Electrical V2
Manual or automatic stringing, MPPT allocation, import/export and link repair.
SolarLayer ZW · 2026.2.2.00
2026.2.2.00: electrical design becomes a true engineering layer.
This release consolidates Electrical V2 and normative traceability while preserving SolarLayer ZW 3D, terrain, mapping and layout capabilities.
Electrical V2
A complete electrical workflow, from string to single-line diagram.
The 2026.2.2.00 branch adds a true electrical engineering layer to SolarLayer ZW: stringing automation, MPPT allocation, routing, sizing, protection, checks and deliverables.
DC / AC cabling
Automatic or guided routing using ducts, cable paths, buildings, access ways or technical rooms.
Sizing
Cross-sections, allowable current, voltage drop, losses, temperature, grouping and installation method.
IEC · BROOF
Explainable calculations and normative traceability.
IEC 60364-5-52:2009 + AMD1:2024
Selection and erection of wiring systems: installation methods, current-carrying capacity, temperature, grouping and voltage drop.
IEC 62548-1:2023 + AMD1:2025
PV array design: DC wiring, protection devices, isolation, earthing and safety requirements for the PV generator.
EN 13501-5:2016 + CEN/TS 1187:2012
BROOF traceability for roofs. SolarLayer records and checks the documented class, including BROOF(t3) or BROOF(t4), without claiming to calculate the fire class.
