Introduction Solar Photovoltaic Water pumping system (SPVWPS) is an ideal alternative to the electricity and diesel based water pumping systems. It has been a promising field of research for last fifty years. In the 1970 decade, efforts were made to explore and study the economic feasibility, and practicality of SPVWPS.
Solar photovoltaic water pumping system (SPVWPS) has been a promising area of research for more than 50 years. In the early 70s, efforts and studies were undertaken to explore the possibility of SPVWPS as feasible, viable and economical mean of water pumping.
Furthermore, the use of solar photovoltaic power to operate the water pumping system is the most appropriate choice because there is a natural relationship between requirement of water and the availability of solar power . SPVWPS comprises of different components, which can be grouped as mechanical, electrical and electronic components.
The installed peak power is 3000 Wp. Ghoneim A. A. used optimum parameters for a solar pumping system to meet water requirements of 300 people in a remote area of Kuwait. 12 m 3 of water is to be pumped every day for the community, assuming water requirement of 40 l/person/day.
Direct driven solar PV water pumping system is shown in Fig. 4. In this system, electricity generated by PV modules is directly supplied to the pump. The pump uses this electric power to pump the water. As no backup power is available, the system pumps water during the daytime only when the solar energy is available.
Optimization of overall solar PV water pumping system The efficiency of solar PV panel is usually very low (10–18%), hence the PV power should be utilized very efficiently. This is achieved by selecting each component of SPVWPS with optimum operating parameters.
A solar cell is a semiconductor device that can convert solar radiation into electricity. Its ability to convert sunlight into electricity without an intermediate conversion makes it unique to harness the available solar energy into useful electricity. That is why they are called Solar Photovoltaic. The sunlight is a group of photons having a finite amount of energy. For the generation of electricityby the cell, it must absorb the energy of the photon. The absorption depends on the energy of the photon and the band-gap energy of the solar semiconductor. A wide variety of solar cells are available in the market, the name of the solar cell technology depends on the material used in that technology. Hence different cells have different cell.

Due to the limitations of the process conditions, lithium-ion battery pack between the cells even after selection, there is always a certain difference, after several charge and discharge cycles or long-term shelvin.
The lithium-ion battery pack is composed of multiple single lithium-ion batteries connected in series. Due to the differences in the cells, when the terminal voltage rises inconsistently when charging in series, some cells will be overcharged and some cells will be undercharged.
Whenever possible, using a single string of lithium cells is usually the preferred configuration for a lithium ion battery pack as it is the lowest cost and simplest. However, sometimes it may be necessary to use multiple strings of cells. Here are a few reasons that parallel strings may be necessary:
When the lithium-ion battery pack is produced and stored for a long time, due to the difference in static power consumption of each circuit of the protection board and the different self-discharge rate of each battery cell, the voltage of each string of batteries in the entire battery pack is inconsistent.
