Energy converters are monitored to ensure that they are operating at acceptable levels. An expected output is predicted using mathematical modeling and compared to the actual output generated by the energy converter. When the difference is above a predetermined threshold, the level of underperformance, along with other parameters, are used to determine a possible cause of underperformance and actions that can be taken to increase the output to acceptable levels. The cause and actions are transmitted to personnel, who are dispatched to service the underperforming energy converter. By centrally locating the mathematical modeling, monitoring, and dispatching, multiple PV modules can be managed from a remote location. When monitoring photovoltaic modules, an irradiation sensor employs multiple photosensors oriented to detect not only the normal components of sunlight but also directional, diffused components of sunlight, thereby increasing the accuracy of the mathematical modeling.

The back-up structure of a parabolic dish antenna, which supports its reflecting surface, is formed in this invention by preloading its radial and circumferentially placed straight structural members and hence it is termed as preloaded parabolic dish antenna. Such a preloading results in considerable reduction in its weight and also to the effort involved in its assembly. The back-up structure of the preloaded parabolic dish antenna is made of a central hub, an assembly of a suitable number of elastically bent radial structural members connected rigidly to the central hub and to the same number of straight structural members which are connected to the tips of the radial members at the outer rim of the dish and also to straight bracing members placed circumferentially at intermediate locations, which are all tensioned to specified prestress values in the absence of wind loading. The outermost rim members placed at the periphery of the dish form the aperture of the dish. The backup structure of the preloaded parabolic dish antenna is given the parabolic shape by fixing the radial members at a suitable inclination angle and location at the hub and by applying an appropriate force with a normal component at their tips so as to bend the radial members elastically such that their curvature becomes approximately the same as that of the parabolic curve between the hub and the peripheral rim point. The invention incorporates a suitable rigid connection of the elastically bent radial members and other structural members in order to store sufficient initial elastic energy in the back-up structure of the dish for resisting gravitational and static and dynamic wind forces on the parabolic dish antenna for the survival wind condition at the antenna site. This configuration also reduces moment of the wind forces and torques on the mounting tower and gear drive system of the dish antenna. This invention is also applicable to structures of geometries other than that of the parabolic dishes. The method of constructing the preloaded parabolic dish and attaching reflector panels of lightweight is also disclosed.The preloaded parabolic dish antennas are useful in microwave communication, satellite communication, radar, radio telescope and other similar applications for receiving and / or transmitting radio waves.
