Some studies on performance analysis of two different laboratory scale solar photovoltaic water pumping in irrigation systems

By considering the limitation of the conventional energy resources, renewable energy plays an important role today. The agriculture procedure is totally dependent on the good irrigation process and the irrigation process is on the energy sources. Solar photovoltaic pumping can provide the necessary alternative way. With the advancement of the technology, so many pumps are available in the market which can be used for solar pumping operation. In this study, two different types of pumps are taken for experimental purposes. One pump is diaphragm type reciprocating pump and another one is centrifugal pump. The experiment is carried out for four months. Based on the result, different characteristics are represented for three different pump discharge pressure. The main objective of this study is to make the comparison of different parameters like efficiency, minimum intensity required for pumping operation etc for two pumps. Based on this result, finally to see which pump is suitable for photovoltaic operation and at which condition. To best of our Knowledge this is the first time such type of comparative work on laboratory scale solar photo voltaic (SPV) water pumping systems for irrigation purpose was reported.
