What I see
/api/sfml_stats/amortization builds its series from the start of the previous billing year (2025-01 here) up to the current month — 20 observed months — regardless of commissioning_date. I set commissioning_date to 2021-07-04 via the settings dialog and the window did not move.
settings.commissioning_date: 2021-07-04
series: 2025-01 … 2026-08 (observed_months 20)
accumulated_benefit_eur: 3865.97 progress 16.6 % break-even 2035-05
stats_daily_energy holds complete data from 2021-07-07 (I back-filled it from my storage system's 5-minute export; yearly PV 12.2 / 11.9 / 11.5 / 12.6 MWh for 2022–2025). With those years included, the picture is quite different: roughly 10.4 k€ of a 23.3 k€ net investment recovered (about 45 %), break-even around 2032 instead of 2035. For a plant that went live five years ago, the current view makes it look three years worse than it is.
Suggestion
- Start the amortization history at
max(commissioning_date, first date with data in stats_daily_energy) instead of the previous billing year. The monthly benefit can use the same fixed/GPM pricing as today.
- Alternatively (or additionally) a field in the settings dialog like "benefit before tracking started (€)", so users without old data can enter what their plant has already earned, and the progress ring and break-even start from the right point.
- If neither is wanted, a short note in the card that only the last two billing years are counted would at least avoid misreading.
Nothing urgent, and I can test a build against the five years of data I have. Thanks for the tool — the consumer atlas and the billing table are exactly what I was missing.
