This is my energy analysis for 2024, to assess the impact of my smart home solar installation project. The project was started in October 2022 and my energy analysis page explains how my returns/savings are calculated. Previous years include: 2023.

If you are considering moving to Octopus, you can use this referral link and Octopus will give us both £50.

October 2024

At the start of October, I moved us to the Intelligent Octopus Go tariff. By my calculations, this should save us another £520 per year.

The average rate has increased to 4.1p per mile as we have charged the CUPRA Born on the day rate on several occasions.

As expected, our gas savings this month were much lower. This is simply because we are paying almost half the kWh rate on the Octopus Tracker (December 2023 v1) tariff that we were paying on the variable rate tariff.

February 2024

Note: From 1st February 2024, I moved us on to the Octopus Energy Tracker tariff (December 2023 v1). We could have done this without doing our smart home solar installation project, so we are using this tariff for our baseline costs going forward. This will reduce our measured savings and increase the time it takes us to pay back on our investment but, I want my Return On Investment (ROI) numbers to reflect the 'real world' savings possible.

My daughter has been using the CUPRA Born to commute to London a lot. This has meant we sometime have to charge it during the 'day rate' on the Octopus Flux tariff tariff.
