for people who dont work: most people get off at: 8am or 9am and go about their daily lives...Come home at 4 or 5....But just so you know...From: 9 am or 10 am to 4pm or 5 pm there is 6 hours....So your day is only: 6 hours...plus 1 hour stuck in traffic going whever you go, and 1 hour coming home...So is 4 or 5 hours....by 6pm when night falls everything shuts down in most places...

I was thinking....Use tall buildings of cities put solar pannels in Tall buildings [rent their roofs] and the energy goes to streets, light posts but using brighter bulbs to really brighten up the night...

Then do you see all the: Axels from OLD SALVAGE cars well those axels could be used as, STREETS LIGHT POSTS, their iron could be melted and united and make streets light posts...

you could also create a rectangular thick in height block base and have the axel light posts in the middle of it and iluminate dark areas they dont have to be tall either, like a plant in a huge vase...

but make the lamp part of streets light post make the lamp part, circular, that way it, brightens up more area...
