How can I increase my solar generation in buildings if I want to opt for vertial solar installations (along the facade)?

If you want to increase the solar energy generation in vertical solar installations (solar panels aligned along the walls) in buildings. You can do the following things-

1. Optimise the orientation of the panels such as using south-, east-, or west-facing facades.
2. You can also opt for highly efficient solar modules to maximise generation from the same area.
3. Enhancing the reflectivity of surrounding areas, such as using light-colored pavements or walls, further boosts energy capture.
