Abstract: A mounting system for mounting a solar panel assembly to a base assembly includes a panel support bracket, a base bracket and a clamp configured to exert a compressive force to hold the panel support bracket and the base bracket together. The clamp comprises a V-shaped clamp body that includes a pair of legs that are spring-loaded to oppose an approximation of the legs by an external compressive force. The clamp includes a pair of receiver slots, with each of the pair of receiver slots located on a corresponding one of the pair of legs. The pair of receiver slots collectively provides a clearance to admit the panel support bracket and the base bracket when the legs are compressed together.

Abstract: A photovoltaic power generation system and a method for controlling power balance are provided. The system includes at least two photovoltaic arrays, at least one power balance circuit and a power converter. Each of input ports of the power balance circuit is connected with at least one photovoltaic array, and an output port of the power balance circuit is connected with the power converter. The power balance circuit performs power transfer based on a difference between output powers of the two photovoltaic arrays to control a difference between powers of two output terminals of the power balance circuit to be within a preset range.

Abstract: The disclosed Infrastructureless™ Data Center is a green-on-green technology. In an embodiment, an example Infrastructureless™ Data Center includes an Infrastructureless™ base node including a photovoltaic (PV) panel assembly. The Infrastructureless™ Data Center further includes a variety of proprietary computing components attached to the Infrastructureless™ base node including some or all of compute, memory, network, power and storage assemblies that, when attached to the Infrastructureless™ base node, create an Infrastructureless™ Data System. Infrastructureless™ Data Systems of similar configurations can be grouped together to form Infrastructureless™ Clusters. Multiple Infrastructureless™ Clusters can be grouped together to form an Infrastructureless™ Data Center of any size. In some embodiments, the Infrastructureless™ Data Center is electrically self-sufficient, e.g., carbon neutral, and does not need to be connected to an external power grid. In other embodiments, the Infrastructureless™ Data Center is carbon negative and can supply unused electricity to an external power grid.

Abstract: An antenna array has a plurality of square or rectangular antenna assemblies. Each assembly includes a first antenna assembly surface with a solar cell and a second antenna assembly with one or more antenna elements. The antenna assemblies are interconnected without gaps therebetween to form a first contiguous array surface comprised of the first antenna assembly surfaces and a second contiguous array surface comprised of the second antenna assembly surfaces. The antenna assemblies are connected together by mechanically stored-energy connectors, such as spring tape, that self-deploy the array in space without the use of electric energy.

Abstract: A photovoltaic converter and a photovoltaic generation system. The photovoltaic converter is configured to electrically connect to a first photovoltaic module and a second photovoltaic module, where the first photovoltaic module includes a first positive electrode output end and a first negative electrode output end, and the second photovoltaic module includes a second positive electrode output end and a second negative electrode output end. The photovoltaic converter includes a current transformer and a power conversion circuit. The current transformer includes a magnetic structure, a first positive primary side winding, a second positive primary side winding, a negative primary side winding, and a first secondary side winding. The three primary side windings all pass through the magnetic structure and are spaced from each other. The first secondary side winding is wound around the magnetic structure. This reduces an occupied board area.
