Fraction solar power due to UV

AI Thread Summary
The discussion centers on the fraction of solar energy attributed to UV radiation and its impact on solar panel efficiency. To determine the energy loss without UV frequencies, one must integrate the spectral density specifically over the UV wavelength range. Resources like "Fundamentals of Heat & Mass Transfer" by Incropera & DeWitt are recommended for further understanding. The calculation can be performed independently by applying the appropriate integration methods. Understanding the role of UV in solar energy capture is crucial for optimizing solar panel performance.

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.
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Free fall of person in a sled to direct horizontal motion by atmospheric resistance'

Let there be a person in a not yet optimally designed sled at h meters in height. Let this sled free fall but user can steer by tilting their body weight in the sled or by optimal sled shape design point it in some horizontal direction where it is wanted to go - in any horizontal direction but once picked fixed. How to calculate horizontal distance d achievable as function of height h. Thus what is f(h) = d. Put another way, imagine a helicopter rises to a height h, but then shuts off all...
