Pump Controller
The term ‘pump controller’ can be used to mean any one of the following. The controller functions to turn the pump on and off electrically. This device can be a programmable timing device, or its ‘on-off’ function can be activated by a ‘float’ switch triggered by the water storage level in or discharge into a […]
Maximum Power Point Tracker – MPPT
The power output of a solar array is used or manipulated by the components to which it is connected. A maximum power point tracker (MPPT) can be installed between the array and the electric motor to match the PV array’s output with the required current or voltage of the motor to be operated. An MPPT […]
Solar Array Output
The amount of power a solar array generates is directly proportional to the solar resource available throughout the day. Two critical calculations can be performed to determine the system yield: Power output (instantaneous output)Power output = instantaneous solar radiation (kW/m²) x rated array power (kW) x system efficiency Energy output (output over time)Hourly energy output […]
