I had the idea before you all. I was 2 years old at the time.

I don't know very much about these things but hopefully someone will correct my errors ....

The voltage will vary with light level. (Of course)
The voltage will drop rapidly with increased current draw.

It would be quite expensive to get a large panel to supply enough current. It would need to supply ~3V more than required to keep the regulators happy.

How about trickle charging a battery instead?
I suppose that depends how long you listen to your music.

Hi, Sonusthree

you must be pretty genius at 2 yrs old.

well it would need some sort of regulator for sure.
actually my idea is to power the solar panel from incandescent lamp.

so, no rectifier noise, no ground loop from supply, no transformer noise.

Hi nicoch46,


"from solar you note advantage on sound?"


I think we haven't tried that yet.
