Abstract
One factor of great relevance for the applicability of the collectors is their thermal efficiency. This characteristic can be affected by several factors, such as the ambient temperature, the flow rate and the solar radiation. In this work, we intend to evaluate the influence of solar radiation on the efficiency of a flat plate collector. We selected a model available in the national market, which has frequent characteristics among models of the same category. Experimental tests were carried out using a solar simulator, varying the intensity of simulated solar radiation in the range of 700 to 1000 W / m², allowed by ABNT NBR 15747: 2009. The other test conditions were not altered. From the obtained data, the thermal efficiencies and the specific monthly productions of energy were calculated with the objective to verify in which range of solar radiation the flat plate collector presented better performance.
