Tesla Motors Patents by Type

  • Publication number: 20180342640
    Abstract: A colored photovoltaic (PV) module or roof tile including a layer of highly stable nanoparticles provides uniform, angle-independent viewer color. The nanoparticles can comprise a metal oxide such as zinc oxide, titanium dioxide, or iron oxide. The nanoparticles can have composition and/or size tuned to absorb wavelengths of light reflected from PV cells, effectively concealing their appearance, and tuned to scatter wavelengths in a desired color range. The disclosed embodiments can provide better color uniformity and better efficiency, and be more cost-effective, than existing approaches for manufacturing colored PV modules. During the manufacturing process, a coating system, which may include one or more nozzles, can spray an inside surface of a glass cover with nanoparticles, which can be suspended in a solvent (such as water or isopropyl alcohol). The nanoparticle layer can then be encapsulated directly inside an encapsulant layer.

  • Patent number: 10141745
    Abstract: We describe a photovoltaic (PV) panel system comprising a PV panel with multiple sub-strings of connected solar cells in combination with a power conditioning unit (microinverter). The power conditioning unit comprises a set of input power converters, one connected to each sub-string, and a common output power conversion stage, to provide power to an ac mains power supply output. Integration of the micro-inverter into the solar PV module in this way provides many advantages, including greater efficiency and reliability. Additionally, embodiments of the invention avoid the need for bypass diodes, a component with a high failure rate in PV panels, providing lower power loss and higher reliability.

  • Publication number: 20180162199
    Abstract: An air vent assembly includes a cover member having an inlet for allowing a flow of air to enter the cover member. The cover member also has a vent extending from the inlet for allowing a flow of air to exit the cover member. The vent includes a first vent portion, and a second vent portion located adjacent to the first vent portion. The first vent portion has a first set of flow guiding vanes disposed therein. The second vent portion has a second set of flow guiding vanes disposed therein. Each of the vanes is spaced apart from one another and pivotally coupled to a pair of opposing walls of the cover member. The first and second sets of flow guiding vanes are independently moveable with respect to each other using an actuating mechanism for providing a variety of flow-guiding positions one of which includes a split flow-guiding position.
