SELECTION OF WEATHER PROFILE(S) FOR TESTING PERFORMANCE OF SPV PUMPS IN INDIAN CLIMATE

摘要

Indian climate is broadly divided into 4 climatic zones, Hot & dry, Hot & humid, Composite and cold & Cloudy. Due to escalated targets for SPV water pumping systems installation in the country there is a large demand for testing and certification of SPV pump samples. Indian test labs involved in testing and certifications are developing a generalized radiation and temperature profiles to cover the above 4 climatic zones such that the certified pump provide required performance in these climates. For testing samples quickly and yet ensure covering all climatic zones is with minimum number of profiles is an involved and challenging problem. This paper presents two profiles of radiation and temperature, representing summer and winter profiles, which is able to cover best and least performance of pump during a year. Further, using these two profiles performance data of two sample pump systems evaluated in-terms of PV array power output, quantity of water supplied (liters/watt/day), MPPT, Motor, pump and overall system efficiency.
