Can I add a battery to my existing solar panels?

Yes. Battery retrofits are one of our most common installations. We assess compatibility with your existing inverter and wire in the battery with minimal disruption. Most retrofit installations take 4-6 hours. If your inverter is not compatible, we can quote for a hybrid inverter replacement as part of the same project.

Is solar battery storage worth it in 2026?

For most Hampshire homeowners, yes. Without a battery, you typically self-consume 30-40% of your solar generation. A battery increases this to 70-85%, saving an additional £350-600/year at current electricity prices. On a smart tariff (Octopus Agile, Intelligent Flux), savings can exceed £1,100/year combined with solar. Typical payback: 7-10 years on a system rated for 15+ years.

What size battery do I need?

For a 3-bed home with 4-5kW solar: 10kWh battery. 4-bed home with 5-6kW solar: 13.5-15kWh. Large home or EV charging: 20kWh+. A battery should be sized to store roughly 80% of your daily solar generation in summer. We calculate the optimal size at your free site survey based on your electricity usage, roof size, and EV needs.

Which is better: GoodWe, Fox ESS, SigEnergy or GoodWe?

All four brands we install use LiFePO4 (lithium iron phosphate) chemistry — the safest type. GoodWe: best warranty extension (free 10-year PLUS+), excellent value. Fox ESS: UK market leader, proven Octopus Flux compatibility. SigEnergy: the only brand with integrated 25kW DC EV charging and V2H — ideal for EV households. We recommend the right brand for your specific situation.

Can my battery charge from the grid overnight?

Yes. On tariffs like Octopus Agile, Go, or Intelligent, electricity costs as little as 7p/kWh between midnight and 6am. Your battery charges overnight at this rate and discharges during daytime/evening peak rates of 25-30p/kWh. The difference (approximately 18-23p/kWh) on a daily 10kWh battery cycle creates savings of £600-800/year from tariff arbitrage alone, on top of solar self-consumption savings.

Where can a battery be installed in my home?

The most common locations: garage (preferred — easy ventilation and service access), utility room on an external wall, or outdoor weatherproof cabinet (for bungalows without garages). Under PAS 63100:2024, batteries cannot be installed in loft spaces, bedrooms, under stairs, or main living areas. We assess your property and recommend the best location at the survey.

Do batteries qualify for the 0% VAT rate?

Yes. Standalone battery storage systems qualify for 0% VAT (since February 2024). This applies whether you are adding a battery to existing solar or installing a new combined system. The 0% rate is confirmed until March 2027 — meaning you save 20% on the system cost versus pre-2024 prices.

Why Newbury?

Battery Storage for Newbury Homes

Newbury's position in West Berkshire brings excellent sunshine and a housing stock of 1960s-1990s family homes and modern developments that are well-suited to battery storage. The town's growing commuter population and rising energy costs drive increasing adoption of solar and battery systems.

Newbury commuters travelling to Reading, London, or along the M4 corridor leave homes empty during peak solar generation. Battery storage captures 70-85% of generation that would otherwise be exported at poor rates. The financial case is compelling: combined solar + battery + smart tariff savings regularly exceed £1,000 per year.

Newbury is 45 miles from our base. We serve the RG14 and RG20 postcodes for homeowners seeking specialist solar and battery installations. The town's modern housing stock with garages provides straightforward installation conditions.

Customer Reviews

Battery Storage Customers in Newbury

Added a Fox ESS 10kWh battery to our existing solar. Went from exporting 60% of our generation to using 85% of it ourselves. Electricity bill under £20/month now.

James T., Fareham · Fox ESS 10.24kWh

The SigEnergy system charges overnight on Octopus Agile at 7p and discharges in the evening at 28p. The payback calculation just made so much sense.
