Diane,
BEL probably told you that they are running AC cables. The frequency of AC (Alternating Current) cause a bit of heat, if they bury the cables it is best to have a metal sheild to protect it from damage. This will cause the heat to be isolated around the cable and you will lose power. You can run this system for short distances, like CC, but not over long distances.
The cables I was suggesting are DC (Direct Current). Wind and solar generators produce DC power so burying these cables is no real issue. Then each home would have an inverter, something they will have to have anyways, at the connection to their home.
BEL also could have been concerned about the water table as well, but that is why you have the metal outer layer to protect it.
All and all I think Ron will have his own large island for quite awhile.

at least until I get there.
Dane, How much do you need for the solar panels on the school?
