CarloSW2 - I'm sure you can leave that panel directly connected to the battery. I have a similar slightly larger panel - 15 watt, 1 amp - and it's been supporting my near dead starting battery for more than a year, directly connected.

Why is it near death? Because I ruined it in 2006 with multiple deep discharges when I first started experimenting with a charge-depleting 12v approach! It has very little capacity now, and the panel is just delaying the inevitable.
