Oops, typo, obviously.

So, assuming 30mA to be the drain, the question is whether or nor a 10w
panel can produce enough watts for enough hours to produce 8.64
watt-hours in a 24 hour period. If it could produce 2 watts for 5 hours,
that should be enough.

It comes down to where it is sited.

Yeah. Kenya is a good place at this time of year.
