Problem
The Savings page hourly breakdown shows a single "export" figure that combines PV surplus export and battery→grid discharge. Users cannot tell which is which, leading to confusion about what the optimizer is actually planning.
Reported by Frank (Belgium/Belpex, #126): at 09:00 with battery charging 24%→65%, the 2.33 kWh "export" is PV surplus — but the display makes it look like battery→grid discharge, which would be economically wrong at Belgian prices (sell €0.11 vs buy €0.34).
Proposed fix
Split the export column (or add a tooltip/sub-row) to show:
- PV export — solar surplus sent to grid
- Battery export — battery deliberately discharged to grid
This makes the optimizer's intent unambiguous and helps users validate that BESS is making sensible decisions for their pricing setup.
Context
Tracked in #126 (ENTSO-e/Belpex beta). Kept as a separate issue to avoid scope creep on the ENTSO-e PR.
