Water stored in an elevated tank or diverted from a stream flows downward through a penstock, gaining speed as it falls. The spinning turbine shaft is connected to a generator, which houses magnets and copper wire coils; the relative motion between these components forces electrons to move, thereby generating an electric current.
Additional critical components include a intake screen to filter debris, a penstock pipe to channel water, and a charge controller to regulate the power sent to batteries. This pressurized water strikes the blades of a turbine, causing it to spin rapidly.

Flow rate, measured in gallons per minute (GPM) or liters per second, represents the volume of water passing a point per unit of time. A high head with moderate flow can generate significant power, whereas a low head requires a much larger flow rate to achieve the same result.
