Experimental study on the durability of composite materials collectors of solar energy

Abstract

Experimental research on durability conducted to determine the life of the composite material absorber solar collector (SC) under natural climatic conditions; the ability of the design
to keep operating until the end of the period specified in the terms of the margin needed to preserve functional properties. SK investigated absorbers made of composite materials for solar
collectors, which included basic component, fillers, and binders. During the tests measured: temperature in a heat chamber of artificial weather; energy radiation coming from the radiation
source unit sample surface; temperature and pressure of the internal liquid medium experimental design; including the test and the destruction of the sample.
