Solar battery FAQ's

Will batteries work with all solar panels?

Batteries can be 'AC coupled' or 'DC coupled'. DC coupled is efficient but specific to solar. AC coupled can charge from various sources, like cheap grid power, and offers more installation flexibility. Whichever you pick, with a trusted installer like London Charging, it’ll pair nicely with your solar setup.

Can I pair a smart battery with my current solar panels?

Absolutely. If you've previously installed solar PV panels, we can provide and install a battery for you to both store and sell your generated solar energy. To get started, schedule a free site survey One of our specialists will guide you on costs and installation timelines.

How do solar panels paired with batteries differ from those without?

Solar with a battery
- Stores and utilises more of your solar energy.
- Less reliance on the Grid
- Access to greener energy, even at night
- Eligibility for the Smart Energy Guarantee (SEG) – they pay you for excess energy!

Solar without a Battery
- You only utilise 20-40% of the solar energy produced*
- Energy bills incurred during nighttime or rainy winter days

How do solar batteries work?

Your battery stores electricity for later. Sometimes you generate more solar power than you use, especially if everyone’s out. On not-so-sunny days, instead of relying on the grid, you've got stored energy to use

If I want to install a battery will you survey my property for free?

Of course! Our site surveys for battery installations are 100% complimentary.

How long do batteries last?

Duration-wise, a full-charged battery like the Tesla Powerwall 2 might power your home for over a day. Lifespan-wise, after thousands of charges, batteries might hold a bit less power, but they come with around a 10-year warranty. And in our experience, they usually outlive that by a good bit.

What warranties and guarantees do we offer?

A 10-year warranty on the product. A 25-year guarantee for performance. A decade-long warranty from battery manufacturers.A warranty for workmanship backed by insurance. A life cycle guarantee ranging from 6,000 to 10,000 cycles.

What size battery do I need?

Home batteries come in different sizes. UK households typically use 8-10 kWh daily. Batteries range from smaller 2.5-5 kWh units to larger 13-15 kWh ones. It's a mix of matching your nightly usage with what your solar system produces.

Notes

*Reduce power cuts
According to Ofgem, battery storage systems are essential for maintaining power supply during outages in a renewable energy-based grid, significantly reducing the risk of power cuts.

*Attain up to 23% ROI, dwarfing the 3.1% from usual savings
This claim is supported by data from the Energy Saving Trust, which shows that solar panel investments can yield a significant ROI, particularly when combined with battery storage and government incentives. The ROI of 20-25% over the lifespan of the solar panels significantly outperforms typical UK savings account returns, which are generally around 2-5%

*On average, save more than £900 annually
The Energy Saving Trust and other government sources highlight that solar panel installations can lead to substantial annual savings, depending on factors such as location, system size, and electricity prices. These savings can exceed £900 annually in optimal conditions​.

*You only utilize 20-40% of the solar energy produced
Most households without battery storage use only 20-40% of the solar energy they generate, with the remainder typically exported to the grid.
