(2) The main drawback of this and other similar models [2, 3] is the need for solving systems of equations which are obtained by fitting a large number of numerical simulation data. <...> All rights reserved c – 224 – Maxim A.Yakunin A hybrid method for evaluating absorbed solar energy at the Surface Level . it is impossible to evaluate <...>
