Justifying the duration of operation of a solar and battery-powered sprinkler machine

The development of solar energy allows considering a possibility of using solar panels as the main power source for mobile machines. Especially for the machines used in open sunlit spaces, for example, for sprinkler machines. This article discusses a problem of justifying the parameters of a power supply in the form of accumulator batteries charged from solar panels while ensuring the required duration of operation of a sprinkler machine. Studies show that the duration of operation depends on the time of day when a sprinkler machine is started,its accumulator battery parameters, duration of the recovery charge, climatic zone and the area of the solar battery. Dependence of these parameters was found on the duration of operation of the electric drive of the support trolley of one section of the sprinkler machine, and a graphical solution to this problem is provided.
