I have a complete conceptual and preliminary layout for a residential photovoltaic installation that now needs to be converted into formal engineering documents. The job is two-fold: • A single-line diagram that is truly comprehensive—every conductor, protection device, junction, label, rating, and specification must be shown. The drawing has to cover interface protection and the full emergency-shutdown path, strictly following the current Saudi PV standard. Only solar panels and inverters are required at this stage; no storage or generator blocks are needed. • A matching mechanical design that translates the electrical intent into real-world mounting, spacing, and enclosure plans. All dimensions, clearances, and material notes have to be exact so procurement and installers can build directly from the sheets. I will supply the conceptual sketch and the preliminary bill of materials. You return professional CAD drawings (PDF + editable format) ready for authority submission. Use any mainstream electrical CAD platform—AutoCAD Electrical, EPLAN, or similar is fine—as long as layer names and symbols remain standard. Before hand-off, I will review schematics for compliance. Acceptance is achieved once the drawings pass that review and align with the cited Saudi PV standard clauses.
