As Independence Day approaches, we’re flipping the switch, both literally and figuratively.
At Sunlit Solar, we believe that true independence goes beyond flags and fireworks. It’s about energy independence and gaining the power to take control of your own energy future. With the latest in solar and storage technology, you’re no longer at the mercy of rising energy prices, fossil fuel dependency or grid instability.
This year, we’re proud to introduce a new generation of solar batteries, designed for maximum sustainability and performance:
🌊 The Sodium Battery System by Eleven Energy.
Let’s explore what makes this innovation a game-changer for homes and businesses across the UK, and why now is the perfect time to go energy independent.
What Is Energy Independence?
Energy independence means producing and storing your own electricity, typically through solar panels and battery storage, so you can reduce reliance on the National Grid, cut your energy bills, and protect yourself from blackouts, price spikes, and supply disruptions.
With smart battery storage like Eleven Energy’s sodium-based system, you can store the energy your panels generate during the day and use it at night, during peak hours, or even to power your EV. It’s freedom from fossil fuels and full control over your energy.
The Sodium Battery Revolution
Eleven Energy’s battery system is a sustainable alternative to lithium-ion technology, and it’s here to transform how we store and use solar energy.
Why Sodium, Not Lithium?
Lithium has powered the energy revolution so far, but it comes with major environmental and ethical concerns:
- Water-intensive mining consumes over 1.9 million litres per tonne of lithium extracted.
- Operations disturb ecosystems, threaten biodiversity and affect local communities who rely on the land and water.
- Demand for lithium is expected to rise over 40x by 2040, leading to even greater environmental strain.
In contrast, sodium is over 1,400 times more abundant than lithium and is extracted ethically from seawater and common minerals. It avoids the harmful environmental impacts of lithium mining and offers a cleaner, more ethical choice for energy storage.
Eleven Energy: Designed for the Future
Eleven Energy’s sodium battery system, soon to be available through Sunlit Solar, is more than just a battery, it’s a smart, sustainable energy ecosystem.
Eco-Friendly and Sustainable
- Made from non-toxic, widely available materials
- Cathodes use industrial byproducts (like iron and manganese oxide)
- Anodes made from abundant resources such as cardboard or straw
- No cobalt, no rare earth metals, no environmental guilt
Extreme Temperature Performance
Unlike lithium batteries (which operate best between 0°C and 40°C), Eleven’s sodium battery performs reliably from -20°C to 55°C, perfect for the UK’s variable climate across seasons.
Smart Energy Management
With a built-in Intelligent Energy Management System, this battery doesn’t just store energy, it optimises it:
- Seamlessly integrates with solar panels, EV chargers and home appliances
- Tracks your tariff schedules and solar forecasts
- Maximises savings by prioritising when and how your stored energy is used
Built for Simplicity and Trust
The system includes a 6 kW Single Phase Hybrid Inverter and 4.5 kWh sodium battery pack, all backed by industry-standard certifications and safety documentation, including:
- G99 and G100 Certificates
- EMC and Low Voltage Conformity
- Material Safety Data Sheets
- Installation Manuals and Warranty Documents
- Cybersecurity Declaration
It’s a plug-and-play solution that’s safe, robust and ready for the future.
Powered by Purpose
The name “Eleven” itself is inspired by sodium’s atomic number, a symbol of their mission to create clean, ethical energy storage that moves the world forward.
Make This (Energy) Independence Day Count
This Independence Day, take the step toward true freedom:
✅ Say goodbye to fossil fuels
✅ Say hello to smarter energy storage
✅ Gain independence from rising energy bills and unreliable supply
Whether you’re ready to retrofit your current solar system or starting from scratch, Sunlit Solar can help you design an energy solution that’s sustainable, future-ready, and tailored to your needs.
