摘要: Abstract Daily and hourly diffuse radiations measured using a pyranometer shading ring have been compared with the values calculated several correlations. For daily radiation, correlation of Duffie & Beckman ( Solar Engineering Thermal Processes , John Wiley, 1980), Liu Jordan Energy 4 (3) (1960) 1–19), Erts et al. 28 (1982) 293) Bruno 20 (1) (1978) 97–100) used while radiation was correlations Hottel, Orgill Holland 19 (1977) 357) Jordan. It has uniformly observed that Jordan's method may be considered suitable for estimation in clear-sky conditions plain areas northern India.
