Hi Dan,
A 5" x 5" solar panel can put out about 150 milliamps at 6 volts in
full sun, ~1 watt), which is even enough to run a BS2SX. However, in
shade the same panel will only generate a couple of milliamps, just
enough to run the original BS1 but not the BS2. In a room with
adequate reading light it will be less than 0.5 milliamp.
Systems using solar panels usually incorporate a rechargeable battery
to carry the system thru the night or dark periods. All the better
if you can use the SLEEP and NAP commands to get a much lower average
current.
