could start earning extra income simply by allowing your system to support the grid a few times per month.

Who are Axle Energy?
Axle Energy is not an energy supplier. Instead, it’s a UK-based software platform that connects home energy devices to electricity markets.
Their goal is to help balance the electricity grid using renewable technology instead of fossil fuels.
They do this by connecting devices such as:
Home battery systems
Solar panels
EV chargers
Heat pumps
When thousands of these devices are connected together, they effectively form what’s known as a Virtual Power Plant (VPP).
Rather than relying on traditional power stations, the grid can draw small amounts of energy from many homes at once. This helps stabilise the electricity network while making better use of renewable energy.
Why the Grid Needs Extra Support
The electricity grid must always stay balanced. That means electricity supply must match demand at every moment.
Historically, the grid has managed this by turning fossil fuel power plants up or down to meet demand spikes. These are often called “peaker plants”, and they are typically powered by gas.
As more renewable energy is added to the grid, balancing supply and demand becomes more complex. Solar and wind generation can fluctuate, while electricity demand can spike suddenly.
Axle Energy’s platform helps solve this problem.
Instead of turning on fossil fuel plants, the grid can draw energy from distributed renewable technologies, including home batteries. By releasing small amounts of stored electricity during short demand spikes, homeowners can help stabilise the grid while earning money in the process.
How You Earn £1 per kWh
Axle Energy pays homeowners when their battery exports electricity during what are known as grid events.
A grid event is a short period where the electricity grid needs extra support to stay balanced.
During these events:
Axle automatically exports energy from participating batteries
The exported electricity helps support the grid
Homeowners earn £1 per kWh exported
Grid events typically happen around 3–6 times per month, and they usually last for a short period of time.
To put that into perspective, most UK export tariffs pay around 15p per kWh. Axle’s rate of £1 per kWh is roughly 6–7 times higher than many standard export payments.
Your earnings are automatically credited to your Axle account whenever your battery participates in an event.

Real Example: A Sunbright Customer Earned £6.30 in One Event
One Sunbright Energy customer recently participated in a grid event and exported 6.30 kWh from their battery.
For that single event, they earned £6.30.
While each event is relatively short, these payouts can add up over time.
Axle Energy is also currently trialling a £10 per month minimum payment guarantee, meaning if your total earnings don’t reach £10 in a given month, Axle will top it up.
If this continues long term, it means many homeowners could expect at least £120 per year in additional income from their battery.
Do You Lose Control of Your Battery?
This is one of the most common questions homeowners ask.
The short answer is no.
Your battery will continue to operate based on the schedule you set through your home energy app or battery management system.
Axle Energy only exports energy during brief grid events, which typically occur 3–6 times per month.
Outside of those events, you remain fully in control of your battery.
It’s also worth noting that exporting energy during these events is simply normal battery cycling — something batteries are designed to do regularly. The system always operates within the manufacturer’s recommended limits.
If there were ever a power cut, your battery would prioritise powering your home, and grid export would automatically stop.
Does It Affect Your Energy Tariff or Supplier?
No. Axle Energy works alongside your existing electricity supplier and tariff.
You do not need to switch energy providers to use the service.
It also works alongside:
Smart tariffs
Export tariffs
FIT payments
This means you can still export electricity normally whenever you choose and receive your usual export rate from your supplier.
Axle events simply create additional opportunities to earn money from your battery.
What You Need to Join Axle Energy
To participate in Axle Energy’s Virtual Power Plant, homeowners will need:
A smart meter
A compatible home battery system
Currently supported battery brands include:
Fox ESS

How to Get Started
Getting started with Axle Energy is straightforward.
1. Sign up using the Sunbright referral link
If you sign up through Sunbright Energy, you’ll receive a £25 signup bonus when your account is activated.
2. Connect your battery
During the signup process, Axle will ask you to:
Upload a recent electricity bill
Connect your battery system to their platform
This allows Axle to communicate with your battery during grid events.
3. Everything runs automatically
Once connected, the system runs in the background.
Axle monitors grid demand and automatically dispatches your battery during grid events. When this happens, your earnings are credited directly to your Axle account.
You’ll receive email notifications whenever events occur or when earnings are added to your account.
There are no exit fees, and you do not need an MCS certificate to participate.

A Simple Way to Earn More From Your Battery
Home battery systems already help homeowners reduce electricity bills by storing solar energy and reducing grid imports.
Axle Energy creates an additional opportunity by allowing batteries to earn money while supporting the electricity grid.
By participating in occasional grid events, homeowners can earn £1 per kWh exported, potentially generating £120 or more per year in additional income.
The system runs automatically, works with most energy suppliers, and doesn’t require any changes to your existing tariff.
If you already have a compatible battery, it’s one of the simplest ways to get even more value from your system.
