Any paper reference (which I can cite) which shows the solar irradiance/intensity (W/m^2) available at shaded locations like shaded side of buildings, underside of bridges , or locations receiving indirect solar radiation?
Reason: I plan to show the energy harvesting capability of a traditional solar cell when it is kept in shaded regions like shaded part of buildings, underneath bridges, etc and still harvest energy. I have assumed 30 W/m^2 - 100W/m^2, if I get citable sources then that would be much better.

I recommend that you don't try to quantify this. Shaded sunlight is just SO VARIABLE in intensity and spectral composition that its effect on PV is too unpredictable. Just assume 5% of full power averaged over all the various situations. And note that most solar arrays don't like mixed full sun and shade on them at the same time. And if you find at the end of your calculations that an input of 5% rated power into the load is insignificant in most applications, you have come to exactly the same conclusion as I did 10 years ago. Nothing has changed in the meantime!
Hello,
You may use the following android app for studying the shading zones under various scenarios. The app uses simplified models that may not sufficiently accurate for your study.
