Key word: solar radiation, tilted radiation, Angstrom constants, solar potential, horizontal radiation, diffuse radiation, surface albedo.
Abstract: This study proposes a procedure that was adopted for the development of a linear regression model for estimating solar radiation on horizontal and tilted surfaces for 6 divisions in Bangladesh. The correlations, the simulated global solar radiation on tilted surface and the simulated diffuse solar radiation on a horizontal surface for each location are discussed elaborately. The solar radiation values obtained were compared with the measured values. The results of the global solar radiation show that the areas of greatest solar potential are Rajshahi > Dhaka > Sylhet > Chittagong > Khulna > Barishal and the months of the year with the highest tilted solar radiation are November, December, January and February.
