There is something in front of the solar panel (e.g : a tree, a balcony, etc.) would the solar-powered screen work normally?​

Except if the solar panel is completely shadowed, the solar panel will get enough energy to recharge the battery. To be 100% sure of the performance of the system, use the Somfy Solar App.
