I plan to look into this further but from their web site:
"In a Smart-Energy Network, each and every electrical device drawing power from the grid, large or small, acts as an intelligent agent communicating operational status to the local and regional power utility, collecting information on grid conditions and responding in ways that increase energy efficiency and reduce power infrastructure requirements, ..."
To me this means you need a "smart meter" and a "smart grid" so your equipment can "talk" to the grid. Which means permits, etc. Helco's big argument is that they do not have a smart grid and can only accept a small amount of alternative energy. So upgrade the gird already!
I have installed an Enphase system. These microinverter systems, especially as costs drop, seem highly practical.
edit: Not sure on this but: If you have an old style meter with the rotating wheel you could connect something like this to it and energy you produce would reduce your cost. If you have a newer digital meter you will be paying Helco for the energy you produce.
edit: I wonder how this will meet NEC code requirements for grid tied system disconnects?
