Abstract: A vehicular electricity generating canopy appliance includes a rectangular framework forming a vehicular chassis with solar panels, support apparatus for repositioning panels, auxiliary wheels, a trailer dolly for towing, and an electrical system connected to an inverter supporting optional Vehicle to Grid (V2G) operations. The vehicular canopy is designed to be movable and storable to protect the panels during adverse weather conditions.

Abstract: The present invention relates to resiliency in photovoltaically produced power generation and utilization. This invention comprises a system of elements that combine to minimize the cost and complexity of a backup-capable solar power system. An element of this system is a prior-art balancer-based photovoltaic panel power optimizer whose power electronics are time-shared to allow an array of battery modules to power or provide supplemental or surge power to an inverter. Further elements of the system provide for rapid and low-cost installation, reliability, and easy and safe maintenance.

Abstract: A flyback converter has a sub-nanofarad capacitor disposed between the primary winding and the secondary winding of a transformer included in the flyback converter. A controller in the flyback converter co-optimizes the switch period and width such that the flyback converter operates substantially at peak efficiency via the use of a novel set point and control-signal. A model of global optimal control is provided via a novel characterization and analysis method.

Abstract: Various techniques are employed alone or in combination, to reduce the levelized cost of energy imposed by a power plant system. Solar energy concentrators in the form of inflated reflectors, focus light onto photovoltaic receivers. Multiple concentrators are grouped into a series-connected cluster that shares control circuitry and support structure. Individual concentrators are maintained at their maximum power point via balance controllers that control the flow of current that shunts this series connection. DC current from clusters is transmitted moderate distances to a centralized inverter. The inductance of transmission lines is maximized using an air-spaced twisted pair, enhancing the performance of boost-type three phase inverters. Cluster outputs are separate from individual inverters in massively interleaved arrays co-located at a central location.
