In this paper, a new method based on the empirical equations is introduced to estimate the monthly average daily global solar radiation on a horizontal surface. The proposed method uses Intelligent Water Drops Algorithm as a swarm-based nature-inspired optimization technique. The best coefficients of linear and nonlinear empirical models and global solar radiation are calculated for seven different climate regions of Iran using proposed algorithm written in MATLAB software. The results of the proposed method are compared with other techniques. The result shows that the proposed method is more accurate in estimating the monthly average daily global solar radiation.
