Solar Site Analysis

Optimize your system performance by analyzing location and installation parameters

Location Selection

Selected Location:

Phoenix, AZ

Latitude: 33.4°N

Longitude: 112.1°W

POA Irradiance: 2200 kWh/m²/year

Data Source: NASA POWER (2024)

Installation Angles

33°
Optimal: 33°

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.

180°
N (0°) E (90°) S (180°) W (270°)
North-facing optimal in Southern Hemisphere

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.
