Streamline Solar Permitting with One Place Solar  

As solar adoption increases across the U.S., contractors face growing pressure to complete installations quickly while staying compliant with evolving codes. The solar permitting stage remains one of the biggest bottlenecks, as AHJs tighten requirements, and even minor documentation errors, non-compliant schematics, or missing structural data can lead to costly delays.

At One Place Solar, we eliminate these setbacks with high-quality, fast-turnaround solar permit design services for residential, commercial, and utility-scale projects. Our plan sets are fully engineered, 100% NEC-compliant, AHJ-ready, and prepared by licensed professionals with nationwide coverage.

Why Solar Permit Design Matters  

Solar permitting isn’t just paperwork; it’s a crucial technical phase that determines whether your project gets approved, delayed, or rejected. AHJs require detailed documentation to verify safety, code compliance, structural integrity, and overall system performance.

Common challenges solar contractors face include:

• Missing electrical or structural components in submissions
• NEC/IRC/IBC violations such as incorrect conductor sizing, grounding, or load calculations
• Multiple AHJ revision requests due to unclear layouts or incomplete documents
• Installation delays caused by low-quality or non-compliant plan sets

To avoid these setbacks, One Place Solar delivers fully engineered, detail-rich PV plan sets built to meet national codes as well as local AHJ requirements.

Each plan set includes:

• NEC-compliant electrical line diagrams and three-line diagrams
• IBC-based structural load calculations
• Wind, snow, and regional load verification
• Mounting, racking, and equipment layout drawings
• Utility interconnection documentation
• Safety placards, labelling templates, datasheets, and BOM

Our goal is simple: submit once, get approved fast.

Our Solar Design Process: Speed Meets Precision  

Our process is built for high accuracy and speed, ensuring installers can scale efficiently without sacrificing compliance.

1. Project Assessment  

We begin by reviewing the project’s roof layout, site survey data, shading reports, drone imagery (if provided), and utility requirements. This ensures a tailored design that aligns with AHJ standards and your installation goals.

2. Engineering & Drafting  

Our engineering team develops detailed, code-compliant plan sets that include:

• PV layout drawings (rooftop, ground-mount, carport, or hybrid)
• Conductor sizing, over-current protection, and grounding details
• Stringing configuration and inverter selections
• Datasheets for all components
• Safety and labelling sheets

3. Quality Assurance  

Every plan set undergoes a rigorous dual-stage engineering review, checking for:

• NEC Article 690 compliance
• Structural alignment with IBC or local building code
• Compatibility with AHJ permitting requirements
• Utility interconnection requirements

4. Fast Delivery  

With optimized workflows and a nationwide network of engineers, most plan sets are delivered within 1–2 business days, significantly reducing your time-to-install.
