Fraction solar power due to UV

[robin257]

Hello,

I was wondering what fraction of the energy delivered by the sun is due to UV-radiation. For example, when I have a solar panel which "catches" 1kJ of solar energy. What will happen if there would be no UV frequencies in the solar spectrum? How many percent less energy will I capture? Can I calculate this myself?

Thanks in advance

You would integrate the spectral density over just the wavelength of UV instead of all wavelenghs as is usually done. See Fundamentals of Heat & Mass Transfer, Incropera & DeWitt or any other good undergraduate heat transfer textbook.
