I'm not entirely sure how this works or what you mean by pulsed dc coming from a solar cell put under a florescent or incandescent light.

He means that a solar cell outputs straight DC under the sun, but fluorescent lights flicker at 60hz, too fast to detect by the human eye, although a common cause of building sickness, especially in Europe where grid power is 100hz.

Solar panels are designed to emit straight dc, there is no A/C rectifier in solar cells, and definitely not at 60hz...

In the experiment I did I used a single solar cell each time (about 5 times),I did hear a 60hz hum each time. But never used a solar panel.I can only say try it and see what happens.I put a solar panel on my kitchen floor one night under fluorescent lights and got about 9 volts on a voltmeter.But I did not think to hook a speaker up to it.If you get a hum out of it you are getting pulsed DC(sinewave only).Good luck.Triffid

I only used fluorescent lights in my experiments.No others!Triffid

I had a thought,if solar panels don't work here ,you could always hook up 3 regular solar cells or more in series to get the voltages you want.Triffid
