🔋 Battery Storage Without Solar Panels
Smart Energy. No Roof Needed.
Not every home can install solar panels — but that doesn’t mean you have to miss out on energy savings or independence.
Whether you live in a terraced house, a property with shading from trees, or a listed home in a conservation area, a battery-only system gives you control over your energy bills and backup power without any panels on your roof.
⚡ How It Works
A smart battery automatically charges when electricity is cheapest and powers your home when rates rise — often cutting bills by 35–45%.
You can:
✅ Store low-cost energy from the grid overnight
✅ Power your home during peak times
✅ Protect against power cuts with full-home backup
✅ Add solar panels later if your situation changes
🧠 Perfect for All Types of Homes
Terraced or town houses with limited roof space
Properties shaded by trees, chimneys, or other buildings
Homes with complex or multi-pitch roofs
Listed buildings and conservation areas
You don’t need planning permission, scaffolding, or visible panels — just a compact, wall-mounted battery and smart management.
❓ Battery-Only Storage – Frequently Asked Questions
1. Can I really have a home battery without solar panels?
Yes. A battery can work entirely on its own. It charges from the grid during cheap, off-peak hours and powers your home when rates are higher — saving money without generating solar electricity.
2. How much can I save with a battery-only system?
Typical households on smart tariffs such as Octopus Go, Intelligent Octopus, or EDF Go Electric can save 35–45% on electricity costs each year by storing cheap power overnight.
3. What happens during a power cut?
With systems such as the Tesla Powerwall 3 you get full home back up. With Fox ESS, or SolaX, you can add full-home back or EPS which is only a couple of small circuits (some lights, fridge}.
With a full home back up your lights and appliances stay on even when the grid goes down this is a switch that can be added to other battery combinations. Ask us.
With an EPS Emergency Power Supply its not a full home back up.
4. Is it worth installing a battery now if I might add solar later?
Absolutely. A battery-only setup is fully compatible with future solar panels. When you’re ready, your system can simply connect — no re-installation or wasted investment.
5. What size battery do I need?
It depends on your household’s energy use and tariff.
Most homes install between 5 kWh and 13 kWh of storage. However to make the most and of you want a full home back up then 10kW is the minimum. Tesla Power Wall 3 has 13kW as standard and you can connect up to 4 batteries.
RRD Energy will calculate the right capacity.
