For commercial and industrial rooftops. Engineers draw the roof once, and the plugin lays out modules, strings, trays, cables and earthing, then produces the good-for-construction (GFC) drawings and quantities.
Client drawings stay private, so every picture here is our own drawing with sample data. Each tool reads what the one before it drew, so a change on the roof flows through to the quantities.
Layout
Module placement
Fills a roof area with PV modules from a shared library, for the roof type you pick, around obstructions and walkways.
Metal roofs, RCC roofs and carports
A uniform grid, or fitted around obstructions and irregular edges
Modules kept clear of roof edges, ridges and exclusion zones
Shadow analysis first, to see which areas to keep clear
1 more
Capacity and coverage for every PV area
1Module tables on an RCC roof, laid out around obstructions
2Modules on metal roofs, in rows either side of the walkways
Electrical
Cables and trays
DC cables routed along guidelines to each inverter, AC cables on to the distribution boards and the point of connection, with trays and conduits drawn, sized and labelled.
DC cables from the strings to each inverter, along your guidelines
AC cables from inverter to the sub-main distribution board (SMDB), and SMDB to the point of connection
DC cable sizes chosen by voltage drop
String and inverter schedules, with lengths and voltage drop

Conduit while the cables fit, cable tray beyond that
Trays as hatched bands with labelled centrelines
Bends, T and cross junctions as fitting blocks

2AC cables from the distribution boards to the point of connection
3A cable schedule for every string and inverter, with voltage drop
4Trays and conduits drawn into the inverters, sized and labelled
5Tray lengths by size, fittings and conduit in one BOQ
Earthing
Earthing layout
Earths every roof in the drawing in one go, by the rules of its roof type: strips and earth pits on RCC roofs, clips and jumpers on metal roofs.
Every roof in the drawing earthed in one run
Metal roofs: legs in the table gaps or walkways, joined into a ring
RCC roofs: a strip between table rows and a trunk on the inverters' side
Clips and jumpers at the module joints
4 more
Earth pits with their down conductors
Inverter and SMDB earthing
An ESE lightning arrester
Earth pit coordinates and an earthing BOQ, in Excel or the drawing
1Strips and earth pits on an RCC roof
2Clips and jumpers on a metal roof
3Strip, cable, clips, pits and arrester, in one BOQ
Operations
Module cleaning system
Lays out the water network of each PV area: a water point and pump, a header, branches and taps, so every module is within reach of the hose.
A water point and pump for each PV area
A 1" header and 3/4" branches on a UPVC network
Taps placed so every module is within the hose's reach

Outputs
Summaries and BOQs
Each tool keeps its own summary, and the project summary brings them together: capacity, module counts and coverage for every PV area, ready for the BOM workbook in Excel.

What the team gets
A construction-ready set.
GFC sheets, with the earthing and cleaning layouts
Yes. This one was built for one solar developer, so yours would be built around your standards, roof types, title blocks and BOM format. We start from your own drawings.
Which roof types does it cover?
Metal roofs, RCC roofs and carports. Each PV area follows the rules of its roof type for placement, earthing and module cleaning.
Which CAD versions does it run on?
This suite runs on AutoCAD 2021 to 2027. A new tool would target the versions your team uses.
Does it cover stringing and the single-line diagram?
Yes. You declare the strings for each inverter and MPPT, and the single-line diagram is built from the drawn strings in one click, with one panel for each distribution board.
What's in the construction set?
A titled A0 sheet set, picked from a catalogue of 23 drawings: power and earthing single-line drawings, setting-out plan, DC string layout, cable routing, earthing and arrester layouts, module cleaning, and walkway and lifeline arrangements.
How are quantities handled?
Each tool keeps its own summary, and the project summary brings capacity, module counts and coverage together. Tray, earthing, cleaning and lifeline BOQs export to the drawing or Excel, and the BOM workbook collects the materials by category.
What happens when a roof changes?
Run the tool again. Module cleaning works one PV area at a time, so the others stay as they are, and earthing covers the whole drawing in one go.
How is it installed and updated?
Through an installer with email sign-in, and updates arrive automatically.
Will you keep our drawings private?
Yes. We keep client drawings and project details private, and we're happy to sign an NDA before you share drawings.
