The objective of this paper is to evaluate the performance characterization of solar thermal technologies based on solar radiation analysis correlating Global Horizontal Radiation, Global Tilted radiation, Diffused Radiation, Ambient temperature, DNI and Sunshine hours at Leh_Ladakh, Gujarat_Gandhinagar and Chennai stations. The present work involves annual analysis of radiation/weather data based on the parameters covered above and characterization of solar thermal technologies i.e. Flat Plate Collector, Evacuated Flat Plate Collector and 1.5x Non Imaging Concentrator Collector or compound parabolic concentrator based on technology specification. Month wise variation of Energy Gain, at different operating temperature is calculated, and a comparative simulative analysis is performed for different solar thermal collector technologies. Also, predicting the cost effective technology for a given range of operating temperature in different climatic conditions. By the use of the computer program MS Excel the amount of the produced heat energy for a simple Flat Plate Collector, Evacuated Flat Plate Collector and for 1.5x Non-imaging Concentrator collector has been calculated at different operating temperature and the results are presented.

Keywords: Evacuated Flat Plate Collector, Flat Plate Collector, 1.5x Non imaging Concentrator Collector.
