PV Gap

Gilbert Said:

I took out a solar power strip from my calculator, how do i use it for a mini fan?

We Answered:

Previous answer is correct, you probably won't have enough power to run the fan. Make sure you know what the polarity of the strip is, hook it up to a supercap in parallel, that is plus to plus, then use a switch to connect the supercap to the fan. That'll let you save up an hour's charge from the pv strip to run the fan for probably several minutes if the fan's small enough. The supercap has to be rated for the open-circuit voltage of the pv strip. There may be one in the dead calculator. You can use the pv strip as a battery charger, too, but you need to pay more attention to voltages ratings and the possibility of overcharge/self-discharge.

Kirk Said:

can i reuse a solar power mechanism from an old calculator?

We Answered:

Yes you can reuse the solar cells for other devices. The kind of things you can power are limited to the ratings of the cells. Also, you can use them in series or parallel to increase either current or voltage for the devices you want to power.
