Abstract:
1. A method for providing a solar power array device without blocking diodes, the method comprising: providing a solar module; connecting a solar array tracker and a circuit breaker to the solar module; connecting a power bus and a controller to the circuit breaker; connecting an inverter to the power bus; sensing with the controller the output voltage and current of the solar module, wherein when the controller senses the solar module is producing power below a power threshold level, the controller sends a signal to the solar array tracker to vary the solar module's pointing until the solar module is operating at its maximum power point for the solar module's level of illumination; and determining, with the controller, an amount of shadowing on the solar module by using the output voltage and the output current of the solar module, wherein when the controller determines that the amount of shadowing on the solar module is less than a minimum shadowing threshold level, the controller sends a command to the circuit breaker to prevent current flow into the solar module.
