Solar cells

Spark Fun Electronics has some new 7 x 4.5″ 9V solar panels for $30 – “Packaged solar cell with barrel plug termination. This is a custom cell produced for SFE – not a small toy surplus item! This unit is rated for 8V open voltage and 310mA short circuit. We actually took a random unit outside and measured 9.15V open voltage and 280mA short circuit. Under ideal sun conditions (high-noon, clear sky) 310mA is very possible but will vary from cell to cell. We can even get 110mA from inside our office windows!”Link.

  1. What are you trying to say, Shadyman?

    A picture may be worth a thousand words, but one solitary “Word.” is useless. It conveys no meaning on it’s own and there is no supporting context. The addition of a verb and a few judiciously placed articles, pronouns, and perhaps an adjective or another noun would help your sentence construction immensely.
