Location Selection
Selected Location:
Phoenix, AZ
Latitude: 33.4°N
Longitude: 112.1°W
Annual GHI: 2200 kWh/m²/year
Installation Angles
Tilt Angle Guide: Optimal angle typically equals latitude ±15°. Steeper angles favor winter generation, flatter angles favor summer output.
Seasonal optimization: Latitude-15° for summer focus, Latitude+15° for winter focus, or adjustable mounting for year-round optimization.
Azimuth Angle Guide: 180° (South-facing) optimal in Northern Hemisphere for maximum sun exposure. In Southern Hemisphere, 0° (North-facing) is optimal as the sun travels through the northern sky.
Why it matters: Proper azimuth orientation can increase energy generation by 10-25% compared to east/west orientations.
Performance Impact
Recommendations:
- Tilt angle is optimal for this location
- South-facing orientation maximizes generation
- Consider seasonal tilt adjustments
