UV Degradation in Material Testing
The effects of UV degradation on materials that require a long service life can be measured with accelerated exposure tests. With modern solar concentrator technologies, it is possible to simulate 63 years of natural UV radiation exposure on a test device in a single year. In Solar Power Modules degradation is a long-term issue according to material testings; the efficiency loss by UV degradation is about 6.81 to 9.54% in 20 years.

Famous quotes containing the words degradation, material and/or testing:
“We found nothing grand in the history of the Jews nor in the morals inculcated in the Pentateuch.... I know of no other books that so fully teach the subjection and degradation of woman.”
—Elizabeth Cady Stanton (1815–1902)
“Man’s characteristic privilege is that the bond he accepts is not physical but moral; that is, social. He is governed not by a material environment brutally imposed on him, but by a conscience superior to his own, the superiority of which he feels. Because the greater, better part of his existence transcends the body, he escapes the body’s yoke, but is subject to that of society.”
—Emile Durkheim (1858–1917)
“Now I see that going out into the testing ground of men it is the tongue and not the deed that wins the day.”
—Sophocles (497–406/5 B.C.)
