NettetIo = instantaneous level of solar radiation (insolation). Equation 4.7 represents collector efficiency and provides us with a comparable means of evaluating collector performance. You will find that comparing photovoltaic modules is a much simpler process. NettetThe model considers mass flow dependent thermal efficiency, pressure losses, leakage, system aspects, climate, and incidence angles at instantaneous working points. The model coefficients can be fitted from measurement data or test reports according to DIN EN ISO 9806 [5] or from simulation data within the workbook.
