    Why Solar Carports?

    Solar carports represent one of the most practical applications of distributed solar energy. By covering parking areas with solar panels, businesses can generate clean energy, provide weather protection for vehicles, and integrate EV charging infrastructure — all while utilizing existing developed land.

    Design Considerations

    Structural Engineering

    Solar carport structures must meet strict engineering requirements:

  1. Wind load ratings: Designed for local wind speeds (typically 100–160 km/h)
  2. Snow load capacity: Northern climates require 1.5–3.0 kN/m² snow load ratings
  3. Vehicle clearance: Minimum 2.4m clearance for standard vehicles, 4.2m for trucks
  4. Column spacing: 5–6m typical spans to accommodate standard parking layouts
  5. Foundation design: Drilled piers or spread footings based on soil conditions

    6. Module Layout

  6. Tilt angle: 5–15° for optimal energy yield and water drainage
  7. Orientation: South-facing preferred; east-west arrangements work for wider structures
  8. Coverage ratio: 85–95% panel coverage maximizes generation per square meter

    9. EV Charging Integration

    Solar carports are ideal platforms for EV charging:

  9. Level 2 chargers (7–22 kW): Suitable for workplace charging during business hours
  10. DC fast chargers (50–150 kW): For retail and public charging applications
  11. Smart charging: Load management ensures solar self-consumption priority
  12. Battery buffer: Adding BESS smooths solar variability and enables fast charging without grid upgrades

    13. Project Economics

    A typical 200-space solar carport (approximately 500 kW):

  13. Installation cost: €800–1,200/kW including structure
  14. Annual generation: 500–750 MWh depending on location
  15. Simple payback: 5–8 years with self-consumption and EV charging revenue
  16. Additional revenue: Advertising space on structure, covered parking premium
