I finally got round to do some analysis on the small 5W and 8W solar panels I have been using for tendering car batteries. The conclusions is they are more or less useless. Unless facing the sun directly, the power output drops to next to nothing. At mid-day, with the sun at an angle to the panels, I got 25mA and 40mA respectively. Neither could supply the the car's sleep requirement. The situation would improve marginally in the summer when the sun is at less of an angle. My original hope for a panel to charge the battery sufficiently in the summer and carry it over for the winter was a pipe dream.
