Abstract

Ministry of New and Renewable Energy, Govt. of India has set a target of 100 giga watts (GW) power from solar power till 2022. Hence, the importance of solar radiation resource assessment. Ground-based solar radiation measurement and its quality plays an important role in the study of estimation of solar radiation and forecasting of solar power produced. In this paper hourly averaged solar irradiance data on a horizontal surface, measured at Indian Meteorological Department weather station for the hot and dry region, Jodhpur (India) is analyzed for the month of August, 2015. Data quality check is done in two stages where, at the first stage, solar irradiance is taken in original form, and then in the second stage BSRN standard guidelines, coherence and correlation tests are applied. Data quality check of ground-based solar radiation data for Jodhpur during rainy season (month having highest error/disturbances) highlights the need to include other weather parameters such as rainfall data. The results are compared with other available data, and some suggestions for data quality improvement are discussed.
