Comprehensive Solar System Design Redesign

I’m coordinating several solar projects that range from blank-slate builds to upgrades of installations already in the field. The portfolio covers everything from small residential rooftops through mid-size commercial facilities, up to large industrial plants and one ground-mounted array.

For each site I need a complete system design and layout together with the full electrical integration package. That includes optimised module stringing, inverter and combiner box selection, conduit and cable routing, protection and monitoring equipment, plus all calculations for wire sizing, voltage drop and fault current. Drawings should be delivered in CAD (DWG) and accompanied by single-line diagrams, bill of materials and manufacturer-ready specifications. Using tools such as AutoCAD, PVsyst, Helioscope or similar is fine as long as the final set meets local code (NEC or IEC as applicable) and is ready for permitting or EPC handoff.

I’ll provide site data, load profiles and any as-built documents I already have; you return a clean, engineered design package that can be stamped as soon as a PE reviews it.
