Estimation of the Monthly Standard Diffuse and Universal Solar Eradiation for the City Varanasi, Uttar Pradesh, India

Solar radiation data is important for supposing power capacity that can be set up from photovoltaic unit. Solar radiation tumbling on the earth’s exterior is consistent by an equipment called a total radiometer. This paper describes the process for the development of monthly standard universal and diffused radiation for the city Varanasi in Uttar Pradesh, India. It can be located at Longitude: 82.9738° E and Latitude: 25.3076° N at an elevation of 81 meters. The Gopinathan model has been used for the calculation of values of the monthly standard universal cosmic radiation. Gupta and Kreith’s models have been used for estimating the values of monthly standard diffuse cosmic radiation. The calculated data has been analyzed and the result has been simulated through MATLAB.
