Solar irradiance is solar power density reaching Earth's surface. It varies by location, time, clouds, and atmospheric conditions.

चरण-दर-चरण मार्गदर्शिका

  1. 1Direct normal irradiance (DNI): beam radiation perpendicular to surface
  2. 2Diffuse horizontal irradiance (DHI): scattered radiation from entire sky
  3. 3Global horizontal irradiance (GHI): total arriving at horizontal surface

हल किए गए उदाहरण

इनपुट
Clear day, sea level, solar noon
परिणाम
GHI ≈ 1000 W/m² (AM 1.5 standard spectrum)
Peak theoretical

सामान्य गलतियां जिनसे बचना है

  • Using peak 1000 W/m² without accounting for clouds and seasons
  • Neglecting angle-of-incidence effects

अक्सर पूछे जाने वाले प्रश्न

How does altitude affect irradiance?

Higher elevation reduces atmospheric path, increasing irradiance. 1000 m altitude ~10% higher than sea level.

Why do solar panels need tilting?

Tilting captures more direct irradiance. Optimal angle ≈ latitude for fixed systems.
