Thermal performance of small solar domestic hot water systems in theory, in the laboratory and in practice

The aim of the project is to present results of measurements and theoretical calculations for solar domestic hot water systems installed and tested in the laboratory and in practice. The solar domestic hot water systems from which results are presented are all based on small tanks. Further, reasons for poor thermal performances of systems tested in practice are given.

Based on theoretical calculations the negative impact on the thermal performance, due to a large number of different parameter variations are given. Recommendations for future developments of small solar domestic hot water systems are given.
