Yes, you can often expand the system by adding more solar panels or batteries if your energy needs change.

A Home Balcony Solar Energy Storage System can be installed in both apartments and houses, provided there's sufficient balcony space and proper permissions.

During cloudy periods or at night, your home can draw power from the batteries. If the batteries are depleted, you'll still have access to grid power.

The required space depends on your energy needs and the number of solar panels. Generally, a few square meters can be sufficient for a small installation.
