Implementations of the disclosed subject matter may provide systems and methods of providing energy from a community solar energy generating system to a customer. The customer may have an account with a first energy utility, and the community solar energy generating system may be associated with a second energy utility. The first energy utility may be located in a first geographic area and both the community solar energy generating system and the second energy utility are located in a second geographic area. An allocation of energy produced by a community solar energy generating system may be determined for the customer based on energy usage based on the received utility account information, an energy output of the community solar energy generating system, and a credit rate. Information about the determined energy allocation and the credit rates may be shared between the second energy utility and the first energy utility.

A charging device disclosed herein includes an input port, an output port, and a relay circuit. The input port is electrically connected to an external power source provided externally and that is configured to be able to input direct-current power and alternating-current power from the external power source. The output port is electrically connected to an electrified vehicle and that outputs direct-current power to the electrified vehicle. The relay circuit relays electric power between the input port and the output port. The relay circuit includes a converter circuit that converts alternating-current power into direct-current power when the alternating-current power is input to the input port, and an input bypass circuit that causes direct-current power to bypass the converter circuit when the direct-current power is input to the input port.

A novel transformer circuit employing multi-axis windings around a large magnetic billet receives and amplifies the energy from a flux of energetic waves emanating from the sun and other celestial bodies and entities throughout the environment. A clean source of solar energy can be harvested with an energy density that is at least 50 times greater than photon-based collectors.

A method described delivers power to a first load and a second load from networked power plants. The method may include receiving a power delivery profile for the first load, receiving a power delivery profile for a second load, determining a power output capability of a first renewable energy power plant (REPP), and determining a power output capability of a second REPP.
