I will design solar systems, create autocad slds, and perform dc ac cable sizing
About this Gig
Looking for precise solar system design, an accurate AutoCAD Single Line Diagram (SLD), and detailed DC/AC cable sizing calculations for your PV project?
I offer professional electrical engineering drafting and design services tailored to meet international electrical standards (NEC / IEC) for residential, commercial, and utility-scale solar projects.
What I Offer:
- Single Line Diagrams (SLD) & Three-Line Diagrams: Detailed AutoCAD drafting showing inverters, combiners, disconnects, meters, and grid connections.
- DC & AC Cable Sizing: Ampacity calculations, voltage drop optimization (<2%), conduit sizing, and conductor selection.
- Overcurrent Protection (OCPD): Breaker and fuse sizing for strings, arrays, and inverter outputs.
- System Layouts & Schematics: String layout configuration, tilt angle optimization, and equipment specification matching.
- Complete AutoCAD Drafting (.DWG & PDF): Clean, industry-standard engineering sheets with title blocks and bill of materials (BOM).
Why Choose Me?
- Technical Precision: Engineering-grade calculations to prevent voltage drop and power loss.
- Clean Drafting: Professional AutoCAD layout standard ready for contractors, consultants, and approval

FAQ
What information do you need to calculate cable sizes?
I need the string configuration, total cable run lengths (DC distance from panels to inverter, AC distance from inverter to panel), equipment specs, and target voltage drop limits.
Do you deliver source files in AutoCAD format?
Yes, all packages include the editable .DWG source file along with high-resolution ready-to-print PDFs.
Do you handle both IEC and NEC standards?
Yes, I perform cable sizing and electrical design according to both NEC (North American) and IEC (International) electrical standards based on your location.
Can you handle large commercial or utility-scale systems?
Absolutely. For systems larger than 100 kW, send me a message for a custom offer based on your project scope.
