Most PV-pumping systems consist of a PV array, a water pump, a pump controller and a storage tank. Optional components include water level sensors or float switches. PV arrays are comprised of PV modules that range in size from 50 to 80 watts. The PV modules are the most reliable component in any pumping system. There are many reliable DC power centrifugal and positive displacement or diaphragm pumps designed to operate with PV power supplies.
Centrifugal pumps are good for pumping medium to large volumes of water.
PV powered diaphragm pump's flow rate is directly related to the motor speed. Pump Controllers, maximize the water delivery of pumping by matching the voltage and current output of the PV array to the requirements of the pump motor. Storage tanks, for stock watering applications - round open tanks of galvanized steel, cement or clay bottoms are typically used. Our team of experienced technicians will be glad to schedule a site evaluation at no cost or obligation to you. This consultation will help you determine your water requirements and cost options for a PV system to meet your needs.
