When you need this permit
- Permits required for all PV systems; submittal must include a completed General Permit Application

- Manufacturer's specification sheets for PV panels and inverter required
- Complete 3-line electrical diagram required, including system size (DC/STC), module specs, array specs, string count, conductor sizing, grounding, overcurrent protection, inverter AC output, and grid interconnection details (backfeed breaker rating, busbar rating, line/load side tap)
- Mounting/racking system details required: manufacturer spec sheets showing uplift capacity for 110 mph (3-second gust) wind load and 30 psf snow load, attachment fastener details, and a Colorado-stamped engineer's verification letter (custom racking requires a site-specific engineered design)
- Structural information required: roof framing member size/type/spacing, sheathing type/thickness, roofing layer count, flush vs. tilt mount, plus a Structural Evaluation letter stamped by an engineer
