Abstract: Photovoltaic mounting systems that form chemical flashings are provided herein. Such sealant injection systems provide directional control and containment of sealant flow to form a chemical flashing that improves sealing of roof penetrations. Such systems can include a base assembly adapted to mount to a roof surface and support a mounting bracket having a photovoltaic module coupling device. The base assembly can include a sealant guide, a compressing plate and a sealant cartridge held between the guide and compressing plate by one or more coupling features of the guide. The coupling features can include a first set of features, such as a series of tabs, that facilitate coupling between the guide and the compressing plate. The base assembly can further include a base that releasably couples to the sealant guide by a second set of coupling features. Methods of mounting such base assemblies on roof surfaces are also provided.

Abstract: An apparatus and system for quickly and easily assembling PV modules into a PV array in a sturdy and durable manner. In some embodiments, the PV modules may have a grooved frame where the groove is angled into the frame with respect to the planar surface of the modules. Various components may engage within the angled groove to assemble the PV modules into the PV array using what may be referred to as a pivot-fit connection between the components and angled groove. Other embodiments may operate with PV modules having frames without angled grooves as by use of wraparound brackets.

Abstract: A system for mounting a photovoltaic array onto short sections of mounting rails such that a section of mounting rail is only installed fewer than all the photovoltaic modules in the array. A single section of mounting rail may support one, two or three photovoltaic modules depending on it's length and position respect to the edge of each module frame.

Abstract: We describe a modular adjustable power factor renewable energy inverter system. The system comprises a plurality of inverter modules having a switched capacitor across its ac power output, a power measurement system coupled to a communication interface, and a power factor controller to control switching of the capacitor. A system controller receives power data from each inverter module, sums the net level of ac power from each inverter, determines a number of said capacitors to switch based on the sum, and sends control data to an appropriate number of the inverter modules to switch the determined number of capacitors into/out of said parallel connection across their respective ac power outputs.

Abstract: Systems and methods for fabricating a photovoltaic structure are provided. During fabrication, a patterned mask is formed on a first surface of a multilayer body of the photovoltaic structure, with openings of the mask corresponding to grid line locations of a first grid. Subsequently, a core layer of the first grid is deposited in the openings of the patterned mask, and a protective layer is deposited on an exposed surface of the core layer. The patterned mask is then removed to expose the sidewalls of the core layer. Heat is applied to the protective layer such that the protective layer reflows to cover both the exposed surface and sidewalls of the core layer.

Abstract: A string-forming system is described. The string-forming system may include at least a first cell-lifting mechanism and a second cell-lifting mechanism that can automatically arrange a set of strips of a photovoltaic structure into a cascaded formation. During operation, a controller can cause the first cell-lifting mechanism to lift a first strip from a first platform, and can cause the second cell-lifting mechanism to lift, from the first platform, a second strip that may follow the first strip on the first platform. The controller may then activate a first shifting actuator of the first cell-lifting mechanism or a second shifting actuator of the second cell-lifting mechanism to place a leading edge of the second strip above a trailing edge of the first strip.

Abstract: The disclosure describes various stackable corner protector configurations. The corner protectors can have curved lateral surfaces that allow the corner protectors to be decoupled from a photovoltaic module to which they are coupled to by rotating one end of the corner protectors away from the object. This removal process works even more efficiently with multiple stacked corner protectors as the stacked corner protectors can be concurrently removed from the object by rotating the stacked corner protectors away from the object together. The corner protector can also include one or more attachment features for securing the corner protector to the object. For example, when the corner protector is installed on a photovoltaic module, the attachment feature can engage a lip defined by a recess or channel of the photovoltaic module.
