This is a simple and easy-to-wheel solar-power herbicide/pesticide sprayer that uses a 12 Volt, 20 Watts solar panel with a detachable battery of 12Volts, 5 Ampere-Hour, and 5 Ampere-Hour charge controller. The mechanical component is operated by wheeling the machine manually.
The spraying is operated using a two-step push button that energizes a submersible liquid pump, and solenoid valves for two or four-nozzle spray at the first or second press.
