Commercial Solar Design Drawing Package

I’m putting together the full engineering package for a new commercial-scale solar installation and need a detail-oriented designer to prepare every drawing and document required for construction and approvals.

Deliverables I expect from you:

• PV array layout
• Single-line diagram
• Earthing & lightning arrestor (LA) layout
• Coordinate file in Excel
• Perimeter fencing layout
• Inverter Control Room (ICR) layout
• Inverter/DG transformer (IDT) foundation layout
• HT panel foundation layout
• LT panel foundation layout
• Complete bill of quantities (BOQ)
• String layout

All drawings must be clean, layered AutoCAD files (DWG) with matching PDF plots. Please follow relevant IEC standards and any local electrical codes; I’ll provide the site survey, equipment datasheets and my utility’s interconnection guidelines as soon as we start.

Because this is a commercial project, I’m open to whichever mounting approach—roof, ground or carport—you determine is most efficient for the site once you review my topographic survey. Optimise string sizing, conductor runs and protection schemes so the final set can go straight to the EPC and the utility without revision.

Submit the full package, along with a brief design note explaining your key assumptions, for acceptance.
