The systems assist in keeping the brightness levels intact without the need to have them cleaned on a regular basis. Engineers are even integrating solar panels with automated cleaning layers in smart-city planning efforts to enhance efficiency even more.

They are especially applicable to highways, industrial areas, and desert-prone regions. This would lower the maintenance cost and increase the long-term performance of these lamps in case of their implementation on a large scale. They further play the role of developing the city in a sustainable manner since they reduce the amount of resources consumed and provide a steady visibility at night to provide safer areas to the people.</span></span></div>
