we have to conduct an experiment regarding conversion of energy…it involves converting solar energy to electrical energy…we were given solar plats…how the experiment could be conducted and what could be the reasonable variables??

Seems like no matter where I look everywhere is more expensive for certain panels and products how do they manage to sell them so cheap are they really factory direct or wholesale or do there products come second hand?

I live in a very cold climate and want to make a home-made solar heated bird bath.

Ideas?
Update:

My real reason is to provide drinking water that isn’t freezing cold. The birds that do not migrate seem to get very thirsty when everything is below freezing for days and days (no liquid water out there…)

People in my neighborhood feed them, but no one seems to be watering them.

I have seen our winter birds (cardinals, sparrows, etc) actually bathe in warm water I put out. It’s gotta be up to them if that’s a good idea….
The real object is drinking water, not bathing.
