Abstract

In this paper, a study was carried out for the effect of local atmospheric condition and tilt angle on the energy yields of solar collectors at selected latitudes. A computer program was developed for that purpose to find the daily average, monthly, seasonal and annual energy profiles based on Klein model and Erbs correlation. Using generic system of solar collector at due south, hybrid energy yields: electric, heating and cooling were obtained. As a case study, the results were presented for latitudes 30o - 37o N. Optimum tilt angles were found to be within 0o to 66o which nonlinearly depends on the relevant time period of the year and atmospheric condition. Two important findings were concluded. First, optimum angles would be larger for better atmospheric conditions with greater shifts during winter period while summer months are of less sensitivity. This shift was 10o - 14o for winter monthly energy, 0o - 8o for summer monthly energy, 11o - 13o for total annual and heating energy and 1o - 3o for total cooling energy. Second, deviations in the angles of commonly used empirical formulas were noticed to be larger in summer period and higher latitudes. These deviations were in the range of -10o to +20o as compared to the corresponding values of present study. Finally, average energy values were 6055, 1700 and 2370 MJ/m2 for annual, heating and cooling yields respectively.
