The photovoltaic system can be recouped in 3-4 years .
When the solar elevator is installed in a building, having the photovoltaic system upgraded to a Building Evacuation System (BES), then this can be recouped even in 3-4 years. In any case, the advantages cannot be measured in economic terms only. How to rate financially an ABS system in a car if for once, it saves your life? The solar lift is not just an operating system, but at the same time is a safety system.
The solar lift has zero footprint on the environmental radar. This simply means that solar lift is a 100% “green” product. If we install 1,000,000 solar lifts in an urban center, the environment will have no effect.
