I will design utility sld and nec compliant solar interconnection
Renewable Energy Engineer
Professional Renewable Energy Engineer specializing in utility-scale solar and BESS design, providing expert PVSyst modeling and AutoCAD/PVCase engineering for developers and EPC firms worldwide.
About this Gig
Ensure a seamless utility approval process with precise, code-compliant electrical engineering. I specialize in designing utility-scale Single Line Diagrams (SLDs) and NEC-compliant solar interconnection schematics engineered to pass rigorous utility reviews and local AHJ inspections.
With deep domain expertise in NEC Article 690 (Solar PV Systems) and Article 705 (Interconnected Power Production Sources), I bridge the gap between your commercial or utility-scale PV array and the electrical grid.
What I deliver:
- Professional Electrical Single Line Diagrams (SLD) & 3-Line Diagrams
- Load-side and Supply-side (Tap) grid interconnection designs
- Medium-Voltage (MV) substation and step-up transformer schematics
- Comprehensive electrical calculations (Voltage drop, breaker sizing, conductor scheduling)
- Protection and metering layout mapping
Every drawing is crafted using professional drafting standards, minimizing review bottlenecks and accelerating your project timeline.

FAQ
Do you design for both supply-side and load-side grid connections?
Yes. Depending on your system capacity and facility setup, I can design compliant supply-side tie-ins (taps) under NEC 705.11 or load-side connections under NEC 705.12, including all required overcurrent protection.
Can you update the drawings if the utility company requests revisions?
Absolutely. Commercial utility reviews often include technical feedback. My packages include dedicated revision rounds explicitly designed to address utility comments and align the schematics with their requirements.
Will you provide the source design files?
Yes. The Standard and Premium packages natively include the fully editable vector source files (typically in AutoCAD DWG format) alongside the clean PDF engineering submittals.
