  • I mean just that. Rows of solar panels on flat roofs or ground mounts are spaced just far enough apart that when beam illumination hits them that there are normally no shade from one row to the next… but that assumes that the light is coming from a well-known band of locations in the sky where the sun is. Strong differences in illumination cause PV to work as well as the lowest irradiance level, and in the case of beam-reflected irradiance from a rapidly moving source location that won’t be restricted to “where the sun usually is” and because there will basically be no significant diffuse irradiance from the satellite mirrors the arrays will frequently be suffering from unexpected shade which will make them terrible at converting the reflected light.


  • Beside the obvious diurnal health impacts, solar PV doesn’t work well when shaded and relies quite a bit on diffuse light to keep the array producing during those edge of day times when it is economically hard to make the modules spread out enough to avoid direct sun shading. Pointing reflected beams from arbitrary directions in the sky turns out to be very likely to create unusual shade lines that will render the light nearly unusable by the panels.

    Then of course since they are planning to locate the reflectors in high-angular-velocity low earth orbit even if the angles are briefly conducive to power conversion it won’t last very long and then some fossil fuel generator is going to have to bobble their throttle to fill in the gaps… which is the worst possible scenario for using solar power (equal amounts of fossil generation as PV needed so no displacement).


  • Nothing stopping you. But we have no way to know if we are aiding you in circumventing your professor’s rules… shouldn’t they be earning their keep and providing sufficient learning support for you to pass the class?

    From my own perspective, I like ruminating on questions that are beyond the scope of a CS class… especially in a public forum where my mistakes can (hopefully not in a toxic way) be corrected so I can learn also. But coming up with yet another way to describe why one basic sorting algorithm is faster than another just seems redundant. It may be new to you, but homework is supposed to build your vocabulary not ours.
