  • Patent number: 10666161
    Abstract: A safety shut-down system for a solar energy installation includes a DC to AC inverter converting DC power from a photovoltaic solar array to AC power and generating remote control signals to enable or disable the flow of DC power from each individual photovoltaic panel or string of panels to a photovoltaic output circuit. One or more manual switches, one of which may be at a service entrance for electrical power to the installation, are operative to cause the DC to AC inverter to disable all DC power from the photovoltaic solar array; this also occurs when the DC to AC inverter is shut off. A storage battery may selectively receive DC power from one or more photovoltaic panels or strings of panels for charging. The DC to AC inverter may generate AC power from the battery when the photovoltaic solar array is disabled.

  • Patent number: 10648190
    Abstract: A modular ballast system for supporting objects uses tubing such as pipes of appropriate size for the required ballast. Once in place, the empty pipes are filled with a watery mix (slurry) of sand, silt, gravel, soil, cement or other generally available material to generate a majority of the ballast weight. A two piece clamping mechanism provides fixed placement attachment points suitable for attachment by supported structures. The lower piece of the clamping mechanism sits under the ballast tubing and is designed to both support and disperse the anticipated weight of the objects with minimal impact on the surface beneath it. The upper piece of the clamping mechanism mates to the lower clamping piece and completes a full 360 degree collar around the ballast tubing to create a durable clamping mechanism that both captures the weight and position of the ballast tubing and prevents the ballast tubing from shifting.

  • Patent number: 10639744
    Abstract: A new ultrasonic aided laser joining method (UAL) for bonding dissimilar materials has been developed. The method is capable of eliminating the laser-induced bubbles at the bonding faces and to improve the joint strength over that of the conventional laser-assisted metal and plastic joining method (LAMP). Some experiments on joining titanium to polyethylene terephthalate have been conducted to show the superiority of UAL over LAMP. The results showed that the joint strength, measured in terms of failure load, was significantly increased when ultrasonic vibration was employed during laser joining. For the LAMP joined specimens, fracture normally occurred at the metal-plastic interface, whereas for the UAL joined specimens, fracture normally occurred in the parent plastic part. The improvement in joint strength is mainly due to the elimination of pores in the resolidified plastic.

  • Patent number: 10593824
    Abstract: A method for making an ultra-thin, flexible crystalline silicon solar cell from thick, inflexible cells. A thick, inflexible cell having a plurality of electrical contacts on the back side thereof is adhered to a mount by means of a temporary bonding adhesive tape and a thickness of the mounted stack. A thickness of the bonding tape and the back-side contacts is determined and compared to a desired thickness of the final cell. Excess material is ground from the front side of the stack to obtain a thinned stack having the desired thickness and the thinned stack is removed from the mount to produce an ultra-thin, flexible rear-contact Si solar cell having a total thickness of less than 80 ?m and a bending radius of less than 20 mm. The front surface can be textured, with a passivation layer and/or a dielectric layer being deposited thereon.

  • Patent number: 10591216
    Abstract: A solidifying device is for solidifying a substrate which includes a middle and two side portions. The thermostability of the middle portion is greater than that of the side portions. The solidifying device includes a housing, a heating member, a temperature control air-floating member and a conveyor. The housing defines a working space. The heating member is in the working space. The substrate has a heat receiving surface facing the heating member. The temperature control air-floating member is in the working space and below the heating member. The conveyor is for transporting the substrate into the working space and between the temperature control air-floating member and the heating member. The heating member is for providing heat to the substrate. The temperature control air-floating member is for supplying air towards the substrate to allow the substrate to float in the working space and form a high-temperature and two low-temperature areas.
