Can solar panels work on artificial light or do they need sunlight?
Sure, they’ll work with any light. A solar calculator works in a well lit room. This isn’t exactly an efficient way to run things, though, since it takes far more energy to generate the lights than you can recover. Sort of like growing marijuana indoors. But yes, if you have a bunch of stolen solar calculators that you need to use, but are afraid to take outside, you can have a little computation farm in your basement where you keep them working under bright light.
