Place solar panel components
Drop a panel template, auto-fill the roof, see the shade-loss per hour, connect to an inverter. The output respects local regulation defaults.
Quick answer
- Library → Solar → drop the panel template on the roof.
- Right-click → Auto-fill. Diaz lays out panels avoiding obstacles.
- Run
Tools → Shade analysis (hourly). Connect to inverter on E-layer.
Step-by-step
- Open the Library panel (shortcut
B) and pick the panel template that matches the brand on your offer: Trina, JA Solar, REC, LG, or generic. Wattage range 300–500 Wp is pre-filled. - Drop one panel anywhere on the roof — Diaz snaps to the roof slope. Right-click the placed panel → Auto-fill roof. Diaz lays out panels covering the roof while keeping clearances from edges and obstacles (chimney, dakkapel, ventilation).
- Run shade analysis:
Tools → Shade analysis (hourly). Diaz uses the address from your project header to look up sun-path data and renders per-hour shade-loss per panel. Panels with >15% annual shade loss are marked yellow — consider removing or accepting. - Connect to inverter: drop an inverter on the E-layer (meterkast/contador), right-click → Connect to panel array. Diaz checks DC string voltage, AC output, and warns if the AC capacity exceeds your grid-connection limit. NL: household grid-connection is ≤ 3×80A (kleinverbruik); above is grootverbruik with a different tariff regime.
- Export the permit pack:
File → Export → PDF → Permit pack. Output includes panel layout, string diagram, shade chart, yield-estimate per month, and the BOM. NL: compliant with NEN-1010 chapter 712 (PV-specific). ES: outputs include the documents required by RD 244/2019 — Memoria Técnica or Proyecto depending on installed power per Comunidad Autónoma.
Watch out
- NL salderingsregeling stops 1 January 2027 — energy suppliers must still pay at least 50% of the bare delivery tariff until 2030, but it stops being a 1-to-1 settlement. Sizing logic in Diaz reflects this. Source: Rijksoverheid.
- String over-voltage at low temperature: Diaz warns if string Voc at -10 °C exceeds the inverter input limit. If the warning fires, reduce string length by one panel and re-check.
- Local regulation always wins: Diaz templates reflect the latest known rules but are not a substitute for a final design review. For larger or grid-connected systems, confirm with the local installer-certification body before submission.
