I contacted Vergona-Bowersox Electric, Inc. today and this is what they told me.
Shaka currently has an open-ended contract to install at at least 30 of these 10 kWh systems. The contact is open-ended and as more schools become ready for installation the contract may be extended.
Shaka is currently installing these systems and is scheduled to have the first 4 systems installed by the 31st of December.
