  • SOLAR CELL OR SOLAR PANEL ENERGY EXTRACTION SYSTEM
    Publication number: 20210376789
    Abstract: A photovoltaic system having at least one solar cell and a secondary direct current power supply connected to the at least one solar cell. The secondary power supply is configured for constant voltage operation to input power to the photovoltaic cell to maintain operation of the solar cell at or near an optimum voltage working level for the solar cell.

  • Hybrid solar power supply control system
    Patent number: 10790672
    Abstract: Embodiments of the present invention provide a control system for a hybrid solar power supply system, in particular for direct current (DC) power supply. The hybrid solar power supply control system includes a power arbiter and a power controller. The power arbiter unit is connectable to a photovoltaic power supply and one or more other power supplies and comprises circuitry to connect the input photovoltaic power supply and other power supplies and combine power from one or more power supplies for direct current (DC) output, and transition between power supplies based on the available input power from each power supply. The power controller is configured to vary the apparent load applied at the DC output to control the power drawn from the one or more power supplies.
