Abstract: A photovoltaic energy system includes a photovoltaic field configured to convert solar energy into electrical energy, one or more solar intensity sensors configured to measure solar intensity and detect a cloud approaching the photovoltaic field, and a controller. The controller receives input from the solar intensity sensors and predicts a change in solar intensity within the photovoltaic field before the change in solar intensity within the photovoltaic field occurs. The controller is configured to preemptively adjust an electric power output of the photovoltaic energy system in response to predicting the change in solar intensity within the photovoltaic field.

Abstract: A method and apparatus is disclosed for intelligently inverting DC power from DC sources such as photovoltaic (PV) solar modules to single-phase or three-phase AC power to feed the power grid for electricity generation. A number of smart single-input, dual-input, triple-input, quad-input, and multiple-input power inverters in a mixed variety can easily connect to single, dual, triple, quad, and multiple DC power sources, invert the DC power to AC power, and daisy chain together to generate a total power, which is equal to the summation of the AC power supplied by each smart and scalable power inverter of this invention.
