| (...) Thanks. I just visited the Edmunds Scientic Page and they said their solar panels can be wired in series. The thing I need to know now is how many volts and how many amps is appropriate for powering the Rcx. I assume 9 volts. But is 12 volts (...) (25 years ago, 9-Jul-99, to lugnet.build)

| Not a direct question. In general. Each photo cell will give a certain amount of voltage and current capability. If a cell is rated at .5 volts, that is generally under very well lit/bright conditions, which are unusual. It also assumes the panel is (...) (25 years ago, 9-Jul-99, to lugnet.build)
