This letter proposes a novel and simple method for estimating solar radiation, named the ‘three‐point method’. The three points used to form the model are sunrise, sunset, and the maximum radiation point. The issue of obtaining maximum radiation is performed with the weighting evaluation of the HOTTEL and ASHRAE models. The feasibility and effectiveness of the proposed model is shown by simulation results. This model is equally applicable in any part of the world with a reassessment of the weighting factors for the maximum radiation. © 2012 Institute of Electrical Engineers of Japan.
