- scripts/import_dad_p1.py converts his 15-min cumulative meter dump
(~/Downloads/P1e-2025-1-1-2026-1-1.csv) into our hourly format.
Net of PV exports — power_w can be negative on surplus hours.
Aligned to our 2023-09 → 2024-09 window by (month, day, hour) so
prices and irradiance stay seasonally matched.
- data/raw/p1_hourly.csv is now dad's data; ours preserved as
p1_hourly_michiel.csv for diff/comparison.
- LP gE upper bound was 'pv[t]'; now max(0, pv − demand). This was
wrong before but invisible because demand was always positive; with
dad's net data demand goes negative and the LP went infeasible.
- New 'Export rate' field in Advanced. Override saldering toggle with
a literal €/kWh — set to −0.106 for terugleveringskosten.
