A New Method to Determine the Annual Energy Output of Liquid-Based Solar Collectors

Mirosław Żukowski , Paulina Radzajewska


This article presents a new way of determining the annual energy output of solar thermal collectors. The proposed method, in the first stage, assumes the creation of a database that contains energy gains QSC from the solar collectors, the average annual solar irradiance intensity IS, and the average temperature of the outside air θO. It can be made on the basis of detailed computer simulations. In the current case, EnergyPlus software was used to create this database. Next, mathematical relations for flat plate and evacuated tube collectors were developed using the linear regression analysis (multiple regression method). Based on these equations, one can calculate the value of QSC as a function of IS and O. In addition, two graphs for the estimation of the annual energy gains for the entire area of Poland and for the conditions of a typical meteorological year were prepared
