Descent control and energy recovery system for solar panel cleaning system

摘要

System and method for cleaning solar panel rows, with electronic descent control and potential energy recovery system, operating by modulated switching signals to an electronic switching device that converts DC output of a DC motor/generator to alternating current that is transferred through a transformer and rectifier to charge the system's battery. An impedance load on the DC motor/generator is generated during downward movement of the system' s cleaning apparatus in order to control the descent rate of the cleaning apparatus.
