Hi,
I'm currently on the Octopus Go tariff, and noticed they are trialing larger time spreads but for increased p/kwh.
That got me thinking about home power storage- Tesla Powerwall or something else.
Has anyone in the UK completed the calculations (Total Cost of Ownership) and worked out if its worth it purely from a financial point of view. Currently I don't have any solar panels. We live in a village with no mains gas, so house heating is currently bulk LPG. ~20kwh usage per day (not including car charging)
The ideal would be low upfront cost, and either get a cheap loan or lease the battery system. Hopefully the savings would more then 100% offset the finance.
Excel sheet calculation would be nice ?
BTW- Its a pity the BMW i3 we have can't feed it's remaining charge back into the house when the Mrs returns home each evening (normally at least 50% charge remaining), then fully charge it again overnight. One for the future.
