ELECTRICITY COST
What prevents cities from implementing new outdoor lighting systems? It is wise to assume that budgetary restrictions first and foremost.
Since solar LED lights are powered by off-grid solar energy source, the city’s electricity cost should eventually decrease. The energy savings from installing solar street lighting systems will enable new funds for implementing many other applications complementary to the smart city concept.
ENVIRONMENTAL IMPACT
Smart solar street lights do not have a negative impact on the environment. Since the sun's energy is used to power the system, no natural resources are depleted. LED lights have lower CO2 emissions than traditional globes. There will be fewer emissions by the entire solar off-grid lighting system and thus less pollution. The solar street light poles don't require a grid connection. This, in turn, reduces construction work and installation procedures, which translates into fewer risks of impacting the flora and fauna in the area.
