Battery Storage UK — Solar Energy Storage for Homes
Store excess solar energy and use it when you need it most with a home battery storage system. Battery storage helps Manchester homeowners maximise their solar investment, reduce reliance on the grid and lower electricity bills throughout the year.
Why Install Battery Storage With Your Solar Panels in Manchester?
A battery storage system stores excess solar energy generated during the day for use at night or during peak demand. You maximise the value of your solar panels by using more of your own renewable energy instead of exporting it — reducing reliance on expensive grid electricity and improving your energy independence.
Use More of Your Solar Energy
Without a battery, a typical home uses 30–50% of its generated solar electricity (the rest is exported for a small SEG payment). With a battery, self-use typically increases to 70–90% — your own free electricity instead of buying from the grid.
Lower Energy Bills
Use stored solar energy during peak-rate hours (4–7pm, when electricity is most expensive) and avoid buying expensive grid electricity at night — typically saving around £200–£400 per year on top of your solar savings, depending on usage and tariff.
Backup Power (With Hybrid Systems)
Some battery systems provide backup power during grid outages — keeping lights, fridge, internet and phone chargers running. Valuable for homes with vulnerable residents or home offices.
Reduce Your Carbon Footprint
Using stored solar energy reduces reliance on grid electricity, which may come from fossil fuels — maximising your renewable energy usage.
How Does Battery Storage Work?
Solar panels generate DC electricity, which an inverter converts to AC for your home. Any excess that isn’t used immediately charges the battery — then, when your panels aren’t producing (evening, night, cloudy periods), the stored energy powers your home. A typical day:
Generate & Charge
Solar panels generate electricity; your home uses what it needs. Excess electricity charges the battery — once full, any further excess is exported to the grid (SEG).
Automatic Discharge
Solar generation stops and the battery automatically discharges to power your home — you use stored solar electricity instead of buying from the grid.
Battery Then Grid
The battery continues until empty (typically 2–5 hours depending on battery size and usage) — then the grid takes over automatically.
Smart Recharge (Optional)
On a time-of-use tariff, the battery can recharge from cheap off-peak grid electricity before solar generation starts.
What Battery Storage Options Do We Offer?
AC-Coupled Battery
Retrofit to existing solar systems — works with any existing inverter, so it’s the most common choice for existing solar owners. Easier installation with no changes to your existing solar system. Typical efficiency: 90–92%.
DC-Coupled Battery
Installed alongside a hybrid inverter — more efficient (typically 94–96%) but requires a compatible inverter. Best for new solar installations where the right inverter can be specified from the start.
Standalone Battery (No Solar)
Charged from the grid at cheap rates (e.g. Economy 7 or an overnight EV tariff) and discharged during peak hours — no solar required. Best for homes that cannot install solar (shaded roof, flat roof, listed building).
What Battery Size Do You Need for Your Manchester Home?
Battery size depends on your household energy usage, solar output and daily consumption patterns. Most Manchester homes benefit from a 5kWh–10kWh system for balanced efficiency and cost — a proper assessment ensures the battery is correctly sized to maximise self-consumption.
Small Household
- Who: 1–2 people, low usage
- Solar size: 3–4kWp
- Recommended battery: 5–7kWh
- Indicative cost: £3,000–£5,000
- Backup duration: 2–3 hours (essential loads only)
Medium Household
- Who: 3–4 people, typical usage
- Solar size: 4–6kWp
- Recommended battery: 8–12kWh
- Indicative cost: £5,000–£8,000
- Backup duration: 4–6 hours
Large Household
- Who: 4+ people, high usage, electric car
- Solar size: 6–10kWp
- Recommended battery: 13–20kWh
- Indicative cost: £8,000–£15,000
- Backup duration: 6–10 hours
How Is Battery Storage Installed in UK Homes?
Free Consultation
- We assess your solar system (or design a new one), energy usage patterns and storage needs
Design
- We specify battery size, type (AC or DC coupled) and installation location (garage, utility room, outside wall)
Installation
- AC-coupled (retrofit): battery unit installed near the existing inverter, energy management control unit fitted, connected to the consumer unit
- DC-coupled (new solar): hybrid inverter and battery installed; solar panels, battery and grid connected
- Typically 1 day for AC-coupled, 2 days for DC-coupled
Commissioning
- System commissioned; charge/discharge settings configured (time-of-use tariffs, backup reserve)
- Monitoring app access provided
How Much Does Battery Storage Cost in UK?
Costs depend on system size, brand, storage capacity and whether the system is integrated with solar PV. Larger systems provide greater energy independence and better long-term savings.
| System size | Example systems | Indicative cost range | Suitable home size | Best use case |
|---|---|---|---|---|
| Small (5kWh) | GivEnergy 5.2kWh, SolarEdge 5kWh | £3,000–£5,000 | 2–3 bed homes | Basic solar storage for daily use |
| Medium (10kWh) | GivEnergy 9.5kWh, Tesla Powerwall 13.5kWh | £5,000–£8,000 | 3–4 bed homes | Balanced energy storage & night usage |
| Large (15kWh+) | GivEnergy 13.5kWh + expansion, Tesla Powerwall 2 | £8,000–£15,000 | 4+ bed homes / EV users | Maximum solar independence & EV charging |

Frequently Asked Questions
Can I add a battery to my existing solar panels in Manchester?
Yes — AC-coupled batteries work with any existing solar system, regardless of inverter type.
How long does a battery last?
Typically 10–15 years, depending on usage pattern and battery chemistry (lithium iron phosphate or NMC). Typical manufacturer warranty: 10 years or 6,000–10,000 cycles.
Is battery storage worth it without solar panels?
Batteries are most cost-effective with solar panels. Without solar, charging from the grid (even at off-peak rates) may have a longer payback — typically 8–12 years.
Can a battery power my home during a power cut?
Only with additional equipment (EPS or hybrid systems with islanding capability) — standard batteries shut down during grid outages for safety. We advise on backup options.
Can I get a grant for battery storage in Manchester?
Battery storage is not covered by ECO4 or the Boiler Upgrade Scheme. However, VAT is 0% on home battery storage until 31 March 2027 — whether installed with solar, retrofitted or standalone — and some local authorities may offer interest-free energy improvement loans.
