Our Tesla Powerwall 2 has been installed for 2 years 2018 2020. I look at the costs to install, the Powerwall's performance and statistic, how we operate it and how much we have saved. Will it pay for itself? I cover any issues and did we make the right decision. Does a Powerwall work in the UK? Will a home battery get a return on investment?

Update:
@15:04 mm:ss should have been times 24 months, not 48! This means the saving is £36.78 per month. So £57 £36.78 = £20.22 per month for the cost of the Powerwall! Thanks to @bonbon who pointed this out.

The savings quoted were only ever correct at that point in time the video was uploaded. If we look at current energy prices in the UK (April 2022) they have doubled/tripled, then the savings will be dramatically reduced. Energy prices are only ever going to be going one way. A new video can be found here with newer savings and costs:    • Our total costs for our home energy g...  

I have not included the cost of the solar installation for 2 reasons. First, the 2011 4kW solar install had paid for itself with FiT payments by Dec 2018, the same month the battery was installed. Secondly, the video was about the Tesla Powerwall 2 battery and was it worth it. Whilst it's part of an overall system, it was this component I was concentrating on.
