While most solar collectors focus only on one solar collection method, the small hybrid system uses a flat plate collector in conjunction with five evacuated tubes to absorb the most energy possible from both direct and diffuse solar radiation. Data was collected over four months while the system operated at different flow rates and with various levels of available insolation from the sun to evaluate the performance of the solar collector. To understand the relative contribution of the flat plate collector and the evacuated tubes, temperature differences across each part of the system were measured. The results indicate the average first law efficiency of the hybrid system is 43.3%, significantly higher than the performance of the flat plate alone. An exergy analysis was performed for this system to assess the performance of the flat plate system by itself. Results of the second law analysis were comparable to the exergetic efficiencies of other experimental collectors, around 4%. Though the efficiencies were in the expected range, they reveal that further improvements to the system are possible."},{"label":"DOI","value":"10.4236/sgre.2018.912016"},{"label":"Volume","value":"9"},{"label":"Publication Date","value":"D:00 M:00 Y:2018"},{"label":"Author Supplied Keywords","value":"Solar Thermal Energy, Flat Plate Collector, Evacuate Tube Collector, Exergy, Second Law of Thermodynamics"},{"label":"Publication Information","value":"© 2018 Heather Dillon et al.
