Does anyone here know how to make mini solar panel?

I used to install solar systems on houses, but making one would be a challenge! Maybe if you google it in the hobby area you might find a couple cells! Then it's just a matter of building the case! I've recently seen the advances they've made and now have flexible ones, they are putting them on backpacks to keep your phone and Ipods charged! Good luck! tdemex

You can buy a broken one, all the pieces have around 0.55 V, so, you must link together them negative with positive, later, use a diode to prevent energy to return to the panel and buy a rechargable battery. (A wattage controller is recommended to avoid overcharging the battery).

Try to make series of 12V, each one with similar sizes, if not, you will not get all the amps)
