I've got a 5v Peltier chip. What kind of and how many solar cells 4.5v 18mA do I need per 1 chip? I found these cells online on dealextreme, but there are also other different types. I'm lacking a basic knowledge in electronics, so I'd like to get an advise on how you make that math. Also if you can point to some quick online learning tutorial on that issue, it would be great. Thank you.
Update. Ok, I found online two links, the video is not very helpful because there is no explanation about what kind of solar cells and controller etc are needed, and the second one where the guy doesn't describe much about the 'solar' part of his hardware.
But please - if you are reading this - please add your valuable input!
Edit: The cooler is a 12 Vdc heater / cooler assembly utilizes a Peltier device to create heat on one side and cold on the other. Driven by a 40 mm square Peltier thermoelectric heat pump, it operates on 13 Vdc @ 5 Amps. Operating at 13 Vdc, we measured the hot side at 190 Deg. F and the cold side at 55 Deg F.
