Solar Irradiance ಅನ್ನು ಹೇಗೆ ಲೆಕ್ಕ ಹಾಕುವುದು

Solar Irradiance ಎಂದರೇನು?

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

ಹಂತ-ಹಂತದ ಮಾರ್ಗದರ್ಶಿ

  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

Worked Examples

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

Common Mistakes to Avoid

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

Frequently Asked Questions

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.
