What checklists are needed to inspect for quality assurance in solar designs?

The specific items to inspect for Quality Assurance (QA) in US solar permit designs will vary depending on the local authority and project size. Still, generally, they fall into these categories:

1. General Permitting Requirements:

•  Completeness of the application: Ensure all necessary documents are included, such as site plans, electrical schematics, and structural calculations
•  Compliance with local codes and standards: Verify the design adheres to relevant electrical, building, and zoning codes

2. Electrical Design:

• Electrical safety: Check for proper grounding, overcurrent protection, and wiring diagrams that meet code requirements
• System sizing and performance: Ensure the system capacity aligns with the permitted size and estimated energy production is accurate

3. Structural Design:

• Load calculations: Verify the mounting structures can withstand wind, snow, and seismic loads specified in the local code
• Roof compatibility: Ensure the chosen mounting system is suitable for the roof type and material.

4. Additional Considerations:

• Environmental impact: Some localities may require assessments of potential shading impacts or glare from the panels.
• Fire safety: Specific fire clearance requirements for solar installations might exist.

Remember, this is not an exhaustive list, and it’s crucial to consult the specific requirements of the local authority involved in the permitting process.
