I have two solar panels and I have measured that they produce V by themselves. I am trying to generate .5V, but whenever I hook them up in parallel I get something like .02V. What it happening?
. You want series, not parallel. (Add the voltages. Coonect '+' of the first to '-' of the next, and take your feed from the extreme ends.) 2. if you parallel them and you get less voltage than one alone, you got your polarity crossed up and are reading the difference between them.
You are probably wiring them incorrectly: with the positive on panel A connected to negative on panel B; and the negative on panel A connected to the positive on panel B. If you want then connected in parallel, connect the positive on panel A to the positive on panel B and the negative on panel A connected to the negative on panel B. But you will only get vdc. You can't get .5 volts from two volt sources. You can get 2 volts by connecting the panels in series.
