An innovative method of forecasting the performance parameters of the Solar Water Pumping System

The design aspects and performance of the Solar Water Pumping Systems (SWPS) have been discussed already in earlier literature. But, unlike other authors, this paper is presented with the novelty of prediction of output parameters of SWPS like output energy of photovoltaic (PV) array, the energy in excess that can be supplied to the grid, load energy, and the discharge of water for irrigation. Non-linear curve fitting through the Polynomial Regression Analysis (PRA) method is used to achieve the above-said parameters. Primarily, the objective of this paper is to predict these parameters directly by using the solar insolation values. The predicted values of these parameters are compared with estimated values. This method of approach is used to reduce the complexity in the estimation of all the above parameters using the conventional procedure presented in this paper.
