500kW Solar Plant Technical Designing, BOM and Drawing preparation

I need a full design package for a 500 kW ground-mounted solar plant. Using the site’s topographical features and climate data, please produce engineering-ready documentation that lets my EPC team move straight into procurement and construction. Scope of work • Drawings: deliver clear 2D CAD drawings, true-to-scale plant layout maps and eye-level 3D renderings that show row spacing, access roads, inverter stations and cable trenches. • Bill of Materials: create a detailed spreadsheet that lists every required item—solar panels, inverters, mounting structures, all cabling and ancillary accessories—complete with part numbers, quantities, and technical specs. • Geographical integration: all layouts must respect the real terrain profile, sun path and shading, optimising string sizing and inverter allocation. Preferred tools are AutoCAD (or equivalent) for 2D plans, SketchUp or similar for 3D visuals, and PVsyst or Helioscope for generation and shading validation; feel free to suggest alternatives if you can meet the same level of accuracy. Acceptance criteria 1. CAD files in DWG plus PDFs for quick reference. 2. 3D model file and high-resolution renders. 3. BOM in Excel with filtrable columns and summary totals. 4. A brief design note explaining tilt choice, estimated annual yield and any assumptions on soil bearing or geotech factors. Once I approve the preliminary layout, proceed to the final set and BOM. I’m ready to begin immediately and will be responsive for quick feedback cycles.
