Analysis of tilt angle variation in solar photovoltaic water pumping system

Abstract

The paper considers the optimum tilt angle and orientation for the maximum utilization of the solar energy to collect more solar radiation for water pumping application in remote area. The module of tilt angle should be varied from 0° to 45° due to the single-axis tracking system. This paper deals with the effect of tilt angle variation in solar-water pumping system technologies. For this purpose four different tilt angles 8°, 15°, 30°, and 45° have been considered. The total amount of water to be extracted to the fixed tilt angle depends upon the latitude of the site and compared to different tilt angles which are suitable for the better performance of solar PV water pumping system. The performance analyzing models are designed using PVsyst simulation software. A comparative analysis is performed for different tilt angles with respect to solar yield, performance ratio, and energy losses to fulfill the irrigation system and domestic water demand. The software simulation indicated that the 30° orientation of PV panel provided maximum solar radiation and gives better performance.
