Abstract:
A system for monitoring and wirelessly transmitting solar array parameters such as current, voltage and temperature in real time is primarily housed within a recombiner box. The system lends itself to retrofitting within some commercially available recombiner boxes. Signals emitted from the RF controller component of the system are received by a central processor, which includes a dashboard interface. Multiple systems in proximity can be linked to form a mesh network with one central processor.
Abstract:
A wire harness connects multiple solar panel junction boxes to a recombiner box. The wire harness includes in-line fuse assemblies, with optional blocking diodes, so each string of solar panels is associated with one fuse. In the event of a blown fuse, only one upstream solar panel string is affected. Entire wire harnesses and/or individual in-line fuse assemblies can be easily swapped out, thereby decreasing the time and expense of troubleshooting and repairing.
Abstract:
A monitoring system for and method of preventing electrical arcs in a solar energy system is disclosed. The monitoring system includes an insulation resistance (IR) monitoring device, a disconnect switch, a power supply, an indicator, and optionally a communications interface. A method of preventing electrical arcs in a solar energy system using the monitoring system may include, but is not limited to, the steps of providing and installing the monitoring system in a solar energy system; activating the solar energy system and the monitoring system; continuously monitoring the insulation resistance of a conductor; if the lower and/or upper resistance threshold of the IR monitoring device is not satisfied, then transmitting a shutdown signal to the disconnect switch, thereby turning off the power to the affected circuit, and indicating the presence of the potential fault condition.

Abstract:
A disconnect system for a solar installation shuts down power upstream from an inverter, so that it is safe for solar field personnel to perform work related to a solar installation. The system actuates multiple disconnect devices in one motion by a linkage assembly which can associate 2-4 disconnect switches with a single handle. This system preferably includes hardware and logic for monitoring the current and voltage output of electrically coupled combiner/recombiner boxes in the solar field, and for wirelessly transmitting this data to a user. A single disconnect cabinet can accommodate 2-20 inputs from associated lead assemblies and/or recombiner lead assemblies with 5 handles or less.
Abstract:
A base is a platform that supports a component off the ground in a solar energy installation. The specific configuration of a base can vary based on the intended component, for example whether it holds a transformer or power component. Multiple bases are mechanically and/or electrically connected to form a system of bases in the field. Proper placement of bases and engagement of those bases is facilitated by mating alignment mechanisms such that one base can be lowered “fit” with another. A method of positioning components includes positioning a base and aligning and lowering a second base alongside the first such that the bases engage.
Abstract:
A junction box is affixed to, and electrically coupled with, a solar panel. The junction box is configured to releaseably engage and disengage accessory modules, thereby allowing accessory modules to be replaced or exchanged easily. Accessory modules are electrically coupled with other accessory modules in the solar panel string. The furthest downstream accessory module is connected to a wire harness, which is connected to a central combiner box.
Abstract:
Low leakage electrical joints and wire harnesses for simplifying the electrical infrastructure associated with solar energy utilities are disclosed. The low leakage electrical joints include fused wires that have been sealed, encased and configured to plug into other joints to form wire harnesses. The wire harnesses are particularly well suited for coupling a plurality of solar collector junction boxes to a combiner box.

Abstract:
In general, this disclosure describes a system and method that includes a set of photovoltaic panels that includes two or more photovoltaic panels electrically coupled together. Each photovoltaic panel has a physical connection with at least one other photovoltaic panel in the set of photovoltaic panels and each photovoltaic panel in the set of photovoltaic panels has a mechanical interface configured to interface with a mounting structure. The system further includes a dispenser that comprises a guide configured to align the physical connection of one or more of the photovoltaic panels in the set of photovoltaic panels with receiving hardware of the mounting structure. The dispenser is configured to house the set of photovoltaic panels and sequentially dispense each photovoltaic panel onto the mounting structure as the dispenser moves along a length of the mounting structure.
