solar conversion kit
The project entails replacing the gasoline engine of a used 22" gas powered mower with a 12 Volt electric motor and battery - along with gauges, circuit breaker/power switch and charging connector. Using 12 Volts keeps the design simple and relatively safe.
The solar charging system consists of solar panel(s) that are wired to a charge controller with an extension cord that connects to the mower. Optionally, a standard AC powered automatic battery charger can be used.
The noticeable difference when mowing is the quiet! The blades are spinning at about 1/2 the speed (1750RPM) of a gas mower (3450RPM) with a virtually silent motor, it sounds like a big fan! With sharp blades it cuts just as good as my retired Sears 5HP mower.
The Electric Power Research Institute of Palo Alto claims that replacing half of the nearly 1.3 million walk-behind gas mowers used in the United States with electric mowers would eliminate the equivalent hydrocarbon emissions of 2 million cars.
