ABSTRACT

Shortage of electricity is one of the main problem in the development of rural areas in Pakistan. Photovoltaic techniques are generally attaining an escalating attention and they're to become very competitive alternative, additionally, environmental issues such as population and global warming impact are attracting experts towards green electricity sources such as solar systems. A standout amongst the most imperative provisions of photovoltaic frameworks is for water pumping, especially in rural areas that have a considerable amount of solar radiation and have no access to national grids. They are generally utilized within household and animals water supplies and small-scale irrigation systems [1]. Water pumping from a PV array is a valid option to pollution-generating diesel and human-powered water pumps. PV-array water pumping can be fulfilled with or without a backup module. With a backup module, energy generated by the sun can be stored in the backup; hence, the application of the water pump can be fulfilled, even to a cloudy day, or at night to operate small loads. The application of photovoltaic is increasing in rural areas due to shortage, unavailability and costly electricity. Solar powered water pumps are commonly used in agriculture and residential level. This designed model deals with solar powered submersible pump. Among many available schemes, it consists of a PV panel, a storing backup, a variable-frequency inverter, a charge controller and induction motor coupled with a water pump. The inverter drives the induction motor, which drives the water pump. To obtain maximumoutput power of the Solar panel, the inverter is operated at variable frequency or soft start to minimize stall current of induction motor [5]. This designed model powers 0.75hp water pump. Different types of controllers can be used to increase frequency gradually from 0 to 50 Hz with 5 sec of delay each, thus voltage is controlled from 0 to 220V AC.
