  • Patent number: 11494530
    Abstract: One example includes a method for generating a solar farm design. Geographic map data defines geographic features and boundaries of a geographic region. A solar panel block library that stores virtual solar panel block types is accessed. Each of the virtual solar panel block types corresponds to a design of a respective solar panel block that includes solar panels, an inverter, and an access road, and each virtual solar panel block type includes predetermined dimensions and a predefined output power rating. An array of a virtual solar panel block type to fit within the geographic features and boundaries of the geographic region on the map is generated based on the dimensions of each of the virtual solar panel blocks in the array. The array is iteratively modified to optimize a criterion of the solar farm design, and the design is stored in a memory for subsequent solar farm installation.

The voltage sensor level shifts the provided voltage, and buffers the resulting level-shifted voltage. The buffered, level-shifted voltage is provided to a tracking analog-to-digital converter (ADC) for digitization. The buffered signal provided to the tracking ADC has a high current capability, such that the voltage input to the tracking ADC may quickly converge before the tracking ADC outputs a digital value for the sensed secondary-side voltage.
