What is the Tesla Powerwall 2 solar battery and how does it work?

Tesla Powerwall Specs

The Tesla Powerwall 2 is a lithium-ion solar battery that can be recharged. This Tesla battery storage has one of the highest energy storage capacities on the market today, with a total capacity of 14 kWh and a usable capacity of 13.5 kWh

The Tesla Powerwall works by storing excess energy produced by your solar panels for later use. It then discharges this energy when your household requires electricity, namely when your solar panels don’t produce enough, like when it’s dark out. This solar battery is also a great option for storing energy in case of a power outage, as a fully charged Tesla Powerwall can supply enough energy for your home for up to 24 hours. 

Some of the key characteristics of the Tesla Powerwall include: 

Tesla Powerwall 2 Technical Specifications
Total capacity14kWh
Usable capacity13.5kWh
Efficiency 90%
Depth of discharge100%
Dimensions150 x 75 x 15cm
Weight115kg
Operating temperature-20°C to 50°C
Warranty10 years

What is the Tesla Powerwall availability in the UK?

While it is one of the most popular solar batteries in the UK today, having a Tesla Powerwall installed in your home is not exactly easy. This is because there is currently limited availability of Tesla Powerwall units in the country.

As a result, even if you purchase this appliance, you might have to wait for quite some time before you can enjoy any of its benefits. Some users across the UK have had to wait months or even years before they had the Tesla Powerwall installed in their homes.

So, if you want to avoid the long waiting time, you can also consider other solar battery options that are more readily available. To find out which great alternatives to the Powerwall can work for you, make sure to consult a solar battery expert for tailored advice.

Tesla Powerwall costs in the UK

The cost of the Tesla Powerwall 2 in the UK today is around £5,800. However, you will also need to account for installation costs and any supporting hardware you might require. Adding these components to the cost of the Tesla Powerwall unit, your total expenses can range anywhere from £7,100 - £9,300.

Below you can find an overview of all the costs associated with installing a Tesla Powerwall 2 in your home: 

Costs of Installing a Tesla Powerwall 2
Tesla Powerwall 2£5,800
Upfront deposit£400
Supporting hardware£800
Installation£800 - £3,000
Total costs£7,800 - £10,000

By considering the impressive characteristics of the Tesla Powerwall and weighing it against the total cost of having one installed in your home, you may conclude that purchasing this solar battery might be a worthwhile investment for your home. 

However, if you are purchasing your Tesla Powerwall at the same time as your solar panels, you will also need to consider how much solar panels cost. By installing your solar battery at the same time as your solar panels, you can save on installation costs. 

Tesla Powerwall monthly costs in 2024

Powerwall monthly costs

If you have the funds to invest in a Tesla Powerwall and can cover the upfront costs, then you will not have to worry about monthly payments. However, if spreading out your expenses is more feasible for you, then you may be able to spread out the costs of a solar array over 36-120 months. In this case, you will need to check whether such an approach can also be extended to a solar battery in your situation.

At the same time, you should be mindful of any potential interest rates that come with spreading out the cost of your new system. Additionally, your monthly costs can also be influenced by any maintenance or repairs your Tesla Powerwall may need. 

For context, a typical Powervault 3 cost can be £12,000 for a battery with a similar capacity.

Are there grants for the Tesla Powerwall 2 in the UK?

Tesla Powerwall grants

There are a few solar panel grants and schemes that you can also benefit from to lessen the financial burden of installing a Tesla Powerwall 2. Currently, these are: 

  • Smart Export Guarantee (SEG): With this incentive, homeowners can earn money back by selling excess energy generated by their solar panels back to the grid. A solar battery can help you store this energy. If you apply for the SEG, you can earn between 5.5 and 15p per kilowatt sold back to the grid. 
  • 0% VAT: You can benefit from the VAT reduction if you install your solar battery at the same time as your solar panel system. You should also make sure that the installation of both your solar panels and your battery storage is carried out by the same installer to fully benefit from 0% VAT. This way, you can save over £1,000 on solar panel and battery installation.
  • Home Energy Scotland Loan: This interest-free loan is accessible to people living in Scotland who want to install more efficient energy systems in their homes. By applying for this loan, you can receive up to £4,750 to install solar panels and solar batteries. 

Will you save money on your energy bills by installing a Tesla Powerwall battery?

Solar panels and a solar battery can help you save on your yearly electricity bills. However, it is good to keep in mind that your total savings with a solar battery in the UK are highly dependent on factors such as the storage capacity of your solar battery, the cost of electricity in the country, and how much electricity your household consumes.

When it comes to the Tesla Powerwall 2, you can save up to £900 per year on your energy expenses. This means that you will break even on your investment in the solar battery unit in about 6 years

To maximise your savings with a Tesla Powerwall, you will need to make sure that this battery storage option fits well with your solar system. The surest way to determine whether this solar battery is the best choice for your home is by consulting a solar expert.
