摘要： A method of monitoring state of health for an energy generation system includes receiving a measurement of a parameter of an electrical component in the PV energy generation system at an instance in time, referencing a look-up table containing several values of the parameter representing an expected degradation trend across a progression of time for the electrical component, comparing the measurement to an expected value of the expected degradation trend for a period of time corresponding to the instance in time, and initiating a preventative measure based upon the comparison between the measurement and the expected value of the expected degradation trend.

摘要： A robotic controller for autonomous calibration and inspection of two or more solar surfaces wherein the robotic controller includes a drive system to position itself near a solar surface such that onboard sensors may be utilized to gather information about the solar surface. An onboard communication unit relays information to a central processing network, this processor combines new information with stored historical data to calibrate a solar surface and/or to determine its instantaneous health.

摘要： Photovoltaic module assemblies are mounted onto a solar tracker array torque tube via photovoltaic module brackets. The photovoltaic module brackets provide for stacking photovoltaic module assemblies in a nested configuration. The photovoltaic module assemblies are pre-assembled off-site, at a location different than the photovoltaic array installation site, and the nested configuration allows for efficient transportation of pre-assembled photovoltaic module assemblies to the installation site.

摘要： A power control system includes a first inverter power control system and a second inverter power control system coupled in a parallel configuration with the first inverter power control system. Both first and second inverter power control systems may each include an input configured to receive direct current (DC) power; a DC to alternating current (AC) inverter stage configured to receive the DC power input; an anti-islanding relay coupled to the output of the DC/AC inverter stage; and a transition relay coupled to the anti-islanding relay. The transition relay may be configured to route an output of the inverter power control system between one or more onsite back-up loads and an AC grid. The first inverter power control system may be designated as a master that is configured to control the operation of the second inverter power control system designated as a slave.

摘要： A system for energy conversion with electric vehicle (EV) charging capability includes a hybrid inverter comprising a DC/DC converter stage for receiving power from a photovoltaic array, a capacitor bank, and a DC-AC inverter coupled to the capacitor bank. The DC-AC inverter includes a battery pack connection for supplying energy to or receiving energy from a battery pack, an AC grid connection for supplying power to or receiving power from an AC grid, a connection for supplying power to a load, and an EV connection for supplying power to or receiving power from an EV battery. The system also includes a controller for generating control signals to control the flow of power within the hybrid inverter, which converts power received from at least one of the photovoltaic array and the battery pack and provides the converted power to charge the EV battery via the EV connection.

摘要： A targeted-annealing system can automatically cure a conductive paste that may bind cascaded strips of a string. The targeted-annealing system can include a first heat-treating bar that may be heated to a first curing temperature, and can include a second heat-treating bar that may be heated to a second curing temperature. During operation, a controller of the targeted-annealing system can activate one or more actuators to conform the first heat-treating bar to a top surface of two cascaded strips, and conform the second heat-treating bar to a bottom surface of two cascaded strips. The first and second heat-treating bars may be aligned along an overlap portion between the two cascaded strips, and can heat the overlap portion to 160 degrees Celsius.

摘要： Embodiments of the present technology may include a method to enable real-time data requests. The method may include subscribing to real-time data enable requests for a device on an energy generation (EG) network. The method may also include intercepting, from a requester, a request for real-time data for the device on an EG system within the EG network. The method may further include publishing a single request to the device to post a single measurement corresponding to the real-time data request. The single request may be published at less than or equal to a predetermined frequency for a request cycle that lasts for a predetermined duration.

摘要： A photovoltaic (PV) mounting system having a base portion that is substantially planar and having a first roof-facing side and an opposite module-facing side. The base portion has a lip that circumscribes the perimeter of the base portion and curves inward on the module-facing side. A clamp having a spring base is partially installed in the base portion and has a pair of clamping flanges extending upwardly from the base portion. A support beam comprising a pair of ledges adapted to mate with the clamping flanges of the clamp and a bottom portion that is supported by the spring base. A PV module coupling device is mechanically coupled to the support beam and configured for coupling to the frames of at least two photovoltaic modules.
