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.
