A water pumping system needs a source of power to operate. In general, AC powered
system is economic and takes minimum maintenance when AC power is available
from the nearby power grid. However, in many rural areas, water sources are spread
over many miles of land and power lines are scarce. Installation of a new transmission line and a transformer to the location is often prohibitively expensive. These systems are portable and easy to install maintenance, and furthermore
diesel fuel is often
expensive and
not readily available in rural areas of many developing countries.
The use of solar PV
Module
for
water pumping is one of the most attractive
applications due to several advantages. In general a solar water pumping system
consists of PV modules, Motor, Pump, Inverters and storage tank. The storage tank can be thought of as an energy storage media
like batteries. Therefore the use of battery is not required for water pumping application. Also a DC motor can directly
be coupled with a solar PV Panel avoiding the use of an inverter. An AC Motor can
also have a maximum
power point tracking (MPPT) device.
