The present disclosure relates to a day-night photovoltaic system. More specifically, power supplied to a solar panel from a DC power supply part is output as a final output power PV together with power produced by the solar panel during the daytime, and is output as the final output power together with an ultra-high frequency wavelength generated by the sun explosion and induced to the solar panel during the night time. This provides the effects of stably supplying the power not only during the daytime but also during the night time.

Power generation devices and methods for use with toilets is disclosed. A number of power generation devices are provided that can be used in combination to power various features in a toilet which will be particularly useful for portable toilets that are off the grid. The power generation devices and methods include, for example, using a cell battery inside a toilet water source, a wind turbine, solar panels, and piezoelectricity. The features include, for example, lighting up the toilet with light-emitting diodes (LEDs) to make it easier for users to find the toilet, an audio/video setup for entertainment, and a toilet status light indicator to let the next user know when the toilet paper is out.

The system includes a first DC/DC converter connected to a PV panel and to one or more energy storage modules, and a second DC/DC converter, connected in parallel to the PV panel in a string of PV panels of a PV installation, wherein the second DC/DC converter is configured to operate as an optimiser and execute a maximum power point tracking algorithm (MPPT) to determine the maximum power output of the PV panel of the plurality of the PV panels in the string.

Disclosed are various embodiments for optimizing energy management. A quantity of renewable power that will be generated by renewable energy generation sources can be forecasted. The energy demand for a building or a cluster of buildings can be forecasted. A pricing model for buying energy from a grid can be determined. A quantity of energy to import from the grid or export to the grid can be scheduled based on the quantity of renewable energy forecasted and the state of charge or health of battery energy storage system, current and future operations of building HVAC, lighting and plug loads system, the forecasted energy demand for the building, and the pricing of the energy from the grid.

Apparatuses, systems, and methods of use for a generator is disclosed. In one embodiment, the generator has a stator and a rotor and a first plurality of magnets coupled to the rotor and a second plurality of magnets coupled to the stator. An external magnetic housing may be coupled to an input shaft of the generator or surround the generator itself. A first layer of magnets produce a rotating magnetic field and a second layer of magnets create a static magnetic field, whether such magnets are in the generator itself or within an external magnetic housing. The disclosed generator increases the mechanical power inputted into the generator, which then produces an increased output of the generator.
