I'm curious to know if the small solar panels on a calculator (ie TI-32) could produce a voltage similar to what is used in a single-use (disposable) camera, approximately 4V.
It isn't Volts that matter if you're trying to put the calculator solar panel on the camera. It would be the amps. The calculator's solar panel will put out however many volts or very close to what the battery puts out. If you want you can test it out with a Volt/Ammeter. You see, those cameras use 2 double A batteries. They are going to put out a higher current than the small dime shaped battery in the back of your calculator; a higher voltage perhaps too. Those disposable cameras have a photo flash capacitor in them that has to charge. You can hear them charge up when you tell it to turn on the camera's flash. Sounds like a winding then the little orange light comes on. That light means the capacitor is charged. You SHOULDN'T be able to change out the batteries in the camera with a solar panel from a calculator without having to wait days for that flash capacitor to charge. Sorry. EDIT: HOWEVER, you can take multiple solar panels and wire them in a parallel circuit to get more current(amperes) or wire them in a series circuit to get a higher voltage. If you were to do this you could power whatever you wanted with them. Even your house if you were to get a rectifier to convert the power from DC to AC.
