Abstract: A numerical model for a solar water heating system (SWHS) used in industrial process heat in warm climates was carried out and validated with experimental data. The experimental set up consisted in 18 evacuated tube solar collectors, 700 lt thermal storage tank, 10 kW back up auxiliary heating system (electrical), plate heat exchanger coupled to a 25 kW chiller (in order to simulate the industrial process heat), differential temperature control and recirculation pumps. In this work, a TRNSYS type was developed in order to take into account the thermal losses in connecting pipes between the storage tank and the solar collector array.
