Expert Battery Storage Installation for Burnley Homes

Battery storage transforms your solar installation from a daytime-only system into a round-the-clock energy solution. Store the excess power your panels generate during the day and use it in the evening when electricity rates are highest. With a properly sized battery, you can increase your self-consumption from around 40% to over 80% — meaning more of your own free energy and less money going to the grid.

How Does Solar Battery Storage Work?

During daylight hours, your solar panels generate electricity. Any power not immediately used by your home is stored in the battery rather than being exported to the grid at low Smart Export Guarantee rates. When the sun goes down and your panels stop generating, the battery supplies your home — avoiding expensive grid electricity at peak evening rates.

Modern smart batteries like the GivEnergy and Tesla Powerwall go further than simple charge-discharge cycles. They can be configured to take advantage of time-of-use tariffs like Octopus Agile, charging from the grid during cheap overnight periods (as low as 7p/kWh) and discharging during expensive peaks (30p+ /kWh).

What Batteries Do We Install?

GivEnergy

GivEnergy is a UK-headquartered manufacturer with an excellent reputation for reliability and customer support. Their hybrid inverter and battery systems are designed specifically for the UK market:

• Capacity options: 2.6kWh, 5.2kWh, 8.2kWh, and 9.5kWh modules (stackable)
• Warranty: 10 years
• Hybrid inverter: Manages solar, battery, and grid in one unit
• App monitoring: Real-time energy flow, historical data, remote control
• Price range: From £2,500 for a basic unit

Tesla Powerwall

Tesla’s Powerwall is the most recognised home battery globally, with a sleek design and proven track record:

• Capacity: 13.5kWh per unit (expandable up to 3 units)
• Warranty: 10 years
• Backup gateway: Automatic switchover during power cuts
• App monitoring: Tesla app with Storm Watch and energy forecasting
• Price range: From £4,500 installed

How Much More Can You Save with a Battery?

Without battery storage, a typical 4kW solar system in Burnley with 40% self-consumption saves approximately £750 per year. Adding a battery increases self-consumption to 80%+, boosting annual savings to approximately £1,200 — an increase of around 60%.

The additional cost of battery storage (£2,500–£5,000) typically pays back within 5–7 years, after which the increased savings are pure profit for the remaining life of the battery.

Retrofit Installation: Adding a Battery to Existing Solar

Already have solar panels installed by another company? We specialise in retrofit battery storage — adding a battery to your existing system without modifying your current panels or inverter.

The process is straightforward: we assess your current system specification, recommend a compatible battery, and install it — typically in half a day. Your existing MCS certificate and Feed-in Tariff or SEG registration remain unaffected.

Time-of-Use Tariff Optimisation

Smart batteries aren’t just for solar storage. Paired with a time-of-use electricity tariff like Octopus Agile, Octopus Go, or Intelligent Octopus, your battery can charge from the grid during cheap overnight periods and discharge during expensive daytime peaks.

This means savings even on days when solar generation is low — the battery arbitrages the price difference between cheap and expensive electricity automatically, based on the schedule we configure during installation.
