PNS/BAFS 324:2022 Solar Powered Irrigation System — Specifications

the tilt of the PV module with respect to the horizontal plane

angle of inclination

link between motor pump and solar generator that regulates the operation of PV array to pump and is classified into two types: inverter (directly connected to pump set) and charge controller (with batteries)

controller

controller directly connected to the pumpset

inverter

controller directly connected to the battery

charge controller

monitors the charging and discharging of the battery connected to the PV array

charge controller

converts direct current (DC) from PV module to alternating current (AC)

inverter

composed of PV modules connected in combination of series and parallel connections, which convert energy from the sun into electrical energy

photovoltaic (PV) array

assembly of photovoltaic cells mounted in a frame that uses sunlight as a source of energy to generate a DC electricity

PV module or solar panel

ratio of the input solar power to the PV module and the output power of the inverter/controller

PV performance ratio

the angle with which a ray of sunlight strikes the surface of the PV module, measured with respect to a line perpendicular to said surface

ray of incidence

temporary water storage that adds kinetic energy to facilitate water distribution. This is also known as a water tank

reservoir

amount of solar energy received by or projected onto a surface, expressed in Watts per square meter (W/m2)

solar irradiance

the vertical distance from the free suction water level to the center line of the pump suction

suction lift

ratio of the output power of the pump set and the total solar input power

system efficiency

measure of energy increase imparted to the water by the pump and expressed by the algebraic difference between the total discharge head and total suction head, expressed in meters (m)

total dynamic head or total head

Pumpsets in which suction inlets are not submerged in water.

surface pumpset

Pumpsets installed below water level.

submersible pumpset
