For example, solar panels that are in east and west generate less energy when facing the equator. A solar panel requires tilting towards the sun while producing energy. Optimizing the tilt angle provides ways to inverse the efficiency as well as energy production. Buildings that have a flat roof can benefit a lot from the extra costs.

4. Battery
