First numbered estimate for the solar roof: 20 LONGi 370 panels at
about 19.5 kg each plus fixed rails, the self-supporting sliding
frame (aluminium mandatory, steel would double it) and cabling land
around 650-700 kg. Recorded in the weight tracker and the roof
concept doc with the structural and centre-of-gravity implications.
Deep regulatory research (15+ official sources, RTI 03.8.3 sheet read
in full): the TCP-to-VASP procedure is nailed down (13-item dossier,
seat reduction handled inside it, 86.90 EUR), but two blocking
uncertainties surfaced. First-registration date may forbid the
conversion or require a ministerial derogation, and no firm text
covers the sliding solar deck. Both flagged as blocking questions in
parcours-vasp.md and solaire-toit.md: DREAL first, fabrication later.
Block-diagram the validated architecture as movable shapes and texts:
PV decks feeding MPPT (DC) and Fronius (AC-coupled), MultiPlus and
Pylontech bank on a highlighted 48V DC bus, P17 shore input, AC and
DC boards, Cerbo GX. Gives the electrical folios a reviewable
starting point instead of a blank page.
QElectroTech 0.100.1 is now installed locally, so the qet/ folder
gets its actual project file: five pre-named folios matching the
documented plan (synoptic, 48V DC, 230V AC, rooftop PV including the
sliding deck, monitoring/interlocks) with house title-block fields.
README updated from install instructions to open instructions.
Split the schematic tooling by audience: QElectroTech (IEC 60617,
versionable XML) for the 48V/230V/PV installation folios that
electricians and inspectors read, KiCad kept for in-house boards
(monitoring, solar-deck interlock). Seed qet/ with the folio plan
and conventions; record the decision.
