  • Method and apparatus for controlling irrigation
    Patent number: 8620481
    Abstract: The invention comprises devices and methods for providing operational power to a solar-powered irrigation control system. In one aspect, a method includes producing electrical energy from light, storing the electrical energy in a capacitive module, and operating an irrigation controller using the stored electrical energy independent of another power source. In another aspect, a device includes a control system comprising a computer having a programmed irrigation schedule which operates at least one irrigation device, a photovoltaic power module, and a capacitive module connected to said photovoltaic power module to store the electrical energy provided by the photovoltaic power module, where the capacitive module provides power for the control system to operate the at least one irrigation device independent of another power source.
