Roof plan & array layout
Roof faces, pitches, setbacks, panels and dimensions.
Solar design drawings
AccuracyQuickReliable
Engineered from a 3D model.
Drawn to the millimetre.
Roof layouts, string plans, single line diagrams, mounting and cable routes — a complete, permit-ready drawing set for your solar project.
01 · Model
Every roof, measured.
Faces, pitches, ridges, setbacks and skylights modelled in 3D from your plans, site photos and survey data.
02 · Layout
Every panel. Every string.
Module layouts, string lengths and MPPT allocation checked against the inverter and the module datasheets.
03 · Connect
Array to switchboard.
Cable trays sized to the strings they carry, inverter locations, comms, emergency stop and earthing.
04 · Issue
One model. A full drawing set.
A3 sheets with your title block, schedules and notes — ready for the installer, the engineer and the council.
What you get
A drawing set, not a sketch.
Every sheet comes from the same 3D model, so the roof plan, the string plan and the single line diagram always agree.
Array set-out
Dimensioned module positions on every roof face.
PV string plan
String colours, wiring order and MPPT allocation.
Installation areas
Edge and intermediate zones and minimum rails.
3D views
Isometric views of the building and the array.
Mounting & bill of materials
Rails, brackets, clamps, stock lengths and quantities.
Single line diagram
Strings, DC isolators, inverter, switchboard, metering and earthing.
Equipment & cable schedules
Equipment, cable routes and lengths, labels and datasheets.
Cable tray
Trays sized for the strings they carry, from roof to inverter.
Comms & control
Comms cabinet, LAN and emergency stop cabling.
Roof fixing details
Fixing details for the chosen roof profile.
Energy yield
Hourly simulated generation, month by month.

Why Sun Crafted
Designed in our own software, sheet by sheet.
We build each design in Sun Crafted — our own 3D solar design studio — so the drawings come out of a real model rather than being drafted by hand.
- Consistent sheetsOne model behind every plan, schedule and diagram.
- Electrical checksString voltages, MPPT limits, voltage drop and isolator ratings worked out from the datasheets.
- Installer-ready detailSet-out dimensions, rail runs, brackets, cable routes and labels.
- Standards notedDrawings reference AS/NZS 5033, AS/NZS 3000 and AS/NZS 4777 for the electrical designer.
- Clean energy, done rightDesigns that get more roofs generating clean power — sized, checked and ready to install.

FAQ
Questions
What do you need from me?
Just the site address and how to reach you. Architectural plans, roof photos, the panels and inverter you have in mind, or a target system size all help us quote accurately — attach them if you have them.
What does a drawing set include?
Typically the roof plan and array layout, set-out, string plan, 3D views, mounting layout with bill of materials, single line diagram and the equipment and cable schedules. Cable tray, comms and emergency stop, roof fixing details and energy yield sheets are added when the project needs them. Your quote lists what's included.
What formats do I get?
A3 PDF sheets with a full title block. CAD (DXF) export of the layout is available too.
How do I accept the quote?
The quote arrives by email with an Accept quote button. One click and we start on your drawings.
Do the drawings replace an electrical designer?
No. The drawings set out the design and reference the relevant standards; protection devices, cable sizes and final approval remain with the responsible electrical designer.
