Alien's

We are a Media Buying Unit, and we're investing too much money in lighting our Unipoles since they function on electrical system.
What we need is to decrease this cost through buying rechargeable battery system or solar light system.

-We have around 500 Unipoles:
Size: 14 * 4m
Shape: Triangle(3 Faces Unipoles), square (4 Faces Unipoles), 2 Faces Unipoles, 1 face Unipole
In order to lighten a Unipole, we need 4 projectors (400 watt metal highlight/each)
The question is: How much will it cost us to light it with rechargeable battery system LED light or solar system light.

-We also have around 1000 billboards
Size: 4 * 3m
*** In order to lighten a 4*3m Billboard, we need 4 neon light (60 watt/each)
The question is: How much will it cost us to light it with rechargeable battery system LED light or solar system light.
Kindly find attached the Unipoles' pictures, the projectors' pictures we use. We need the same but solar system light or LED light batteries. We need the prices by Unit.
