I run a similar toy system with a 180w panel and it makes about 110wh a day on an average from march to October - due to a similar bad position the monitoring plug would use more power than the panel makes the rest of the year :P

It runs an inverter and offsets my electricity use.

I plan adding a battery this year but my MPPT charger has been stuck in Hannover for 3 weeks now - I suspect a customs issue.
