A lot of institutions that are designed for Public Outreach, have by design, distributed premises.  ATMs or branches of a bank, Department Blocks in a University, etc.. are examples

We have designed a solution for such distributed organizations, where, each premise/department is powered by a small stand-alone Solar System, but they are all connected to a centralized command-  center which provides the status of the system at each premises on a  single screen, which can be used to keep watch on the status, troubleshoot and/or operate the system from a remote center.
