Are vehicles like the Volt a key to solar power?

Makes home solar power more cost - effective?

More than 40 US utility companies have partnered with GM to prepare for the Chevy Volt and its impact on the US electric grid. Much of this conversation has focused on smart grid technology, which is a worthy conversation. Yet, it is still a conversation driven by utility control of the grid and all of its energy sources.

Shouldn't a large part of this conversation also be focused on alternative energies, especially solar power? Aren't vehicles, such as the Volt and its large lithium battery pack, excellent ways to maximize home solar power?

Should not battery powered vehicles become a driver of more distributed energy grid solutions?
