How come these things are not taking off here or anywhere?
I think its fear of the unknown and the lack of REAL numbers to understand the “payback” on these systems.
The best use of solar powered systems in the US is for covered parking. They can do many things:
cover cars (protect people from the elements)
collect the suns energy (send electricity back to the grid)
reduce maintenace (snow)
collect water (if designed properly)
Reduce Heat Island effect (what’s that? Just ask)
