Solar PPA Ground Lease Protocol

Commercial Solar Carport Lease & Interconnection Protocol

🚗 Parking Lot Operations & ADA Access

✅ Vertical Clearance Mandate: Minimum 9.5ft clear height under cantilever beams (14.0ft for delivery/fire truck lanes).
✅ ADA Stalls Preserved: Solar structural caissons cannot obstruct van-accessible parking aisles or curb cut ramps.
✅ Under-Canopy Lighting: 150W LED wet-location canopy luminaires maintain 5.0 foot-candles minimum night illumination.

⚡ Utility Interconnection & Transformer Pads

✅ Dedicated Pad-Mount Transformer: 480V 3-Phase step-up transformer installed adjacent to primary utility switchgear.
✅ Bifacial Solar Module Guttering: Water management channel flashing prevents heavy rain runoff cascading between cars.
✅ Rapid Shutdown (NEC 690.12): Module-level power electronics (MLPE) ensure rapid DC voltage de-energization in emergency.

❄️ Snow Shed Guards & Ice Safety

⚠️ Snow Deflector Cleats: Heavy aluminum snow retention brackets installed along lower canopy eaves.
⚠️ Thermal Expansion Joints: Structural steel purlin runs include slotted expansion bolt holes every 120ft.
✅ EV Cable Management: Retractable spring-loaded overhead cable drops prevent cord damage from snow plows.
