Peak Sun Hours Calculator

Calculate peak sun hours and solar insolation for your location based on latitude, season, and weather conditions. This helps you optimize your solar system's performance.

Enter your location's latitude (positive for North, negative for South)
Select the current season
Select typical weather conditions
Enter your location's altitude above sea level
Enter your solar panel tilt angle (0° = horizontal)

Typical Peak Sun Hours by Region

Region Summer Winter Annual Average
Equator 6.5-7.0 6.0-6.5 6.5
Temperate 5.5-6.5 2.0-3.0 4.0-5.0
Polar 4.0-5.0 0.0-1.0 2.0-3.0

Factors Affecting Peak Sun Hours:

  • Geographic location (latitude)
  • Season and time of year
  • Weather conditions and cloud cover
  • Atmospheric conditions
  • Altitude above sea level
  • Local terrain and obstructions
  • Air pollution levels

Optimization Tips:

  • Adjust panel tilt angle seasonally
  • Consider tracking systems for better exposure
  • Minimize shading from nearby objects
  • Account for seasonal variations in system design
  • Regular cleaning to maintain efficiency
  • Monitor local weather patterns
  • Consider micro-climate effects
