Abstract: A control system for a technical plant includes control units at the plant to control, maintain and/or monitor the technical plant as well as a management system outside the plant to remote-control, remotely maintain, and/or remotely monitor the technical plant. The control system further includes a data link between the management system and the control units, the control units being controllable and configurable by having the management system remotely access them.

Abstract: A modular apparatus and method for safely and securely storing horizontally stacked photovoltaic modules includes a plurality of molded, plug-in components. Each of the components has an inwardly facing load-bearing support portion configured to abuttingly supporting thereon a photovoltaic module, a lower portion with at least one downwardly extending projection, and an upper portion with at least one cavity shaped to closely receive therein said projection on a vertically adjacent one of said components, such that the components are stacked in a vertical column to support portions of the horizontally stacked photovoltaic modules.
