Amortisation of Photovoltaic System

Energy
1

Hi folks,

I’m really new to Home Assistant and don’t quite understand the underlying system, so I’m kind of lost trying to create a metric:

My Photovoltaic System had a total cost of like 30k€. From the solaredge integration, I can read the total amount of energy produced, used by my home, and the amount sold to the electricity company for 7c/kwh.

With these values and a time span of, let’s say, ten years, I should be able to calculate, on a monthly basis, how far I am regarding amortisation of the system.

Problem is: I have no clue where to begin in home assistant as none of the helpers would be suitable for such task and I have nowhere to save variables etc.

Any immediate idea how to approach this topic?

Thanks in advance for any guidance and help!

PS: I’m a bit short of time due to the baby needing attention, so I might not reply immediately :heart:

The way I do it is by exporting the daily production, usage and the amount of energy fed into the grid to a csv. Later I have a small jupyter notebook to analyse the data.

The export part:

notify:
  - platform: file
    name: Export Stromzaehler
    filename: /config/stromzaehler.csv
    timestamp: false
