  • Patent number: 6101716
    Abstract: A new evaporative cooler solar retrofit kit for taking an evaporative cooler off of an electrical power grid, thus reducing the amount of electrical power supplied by such a grid, and reducing the cost of operating such a cooler. The inventive device includes a solar panel which is mountable on the housing of the evaporative cooler, a dc motor for replacing the existing blower motor, and a dc motor driven pump for replacing the existing pump motor and pump. The solar panel is electrically coupled to the dc motor and to the dc motor driven pump, such that the electricity generated by the solar panel provides the electricity for operating the evaporative cooler. Therefore, the cooler utilizes energy provided by sunlight, which reduces the use of commercially supplied energy. The cooler will operate from sunrise to sunset when air cooling is most required.
