Powervault: The UK’s Answer To Tesla’s Powerwall

By : Chris Tipping |July 29, 2017 |Energy, Energy Blog |0 Comment

Considering the multitude of press coverage around Tesla’s Powerwall it won’t be news to most of us that solar power storage is here. However, due to the attention Tesla have been grabbing it may be news to you that they aren’t the only ones that offer a solar power storage solution. The UK Company, Powervault, offers a great product from a comparatively humble origin.

Solar Power Storage Solution

Joe Warren, Managing Director of Powervault, is keen to point out his products ability to make light of a common snipe thrown at solar power, ‘Solar power provides power during sunlight… but people are out most of the day’. The Powervault solar power storage battery renders this point almost irrelevant. This issue is the cornerstone of the company, thanks to the Powervault customers can have their energy when they actually need it.

How it works

The Powervault battery stores energy generated during the day so it can be used in the evenings. The battery monitors a household’s usage and offsets the amount needed by the grid by the amount it has stored. This results in a reduction in electricity costs because there is a reduction in the demand on the grid. It works much the same way as other solar power storage systems but has a few interesting features designed specifically for the average British household. The sizing of the unit is an indication of how much thought has gone into putting this technology into British homes; the Powervault is about the same size as a washing machine.

Reality of capacity

The storage unit can hold around 2 to 4 kWh. As we’ve discussed before on our energy blog it is a little difficult to get your head around how much a kWh of energy can give you in real terms. Let’s look at it this way, 1 kWh can power a television for around 7 hours or wash 1 full load, this means the Powervault offers up to 28 hours of TV time or up to 4 full loads.


The Powervault costs from £2,000 up to £2,800. The company aiming to drive their price point down quickly, especially due to the imminent arrival of the Tesla Powerwall in the UK by the end of the year. Powervault are a much smaller operation and won’t be able to compete on price with Tesla but there are some interesting comparisons to be made.

Comparisons to Tesla

When compared to Tesla’s Powerwall which boasts 7 kWh or 10 kWh capacity the UK alternative seems to fall a little short. However, estimating that the price tag of the 10kwh Tesla Powerwall will be somewhere around £3,700 (including the installation of a converter), £2,000 doesn’t seem to be extortion, nor a steal for that matter. Considering that the price of the Powerwall is just estimated from the current American retail price, the UK’s Powervault may end up being considerably cheaper.

When it comes to commercial energy, Tesla have the upperhand with their fully extendable Powerpack. The Powervault is a purpose built household storage system.

Despite Tesla offering a well-designed streamlined solution for solar energy storage, the Powervault offers a product specifically tailored to the needs of UK homeowners.
