Tip: The battery needs a couple hours of sunlight to recharge. Do not expose duration shadows.
I have only once set the house number a day in the sun and only then hung up. In the description though is that is pre-charge the battery, but after that I did not leave me.
Contraindications:
When disconnecting the battery Entladeschutzstreifens the contact of the positive pole I came off. He is, however, easily connect it again. Please deduct only if the lid is open. I fixed him with a drop of glue. This also explains maybe that when the clerk reviews the solar lamp is not lit even after 3 weeks.
