"Use it or loose it".

Running the laptop with a SETI@Home load to pring total system load to ~50W
(laptop a little over 30W) seems to encourage the conbtroller to pass on energy
that it would not otherwise be able to put into the battery.

Energy demand for this SETI@Home job estimated at ~75Wh.

Energy captured from the main (550Wp) array ~600Wh today.
