Battery Storage Solutions (Domestic-Focused)

Maximise your home’s energy efficiency with a domestic solar battery storage system, expertly designed by Solar Trading UK and installed by One Energy South West. Enjoy reduced energy bills, enhanced energy independence, and a sustainable home powered by clean solar energy.

Your Path to Energy Savings

A solar battery system lets you store surplus energy generated by your solar panels during the day for later use. This smart energy management means fewer reliance on grid electricity and significantly lower monthly bills.

According to the Energy Saving Trust, each kWh used from battery storage saves about 14p compared to grid electricity.
Recent market data shows UK households with solar storage can now save up to 64% on energy bills—not just from solar power, but by storing and using it effectively  .

Benefits That Stand Out

1. Reduced Energy Bills
By storing hours of solar generation, you avoid drawing expensive daytime electricity.

2. Time-of-Use Tariff Optimisation
Charge from the grid during off-peak hours (e.g. Economy 7 tariffs) and use stored power when rates are highest—potential savings of over 11p/kWh  .

3. Energy Independence & Backup
Battery-equipped homes can lessen reliance on the grid—or stay powered during outages with backup function models  .

4. Better Solar ROI
Homeowners typically recoup investment in ~10–15 years via savings and export earnings under SEG  .

5. Environmental Benefits
Boost your home’s renewable energy use and reduce carbon emissions—an important step toward sustainability goals.

 
How We Install

Our streamlined battery installation process ensures efficiency and peace of mind:

  1. Assessment & Design – We recommend the ideal battery size and type for your energy use.

  2. Fit & Wiring – Our team safely connects the battery to your inverter or fuse board, typically within 1–2 days  .

  3. Grid Notification – We handle Distribution Network Operator (DNO) updates or permissions if needed.

  4. Commissioning & Hand-Over – Your system is tested and demonstrated, with aftercare support and warranty ensured.

Although internal installations (such as in a garage, utility room, or loft) are still possible, we recommend external installations for added safety. For outdoor setups, we also suggest using battery and inverter covers to protect your equipment and enhance the overall appearance.

Domestic FAQs & Choosing the Right System

What size battery do I need?
Average UK homes benefit from 5–10 kWh systems; three-bedroom homes typically start around 8 kWh  .

Which type is best—lithium-ion or lead-acid?
Lithium-ion offers greater capacity and longevity, while lead-acid is more cost-effective up-front  .

How long do solar batteries last?
Expect 10–15 years with 10-year warranties—but this varies by model and usage  .

Does it work during a blackout?
Only if your battery includes “islanding” or EPS backup configuration (requires separate relays)  .

Are there grants or VAT benefits?
Yes—VAT on battery systems is currently 0%, reducing upfront costs, and SEG lets you earn for exported electricity  .
