  • Arc Detection and Prevention in a Power Generation System
    Publication number: 20210288610
    Abstract: A method for arc detection in a system including a photovoltaic panel and a load connectible to the photovoltaic panel with a DC power line. The method measures power delivered to the load thereby producing a first measurement result of the power delivered to the load. Power produced by the photovoltaic panel is also measured, thereby producing a second measurement result of power produced by the photovoltaic panel. The first measurement result is compared with the second measurement result thereby producing a differential power measurement result. Upon the differential power measurement result being more than a threshold value, an alarm condition may also be set. The second measurement result may be modulated and transmitted over the DC power line.

  • ENERGY HARVESTING AND ELECTRICAL POWER GENERATION
    Publication number: 20210203268
    Abstract: An apparatus for harvesting energy, such as solar, wind, wave, thermal, and the like, including a solar panel and a duct supporting the solar panel at an operational angle. The duct comprises a bottom shroud and side shrouds, therein forming a large aperture, a small aperture, and an oblique frustum shaped cavity. The oblique frustum shaped cavity is configured to direct a flow of fluid from the large aperture to the small aperture. A flow energy generator, such as a turbine, located at the small aperture is configured to collect flow energy. Temperature differences between the solar panel and the environment may be used to harvest thermal energy with a thermoelectric generator. Fluid flow under the solar panel may decrease the panel temperature and increase the efficiency. Generators may be operated in reverse to lower the solar panel temperature and increase efficiency.
